Background: For a long time, the prevailing viewpoint suggests that shorter telomere contribute to chromosomal instability, which is a shared characteristic of both aging and cancer. The newest research presented that T cell immune deficiency rather than chromosome instability predisposes patients with short telomere syndromes to some cancers. However, the relationship between genetically determined telomere length and immune cells remains unclear. Methods: The two-sample Mendelian randomization (MR) analysis was conducted to elucidate the potential causal relationship. The genetic data of telomere length and the quantity of lymphocytes were obtained from the Genome-Wide Association Study. The inverse variance-weighted method was used to estimate the effects primarily and another four methods were as a supplement. Relevant sensitivity analysis was used to test the results. Results: The IVW method showed a significant correlation between telomere length and the percentage of T lymphocytes (OR: 1.222, 95% CI: 1.014-1.472, P = 0.035), indicating that short telomere length significantly increases the risk of low T cell percentage. Further analysis of T cell subsets indicated that shorter telomere length may primarily lead to a lower proportion of Natural Killer T cells (OR: 1.574, 95% CI: 1.281-1.935, P < 0.001). Analysis of B cell subsets revealed that shorter telomere length may be associated with a higher proportion of Naive-mature B cells, and a lower proportion of Memory B cells. And the sensitivity analysis indicated the validity and robustness of our findings. Conclusion: In summary, a causal relationship existed between telomere length and the quantity and differentiation of immune cells. Specifically, genetically predicted shorter telomere length was found to increase the risk of occurrence of immunosuppression and immunodeficiency.

Objectives:The purpose of this study was to examine the proportion of CD161 on CD56+Natural Killer(NK) cells in peripheral blood of primary Sjögren’s syndrome(pSS) and investigate its clinical relevance of pSS. Methods:The proportion of CD56+NK cells and CD161 on CD56+NK cells was detected by flow cytometry in 31 pSS patients and 29 healthy controls (HCs). The correlations between proportion of CD161+CD56+NK cells and clinical features and disease activity of pSS were further analysed. Meanwhile, we drew the receiver operating characteristic(ROC) curve to evaluate the diagnostic value of CD161+CD56+NK cells in pSS. Results: The proportion of CD56+ NK cells and CD161+CD56+NK cells decreased markly in pSS patients compared to HCs. The correlation analysis showed that proportion of CD161+CD56+NK cells negatively correlated with WBC,IgA,IgM,IgG,ESSRPI and ESSDAI,and positively correlated with complement C4.The proportion of CD161+CD56+NK cells in pSS patients with decayed tooth, fatigue, arthralgia, skin involvement, primary biliary cirrhosis(PBC),interstitial lung disease(ILD), anti-SSA/Ro60 positive, anti-SSB positive and high IgG was lower than that in negative patients. Furthermore, compared with innactive patients,the proportion of CD161+CD56+NK cells decreased obviously in active patients. The area under the curve(AUC)was 0.7375(P=0.0016),the results indicated that CD161+CD56+NK cells had certain diagnostic value for pSS. Conclusion: This study suggested that the proportion of CD56+NK cells and CD161+CD56+NK cells decreased significantly in pSS patients,and the proportion of CD161+CD56+NK cells negatively associated with the clinical features and disease activity of pSS patients. The CD161+CD56+NK cells may present as a potential target for therapy and a biomarker of disease activity in pSS .

The prospect of preventing HIV infection with broadly neutralising monoclonal antibodies (bNAbs) has generated unprecedented enthusiasm in the scientific community and hope among people living with HIV around the world. HIV bNAbs could be a game changer in the prevention of HIV acquisition. Some of these bNAbs are being tested in early phase clinical trials, and the debate is now about the priorities for strategic large-scale efficacy trials. The prevailing view is that only a fixed combination of at least three bNAbs could prevent HIV, regardless of target populations or routes of transmission. We propose an alternative strategy consisting of evaluating the tolerability and efficacy of one or two bNAbs cocktails tailored to different target populations and indications. The rationale for this alternative strategy is based on ethical, pathophysiological and practical facts and is illustrated by the possibility of preventing HIV transmission through breastfeeding in high incidence/prevalence areas such as southern Africa. There is a prospect of eliminating paediatric HIV acquisition through breastfeeding by using single/dual long-acting bNAb regimens.

Tumor immunotherapy has become an important adjuvant therapy after surgery, radiotherapy, and chemotherapy. In recent years, the role of tumor-associated antigen (TAA) in tumor immunotherapy has become increasingly prominent. Cancer-testis antigen (CTA) is a kind of TAA that is highly restricted in a variety of tumors and can induce an immune response. The expression of CTA affects the occurrence, development, and prognosis of ovarian cancer and is closely related to tumor immunity. This review outlines a comprehensive of overview the regulatory mechanism, immunogenicity, clinical expression significance, tumorigenesis, and application prospects of CTA in ovarian cancer, all of which can provide novel insights in the improvement of diagnosis and treatment for ovarian cancer.

Background: In addition to the elimination diet, dietary composition may influence disease severity in patients with Eosinophilic Esophagitis (EoE) through modulation of the immune response. Aim: To explore the immunomodulatory role of nutrition before and during elimination diet in adult EoE patients. Methods: Nutritional intake was assessed in 39 Dutch adult EoE patients participating in the Supplemental Elemental Trial (SET) using 3-day food diaries. In this randomized controlled trial, diagnosed patients received either a four-food elimination diet alone (FFED) or FFED with addition of an amino acid-based formula for six weeks. Multiple linear regression analyses were performed to assess associations between the intake of nutrients and food groups per 1000 kCal and peak eosinophil count/High Power Field (PEC), both at baseline and after six weeks. Results: At baseline, we found a statistically significant negative (thus favorable) relationship between the intake of protein, total fat, phosphorus, zinc, vitamin B12, folate and milk products and PEC (p<0.05), while calcium (p=0.058) and full fat cheese/curd (p=0.056) were borderline (favorably) significant. In contrast, total carbohydrates, prepacked fruit juice and white bread were significantly positively related to PEC (p<0.05) (unfavorable), while ultra-processed meals (p=0.059) were borderline (unfavorably) significant. After dietary intervention, coffee/tea were significantly negatively (favorably) related to PEC, hummus/legumes were significantly positively (unfavorably) related with PEC, while peanuts were borderline significantly positively related (p=0.058). Conclusion: Dietary composition may be related to inflammation in adult EoE patients. High quality and anti-inflammatory diets may be a promising adjuvant therapy in the dietary management of EoE.

Echinococcus multiloculasis is a zoonotic parasitic disease caused by Echinococcus multilocularis, which can cause liver injury, but the mechanism of liver injury is still unclear. Here, Echinococcus multilocularis was injected via the hepatic portal vein to establish a mouse model of infection, and high-throughput RNA sequencing was performed for detecting the expression of miRNAs in the liver of mice infected with 2000 Echinococcus multilocularis after 3 months infection, in order to understand the potential molecular mechanism of liver injury caused by Echinococcus multilocularis infection. Overall, 71 differentially expressed miRNAs were found in liver in comparison with control and a total of 36 mouse miRNAs with |FC|>0.585 were screened out, respectively. In addition, Targetscan (V5.0) and miRanda (v3.3a) software were used to predict differential miRNAs target genes and functional enrichment of target genes. Functional annotation showed that “cytokine-cytokine interaction”, “ positive regulation of cytokine production”, “ inflammatory respose”, “ leukocute activation” were enriched in the liver of Echinococcus multilocularis-infected mice. Moreover, the pathways “human cytomegalovirus infection”, “cysteine and methonine metabolism”, “Notch signaling pathway” and “ferroptosis” were involved in liver disease. Furthermore, 4 miRNAs (mmu-miR-30e-3p, mmu-miR-203-3p, mmu-miR-125b-5p and mmu-miR-30c-2-3p) related to liver injury were screened and verified. This study revealed that the expression profiling of miRNAs in the livers was changed after Echinococcus multilocularis infection, and improved our understanding of the transcriptomic landscape of hepatic echinococcosis in mice.

Cow’s milk protein allergy (CMPA) in Latin America is little studied. We conducted a prospective study in 64 patients with a median age of 3 months, 39/64 (60.94%) were male, 23/64 (35.93%) had malnutrition, 56/64 (87.5%) had familiar atopy, 34/64 (51.56%) were receiving exclusive breastfeeding (EBF). The patients passed a medical evaluation by the specialist and underwent: Prick Test, ImmunoCAP, Fecal Calprotectin (FC) and fecal eosinophil derived neurotoxin (EDN), double-blind placebo control oral food challenges (DBPCFC) and were observed for one year regarding their clinical evolution and acquisition of tolerance. 58/64 (90.63%) had gastrointestinal manifestations, 7/64 (10.94%) had a dermatological manifestation, 2/64 (3.1%) had respiratory manifestations and 2/64 (3.1%) had anaphylaxis. 6/64 (9.38%) had an IgE - mediated CMPA. In patients with Non - IgE Mediated CMPA, fecal calprotectin was found to have a median of 284 mg/dL and an interquartile range (IQR) of 138.5 - 415.5. EDN had a median of 508.5 mg/dL with an IQR of 160.25 - 868. One year after diagnosis, the median FC decreased significantly with p < 0.0001. Malnutrition after one year was reduced to 17.18%. Likewise, 52/64 (81%) acquired tolerance after practicing DBPCFC on them. 33/64 (52%) used nutritional replacement formulas from the time of diagnosis, those who used Nutramigen LGG 15/16 (94%) acquired tolerance after practicing DBPCFC while 12/17 (71%) of those who used other formulas acquired tolerance (p. 0.08). Our findings are a good starting point for future studies that explore the diagnosis, acquisition of CMPA tolerance, and the use of hypoallergenic formulas with the particularities of our region.

Background:Traumatic cartilage injury is an important cause of osteoarthritis (OA) and limb disability, and Toll-like receptors (TLRs) mediated innate immune response has been confirmed to play a crucial role in cartilage injury.In the previous study, we found that the activation of TLR8 molecules in injured articular cartilage was more obvious than other TLRs by establishing an animal model of knee impact injury in rabbits, and the changes of TLR8 molecules could significantly affect the process of articular cartilage injury and repair. Objective: To verify how mir-99a-5p regulates TLR8 receptor mediated innate immune response to treat traumatic cartilage injury. Methods: The impact of a heavy object on the medial condyle of the rabbit’s knee joint caused damage to the medial condylar cartilage. Through pathological and imaging analysis, it was demonstrated whether the establishment of an animal model of traumatic cartilage injury was successful. Establishing a cell model by virus transfection of chondrocytes to demonstrate the role of TLR8 in the innate immune response to impact cartilage injury. Through transcriptome sequencing, potential targets of TLR8, mir-99a-5p, were predicted, and basic experiments were conducted to demonstrate how they interact with innate immune responses to impact cartilage damage. Results:TLR8 is a receptor protein of the immune system, which is widely expressed in immune cells. In our study, we found that TLR8 expression is localized in lysosomes and endosomes.Mir-99a-5p can negatively regulate TLR8 to activate PI3K-AKT molecular pathway and aggravate cartilage damage.Inhibiting TLR8 expresson can effectively reduce the incidence of articular cartilage damage. Conclusion:Based on the results from this study, mir-99a-5p may be an effective molecular marker for predicting traumatic cartilage injury and targeting TLR8 is a novel and promising approach for the prevention or early treatment of cartilage damage.

Abstract Background: The purpose of this meta-analysis was to look at the relationship between hypernatremia and mortality in COVID-19 patients. Methods: We searched the PubMed, Web of science, Embase and Cochrane databases for articles published from the inception of the database until August 27, 2022. Three researchers reviewed the literature, retrieved data, and assessed the quality of the literature, respectively. A meta-analysis was performed using State 17 software to assess the value of the effect of hypernatremia on mortality in patients with new coronavirus pneumonia. Results: A total of 9 publications was finally included in this study, including a total of 11,801 patients with COVID-19, including 1,278 in the hypernatremia group and 10,523 in the normonatremia group. Meta-analysis showed that hypernatremia was associated with mortality in patients with COVID-19 [OR = 4.15, 95% CI (2.95-5.84), P = 0.002, I² = 66.7%] with a sensitivity of 0.36 [0.26, 0.48] and a specificity of 0.88 [ 0.83, 0.91]. The posterior probability of mortality was 42% in patients with COVID-19 hypernatremia and 15% in patients who did not have COVID-19 hypernatremia. Conclusion: According to available data, hypernatremia is associated with death in patients with COVID-19.

Background: Coronavirus disease 2019 (COVID-19) results in several complications and mortality in ICU patients. The effect of enteral nutrition on the survival of COVID-19 patients in the ICU has been investigated in limited instances. The aim of this study is to investigate the association of enteral feeding with biochemical and pathological indices associated with mortality in COVID-19 patients. Methods: This case-control study was conducted on 240 patients with COVID-19 hospitalized in the ICU including 120 eventually dead patients as the cases and 120 discharged patients as the controls. All of the patients received enteral nutrition. Data on general information, anthropometric measurements, and the results of lab tests were collected. Results: The recovered patients received significantly more high protein (60.8% vs. 39.6%, P=0.004) and high volume (61.6% vs. vs. 42.3%, P=0.005) formula compared to the dead patients. Mortality was inversely associated with high volume (OR:0.45 CI95%, P=0.008) and high protein formula (OR:0.42 CI95%, P=0.003). The results remained significant after adjusting for age and sex. Further adjustment for underlying diseases and smoking, BMI, and APACHII did not change the results. Conclusion: The findings of the study showed that there was a significant inverse association between mortality and high volume and high protein formula in COVID-19 patients that warrants further investigation.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for coronavirus disease 2019 (COVID-19), a multifaceted condition. The COVID-19 is associated with various ocular manifestations including conjunctivitis, retinal vein occlusion and optic neuritis. The case of VKH disease associated with SARS-CoV-2 was rare and the specific association is still unclear. Case Presentation In the present study, a 35-year-old female patient with no significant medical history presented with one week of bilateral blurred vision 2 weeks after a clinical course of COVID-19. Both eyes presented with bullous serous retinal detachments. She was diagnosed with incomplete Vogt–Koyanagi–Harada (VKH) disease. Early diagnosis and treatment of VKH disease are essential for the visual prognosis of this aggressive disease. Ocular inflammatory signs and visual acuity improved via corticosteroid therapy in this patient. The case of VKH disease associated with SARS-CoV-2 was rare and the specific association is still unclear. By reviewing similar studies previously reported, we discuss and summarize the potential mechanisms explaining the association between VKH disease and SARS-CoV-2. Conclusion Although the causality remains unclear, ophthalmologists and physicians should be aware of this possible association between VKH disease and COVID-19. SARS-CoV-2 may play a potential immunological triggering role in VKH disease. However, further in-depth researches are necessary to investigate the clinical and epidemiological features, as well as the underlying mechanisms of it. Keywords: Vogt–Koyanagi–Harada disease; SARS-CoV-2; COVID-19; case report

As the SARS-CoV-2 pandemic virus has spread throughout the world, millions of positive cases of COVID-19 have been registered and, even though there are millions of people already vaccinated against SARS-CoV-2, a large part of the global population remains vulnerable to contracting the virus. Given the difficulty of massive sample collection in Puerto Rico and the restrictions to perform the molecular test to detect SARS-CoV-2, this study aims to evaluate the diagnostic accuracy of the TaqPath RT-PCR COVID-19 kit and a LAMP SARS-CoV-2 Laboratory Developed Test in paired nasopharyngeal, saliva, and urine samples. Automated RNA extraction was performed in the KingFisher Flex instrument, whilst PCR quantification of SARS-CoV-2 on the 7500 Fast Dx RT-PCR instrument using the TaqPath RT-PCR COVID-19 molecular test. The PCR data was interpreted by the COVID-19 Interpretive Software from Applied Biosystems and statistically analyzed with Cohen’s kappa coefficient (k). Cohen’s kappa coefficient (k) for paired nasal and saliva samples was found to be 0.52, showing moderate agreement. Nasal and saliva samples displayed concordance and it was determined that saliva samples had a higher viral load. Another objective was to compare the positive or negative result of the RT-PCR with the positive or negative result of LifeGene-Biomarks SARS-CoV-2 Rapid Colorimetric LAMP LDT, which resulted in 90% concordance. Due to this, the use of saliva and LifeGene-Biomarks SARS-CoV-2 Rapid Colorimetric LAMP test is suggested for further evaluation as an alternative to nasal, urine, and RT-PCR tests for the detection of SARS-CoV-2, since it can be easily used in clinics, hospitals, the workplace, and at home, optimizing the surveillance and collection process, which helps mitigate the global public health and socioeconomic damage caused by airborne pandemics.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology. Clinical manifestations include dyspnea and nonproductive cough. Lung transplantation is the only cure, while Pirfenidone and Nintedanib are FDA-approved drugs for slowing disease progression. However, Saracatinib shows greater efficacy. This literature review assesses the safety and efficacy of IPF treatments, focusing on Pirfenidone and Nintedanib, which preserve lung function and reduce fibrosis and inflammation. We also evaluate emerging treatments such as saracatinib, pamrevlumab, pentraxin-2, BI 1015550, ziritaxestat, PBI-4050, bexotegrast, BMS-986020, TD 139, dasatinib, quercetin, and etanercept. Additional research is needed to explore the therapeutic potential and address gaps in IPF management, including exacerbation and associated pulmonary hypertension (PH). Immunosuppressive agents are used to manage IPF exacerbations, while PH is a recognized comorbidity. Clinical trials, PULSAR and SPECTRA, investigate Sotatercept as a potential PH treatment for IPF patients, showing promising results.

To determine distinct phenotype groups in patients with idiopathic inflammatory myopathy (IIM), and to identify the differences of clinical characteristics, laboratory findings, and the long-term outcomes in patients with antisynthetase syndrome (ASS) of different anti-aminoacyl-tRNA synthetase (ARS) antibodies. Methods: We enrolled retrospectively 280 patients with IIM, and the clinical characteristics and laboratory findings were collected. Additionally, multivariate COX regression analysis was performed to identify indicators of poor prognosis in patients with ASS. Results: 119 ASS and 161 non-ASS patients were identified in 280 patients with IIM, the occurrence rates of ILD, RP-ILD, pulmonary symptoms, arthritis, triad and mechanic’s hands with ASS group were more prevalent than non-ASS group ( p＜0.05). Among 119 patients with ASS, the highest incidence of RP-ILD occurred in the PL12 group (36.4%). There was clinical significance of statistical differences in arthritis, myositis, mechanic’s hands, triad, shawl sign, v sign, and Raynaud’s phenomenon among the 4 subgroups ( p＜0.05). At the same time, the individuals in the positive anti-Jo1 antibody group were more likely to exhibit arthritis, myositis, mechanic’s hands, triad and, v sign than the negative anti-Jo1 antibody group in patients with ASS, furthermore, statistically more prevalent ( p＜0.05). According to the multivariate COX regression analysis, mechanic’s hands, ANA, and ILD were independent risk factors for poor prognosis in patients with ASS ( p<0.001, p=0.026, and p<0.001, respectively). V sign was an independent protective factor for good prognosis in patients with ASS ( p=0.026). Conclusions: When clinical characteristics including pulmonary symptoms, arthritis, mechanic’s hands, ANA, along with ILD appear, clinicians should be on the alert for the occurrence of ASS in patients with IIM

Objective B cell activating factor (BAFF) is a key regulator of Primary Sjögren’s Syndrome (pSS), which is characterized by B lymphocyte hyperactivity. BAFF is also known as TNF ligand superfamily member 13B (TNFSF13B). This study aimed to explore whether five single nucleotide polymorphisms (SNPs) of the TNFSF13B gene (rs9514827, rs1041569, rs9514828, rs1224141, and rs12583006) are related to pSS susceptibility. Methods We searched Pubmed, Cochrane, Elsevier, Web of Science, CNKI, CQVIP, and WanFang databases (up to January 2023). In a population with pSS, the odds ratios (ORs) with 95% confidence intervals (CIs) of genotypes and each allele were provided to investigate relationships between the polymorphisms of the BAFF (TNFSF13B) gene and pSS. Results The meta-analysis in question contains three studies. In the group of pSS patients and randomly selected health controls (HCs), there was a statistically significant relationship between rs1041569 and rs12583006 and pSS susceptibility, respectively. In fixed models, there were statistical differences in pSS patients and randomly chosen HCs. Conclusions There were relationships of rs1041569 and rs12583006 in the pSS group and HC group. BAFF(TNFSF13B) genes, particularly rs1041569 and rs12583006, were related to pSS susceptibility in pSS patients.

Background: Maintenance doses for AIT have been recommended for at least 3 years, little data on long-term efficacy is available depending on AIT duration. To show sustained efficacy 10 years after completion of treatment with depigmented-polymerized house dust mite (dpg-pol HDM) allergen extract in adults with asthma and/or rhinoconjunctivitis. Methods: Patients included in a double-blind placebo-controlled AIT study with dpg-pol HDM allergen extract were reviewed at completion of the perennial treatment and 10 years later (10y-FU). Change in symptom and rescue medication score was the primary objective. Visual analogue scale, asthma control test (ACT) and degree of disease control were secondary objectives. A comparative analysis between patients who underwent treatment for < 3 years and ≥ 3 years was performed. Results: Data from 31 patients (mean age 38 years) were available at 10y-FU. All had asthma and 29 had rhinoconjunctivitis at baseline. Twenty-three patients were treated ≥ 3y and 8 for < 3y. Seventeen (55%) patients were asymptomatic at completion AIT completion, with significant differences for nasal, conjunctival and bronchial symptoms (p<0.0001) compared to baseline only in patients treated ≥3y. Nine (52.9%) patients remained completely asymptomatic at 10yFU , all were treated for ≥ 3 years. Moreover, significant reduction in the number of patients with rhinitis (p=0.0117), conjunctivitis (p<0.0001) and bronchial (p=0.0005) symptoms was observed at 10y-FU compared to baseline only in the ≥3y treated. Ten (32.3%) patients didn´t require any rescue medication at 10y-FU, all had been treated for ≥ 3y. ACT at 10y-FU showed a good control of asthma (median 23.5; 95% IC[22.0, 25.0]). No significant differences were observed between VAS at end of treatment compared to VAS at 10y-FU. Conclusions: Sustained clinical efficacy is achieved 10 years after completion of depigmented-polymerized HDM, however these findings were observed only if patients are treated for at least 3 years.

ABSTRACT The current absence of gold-standard or all-aspect favorable therapies for COVID-19 renders a focus on multipotential drugs proposed to prevent or treat this infection or ameliorate its signs and symptoms vitally important. The present well-designed randomized controlled trial sought to evaluate the efficacy and safety of N-acetylcysteine as adjuvant therapy in hospitalized Iranian patients with COVID-19. Four different diets in 60 patients include; Kaletra (lopinavir/ritonavir) + hydroxychloroquine with/without N-acetylcysteine (600 mg TDS) and atazanavir/ritonavir + hydroxychloroquine with/without N-acetylcysteine (600 mg TDS), were administered in the study. At the end of the study, a further decrease in C-reactive protein was observed in groups with N-acetylcysteine (P =0.008), and no death occurred in the atazanavir/ritonavir + hydroxychloroquine + N-acetylcysteine group, showing that the combination of these drugs may reduce mortality. A significant rise in O2 saturation was observed in atazanavir/ritonavir+hydroxychloroquine+N-acetylcysteine group (P <0.05). Accordingly, oral or intravenous N-acetylcysteine, may enhance O2 saturation, blunt the inflammation trend (by reducing C-reactive protein), and reduce mortality in hospitalized patients with COVID-19. The N-acetylcysteine could be more effective as prophylactic or adjuvant therapy in stable and non-severe cases of COVID-19 with a particularly positive role in the augmentation of O2 saturation and faster reduction of the CRP level and inflammation.

Background: Type 2 diabetes mellitus (T2DM), which has a high incidence and several harmful consequences, poses a severe danger to human health. More research is being done on ferroptosis’ function in T2DM. This study uses a bioinformatics technique to look for new diagnostic T2DM biomarkers associated with ferroptosis. Methods: In order to identify ferroptosis-related genes (DEGs) that are differently expressed between T2DM patients and healthy individuals, we first obtained T2DM sequencing data and ferroptosis-related genes (FRGs) from the Gene Expression Omnibus (GEO) database and FerrDb database. Then, drug-gene interaction networks and ceRNA networks linked to the marker genes were built after marker genes were filtered by two machine learning algorithms (LASSO and SVM-RFE algorithms). Finally, to confirm the expression of marker genes, the GSE76895 dataset was utilized. The protein expression of some marker genes between T2DM and non-diabetic tissues was also examined by Western Blotting, Immunohistochemistry (IHC) and Immunofluorescence (IF), respectively. Results: We obtained 58 DEGs associated with ferroptosis. GO and KEGG enrichment analysis showed that these DGEs were significantly enriched in hypoxia and ferroptosis. Subsequently, eight marker genes (SCD, CD44, HIF1A, BCAT2, MTF1, HILPDA, NR1D2 and MYCN) were screened by LASSO and SVM- RFE machine learning algorithms, and a model was constructed based on these eight genes. These newly discovered marker genes may be linked to alterations in the immune microenvironment in T2DM patients. In addition, based on these 8 genes, we obtained 48 drugs and a complex ceRNA network map. Finally, Western Blotting, IHC and IF results of clinical samples further confirmed the results of public databases. Conclusions: The diagnosis and etiology of T2DM can be greatly aided by eight ferroptosis-related genes, opening up novel therapeutic avenues.
