Aim: To study the effects of CD74 gene on IFN-γR expression in myasthenia gravis thymic epithelial cell(TEC).
Methods: PCMV-CD74 transiently transfect to primary cultured TEC mediated with lipofectamine, the result of transfection and some autoimmune related genes such as IFN-γR were detected by real-time RT-PCR.
Results: Real-time quantitative RT-PCR results show that the mRNA expression level of IL-4R, IL-32, IFN-γR, ECGF1, HLA-A, HLA-DR increased significantly, with the high express ion of CD74 gene in thymic epithelial cells.
Conclusion: CD74 gene over-expression in TEC can increase IFN-γR mRNA expression.

Background: Microsatellite instability-high (MSI-H) metastatic colorectal cancer (CRC) patients are the dominant population in immune checkpoint blockade treatments, while more than half of them could not benefit from single-agent immunotherapy. We tried to identify the biomarker of MSI-H CRC and explore its role and mechanism in anti-PD-1 treatments. Tumor-specific MHC-II was linked to a better response to anti-PD-1 in MSI-H CRC and CD74 promoted assembly and transport of HLA-DR dimers.

Antigen presentation plays a critical role in the pathogenesis of immune-mediated disorders. This study aimed to investigate the effects of IFN-γ and a cytokine mix (5MIX: IL-1α, IL-17A, IL-22, OsM, and TNF-α) on the antigen-presenting capabilities of keratinocytes, with a specific focus on immune-mediated dermatological conditions such as psoriasis (Ps). To achieve this, keratinocytes were treated with IFN-γ and 5MIX, and their impact on the expression of key antigen-presentation molecules, HLA-DRα and CD74, was assessed.

Introduction: The transcriptomic characteristics of + non-small cell lung cancer (NSCLC) represent a crucial aspect of its tumor biology. These features provide valuable insights into key dysregulated pathways, potentially leading to the discovery of novel targetable alterations or biomarkers.
Methods: From The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases, all available + (n = 10), + (n = 5) and + (n = 5) NSCLC tumor and + cell line (n = 7) RNA-sequencing files were collected.

PEDV is a highly contagious enteric pathogen that can cause severe diarrhea and death in neonatal pigs. Despite extensive research, the molecular mechanisms of host's response to PEDV infection remain unclear. In this study, differentially expressed genes (DEGs), time-specific coexpression modules, and key regulatory genes associated with PEDV infection were identified.

Background: Hepatocellular carcinoma (HCC) is a highly heterogeneous tumor, and the development of accurate predictive models for prognosis and drug sensitivity remains challenging.
Methods: We integrated laboratory data and public cohorts to conduct a multi-omics analysis of HCC, which included bulk RNA sequencing, proteomic analysis, single-cell RNA sequencing (scRNA-seq), spatial transcriptomics sequencing (ST-seq), and genome sequencing. We constructed a tumor purity (TP) and tumor microenvironment (TME) prognostic risk model.
