In this study, we conducted a comprehensive investigation on the peripheral blood mononuclear cells (PBMCs) profile of an APMPPE patient using single-cell RNA sequencing. Our analysis revealed striking transcriptional alterations in monocytes within the PBMCs, identifying five distinct subpopulations: S100A12, CD16, pro-inflammatory, megakaryocyte-like, and NK-like monocyte subsets. Employing pseudotime inference, we observed a shift in APMPPE monocytes towards differentiation into inflammation-associated pro-inflammatory monocytes and a CD16 monocyte trajectory. Furthermore, we identified IFITM3 as a key player in the immune response driving the pathogenesis of APMPPE. Notably, two disease-relevant subgroups of monocytes, pro-inflammatory and CD16 monocytes, were implicated in APMPPE. CD16 monocytes, in particular, were involved in melanogenesis, suggesting that the abnormal expression of melanin in monocytes might result from autoimmune responses against pigment-enriched RPE cells.

Autophagy has been controversial in its role in immune regulation. This project aims to elucidate the impact of autophagy in pancreatic cancer (PC) under specific conditions (hypoxia) on CD8+ T cells and the regulatory mechanisms behind it.The levels of HIF1α and autophagy were analyzed by western blot (WB) and immunofluorescence (IF). The effects of HIF1α on cell autophagy were assessed in normoxic or hypoxic treatments using KC7F2 (HIF-1 channel inhibitor) or chloroquine (autophagy inhibitor). CD8+ T cells were co-cultured with PC cells to assess the cytotoxicity using lactate dehydrogenase (LDH) and Hoechst/PI staining. The content of cytokines and the activation level of CD8+ T cells were measured by enzyme-linked immunosorbent assay (ELISA) and flow cytometry. MHC-I expression in PC cells (membranes) was analyzed using quantitative reverse transcription polymerase chain reaction (qRT-PCR), WB, IF, and flow cytometry. Humanized immune-reconstituted mice were applied to investigate the impact of HIF1α-induced autophagy on in vivo immunity.When cells were in hypoxia, the levels of HIF1α and autophagy were higher compared to normoxic conditions. Treatment with KC7F2 resulted in similar levels of HIF1α and autophagy as those in normoxic state. Chloroquine treatment reversed the autophagy level to the normoxic state. The autophagy level of PC cells transfected with oe-HIF1α was increased, with reduced MHC-I expression on cells (membranes), which impaired the cytotoxicity of CD8+ T cells, and thus decreasing the probability of recognition and attack by CD8+ T cells when co-cultured with them. In mice, overexpression of HIF1α hindered the immune suppressive function of CD8+ T cells and facilitated the immune escape of PC by reducing antigen presentation of MHC-I.Under hypoxia, HIF1α-induced autophagy reduces the cytotoxicity of CD8+ T cells by repressing MHC-I expression.","PeriodicalId":12691,"journal":{"name":"Genes and immunity","volume":"26 1","pages":"45-53"},"PeriodicalIF":5.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142882007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, RT-qPCR and western blotting were employed to detect the expression level of GXYLT2. RNA interference assays were used to knock down GXYLT2. CCK-8, wound healing assays, clone formation assays, and Transwell assays were utilized to investigate the function of GXYLT2. Bioinformatics analysis was used to explore the tumor microenvironment and potential biological mechanisms. We found that the expression level of GXYLT2 in ccRCC was higher than that in adjacent normal renal tissues. Patients with high GXYLT2 expression have worse clinical outcomes. Knockdown of GXYLT2 inhibits the proliferation, invasion, migration, and clone formation ability of ccRCC cells. Enrichment analysis uncovered that GXYLT2 participates in Wnt, cell cycle, and actin cytoskeleton regulation signaling pathways. After receiving anti-PD-1 therapy, patients with high GXYLT2 expression had longer progression-free survival compared with those with low GXYLT2 expression.
