The major histocompatibility complex class I (MHC-I) transactivator, nucleotide binding oligomerization domain-like receptor family caspase recruitment domain containing 5 (NLRC5), serves as a target for immune evasion in many cancers, including endometrial cancer (EC). An inhibition of autophagy can contribute to immunotherapy by assisting the MHC-I-mediated antigen presentation in cancer. However, the underlying mechanism for autophagy-regulated MHC-I in EC remains unclear. In this study, we found that autophagy was upregulated in EC tissues when compared to that in normal endometrial tissues. MHC I and NLRC5 expressions were lower in EC endometrium than in normal endometrium. Autophagy inhibited the MHC-I genes expression in vitro. Furthermore, a negative correlation was found between NLRC5 and LC3 levels, and LC3 interacted with NLRC5 to inhibit NLRC5-mediated MHC-I antigen presentation pathway in vitro and in vivo. Thus, our findings demonstrated that an upregulation of LC3 in EC patients may contribute to tumor immune escape by restricting the NLRC5-mediated MHC-I antigen presentation pathway, signifying inhibiting LC3 and promoting NLRC5 may be a promising immunotherapy strategy in the management of EC.

Purpose: To investigate the follicle microenvironments of women with premature ovarian insufficiency (POI), with normal ovarian reserve function, and who are older (age >40 years) and to identify potential therapeutic targets.
Patients And Methods: In total, 9 women who underwent in vitro fertilization(IVF) or intracytoplasmic sperm injection(ICSI) were included in this study. The first punctured follicle of each patient was used.

Background: Cardiac macrophages are a heterogeneous population with high plasticity and adaptability, and their mechanisms in heart failure (HF) remain poorly elucidated.
Methods: We used single-cell and bulk RNA sequencing data to reveal the heterogeneity of non-cardiomyocytes and assess the immunoreactivity of each subpopulation. Additionally, we employed four integrated machine learning algorithms to identify macrophage-related genes with diagnostic value, and in vivo validation was performed.

Intrahepatic cholangiocarcinoma (ICC) tumor cells and their interactions with the immune microenvironment, particularly at the leading-edge area, have been underexplored. This study employs single-cell RNA sequencing (scRNA-seq) and spatial transcriptome (ST) analysis on samples from the tumor core, adjacent non-tumorous tissue, and the leading-edge area of nine ICC patients. These findings indicate that tumor cells at the leading-edge area demonstrate enhanced proliferation and are tightly associated with the stroma, including endothelial cells and POSTN+ FAP+ fibroblasts.

The hypoxic microenvironment is an essential feature of solid tumors. 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.

Accumulation of senescent neurons in the dorsal root ganglion (DRG) is an important tissue phenotype that causes age-related degeneration of peripheral sensory nerves. Senescent neurons are neurons with arrested cell cycle that have undergone cellular senescence but remain in the tissue and play various biological roles. To understand the accumulation of senescent neurons in the DRG during aging, we aimed to elucidate the mechanism that induces cellular senescence in DRG neurons and the role of senescent DRG neurons.
