Article Abstract

Activated CD8 T cells directly kill target cells. Therefore, the regulation of their function is central to avoiding immunopathology. Mechanisms that curb effector functions in CD4 and CD8 T cells are mostly shared, yet important differences occur. Here, we focus on the control of CD8 T cell activity and discuss the importance of a poorly understood aspect of tolerance that directly impairs engagement of target cells: the downregulation of CD8. We contextualize this process and propose that it represents a key element during CD8 T cell modulation.

Objective: To evaluate the effectiveness of intravenous laser irradiation of blood in reducing viral load and increasing LT-CD4+ and LT-CD8+ in people living with HIV/AIDS.

Method: Randomized, controlled, parallel, single-blind clinical trial. Twenty-eight participants were allocated to the intervention (ILIB n = 15) and control (CTRL n = 13) groups.

Background: Comorbidities and genetic correlations between gastrointestinal tract diseases and psychiatric disorders have been widely reported, but the underlying intrinsic link between Alzheimer's disease (AD) and inflammatory bowel disease (IBD) is not adequately understood.

Methods: To identify pathogenic cell types of AD and IBD and explore their shared genetic architecture, we developed Pathogenic Cell types and shared Genetic Loci (PCGL) framework, which studied AD and IBD and its two subtypes of ulcerative colitis (UC) and Crohn's disease (CD).

Results: We found that monocytes and CD8 T cells were the enriched pathogenic cell types of AD and IBDs, respectively.

Introduction: Endothelial cells play a critical role in tumor-associated vasculature formation and immune modulation, and dysregulation of transcription factors (TFs) such as Meox1 has been associated with various cancers, including non-small cell lung cancer (NSCLC). Meox1 has been implicated in promoting both tumor-promoting and immune-suppressing functions.

Methods: In this study, to systematically map TF dynamics across cancer and immune cells, we performed scRNA-seq on tumor tissues and used the SCENIC framework for regulon analysis, revealing cell-type-specific gene regulatory networks.

State Key Laboratory of Respiratory Disease, National Clinical Research Center for Respiratory Disease, Guangzhou Institute of Respiratory Health, First Affiliated Hospital of Guangzhou Medical University, Guangzhou, People's Republic of China.

Purpose: Nocardiosis is an opportunistic infection in lung transplant recipients but is often misdiagnosed or overlooked. This study aimed to identify risk factors and develop an effective predictive model for nocardiosis in this population.

Patients And Methods: This single-center retrospective study analyzed 679 lung transplant recipients from January 1, 2015, to July 9, 2024.
