Article Abstract
Current studies on the immune microenvironment of colorectal cancer (CRC) were mostly limited to the tissue level, lacking relevant studies in the peripheral blood, and failed to describe its alterations in the whole process of adenocarcinoma formation, especially of adenoma carcinogenesis. Here, we constructed a large-scale population cohort and used the CyTOF to explore the changes of various immune cell subsets in peripheral blood of CRC. We found monocytes and basophils cells were significantly higher in adenocarcinoma patients. Compared with early-stage CRC, effector CD4T cells and naive B cells were higher in patients with lymph node metastasis, whereas the basophils were lower. We also performed random forest algorithm and found monocytes play the key role in carcinogenesis. Our study draws a peripheral blood immune cell landscape of the occurrence and development of CRC at the single-cell level and provides a reference for other researchers.

Adoptive transfer of third-party donor CMV-specific T cells for refractory cytomegalovirus infection following umbilical cord blood transplantation.

Refractory cytomegalovirus (CMV) infection is a severe complication following umbilical cord blood transplantation (UCBT). Antiviral agents, the standard first-line therapy, are limited by toxicity and resistance without robust T-cell immunity. We evaluated third-party donor (TPD)-derived CMV-specific T cells (CMVSTs) as a treatment option.

Background: Fish are the largest group of vertebrates. Studying the characteristics, functions, and interactions of different fish cells is important for understanding their roles in disease and evolution. However, most single cell RNA-seq studies in fish are restricted to a few specific organs, leaving a comprehensive cell landscape that aims to characterize the heterogeneity and connections among body-wide organs largely unexplored.

Oncometabolites are aberrant metabolic byproducts that arise from mutations in enzymes of the tricarboxylic acid (TCA) cycle or related metabolic pathways and play central roles in tumor progression and immune evasion. Among these, 2-hydroxyglutarate (2-HG), succinate, and fumarate are the most well-characterized, acting as competitive inhibitors of α-ketoglutarate-dependent dioxygenases to alter DNA and histone methylation, cellular differentiation, and hypoxia signaling. More recently, itaconate, an immunometabolite predominantly produced by activated macrophages, has been recognized for its dual roles in modulating inflammation and tumor immunity.

As the field of gene therapy advances and as the importance of sex as a biological variable in shaping viral immune responses is recognized, the impact of sex on adeno-associated virus (AAV) vectors mediated gene therapies remain largely unexplored. Here we review current understanding of the immune response against AAV gene therapy as well as the knowledge of sex differences observed in viral responses. We discuss sex differences in innate immune mechanisms such as Toll-like receptor recognition and complement activation, as well as the functional responses of key immune cells such as dendritic cells, macrophages, and T/B cells that are involved in AAV immunogenicity.

Patients with primary plasma cell leukemia (pPCL), particularly those with extramedullary disease (EMD), face a poor prognosis even with chimeric antigen receptor (CAR)-T cell therapy. This case report describes a patient with relapsed/refractory pPCL and life-threatening malignant pleural effusion (PE) treated with intrapleural CAR-T cells targeting B-cell maturation antigens. CAR-T cell expansion within the PE was observed, along with a rapid reduction in leukemia cell count and PE volume.
