Ng et al. have identified NKG7 as a regulator of inflammation in response to diverse immunological challenges. While NKG7 was required for the degranulation of cytotoxic cells, additional defects including reduced expansion and trafficking of CD8 T cells, and altered antigen presentation, were noted in NKG7-deficient mice. The precise mechanism by which NKG7 mediates its effects has not been resolved but may involve regulation of endosomal vesicle trafficking.

Spinal cord injury (SCI) increasingly affects aged individuals, where functional impairment and mortality are highest. However, the aging-dependent mechanisms underpinning tissue damage remain elusive. Here, we find that natural killer-like T (NKLT) cells seed the intact aged human and murine spinal cord and multiply further after injury.

Background And Aims: Refractory celiac disease type II (RCDII) is characterized by a clonally expanded aberrant cell population in the small intestine. The role of other tissue-resident immune subsets in RCDII is unknown. Here, we characterized CD8 and CD4 T cells in RCDII duodenum at the single-cell level and .

Lack of biopsies after treatment, especially in solid tumors, restricts the understanding of chimeric antigen receptor (CAR)-T cells -related characteristic in vivo, thus hindering the development of strategies to improve CAR-T cells efficacy. Here, we applied nineteen individual single-cell RNA sequencing (scRNA-seq) data from clinical samples of digestive cancers to explore the characteristics of tumor-infiltrating T cells (TILs) to identify effective targets which might be benefit for enhancing the function of CAR-T cells. The data showed that natural killer cell granule protein 7 (NKG7) was overexpressed in TILs and positively associated with anti-PD1 or anti-CTLA4 therapy in digestive cancers.

As nonhuman primates are immunologically the closest model to humans, a comprehensive understanding of T-cell development in these species is crucial. However, the differentiation pathways in which thymocytes participate, along with their heterogeneity, remain poorly characterized. Using single-cell RNA sequencing, we thoroughly profiled the development of various T-cell lineages in the juvenile cynomolgus monkey thymus, identifying and characterizing 12 distinct thymic cell states or types.

In this study, we investigated the molecular differences between patients with typical obstetric antiphospholipid syndrome (OAPS) and patients with non-criteria obstetric antiphospholipid syndrome (NC-OAPS) patients through transcriptome sequencing of peripheral blood samples from ten OAPS patients and ten NC-OAPS patients. Differentially expressed genes (DEGs) were identified, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, protein-protein interaction (PPI) analysis, and competitive endogenous RNA (ceRNA) network construction to identify hub genes. Verification was performed via Quantitative Real-time PCR (qPCR) in OAPS (n=9) and NC-OAPS (n=12) samples.
