Gammadelta T cells are a multifaceted group of cells which have both innate and adaptive characteristics and functions. Although they are most commonly known for their response to mycobacterium and their locations at mucosal sites, their roles in autoimmunity are still unclear. gammadelta T cells have been seen in the CSF and lesions of Multiple Sclerosis patients and although their function is not entirely understood, it is clear these cells may have roles in regulating autoimmune inflammation in the CNS. Recent studies have focused on the role of gammadelta T cells in MS and EAE as both pathogenic and protective, their functions within the CNS, the types of subsets and a possible role in Th17 inflammation. In this review we will examine the data acquired from both human patients and the murine models of MS, experimental autoimmune encephalomyelitis (EAE), in order to gain a clear picture of how gammadelta T cells influence pathogenesis of EAE and MS.

Background: Multiple studies have demonstrated that the abundance and functionality of γδ T cells are favorable prognostic indicators for prolonged survival in cancer patients. However, the association between the immunophenotype of circulating γδ T cells and the therapeutic response in NSCLC patients undergoing chemotherapy or targeted therapy remains unclear.
Methods: Patients with EGFR wild-type (EGFR-WT) or mutant (EGFR-Mut) non-small cell lung cancer (NSCLC), diagnosed between January 2020 and January 2024, were included in this study.
γδ T cells producing either interleukin-17A (γδ cells) or interferon-γ (γδ cells) are generated in the mouse thymus, but the molecular regulators of their peripheral functions are not fully characterized. Here we established an Il17a-GFP:Ifng-YFP double-reporter mouse strain to analyze at unprecedented depth the transcriptomes of pure γδ cell versus γδ cell populations from peripheral lymph nodes. Within a very high fraction of differentially expressed genes, we identify a panel of 20 new signature genes in steady-state γδ cells versus γδ cells, which we further validate in models of experimental autoimmune encephalomyelitis and cerebral malaria, respectively.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Previous studies have established that γδ T cells play a significant role in liver fibrosis. However, their specific functions and mechanisms in fibrotic liver tissue remain unclear. Using online microarray expression profiles, we observed that USF3 was upregulated in patients with liver fibrosis and was associated with immune cells.
