Although the functions of vanins have been widely examined in myeloid cells, their expression and functions have not been clarified in T lymphocytes. This study aimed to elucidate the significance of Vanin-2 (VNN2) on human peripheral blood T lymphocytes and study its expression in systemic lupus erythematosus (SLE). The differential expression of Vanins was analyzed by bioinformatics. VNN2 expressions in peripheral blood T-cell subsets were analyzed by single-cell RNA sequencing data and flow cytometry. Changes of VNN2 expression before and after T-cell activation were further clarified by western blot. The function of VNN2+ cells was studied by granzyme B (GZMB) and perforin detection. Changes in VNN2+ proportions in T-cell subsets of patients with SLE were further analyzed. In the present study, only VNN2 among vanins showed distinguishable expression in T cells. VNN2+ percentages were higher in CD8+ T cells those in CD4+ T cells. VNN2+ T cells were with a higher memory T-cell composition. VNN2 expression was significantly increased after T-cell stimulation. VNN2+ T cells had higher levels of GZMB and perforin secretion than VNN2\u2212 T cells. Clinically, VNN2+ percentages in T cells of patients with SLE were upregulated. Together, these data suggested that VNN2 is expressed in peripheral blood T cells characterized more GZMB and perforin secretion, and increased VNN2+ T cells in patients with SLE could reflect altered T-cell functions in vivo.<\/jats:p>","DOI":"10.1093\/jleuko\/qiae145","type":"journal-article","created":{"date-parts":[[2024,6,25]],"date-time":"2024-06-25T05:52:05Z","timestamp":1719294725000},"page":"1469-1478","source":"Crossref","is-referenced-by-count":6,"title":["Vanin-2
