CD8+ T cell memory is sustained in mice by hepatic stellate cells
HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.
