An efficient antiviral cytotoxic T lymphocyte (CTL) response to HTLV-1 infection maintains a low proviral load (PVL), reducing the risk of HAM/TSP. Host genotype , particularly of HLA class I, is a major determinant of CTL efficiency, and the influence of specific HLA class I alleles on HTLV-1 immunity is well documented. We recently showed that killer(More)
NK cells use NK cell receptors to be able to recognize and eliminate infected, transformed, and allogeneic cells. Human NK cells are prevented from killing autologous healthy cells by virtue of inhibitory NKRs, primarily killer cell Ig-like receptors (KIR) that bind "self" HLA class I molecules. Individual NK cells stably express a selected set of KIR, but(More)
BACKGROUND Occurring frequently after solid organ and hematopoietic stem cell transplantation, cytomegalovirus (CMV) replication remains a relevant cause of mortality and morbidity in affected patients. Despite these adverse effects, an increased alloreactivity of natural killer (NK) cells after CMV infection has been assumed, but the underlying(More)
