The co-receptor signaling model of HIV-1 pathogenesis in peripheral CD4 T cells.

abstract：:Traditionally, NK cells belong to the innate immune system and eliminate virus-infected cells through their germline-encoded receptors. However, NK cells were recently reported to possess memory-like functions that were predominantly provided by hepatic NK cells. Memory properties were mainly documented in contact hyp...
