Cytolysis function
WebThe cytolysis function of human NK cells is mediated partially by CD160 molecule. The decrease of CD160 expression on NK cells from patients with various hematological malignancies implies that down-regulation of CD160 expression may be a novel mechanism of tumor immune escape. WebThe function of the unusual DNA fragmentation induced by CTL remains to be elucidated. The major recognized function of CTL is in halting virus infections. Earlier, we proposed that CTL might halt virus infections prelytically, by fragmenting viral and cellular nucleic acids, and that in this case, cytolysis per se might be a less important ...
