Abstract:Introduction: An expansion of CD4+ T cells expressing perforin (PF) has recently been described in B-CLL and we have previously demonstrated anti-cytomegalovirus (CMV) reactivity within this population (Walton et al; 2004; Blood [ASH annual meeting abstracts] 104:4787). Here we further characterise the anti-CMV response of CD4+PF+ T cells in B-CLL and investigate the role of CMV in CD4+PF+ T cell expansion.
Methods: Peripheral blood mononuclear cells (PBMC’s) from 24 untreated B-CLL patients (17… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
