Here we present the characterization of a new antigen called CB02 which is present on B cells and on a subset of CD16+ large granular lymphocytes. The pattern of reactivity of this molecule on normal cells, B cell lines, leukemic cells and tissue sections suggests that the CB02 molecule is expressed by B cells before isotype switch and is lost during terminal differentiation. Furthermore, the CB02+ population encompassed natural killer (NK) cells exerting significant cytotoxic activity: in fact, peripheral blood lymphocytes depleted of the CB02+ subset display a marked reduction in NK activity.

Abstract
Here we present the characterization of a new antigen called CB02 which is present on B cells and on a subset of CD16+ large granular lymphocytes. The pattern of reactivity of this molecule on normal cells, B cell lines, leukemic cells and tissue sections suggests that the CB02 molecule is expressed by B cells before isotype switch and is lost during terminal differentiation. Furthermore, the CB02+ population encompassed natural killer (NK) cells exerting significant cytotoxic activity: in fact, peripheral blood lymphocytes depleted of the CB02+ subset display a marked reduction in NK activity.File in questo prodotto:
