CD4+ T cells of 57 patients with B cell chronic lymphocytic leukaemia (CLL) were analysed for expression of CD45RA and CD29. The majority of CLL patients (33 cases) showed a novel coexpression of these markers on a significant proportion of CD4+ T cells; however, analysis of a single blood sample revealed no apparent prognostic value associated with the markers. Expression of CD45RA and CD29 correlated with parameters of immune function consistent with the known attributes of these markers.
