TACI Expression and Signaling in Chronic Lymphocytic Leukemia

Figure 1

TACI along with CD27 and IgD expression on B cells established by flow cytometry in a healthy individual and 2 patients with CLL. TACI is expressed only on normal switched and nonswitched memory B cells (CD27⁺IgD⁻ and CD27⁺IgD⁺, resp.) (a). CLL cells were CD27⁺ and the majority of them also IgD⁺, with high (b) and low (c) TACI expression.
