Percentage of CD20⁺CD27⁺CD43^lo–int cells expressing either CD5, IgM or CD21^lo in CVID patients compared to healthy controls. Whole blood was stained as stated in the Methods. Cells were gated as described in Fig. 2. Percentage of CD20⁺CD27⁺CD43^lo–int cells in common variable immunodeficiency (CVID) patients (n = 16) and healthy controls (n = 33) expressing either CD5 (a), immunoglobulin (Ig)M (b) or CD21^lo (c). (d) Percentage of CD20⁺CD27⁺CD43^lo–int cells expressing CD21^lo in CVID patients stratified into respective EUROclass classification groups.
