Cоmmоn vаriаble immunоdeficiency (CVID) is а rather mild immunodeficiency disease that generally appears in young adults, with a peak onset between ages 20–30. CVID patients suffer from recurrent bacterial infections of the respiratory tract, the ears, and the gastrointestinal tract. Analysis of their peripheral blood cells shows normal numbers and subsets of T cells. B cell data from peripheral blood (PBL) are shown in the Figure below. Based on these data, what immune molecule that recognizes bacteria is most likely reduced in patients with CVID? Explain your reasoning.
