Primary antibody deficiencies represent the most frequent genetic diseases of the immune system and the first to be recognized along immunology history. The antibodies were recognized as part of the humoral immune system long ago, and after immunoglobulin discovery, the first antibody immunodeficiency were recognized and named as "agammaglobulinemia", followed by the common variable immunoendeficiency and the hyper-IgM syndrome. ⋯ Then, this manuscript pretends to review the relevant findings in the history of immunology, focused on the B cells and the connection with the description of representative clinical entities of primary antibody deficiencies. The aim of this manuscript is to show to the reader that the generation of scientific knowledge has a direct application in the understanding of the molecular mechanisms that are affected in these diseases.
