WebMemory B cells live longer than their naïve precursors (9), raising the question of whether memory B cells still rely on BLyS-BR3 signaling. Furthermore, LLPC express high levels of BCMA (10), which binds either BLyS or APRIL, raising the possibility that either cytokine might afford survival. Similarly, B lymphocytes (B cells), which are part of the normal immune response, are also responsible for the over-aggressive response seen in autoimmune diseases like systemic lupus erythematosus. B cells develop in the bone marrow and continue to mature peripherally in secondary lymphoid organs and in the gut. When autoimmune B cells attack the body's own tissues, they are normally destroye…
