Impaired Memory B Cell Generation C4025672

Published: July 22, 2026Updated: August 20, 2026

An immune deficiency where B cells fail to develop properly into memory cells, weakening the body's ability to remember past infections and respond to new threats. It can cause recurrent infections, particularly of the respiratory tract. Management includes infection prevention and sometimes immunoglobulin therapy.
