What is an attack on the B lymphocytes?

An attack on B lymphocytes refers to a situation where these crucial immune cells are targeted and compromised, often by pathogens, autoimmune diseases, or certain therapies. B lymphocytes are responsible for producing antibodies that help protect the body against infections. When they are attacked, it can lead to impaired immune responses, making the body more susceptible to infections and diseases. Conditions like systemic lupus erythematosus or certain types of leukemia can involve such attacks on B cells.
