What are the stages of lymphocyte response to infections?

Naive —> effector lymphocytes—> plasma cells—> memory cells Naïve lymphocytes – express receptors for antigens, but cannot eliminate antigens. If not activated by antigen survive weeks – months, and die by apoptosis. Effector lymphocytes B cells -> plasma cells that produce antibodies Effector T cells -> kill infected cells Memory cells survive long-time (years)
