T H B Activating Cell Antibodies Activated  Cells

Original 1. antigen-presenting phagocytes migrate to lymph nodes, activating TH cells 
2. TH cells release cytokines, activating the B cell which produces antibodies specific to the antigen 
3. activated B cell divides and differentiates to form plasma cells that mass produce the antibodies 
4. antibodies target the antigen, enhancing immune system's capacity to recognize/destroy the pathogen
5. a portion of activated B and TH cells develop into memory cells for long-lasting immunity
