  • Types of Activated T-cells
    • Activation (antigen-binding) produces 3 types of mature T cells
      • Helper T cells 
        • “Help” the immune response by activating other cells and coordinating a response
      • Cytotoxic/killer T cells 
        • Directly kill pathogens/infected cells by releasing perforin, a protein which punctures the antigen-carrying cell
      • Memory T cells
        • Store information (memory) about specific pathogen to prepare for secondary response 
      • T regulatory cells: help reduce autoimmune diseases by distinguishing b/w self and nonself molecules
