Group 3 - Immunity - Coggle Diagram

- - - - Plasma Cells: produce/release antibody in presence of antigen
      - B-memory Cells: retain memory of recognized antigen and clone itself in the presence of antigen
    - - T-helper cells: help function of B-cells
      - T-suppressor cells: turn off B-cells
      - T-memory cells: recognize/retain memory of antigens
      - T-cytotoxic cells: attack virally infected or tumor cells
- - - - Occurs in Type I, Type II, and Type III hypersensitivity reactions
        
        Individuals with deficiency in humoral immunity are more likely to develop bacterial infections
    - - B cells develop into plasma cells
        
        Plasma cells produce antibodies to protect the body against pathogens
        
        Examples of conditions in which humoral immunity is impaired are:
        Sjögren syndrome, SLE, Severe combined immunodeficiency
  - - - T lymphocytes also regulate humoral immunity
        
        Examples of conditions in which cellular immunity is impaired are: HIV/AIDS, Herpes Zoster Infection, Severe combined immodeficiency
    - - Occurs in Type IV hypersensitivity reactions
        
        Individuals with deficiency in cellular immunity are more likely to develop viral infections, fungal infections, and infections like TB (caused by intracellular bacteria)
