Ans) Type IV hypersensitivity is a cell-mediated immune reaction. In other words, it does not involve the participation of antibodies but is due primarily to the interaction of T cells with antigens. The T cells involved in type IV reactions are memory cells derived from prior stimulation by the same antigen.
- Various autoimmune disorders as well as allergies fall under the umbrella of hypersensitivity reactions, the difference being that allergies are immune reactions to exogenous substances (antigens or allergens), whereas autoimmune diseases arise from an abnormal immune response to endogenous substances (autoantigens).
discuss the difference between tissue specific hypersensitivity and cell mediated hypersensitivity reactions
Which of the following types of hypersensitivity reactions involves antibody-mediated responses? A) Type I hypersensitivity B) Type ll hypersensitivity C) Type Ill hypersensitivity D) Type IV hypersensitivity E) Hypersensitivity types I and Il only F) Hypersensitivity types I, II, and IlII only G) All Hypersensitivity types (I, I1, IlI and Iv)
Discuss the major differences between humoral and cell-mediated immunity, including cell types involved and the end result of the immune process. Why is it essential to have both a humoral as well as a cell-mediated immune response in order to have a fully competent immune system? Please cite outside sources in APA format if used

humoral immunity
