🧠Questions & Answers from Immunity – MBBS Pathology
Q1: What is the difference between innate and adaptive immunity?
Ans: Innate immunity is the first line of defense, non-specific, and present since birth. Adaptive immunity is specific, has memory, and is acquired after exposure.
Q2: Name the four types of hypersensitivity reactions with examples.
Ans:
- Type I – IgE-mediated (e.g., anaphylaxis)
- Type II – Antibody-mediated cytotoxic (e.g., hemolytic anemia)
- Type III – Immune complex (e.g., SLE)
- Type IV – Delayed-type, cell-mediated (e.g., TB skin test)
Q3: What is MHC and why is it important?
Ans: MHC (Major Histocompatibility Complex) are molecules on cells that present antigens to T-cells. MHC-I presents to CD8+ T-cells; MHC-II to CD4+ T-cells. They are crucial for immune recognition and graft compatibility.
Q4: Define autoimmunity with an example.
Ans: Autoimmunity is a failure of the immune system to recognize self-antigens, leading to immune attacks on one’s own tissues. Example: Rheumatoid arthritis.
