Questions and Answers

What is the main function of innate immunity?

  • Provide delayed protection against pathogens
  • Activate leukocytes and plasma proteins

  • What distinguishes innate immunity from adaptive immunity?

  • Lacks memory response (correct)
  • Has gene-encoded receptors

    Study Notes

    Main Function of Innate Immunity

    • Provides the first line of defense against pathogens.
    • Responds rapidly and non-specifically to invading microorganisms.

    Distinction from Adaptive Immunity

    • Innate immunity is present at birth; adaptive immunity develops over time.
    • Adaptive immunity improves with exposure to specific pathogens, while innate immunity does not.

    Characteristics of Defects in Innate Immunity

    • Can lead to increased susceptibility to infections and inflammatory diseases.
    • May result in poor response to common pathogens due to the inability of innate immune cells to function properly.

    Response Associated with Innate Immunity

    • Involves immediate responses such as inflammation, phagocytosis, and recruitment of immune cells.
    • Activation of complement system enhances the ability to clear pathogens.

    Main Feature of Innate Immunity's Receptors and Effectors

    • Utilizes pattern recognition receptors (PRRs) to identify common features of pathogens (e.g., bacteria, viruses).
    • Effectors include physical barriers (skin), immune cells (macrophages, neutrophils), and soluble proteins (cytokines, chemokines) that respond quickly to threats.
