    Study Notes

    Acquired Immunity

    • The body's second line of defense against infection, activated after innate immunity fails.
    • Relies on B & T lymphocytes.

    Types of Acquired Immunity

    • Humoral Immunity: Involves B lymphocytes producing antibodies to neutralize antigens.
    • Cell-mediated Immunity: Involves T cells activating macrophages and releasing cytokines to combat antigens.

    Formation of B & T Lymphocytes

    • Common lymphoid progenitor cells develop into hematopoietic stem cells.
    • B cells mature in the bone marrow.
    • T cells mature in the thymus.
    • B and T cells are activated in peripheral lymphoid tissue when they encounter an antigen.

    Activation of B Lymphocytes

    • B cells bind to antigens through cell surface receptors.
