    Study Notes

    Immune System

    • The primary function of the immune system is to defend against infectious disease-causing microbes.
    • The term "immunity" is derived from the Latin word "immunitas," meaning protection of Roman politicians from prosecution.

    Primary Physiologic Function

    • The primary physiologic function of the immune system is to eradicate established infections.

    Vaccination

    • Edward Jenner was the first to make a vaccine.

    Innate Immunity

    • Innate immunity has a rapid response to microbes.
    • It reacts in essentially the same way to repeated infections.
    • It exists prior to infection.
    • It does not have memory.

    Adaptive Immunity

    • Adaptive immunity is characterized by a delayed response but has memory.
    • It has strict specificity for distinct macromolecules associated with a pathogen.
    • It can stimulate innate immunity and influence its nature.

    Humoral Immunity

    • B lymphocytes are primarily responsible for humoral immunity.
    • Humoral immunity is not effective against intracellular microbes.

    Cellular Immunity

    • Cellular immunity is effective against intracellular microbes such as viruses and some bacteria.
    • It is important for defense against intracellular microbes.

    Passive Immunity

    • Passive immunity involves the transfer of serum antibodies or lymphocytes from an immune individual to a naive individual.
    • It does not generate memory and is not long-lasting.

    Clonal Selection Hypothesis

    • The clonal selection hypothesis states that only lymphocytes bearing an antigen-specific receptor will become activated during an adaptive immune response.
    • It also states that a given lymphocyte produces only one type of antigen-specific molecule.

    Adaptive Immune Responses

    • Adaptive immune responses are capable of clonal expansion in response to antigen stimulation.
    • They have memory and can respond more vigorously to repeated exposure to the same microbe.
    • Immunological memory refers to the immune system's ability to remember past infections and respond more effectively to subsequent exposures.
