    What is the primary distinction between immunotolerance and autoimmune diseases?

    <p>Immunotolerance involves the suppression of immune responses to prevent harm to the body, whereas autoimmune diseases occur when the immune system mistakenly attacks healthy cells and tissues.</p> Signup and view all the answers

    How do hypersensitivities relate to immunodeficiencies?

    <p>Hypersensitivities involve an overactive immune response, whereas immunodeficiencies involve a weakened or impaired immune response.</p> Signup and view all the answers

    What is the common link between blood-borne infections and sexually transmitted infections (STIs)?

    <p>Both blood-borne infections and STIs are types of infectious diseases that can be transmitted through bodily fluids.</p> Signup and view all the answers

    What is the primary consequence of a lack of immunotolerance in the context of autoimmune diseases?

    <p>The primary consequence is the immune system's attacks on healthy cells and tissues, leading to tissue damage and disease.</p> Signup and view all the answers

    How do immunodeficiencies and autoimmune diseases both contribute to the development of diseases?

    <p>Immunodeficiencies increase the susceptibility to infections, while autoimmune diseases lead to tissue damage and disease through the immune system's attacks on healthy cells and tissues.</p> Signup and view all the answers

    Study Notes

    Hypersensitivities

    • Hypersensitivities can be classified into different categories

    Immunotolerance/Suppression

    • Immunotolerance occurs when the immune system fails to respond to an antigen
    • Immunological tolerance can be specific or non-specific
    • Suppression occurs when the immune response is actively suppressed

    Autoimmune Diseases

    • Autoimmune diseases occur when the immune system attacks the body's own tissues
    • Examples of autoimmune diseases include rheumatoid arthritis and lupus
    • Autoimmune diseases can be classified into different types

    Immunodeficiencies

    • Immunodeficiencies occur when the immune system is weakened or absent
    • Examples of immunodeficiencies include HIV and severe combined immunodeficiency (SCID)
    • Immunodeficiencies can be classified into different types

    Blood Borne Infections

    • Blood-borne infections can be transmitted through blood products or infected needles
    • Examples of blood-borne infections include HIV and hepatitis
    • Blood-borne infections can be classified into different types

    Sexually Transmitted Infections (STIs)

    • Sexually transmitted infections (STIs) are caused by bacteria, viruses, or parasites
    • Examples of STIs include chlamydia, gonorrhea, and syphilis
    • STIs can be classified into different types

    Hypersensitivities
