    Study Notes

    Cytokines and Interferons

    • Macrophages, T cells, and B cells produce cytokines.
    • Cytokines do not have a direct role in antibody production.
    • Interleukin 4 (IL-4) acts as a regulator of allergic reactions.
    • Fibroblasts, epithelial cells, and immune cells produce interferons.
    • There are three classes of interferons: alpha, beta, and gamma.
    • Growth factor is not an interleukin.
    • Viral infections trigger the production of interferons.
    • IL-8 acts as a chemoattractant.
    • Interleukins do not have a direct role in antibody production.
    • T cells, B cells, and macrophages produce IL-4.
    • Cytokines activate immune cells, induce inflammation, and regulate immune responses.
    • Leukocytes, in general, produce interleukins.
    • Interleukins do not have a direct role in phagocytosis.
    • Interleukin 12 (IL-12) is an interleukin.
    • Interferons inhibit viral replication and induce antiviral proteins.
    • Fibroblasts, epithelial cells, and immune cells produce interferons.
    • Omega is not a class of interferons.
    • Viral infections trigger the production of cytokines.
    • IL-4 promotes the growth and differentiation of B cells.
    • There are over 30 identified interleukins.
    • Cytokines do not have a direct role in phagocytosis.
    • Interleukin 12 (IL-12) is an interleukin.
    • IL-8 acts as a chemoattractant.
    • Interleukin 4 (IL-4) acts as a regulator of allergic reactions.
    • Fibroblasts, epithelial cells, and immune cells produce interferons.
