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.
