What are cytokines?
Q: What are cytokines?
A: Cytokines are a group of signalling molecules made by cells that help to control the immune system and fight disease.
Q: How are cytokines similar to hormones?
A: Cytokines are similar to hormones.
Q: Can cytokines carry signals between cells?
A: Yes, cytokines can carry signals locally between cells and these signals have an effect on other cells.
Q: What are cytokines made of?
A: Cytokines are made of proteins, peptides, or glycoproteins.
Q: What are some examples of cytokines?
A: Some well-known cytokines include interferon, prostaglandin and interleukins.
Q: How can cytokines be detected?
A: Cytokines can be detected using the ELISA and ELISPOT techniques.
Q: How do cytokines work?
A: Cytokines work by signal transduction. Each cytokine has a matching cell-surface receptor. Then cascades of signals inside the cell changes cell functions. This may include the regulation of several genes, the production of other cytokines, or an increase in surface receptors for other molecules.
