Cytokines despite being nonspecific immunity it regulate the intensity and duration of the inflammatory/immune response.. Most cytokines are single polypeptide chains, may be aggregate as a homotrimer e.g. IL-12, IL-23. ®. Cytokines are rapidly secreted upon expression which results in. low / not detectable intracellular concentrations.. The use of secretion inhibitors allows for intracellular accumulation of cytokines:. Second lecture. Sept 3, 2020. 9/3 . Lecture: .
