Cytokines are crucial signalling molecules that facilitate intercellular communication, primarily by regulating the immune system, promoting cell growth and differentiation, and modulating inflammatory responses. Our comprehensive cytokine poster compiles detailed information on 230+ cytokines, including molecular weight, receptors, targets, cellular sources, and functions. Presented in a format inspired by the periodic table of elements, this resource provides researchers with an efficient reference tool to support cytokine-related research endeavours.
