The story of the word

Stanley Cohen proposed the term in 1974 to gather up the growing crowd of immune messengers that were each being named separately. Kytos meant a jar or any hollow before biology took it for the cell. Kinein is the piece inside cinema, which started life as kinematograph, a writer of movement. A cytokine storm is that signalling system running away from its own controls.
