【 摘 要 】

Most of the recently cloned cytokine receptors that operate in the immune and hematopoietic systems contain no tyrosine kinase domains in their cytoplasmic regions, unlike the family of growth factor receptors defined earlier. However, they can be assigned to several new types of receptor families based on structural similarities among them. It is characteristic of these receptors that many of them require a receptor-associated molecule in order to achieve high-affinity ligand binding and/or transmission of cytoplasmic signals. Receptor-associated molecules have been found that transduce cytoplasmic signals and are shared by different cytokine receptors. Phosphorylation of the receptors and of various cytoplasmic proteins after ligand stimulation seems to be a common event in cytokine systems. Insight into the pleiotropic and redundant nature of cytokine action is provided by the discovery of several new cytokine receptor families and of shared signal transduction molecules and by the idea that several cytoplasmic kinases may be able to functionally substitute for one another in transmitting cytokine signals.
