細胞激素受器(Cytokine receptor)

細胞激素受器是和細胞激素節的東西
在最近幾年，細胞激素受器的研究已經超越細胞激素本身，主要是因為她們扮演重要的角色以及缺乏細胞激素受器會造成某些免疫缺陷，另外因為細胞激素的pleiotropy （基因多效性）、redundancy(基因重複性)，藉由細胞激素受器會比較有實用價值

Type	Examples	Structure	Mechanism
type I cytokine receptor=Hematopoietin	Type 1 interleukin receptors Erythropoietin receptor GM-CSF receptor G-CSF receptor growth hormone receptor prolactin receptor Oncostatin M receptor Leukemia inhibitory factor receptor	Certain conserved motifs in their extracellular amino-acid domain. Connected to Janus kinase (JAK) family of tyrosine kinases	JAK phosphorylate and activate downstream proteins involved in their signal transduction pathways
type II cytokine receptor=Interferon	Type II interleukin receptors interferon-alpha/beta receptor interferon-gamma receptor
Many members of theimmunoglobulin superfamily=Interleukin-1 family	Interleukin-1 receptor CSF1 C-kit receptor Interleukin-18 receptor	Share structural homology with immunoglobulins (antibodies), cell adhesion molecules, and even some cytokines.
Tumor necrosis factor receptor family	CD27 CD30 CD40 CD120 Lymphotoxin beta receptor	cysteine-rich common extracellular binding domain
chemokine receptors	Interleukin-8 receptor CCR1 CXCR4 MCAF receptor NAP-2 receptor	Seven transmembrane helix	G protein-coupled
TGF beta receptors	TGF beta receptor 1 TGF beta receptor 2
