n.
1. Physiology A specialized cell or group of nerve endings that responds to sensory stimuli.

re·cep·tor

(rĭ-sĕp′tər)
1. A nerve ending specialized to sense or receive stimuli. Skin receptors respond to stimuli such as touch and pressure and signal the brain by activating portions of the nervous system. Receptors in the nose detect odors.
2. A cell structure or site that is capable of combining with a hormone, antigen, or other chemical substance.

The anti-inflammatory mechanisms associated with the control of the immune response, elicited to maintain homeostasis, involve the release of anti-inflammatory cytokines (IL-4, IL-10, IL-13), the decrease expression of cytokine receptors, and the release of soluble cytokine receptors or receptors antagonists (36).
(6) Genetic factors may also have important roles and many studies have been performed to determine the variations of genes for cytokines and cytokine receptors. (7,8)
NF-[kappa]B and AP-1 promote expression of innate immune cytokines, such as tumor necrosis factor alpha (TNF-[alpha]) and interleukin 1 beta (IL-1[beta]), as well as ofTLRs and cytokine receptors (see figure 1).
The cytokine receptors are composed of heterotrimeric chains one of which is shared amongst these family members--the common [gamma] chain as the signaling component.
Besides IL-1[beta], IL-2, IL-4, IL-6, IL-17, IL-22, and TNF-[alpha], several other cytokines such as IL-10, interferon-[gamma] (IFN-[gamma]), transforming growth factor (TGF)-[beta], erythropoietin (EPO), cytokine receptors such as the TNF-[alpha] receptors TNF-R p55 and TNF-Rp75, and cytokine receptor antagonists such as the IL-1 receptor antagonist (IL-1ra) have been implicated in the pathophysiology of psychiatric and neurological disorders [2, 92, 93].
Although cytokine receptors lack intrinsic kinase activity, they are constitutively associated with members of JAK family of protein tyrosine kinases, which include JAK1, JAK2, JAK3, and tyrosine kinase 2 (TYK2).
