Gene Information

human ... TACR1(6869)

Biochem/physiol Actions

Competitive substance P receptor antagonist. It is approximately 1000-fold more potent at cloned human NK-1 receptors than at cloned human NK-2 and NK-3 receptors; and approximately 200-fold more potent at human NK-1 receptors than at rat NK-1 receptors. The IC50 for the human NK-1 receptor expressed in CHO cells is approximately 2 nM.

The present study investigated a role of tachykinins (TK) and neurokinin (NK) receptors (NK-R) in the non-cholinergic regulation of omasal contractions in sheep. Semiquantitative reverse transcription (RT)-PCR revealed that both preprotachykinin (PPT)-A and PPT-B mRNA were distributed in the omasal

European journal of pharmacology, 556(1-3), 157-165 (2006-12-13)
Transient receptor potential ion channel of the vanilloid type 1 (TRPV1)-dependent pathway, consisting of capsaicin-sensitive tachykininergic primary afferent and myenteric nitrergic neurons, has been suggested to mediate the inhibitory effect of capsaicin on vagally mediated striated muscle contractions in the

Hyperalgesia in animal injury models is linked to activation of descending raphespinal modulatory circuits originating in the rostral ventromedial medulla (RVM). A neurokinin-1 (NK-1) receptor antagonist microinjected into the RVM before or after inflammation produced by complete Freund's adjuvant (CFA)

International journal of obesity (2005), 43(2), 331-343 (2018-08-08)
The murine model of high fat diet (HFD)-induced obesity is characterized by an increment of intestinal permeability, secondary to an impairment of mucosal epithelial barrier and enteric inflammation, followed by morphofunctional rearrangement of the enteric nervous system. The present study

Pain, 129(1-2), 195-209 (2007-02-24)
Inhibitory neurotransmission in spinal cord dorsal horn is mainly mediated by gamma-amino butyric acid (GABA) and glycine. By patch clamp recordings and correlative immunocytochemistry, we studied here the effect of 2 microM capsaicin-induced vanilloid receptor-1 (TRPV1) activation on IPSCs in
