Congenital ablation of Tacr2 reveals overlapping and redundant roles of NK2R signaling in the control of reproductive axis.
Title: Congenital ablation of Tacr2 reveals overlapping and redundant roles of NK2R signaling in the control of reproductive axis.
Tacr2 negatively regulated the expression of neuronal nitric oxide synthase (nNOS) and vasoactive intestinal polypeptide (VIP). Its ablation in mice elevated the expression of nNOS and VIP, enhanced nitric oxide signaling and changed the Creb and NF-kappaB signalings, finally leading to the gastric emptying disturbance of Tacr2(-/-) mice.
Title: Ablation of Tacr2 in mice leads to gastric emptying disturbance.
NK2R-dependent neuropeptide signaling regulates Ag-specific T cell responses via activation of DC function
Title: Neuropeptide signaling activates dendritic cell-mediated type 1 immune responses through neurokinin-2 receptor.
mouse hemokinins are tachykinin NK(1) receptor-preferring uterotonic agonists in non-pregnant mice but lack action at the myometrial tachykinin NK(2) receptors present in late pregnant mice
Title: Functional characterisation of hemokinin-1 in mouse uterus.
In mouse colon, both NK1 and NK2 receptors are junctionally activated by endogenous tachykinins to cause an additive response. NK2 receptors seem to be present exclusively on smooth muscle cells.
Title: Role for NK(1) and NK(2) receptors in the motor activity in mouse colon.
Tachykinin NK2 receptor genes are expressed in uterine cells, oocytes, ovaries and embryos from mice, and may play a role in female reproductive function.
Title: A role for tachykinins in female mouse and rat reproductive function.
NK-1R and NK-2R have important but differential roles in the regulation of cutaneous inflammatory responses
Title: Cutaneous allergic contact dermatitis responses are diminished in mice deficient in neurokinin 1 receptors and augmented by neurokinin 2 receptor blockage.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
