What this means: Ccr10: predicted fine-region profile is strict-exclusive, with 10 positive regions out of 554 (limit 12); direct spatial validation is required.

Function in OV: evidence, prediction, innovation

Gene function
Ccr10 encodes CC chemokine receptor 10, a Gi-coupled GPCR for CCL27 (CTACK) and CCL28 (MEC), signalling via G protein, beta-arrestin and PI3K/Akt. Its known biology is immune-cell homing to skin and mucosa plus invasive tumour signalling.
Region function
The vascular organ of the lamina terminalis is a barrier-free circumventricular organ reading plasma osmolality, sodium, angiotensin II and inflammatory mediators to drive thirst, vasopressin release, sympathetic tone and fever.
Published in this region
none No region-specific literature found. Closest are CCR10 mRNA in brain parenchyma, changing in mouse hippocampal CA1 and dentate gyrus during and after pilocarpine-induced status epilepticus (Liu et al. 2007), and CCR10 upregulation in human glioma, where CCL27-CCR10 drives Akt-dependent proliferation and invasion (Chen et al. 2014).
Predicted function
Prediction: the barrier-free OVLT could let circulating CCL27/CCL28 act through CCR10 as a humoral immune signal on thirst and autonomic neurons. Gi inhibition predicts agonist infusion suppresses OVLT firing and reduces angiotensin-driven drinking and vasopressin release, while OVLT-restricted Ccr10 deletion exaggerates fluid intake and sympathetic responses to inflammation.
Innovation
★★★★★ 5/5 Nothing is published on CCR10 in any circumventricular organ, yet OVLT is a key homeostatic sensor with good circuit tools.
Tools
No neuroscience-validated driver line; recombinant CCL27/CCL28, anti-CCR10 antibodies and Ccr10 knockout/reporter mice exist in immunology; no selective antagonist. OVLT access uses Nr5a1-, Nxph4- or Adcyap1-based Cre strategies plus stereotaxic AAV.
