Resistance to HIV-1 infection in caucasian individuals bearing mutant alleles of the CCR-5 chemokine receptor gene.

TL;DR: It is shown that a mutant allele of CCR-5 is present at a high frequency in caucasian populations, but is absent in black populations from Western and Central Africa and Japanese populations, and a 32-base-pair deletion within the coding region results in a frame shift, and generates a non-functional receptor that does not support membrane fusion or infection by macrophage- and dual-tropic HIV-1 strains.
Journal ArticleDOI

The metastasis suppressor gene KiSS-1 encodes kisspeptins, the natural ligands of the orphan G protein-coupled receptor GPR54.

TL;DR: Stimulation of oxytocin secretion after kisspeptin administration to rats confirmed this hypothesis that human GPR54 was highly expressed in placenta, pituitary, pancreas, and spinal cord, suggesting a role in the regulation of endocrine function.
Journal ArticleDOI

Unresponsiveness to Cannabinoids and Reduced Addictive Effects of Opiates in CB1 Receptor Knockout Mice

TL;DR: Observations suggest that the CB1 receptor is involved in the motivational properties of opiates and in the development of physical dependence and extend the concept of an interconnected role of CB1 and opiate receptors in the brain areas mediating addictive behavior.
Journal ArticleDOI

Functional characterization of human receptors for short chain fatty acids and their role in polymorphonuclear cell activation.

TL;DR: The pharmacology of GPR43 matches indeed the effects of SCFAs on neutrophils, in terms of intracellular Ca2+ release and chemotaxis, and might constitute a target allowing us to modulate immune responses in these pathological situations.
