Activation of the cannabinoid CB1 receptor (CB1) is modulated by aspartate residue D2.63(176) in transmembrane helix (TMH) 2. Interestingly, D2.63 does not affect the affinity for ligand binding at the CB1 receptor. Studies in class A G protein-coupled receptors have suggested an ionic interaction between residues of TMH2 and 7. In this report, modeling studies identified residue K373 in the ex...
Background: Infertile couples in the reproductive failure, after a year of sex without contraception is described and in 10 to 15% of couples can be seen, that the 1/3 because of the male, 1/3 female and the rest are a common cause. Factors involved in human infertility, the expression of microbial infection (25%), biological factors, environmental and genetic (50%) and unknown causes (25%) are...
Incubation of INT407 cells with various clinical isolates of Campylobacter jejuni resulted in secretion of interleukin-8 (IL-8) at levels ranging from 96 to 554 pg/ml at 24 h. The strains which produced the highest levels of IL-8 secretion were 81-176 and BT44. Induction of IL-8 secretion required live cells of 81-176 and was dependent on de novo protein synthesis. Site-specific mutants of 81-1...
