چکیده انگلیسی
Although acid-sensitive ion channels (ASICs) play an important role in brain functions, the exact mechanism of their physiological activation remain unclear. A possible answer to the intriguing question is that some presently unknown endogenous ligand(s) positively modulate ASICs and enhance their responses to physiologically significant level. In the present work we found that histamine selectively potentiates ASIC1a homomers in CHO cells. Action of histamine was particularly pronounced at modest acidifications, which cause minor response. At these conditions micromolar concentrations of histamine have provided significant potentiation of ASIC1a response. We proposed that histamine and possibly some other endogenous amines can positively modulate ASICs functions.
