气体信号分子是生物体及细胞内存在的一种具有独特生物学作用的信号途径,具有连续产生、传播和弥散迅速等特点。该命题是随着20世纪80年代中期发现内源性气体分子一氧化氮(NO)通过一氧化氮合酶作用于精氨酸而产生并与细胞内鸟氨酸环化酶结合从而提高胞内环磷酸鸟苷(cGMP)水平并具有舒张血管、抑制血小板聚集和抑制细胞
Gas signaling molecule is a kind of signal path that has unique biological function in living organism and cell. It has such characteristics as continuous generation, rapid propagation and dispersion. The proposition is that with the discovery of the endogenous gas molecule nitric oxide (NO) produced by the nitric oxide synthase in arginine and the intracellular ornithine cyclase in the mid-1980s, Cyclic guanosine monophosphate (cGMP) levels and have vasodilatation, inhibition of platelet aggregation and inhibition of cells
