| Research Abstract |
Arterial chemoreceptors, carotid and aortic bodies, sense arterial CO_2 as well as low oxygen. In the present study, rats exposed to hypercapnia, hypoxia and hypercapnic-hypoxia in order to analyze hypercapnic modulation of molecular expression in the carotid body. As a result, alteration of molecular expression in rats exposed hypercapnia shows lower effect than hypoxia. Furthermore, carbon dioxide delay the expression of some molecules that increased by hypoxia.
