We investigated the response of renal nerve activity (RNA) to hypercapnia and assessed the contribution of the peripheral chemoreceptors to the response of RNA in anesthetized and artificially ventilated cats. RNA and arterial pressure were recorded at four levels of [formula omitted] with hyperoxia in intact and in peripheral chemoreceptor denervated cats. In intact cats, RNA increased progressively with increasing [formula omitted], while no consistent change in arterial pressure was observed. In peripheral chemoreceptor denervated cats, the response of RNA to increasing [formula omitted] was totally abolished. These results suggest that the peripheral chemoreceptors play an important role in increasing RNA during hypercapnia.
