Nitric oxide and carotid body chemoreception

Biological Research, 2001
Nitric oxide (NO) has been proposed as an inhibitory modulator of carotid body chemosensory responses to hypoxia. It is believed that NO modulates carotid chemoreception by several mechanisms, which include the control of carotid body vascular tone and ...

Influence of brief carbon dioxide inhalation on acute exercise performance and recovery: A pilot study

Physiological Reports, Volume 14, Issue 12, June 2026.
Abstract Brief inhalation of carbon dioxide (CO2) has been proposed to counteract transient hypocapnia by enhancing oxygen unloading, vasodilation, and sympathetic modulation. Despite these potential ergogenic mechanisms, CO2 has rarely been investigated in the exercise context.

Chemoreceptor activity is normal in mice lacking the NK1 receptor

, 2013
Substance P has been proposed to be an important neurotransmitter in the carotid body with the neurokinin 1 (NK1) receptor, mediating excitation between the glomus cells and afferent nerve endings.

Control of flagellar gene expression by a chemotaxis receptor-like regulator in pathogenic Escherichia coli

The EMBO Journal
Chemoreceptors enable bacteria to modulate their swimming behavior in response to the perceived environmental cues. Despite the large diversity of stimuli sensed by bacterial chemoreceptors, their output to the chemotaxis pathway that controls the ...

Pituitary Neurolobectomy induces sustained hypotension in male Wistar rats and normalizes blood pressure in male spontaneously hypertensive rats

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Arginine vasopressin is primarily recognized as an osmoregulatory hormone; however, its contribution to vascular tone and blood pressure regulation under basal and hypertensive conditions remains debated. This study examined the effects of vasopressin deficiency induced by neurointermediate pituitary lobectomy in Wistar and spontaneously ...

ATP and mechanisms of central CO2 chemosensitivity [PDF]

ATP release from the surface of the ventro-lateral medulla (VLM) is integral to the hypercapnic response in vivo and can be seen in vitro. By employing horizontal slices of the ventral medulla containing the ventral chemosensitive nuclei, I have ...
