SEVILLE, Spain, May 18, 2017-Scientists at the University of Seville and the Seville Institute of Biomedicine (IBiS) have just published a scientific article in which they show that mother cells from the adult carotid body can transform into blood vessels, as well as into neurons.
Other lesions include fungal infections, pituitary adenoma, schwannoma, neurofibroma, carotid body paraganglioma, craniopharyngioma, arachnoid cyst, medulloblastoma and medulloepithelioma.
This systematic review included healthy, physically inactive people, then people with mild hypertension, congestive heart failure, obstructive sleep apnea and people who underwent therapeutic carotid body resection, as well as professional athletes.
Scientists believe blood pressure can rise when the carotid body "thermostat" is set too high.
Since the swelling was in the anterior neck region, we excluded lateral neck swellings like branchial cysts, solitary lymphatic cysts, and carotid body tumors.
To the Editor: Carotid body tumor (CBT) is a highly vascular neoplasm of neural crest origin arising in paraganglial cells of the carotid bifurcation.
When observing changes in expression of TNF-[alpha] and IL-1[beta] in the carotid body of SD rats after 21 days of CIH exposure, researchers [44] found that CIH exposure significantly enhanced the levels of TNF-[alpha] and IL-1[beta] and that ibuprofen effectively suppressed the CIH-induced enhancement of TNF-[alpha] and IL-expression.

A CT scan demonstrated a right-sided 2 cm mass located between the external and internal carotid arteries that enhanced with contrast and caused splaying of the carotid bifurcation, suggesting a carotid body tumor (Figure A).
MRI is often preferred over computed tomography because it can distinguish tumors of the deep parotid lobe from neurogenic lesions and carotid body tumors; MRI also delineates a tumor's relation to the internal carotid artery.
Researchers at Britain's Bristol University found that in rats with high blood pressure, when they removed nerve links between the brain and the carotid body - a nodule about the size of a grain of rice on the side of each carotid artery - the animals' blood pressure fell and remained low.
The carotid body is a small nodule- no larger than a rice grain- found on the side of each carotid artery and it appears to be a major culprit in the development and regulation of high blood pressure.
