Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors
eLife, 2022 Mammalian carotid body arterial chemoreceptors function as an early warning system for hypoxia, triggering acute life-saving arousal and cardiorespiratory reflexes. To serve this role, carotid body glomus cells are highly sensitive to decreases in oxygen

The Carotid Body a Common Denominator for Cardiovascular and Metabolic Dysfunction?
Frontiers in Physiology, 2020 The carotid body is a highly vascularized organ designed to monitor oxygen levels. Reducing oxygen levels in blood results in increased activity of the carotid body cells and reflex increases in sympathetic nerve activity.

Carotid Body Size on CT Angiography in Patients With COVID-19 Pneumonia. [PDF]
Br J Biomed SciPurposeMany pathophysiological theories have been expressed regarding increased sympathetic activity along with respiratory failure in patients with COVID-19 pneumonia. In addition, the carotid bodies, which are directly related to increased blood oxygen

Carotid Body Tumour: A Rare Case Report [PDF]
International Journal of Anatomy Radiology and Surgery, 2017 Carotid Body Tumour (CBT) is a uncommon tumour which arises from a chemoreceptor tissue, which is present at the bifurcation of common carotid arteries. Not many case reports have been reported for carotid body tumours. We report an unusual case of a

STUDIES OF CAROTID BODY AND CAROTID SINUS: FINE STRUCTURE OF CAROTID BODY
Nihon Naika Gakkai Zasshi, 1966 古くから頚動脈洞反射にかんする研究は多く, 総頚動脈分岐部には, 圧受容体と化学受容体の存在することは多くの生理学者が認めるものである. これらにかんして, イヌを用いて, 頚動脈洞を刺激し, その血中カテコールアミン体の変動を認め, さらに, 動脈血中の化学成分の変化によつて起こる呼吸反射をみとめ, 先人の業績を確認しながら, 組織像を追究した. ことに, 電顕像および組織化学的方法によつても, 頚動脈体は, 腺でも単なる血管糸球でもなく, 傍神経節でもなく, クローム親和性細胞も認められず, いわゆる頚動脈体と呼称されるのにふさわしい臓器であることを認め, さらに, 頚動脈洞壁の微細構造と比較検討し, 本小体が化学受容体とされて当然のことと結語した.
