Cidea control of lipid storage and secretion in mouse and human sebaceous glands.

Mol Cell Biol 2014 May 17;34(10):1827-38. Epub 2014 Mar 17.

MOE Key Laboratory of Bioinformatics and Tsinghua-Peking Center for Life Sciences, School of Life Sciences, Tsinghua University, Beijing, People's Republic of China.

Sebaceous glands are skin appendages that secrete sebum onto hair follicles to lubricate the hair and maintain skin homeostasis. In this study, we demonstrated that Cidea is expressed at high levels in lipid-laden mature sebocytes and that Cidea deficiency led to dry hair and hair loss in aged mice. In addition, Cidea-deficient mice had markedly reduced levels of skin surface lipids, including triacylglycerides (TAGs) and wax diesters (WDEs), and these mice were defective in water repulsion and thermoregulation.

Authors:
M Haffner

Ann Anat 1998 Apr;180(2):165-71

Zoologisches Museum der Universität Zürich, Winterthurerstrasse.

Many large sebaceous glands have been described, and functions such as scent production suggested, but gland size has seldom been studied in relation to the surface area of their hair follicles. However, investigating this relationship is essential for establishing whether glands produce more sebum than would be required for lubricating associated hair alone. Here, the relationship between sebaceous gland size and the surface area of the associated hair follicles has been studied. Read More

Physiology, pathophysiology, and anthropology/epidemiology of human earcanal secretions.

J Am Acad Audiol 1997 Dec;8(6):391-400

Callier Center for Communication Disorders/University of Texas at Dallas 75235, USA.

Two types of glands are found in the outer third of the human earcanal: sebaceous glands that produce sebum and modified apocrine glands that produce apocrine sweat. Together, these substances make up cerumen, which serves to clean, lubricate, and, to some extent, protect the earcanal from bacteria and fungus. Excessive/impacted cerumen can cause tinnitus, vertigo, itching, pain, external otitis, and hearing loss. Read More
