cord factors

Description

Cord Factors: Toxic glycolipids composed of trehalose dimycolate derivatives. They are produced by MYCOBACTERIUM TUBERCULOSIS and other species of MYCOBACTERIUM. They induce cellular dysfunction in animals. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]
