CD68 is a heavily glycosylated type I transmembrane protein belonging to the lysosomal-associated membrane protein (LAMP) family. The protein consists of:
The protein undergoes extensive post-translational modifications including N-linked and O-linked glycosylation, which contributes to its molecular weight heterogeneity.
In the central nervous system, CD68 is primarily expressed by:
CD68 functions as a scavenger receptor involved in:
Within healthy brain tissue, CD68+ microglia exhibit surveillance phenotypes, constantly scanning their environment and maintaining tissue homeostasis.
CD68 is a key marker of microglial activation in neurodegenerative diseases:
CD68 is primarily used as a biomarker for microglial activation rather than a direct therapeutic target. However:
