Description

Biochem/physiol Actions

COG 1333 or apoE(133-149) is a fragment of Apolipoprotein E (APOE) that mimics the functional anti-inflammatory and neuroprotective effects of the intact apoE protein. It was suggested that neuroprotective functions of the mimetic results from binding to the low-density lipoprotein receptor-related protein (LRP) or LDL receptors, and such binding results in inhibition of the N-methyl-D-aspartate (NMDA) receptor.
