Background

CD5 protein is a type-I transmembrane glycoprotein found on the surface of thymocytes, T lymphocytes, and a subset of B lymphocytes. It serves to mitigate activating signals from the BCR, allowing B-1 cells to be activated only by strong stimuli. Additionally, CD5 is involved in regulating lipid synthesis and inflammatory responses.
