CD1a

CD1a is a molecule found on the surface of certain immune cells called antigen-presenting cells. Its main role is to help the immune system recognize and respond to specific substances, particularly lipid-based antigens like those from certain bacteria, fungi, or skin-related conditions. By presenting these lipid molecules to other immune cells, CD1a helps coordinate immune responses, including immune surveillance and defense. It is especially relevant in skin immunity and conditions such as psoriasis and contact dermatitis, where immune regulation is disrupted.
