protein complex essential for T-cell activation in immune response
CD3 is a protein complex and a crucial part of the T-cell receptor (TCR) on immune cells called T lymphocytes. It plays a vital role in activating these cells, which are essential for the body's immune response. In the context of alopecia, understanding CD3 can be important because T cells can sometimes mistakenly attack hair follicles, leading to hair loss.
