GlossaryPlasma Cell

A plasma cell is a type of white blood cell that originates from B lymphocytes and is primarily responsible for producing antibodies. In the context of hair loss, plasma cells can be relevant in autoimmune conditions such as alopecia areata, where the immune system mistakenly attacks hair follicles. Key distinguishing characteristics of plasma cells include their large size, abundant cytoplasm, and a prominent nucleus, which is often eccentrically located. Understanding the role of plasma cells in immune responses can provide insights into the mechanisms underlying certain types of hair loss.
