Pentraxin 3

Pentraxin 3 (PTX3) is a protein produced by immune cells in response to inflammation or infection. It plays a role in the body's early defense system by helping recognize pathogens, clearing damaged cells, and regulating inflammation. PTX3 acts as a marker indicating that the body is responding to an injury or infection. It is involved in innate immunity, which provides immediate, non-specific defense against threats, and may also influence tissue repair processes. Elevated PTX3 levels can help doctors assess the presence and severity of inflammation or disease.
