Peripheral blood mononuclear cells

Peripheral blood mononuclear cells (PBMCs) are a type of immune cell found in the bloodstream that have a single round nucleus. They include lymphocytes (such as T cells, B cells, and natural killer cells) and monocytes. These cells are essential for the immune system's response to infections, cancer, and other diseases. PBMCs are often collected for medical tests or research because they play a key role in immune defense, inflammation, and immune regulation. Their ability to be easily isolated from blood makes them valuable for studying immune function and developing treatments.
