immune cell
Pathogen-fighting corpuscle
An immune cell is any cell that participates in the body's defense against infection, disease, or foreign substances.
White blood cells—including lymphocytes, macrophages, and neutrophils—are the main types.
Immune cells identify and destroy pathogens, remember past infections, and coordinate inflammatory responses: The vaccine triggers immune cells to recognize the virus.
