What cell type is responsible for responding to parasites?

Eosinophils are the cell type specifically known for their role in responding to parasitic infections. These white blood cells are characterized by their ability to release cytotoxic granules containing enzymes and proteins that are effective against larger parasites, such as helminths (worms). When the body detects a parasitic infection, eosinophils are recruited to the site of infection, where they can degranulate and release substances like major basic protein, eosinophil peroxidase, and eosinophil cationic protein, all of which can damage or destroy parasites.

In addition to their role in combating parasitic infections, eosinophils are also involved in allergic reactions and asthma, but their primary function in the context of this question is in the defense against parasitic organisms. Understanding the unique functions of different white blood cells is crucial for grasping how the immune system operates and responds to various types of pathogens.
