"eosinophil"の定義と意味

What is an "eosinophil"?

An eosinophil is a type of white blood cell that plays a crucial role in the immune response of the human body. It is characterized by its distinct granular appearance and contains granules filled with toxic substances. Eosinophils are primarily involved in combating parasitic infections and mediating allergic reactions. They are attracted to sites of inflammation and help regulate immune responses by releasing cytokines and other signaling molecules. Eosinophils also play a role in tissue repair and can modulate the activity of other immune cells.
