Question

Quizplus · Accepted Answer

Eosinophils attach to the surface of parasitic helminths (worms) and produce toxins that kill the parasite, which is an important defense mechanism against parasitic infections. They do not produce defensins or secrete toxins onto virally infected cells, and are not typically involved in the removal of neoplastic cells. While eosinophils may spare some normal cells, they are also known to contribute to inflammation and tissue damage in certain conditions.
