question 6

Multiple Choice

Eosinophils are a subset of granulocytes that normally reside in the circulation. When activated, these cells secrete toxic compounds that are a key component in the eradication of helminthic parasite infections. Eosinophils are recruited to sites of parasite infections by:

• A) Interferon-\(\gamma\) produced by T_H1 cells
• B) CCL11 produced by T_H2 cells
• C) Interferon-\(\gamma\) produced by CD8 cytotoxic T cells
• D) CCL20 produced by T_H17 cells
• E) GM-CSF produced by T_H1, T_H2, and T_H17 cells
