Task: Answer Verification
Input (English): Question: Do conjunctival fibroblasts enhance the survival and functional activity of peripheral blood eosinophils in vitro?
Answer: Human conjunctival fibroblasts induced prolonged survival and increased secretory function of human peripheral blood eosinophils. Increased survival is partially mediated by IL-3, IL-5, and GM-CSF. The coculture of conjunctival fibroblasts with eosinophils can serve as an in vitro system for the study of eosinophil behavior in the ocular surface and of cellular interactions in allergic eye diseases.
Output (English): yes
