The cells are EOSINOPHILS- which are stimulated by IL-5.

Default FA is the Bible !!!

Cells are eosinophils...
I think questions like this are asked to get hold of FA. When i saw this question i was searching for IL-4.Couldnt find.......
Then turned FA page 208 and saw IL-5 stimulates the growth and differentiation of eosinophils
