Background

Interleukin-4, also known as IL4, is a secreted protein which belongs to the IL-4 / IL-13 family. Interleukin-4 / IL4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation.In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, And this cytokine is a ligand for interleukin 4 receptor.

Pups like them
Size: 4 Inch (Pack of 2)
It took a little bit but once my dogs started chewing on them they seem to like them. They're holding up pretty well and not destroying them too quickly like they did some other chews.
