Background

Interleukin 4 (IL-4) was first identified as a helper T cell product with the capacity to co-stimulate B cell growth in vitro. IL-4 also can rescue B-cells from apoptosis, enhancing their survival, and is responsible for immunoglobulin isotype switching to IgG1 and IgE. The effect of IL-4 signaling is mediated through the IL-4 receptor alpha chain (IL-4Rα). Upon binding to its ligand, IL-4Rα dimerizes either with the common gamma chain (γc) to produce the type-1 signaling complex located mainly on hematopoietic cells, or with the IL-13 receptor alpha 1 (IL-13Rα1) to produce the type-2 complex, which is expressed also on non-hematopoietic cells. The type-1 signaling complex is critical for Th2-skewing of T cells and the development of alternatively activated macrophages (AAMΦs), while the type-2 complex plays a role in non-hematopoietic responses to IL-4 and IL-13.

Good for little guys who don’t like hard toys
Size: Volleyball
Good sized ball for little mouths that have a hard time gripping hard or medium to latge balls. Soft, fluffy and not too big for small dogs with bite or teeth issues. Really cute, colorful, light weight.

Good quality, lotsa fun

I wanted to train my dog to shoot basketball but he loves this ball so much as a toy that I had to find something else for the basketball game and let him play as much as he wants with this one
