Background

Interleukin-2 (IL-2) is an interleukin, a type of cytokine immune system signaling molecule, which is a leukocytotropic hormone that is instrumental in the body natural response to microbial infection and in discriminating between foreign (non-self) and self. IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes, the cells that are responsible for immunity. Mature human IL-2 shares 56% and 66% aa sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit cross-species activity. The receptor for IL-2 consists of three subunits that are present on the cell surface in varying preformed complexes. IL-2 is also necessary during T cell development in the thymus for the maturation of a unique subset of T cells that are termed regulatory T cells (T-Regs). After exiting from the thymus, T-Regs function to prevent other T cells from recognizing and reacting against "self-antigens", which could result in "autoimmunity". T-Regs do this by preventing the responding cells from producing IL-2. Thus, IL-2 is required to discriminate between self and non-self, another one of the unique characteristics of the immune system.

Dog parents; buy this now!
Color: Black/White, Size: Medium
A must have for my pup! I have bought this at least 5 times. She eventually pops them and I need a new one. It's an amazing toy that she can thrash and we can play fetch with

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!

Not durable
Color: Black/White, Size: Large
If you have a dog who likes to pop things then this toy isn't it. Within 5 min she had this ball popped. It was made to sound like it was durable for this type of thing but it definitely is not so just be aware. Now if you have a dog who doesn't pop things easy then this would be a good toy
