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.

Happier feet for my toddler
Size: 8 Toddler, Color: Navy
My son was having some issues with a store brand shoes, I think his fit may have been a little too wide. It caused him enough pain he would take off his shoes. So I opted to invest in these Stride Rites. He doesn't want to use any other shoes. They are easy to get on, they fit him well. I like the fact that you can take out the inside of your child has wider feet. Instead of buying multiple cheaper shoes I'll just invest in a couple of stride rites if it means I have a happy toddler with happy feet.

If only the cosmetic laces would not break and fray.
Size: 6 Toddler, Color: Navy
As in other reviews I saw, the lace (cosmetic) on one broke off from the shoe after only a few times worn and so does not look nice. Frustrating because the shoes are great for walking/running/ playing. 🤷🏼‍♀️

Perfect footwear! Wow...
Size: 9 Toddler, Color: Navy
Stride Rite deserves all the hype... The best children's shoes we have ever owned. I love the removable insert that lets you measure the foot, or adapt for wide / narrow feet. We took it out just to prevent extra pressure on the bone structure. Basically, I bought one pair of these, and one lower quality brand just for playtime / getting dirty, etc. It was a great setup and it's nice to have two pairs of shoes available. He outgrew these and I got the next size up of the same style. That's a very good sign 👍
