Background

B7 homolog 3 (B7-H3, CD276) is a member of the B7 family of cell surface ligands that regulate T cell activation and immune responses. B7-H3 protein contains two extracellular Ig-like V-type domains and two IgG-like C2-type domains, a transmembrane domain, and a short intracellular domain. Early research examining the biological process of B7-H3 suggested that B7-H3 is a positive regulator of T cell response. Subsequent research studies indicated that B7-H3 is a negative regulator of T cell response, and that the protein inhibits T cell proliferation. One possibility is that B7-H3 interacts with two distinct sets of receptors, resulting in seemingly opposite biological outcomes. B7-H3 is expressed by antigen presenting cells, activated T cells, and a few normal tissues, including placenta and prostate. Expression of B7-H3 is seen in several cancer types, including prostate, breast, colon, lung, and gastric cancers, and in endothelial cells from tumor associated vasculature

A favorite
Size: 7 Fl Oz (Pack of 1), Style: SPF 30
This is our go-to sunscreen. It has an 2020 EWG (ewg.org) safety rating of 3 (where a 1 is safest but often difficult to find and often too expensive and a 10 is the worst safety rating). We love that is not too thin or thick, so it goes on easily, and it works into your skin without leaving you white or greasy, has a neutral pleasant smell, stays on well in the water (up to 80 minutes), and is accessible (has a decent price around $1 per ounce and is easy to find in many local grocery and drug stores). It is the one my kids grab out of the pile every time! And the only reason there is a pile is that I am trying to find a sunscreen rated 1 or 2 by EWG that has all of the properties of Coppertone SPORT 30. The search continues....

Doesn’t come of from sweat or water
Size: 7 Fl Oz (Pack of 2), Style: SPF 30
The only sunscreen I use. Doesn’t burn eyes, doesn’t come off in the water or from sweat. Wish it came in SPF 20.
