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.

Perfect case for my daughter’s iPad
Color: Purple Pink
bought this case for my daughter. The fit is perfect — all the buttons and camera line up exactly and it snaps on securely. The case feels sturdy, protective, and durable but not too heavy, so she can still carry it comfortably. The stand feature is convenient. The design is also super cute — Luna loves it Overall, great quality for the price. I would definitely buy it again

Perfect case
Color: Purple Pink
Great protection for my IPad. I’m always dropping something. This case was pretty easy to install and has the protection over the glass front. No problem using the iPad with the cover. Cute colors and has a loop to store the pen
