Background

B7-h3 (B7 homolog 3 protein), also known as CD276, is an important immune checkpoint molecule in the B7-CD28 family. It is a type I transmembrane glycoprotein consisting of 316 amino acids and contains a putative 28AA signal peptide, a 217AA extracellular region composed of immunoglobulin constant (IgC) and variable (IgV) structures, a transmembrane region, and a 45-amino acid cytoplasmic domain. B7-H3 is a T cell co-suppressor molecule with partial co-stimulatory function. B7-H3 can effectively inhibit the function of T cells and NK cells, and also play a role in bone development. The expression of B7-H3 is low in normal tissues and is found in a variety of malignant tumors, which is closely related to the growth, metastasis, recurrence and poor prognosis of malignant tumors. B7-H3 can down-regulate T-assisted type 1 mediated immune response, inhibit CD4+T cell activation and inhibit cytokine production, and thus may play a role in promoting immune escape of cancer cells.

Good Product, but images over promise just a little.
Color: Ripple Pattern
- Performs well on tile and low pile carpet. On artificial grass it doesn’t roll even on the highest setting; it only vibrates. Watch the video. - Still fun for my pup. I’ve only had it a day so no clue about durability although my dog is a strong chewer. - Price Value: When purchased it was 2 balls for the same price of a single ball from competitor. - Material feels like a Nerf football. Easy to disassemble and charge.

Best jiggle balls we have found thus far
Color: Ripple Pattern
Yes ! First off this was a great value for the money. The balls function just as described and they have a decent battery life. They entertain both our goldens for a good bit of time. They have so far held up and not been chewed up . We limit the time and put them away after that time.. to avoid them being destroyed. Of all the jiggle balls we have purchased these are by far the best. The way the component is encased in the rubber protects it.. and it screws together very well. I am so pleased with these !

Highly recommend for pet owners looking to keep their dogs busy and happy!
Color: Grid Pattern
These interactive dog toys were a great surprise! My dog was instantly interested in the bouncing and vibrating movement, and it kept him entertained much longer than regular toys. I like that the balls are rechargeable and washable, which makes them easy to maintain after outdoor play. The automatic motion is fun and unpredictable enough to keep pets curious and active. Great value for a 2-pack, especially for energetic dogs that need extra stimulation during the day. Highly recommend for pet owners looking to keep their dogs busy and happy!

This interactive dog toy ball is amazing! It moves and jumps automatically, which keeps my dog constantly engaged and excited. My dog loves chasing it around the house and never seems to get bored. The material feels very durable and holds up well even with strong chewing. It’s a great way to keep pets active and entertained. Definitely a fun and high-quality toy I would recommend!
