Background

V-set domain-containing T-cell activation inhibitor 1 (VTCN1) is also known as Immune costimulatory protein B7-H4, Protein B7S1, T-cell costimulatory molecule B7x, B7H4, which belongs to the immunoglobulin superfamily and BTN/MOG family. VTCN1 contains two Ig-like V-type (immunoglobulin-like) domains. The expression of VTCN1 is up-regulated by IL6 and IL10 and is inhibited by GM-CSF and IL4 on antigen-presenting cells (APCs). VTCN1/B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. VTCN1 involved in promoting epithelial cell transformation.

Well that didn't last long!
Color: Blue Puppy, Size: Medium Size 2
He loved it for the 15 minutes it took to destroy it! Cute design, but the material was thin enough to penetrate with his teeth and it was all over in a very short time! He still carries the carcass around and tries to play with it...it's sad. Definitely not for strong chewers.

Decent ball
Color: Blue Puppy, Size: Medium Size 2
Context: I have a busy, anxious Corgi. I like that it came with a pump to air it up. My dog likes the tag feature on it which made the ball easy to carry. She chewed off the tags pretty quick. She didn’t like herding this one as much. She prefers herding a basketball over this ball. The ball sits in the backyard through all the weather and elements and has held up pretty well. We’ve had it about a year and it’s still a good toy.

Easily Ripped apart within minutes
Color: Blue Puppy, Size: Medium Size 2, Color: Blue Puppy, Size: Medium Size 2
I have a new foster who’s only 35 pounds not an aggressive chewer and loves to play with my dogs rooster soccer ball toy but the ball itself is a little big for her to get her teeny little mouth around when she’s trying to carry and run with it this happened to pop up on my feed a size smaller (medium, instead of large ) and available for next day delivery, so I bought it specifically for the little dog to play with. I gave it to her to play outside while my hound is busy playing with one of her toys I went about watering the garden, when I turned around a few minutes later, I saw the ball appeared to be completely flattened. As I walked over, I saw pieces of black rubber on the ground, and then the rest of the ball had a gaping hole in it. The rooster version of the ball that I bought from another seller has been going strong for months with multiple dogs playing with it and chewing on it and ripping the side ribbons apart so either I got a defective toy or the quality of manufacturer from this seller is much lower since the durability of the ball seems to be less than an hour.

Not very durable
Color: Blue Puppy, Size: Medium Size 2
This ball is cute and my dog loves tags. However he popped this ball with one bite to carry it…. Within 10 minutes of getting it. It should have a tougher exterior
