Background

Human butyrophilin subfamily 3 member A (BTN3A), also known as CD277, includes isoforms BTN3A1, BTN3A2, and BTN3A3 and is structurally associated with B7 costimulatory molecules. Each BTN3A isoform consists of an extracellular N-terminal Ig variable (V) domain and a near-membrane Ig constant (C) region connected to a single transmembrane domain. BTN3A family members have emerged as important molecules modulating the function of Vγ9Vδ2 T cells. The B30.2 intracellular domain plays an important role in this process. Only the intracellular B30.2 domain of BTN3A1 directly binds phosphorylated antigens (pAgs) through a positively charged pocket to activate Vγ9Vδ2 T cells. BTN3A1 is expressed in many tumors, such as ovarian cancer, bladder cancer, breast cancer, renal cell carcinoma and pancreatic ductal adenocarcinoma. The prognostic role of BTN3A1 in different cancers varies substantially.

Great play and chew toy!
Pattern Name: Star
The dogs love these! They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.

Great Dane Tested and Approved 5 Star
Pattern Name: Checkered, Pattern Name: Checkered
A picture is worth a thousand words applies to this product, as you will see in the attached photos these stand up to the abuse of a Great Dane. He has dragged me around the yard for hours already with this in his mouth and the stretchy handle keeps it shape. This ball is a little firmer than others of these I have had in the past, which helps exercise his giant jaw. I could get a few weeks out of the other brands I have bought. This brand is still like new well past the time others have failed. I will be ordering more as my French Mastiff is interested in one of his own (the boys do not like to share toys - most dog guardians understand).

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
