Background

CD4 is a glycoprotein expressed on the surface of certain immune cells, most notably helper T cells. It is a member of the immunoglobulin superfamily and has four immunoglobulin-like domains (D1 to D4). CD4 acts as a co-receptor with the T-cell receptor (TCR) to recognize antigens displayed by MHC class II molecules on antigen-presenting cells. The D1 domain of CD4 binds to the β2 region of MHC class II, bringing the TCR complex and CD4 into close proximity. This allows the tyrosine kinase Lck, bound to the cytoplasmic tail of CD4, to phosphorylate tyrosine residues on the cytoplasmic domains of CD3, amplifying the signal generated by the TCR. CD4 is also the primary receptor for the human immunodeficiency virus (HIV), and its interaction with the HIV gp120 protein is a key step in viral entry.

Not a strong toy for chewers.
Color: Yellow
Not quite as strong as its description. My dog chewed off its foot within the first 10 minutes . I expected it to be stronger because it’s made of Kevlar material but it’s not that durable. Save your money it is far from being durable / indestructible.

Leave a toy for the dog when going to work, and no housebreaking when coming back
Color: Purple-Blue, Size: 2pcs
The dog is quite clingy. Every time it sees me put on my shoes to go out, it gets nervous. Since having this bear around, when it goes out, its attention is all on the toys, and when it comes back home, its mood has become much more stable.

Keeps my dog busy and actually holds up
This jigsaw-style dog toy has been a game changer for keeping my dog entertained. The design is super versatile—you can spread peanut butter (or yogurt, wet food, etc.) into the grooves, and it keeps them busy licking for a long time. What I like most is that it’s not just a lick mat—it’s also a durable chew toy. The material feels strong and holds up really well, even with a dog that usually destroys toys pretty quickly. Toys made from rubber or similar materials tend to last longer and are safer for chewing compared to softer options. The grooves and compartments make it a little more challenging (in a good way), so it takes my dog longer to get through the treats. I’ve even tried freezing peanut butter inside, and that keeps them occupied even longer. Lick-style toys like this are great for slowing dogs down and keeping them calm and engaged. It’s also been really helpful during times when I need a distraction—like when I’m busy, cleaning, or even during grooming. Pros: • Durable and holds up to chewing • Can use peanut butter, yogurt, or other soft treats • Keeps dogs busy for a long time • Helps with boredom and anxiety • Freezable for longer use Cons: • Can get messy depending on what you put in it
