Background

CD40, also known as TNFRSF5 or Bp50, is a 48 kDa type I membrane glycoprotein belonging to the tumor necrosis factor receptor superfamily. It is widely expressed on various immune cells, including B cells, dendritic cells, and macrophages. The interaction between CD40 and its ligand, CD40L, is crucial for immune cell activation and regulation. Structurally, CD40 consists of a 62 amino acid cytoplasmic tail, a 22 amino acid transmembrane domain, and a 173 amino acid extracellular domain. This co-stimulatory protein plays a key role in B cell activation, proliferation, and differentiation, and is also involved in immune responses against infections and tumors. Due to its significant role in the immune system, CD40 has become an important therapeutic target, with various agonistic and antagonistic antibodies being developed to modulate its activity.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

Comfy pillow
Color: White-cooling Basic, Size: Standard(Pack of 1)
I love this pillow! It comes with extra stuffing so you can get the firmness how you like it. I’m a side sleeper so I need a pillow that is thick enough for me to be able to sleep on my side and this pillow does the job. It is pretty cool. I do get hot when I sleep and I’ve noticed a little bit of a difference. I also think it’s very comfortable to sleep with. Would recommend.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.
