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.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.
