Background

Siglec-15 is a critical immune suppressor with broad upregulation on various cancer types and a potential target for cancer immunotherapy. Siglec-15 has unique molecular features compared with many other known checkpoint inhibitory ligands. It shows prominent expression on macrophages and cancer cells and a mutually exclusive expression with PD-L1. As a new player in the cancer immunotherapeutic arena, Siglec-15 may represent a novel class of immune inhibitors with tumor-associated expression and divergent mechanisms of action to PD-L1, with potential implications in anti-PD-1/PD-L1-resistant patients. Siglecs are cell surface proteins that bind sialic acid. They are found primarily on the surface of immune cells and are a subset of the I-type lectins. Siglec-15 consisting of immunoglobulin (Ig)-like domains, transmembrane domain and a short cytoplasmic tail. Siglec-15 is that recognizes sialylated glycans and regulates osteoclast differentiation. Siglec-15 is a potential therapeutic target for osteoporosis and plays a conserved regulatory role in the immune system of vertebrates.

Great value and super convenient for everyday use!
Size: 300 Count
exactly what I needed for busy days and quick cleanups. They’re sturdy enough for everyday meals like sandwiches, snacks, and even lighter hot foods without getting soggy or falling apart. I love the convenience of having such a large pack on hand — it lasts a long time and is perfect for families, parties, or meal prep days. The size is just right for most meals, and they stack easily for storage. For the price and quantity, it’s a great deal and saves so much time on dishwashing. Definitely a household staple I keep restocking!

Repeat buy for us!
This cocoa butter has become a staple in our household. Skin types range from extremely dry to somewhat "normal" yet we've found this product to be moisturizing for all. The soft scent of cocoa butter is not overwhelming at all and the texture is a bit thicker which is definitely helpful to moisturize during our dry and colder months in Minnesota.
