Background

Signal-regulatory protein alpha (SIRPα, also known as CD172a or SHPS-1) is a type I transmembrane glycoprotein of the immunoglobulin superfamily, prominently expressed on myeloid cells, neurons, and stem cells, that functions as an inhibitory receptor by binding to the broadly expressed ligand CD47 (the “don’t eat me” signal) to negatively regulate innate immune effector functions such as macrophage phagocytosis of healthy host cells; upon CD47 engagement, phosphorylation of its cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs) recruits phosphatases like SHP-1 and SHP-2, thereby blocking actin cytoskeleton remodeling required for phagocytic activity, while structural studies have revealed its extracellular region contains three Ig-like domains (one V-set and two C1-set) and the interaction surface resembles antigen-receptor binding; in cancer, tumor cells exploit this CD47-SIRPα axis as an innate immune checkpoint to evade phagocytosis, making SIRPα a promising therapeutic target, especially in combination with anti-PD-1/PD-L1 therapies .

A lot of quality filters for little cost.
Style: 16x20x1, Style: 16x20x1
Been using these for months, great quality. No issues what so ever. I compared price to the 2 main big box stores and this is the best for your bucks. You get a lot more and they are of the same quality. I used to get mine from a big box store with military discount of 10% and this is still a better deal. They fit exactly like the filter I took out, so size is the same. I live FL and run my AC constantly. These last about 2-3 months each. They do no lose their rigidity. They are built with very high quality material. They catch a lot of dust, you can see how dirty they are when replaced. PROS - great quality and last 2-3 months in my AC running constantly - you get a lot for your money when compared to the big box stores - catch a lot of dirt, filters are really dirty after use - very rigid which makes it easy to installation - reinforced wire mesh CONS - None
