The following cells constitutively express class II MHC molecules and therefore act as so-called professional APCs: Dendritic cells Monocytes Macrophages B cells Dendritic cells are present in the skin (as Langerhans cells), lymph nodes, and tissues throughout the body. The innate immune system is essentially made up of barriers that aim to keep viruses, bacteria, parasites, and other foreign particles out of your body or limit their ability to spread and move throughout the body. Pores are formed in a pathogen membrane, causing it to lyse. This is how our immune system recognizes our own cells versus foreign bodies. b) they produce antibodies Alpha-fetoprotein(AFP) is a cancer biomarker for the diagnosis of hepatocellular carcinoma(HCC); however, its role in macrophage polarization and phagocytosis remains unclear.
