Alternative names for M-CSF include CSF-1 and colony-stimulating factor 1. The M-CSF protein has a molecular mass of approximately 18 to 22 kDa. M-CSF is mainly expressed in various tissues including the placenta kidney and bone marrow. It functions as a homodimer important for the survival proliferation and differentiation of mononuclear phagocyte lineage cells.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nM-CSF influences the production differentiation and function of macrophages and osteoclasts. It is not part of a large complex but interacts with its receptor the CSF1R (colony-stimulating factor 1 receptor) on the surface of target cells. This interaction promotes the survival and proliferation of the target cells playing significant roles in immune response and bone homeostasis by regulating osteoclast development.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe interaction of M-CSF with its receptor is central to several biological pathways notably the immune system pathway and bone resorption pathway. Within these pathways the binding of M-CSF to CSF1R activates downstream signaling cascades such as the PI3K\/AKT and MAPK pathways importantly affecting cell survival and differentiation. The M-CSF pathway intersects with other cytokines and factors like GM-CSF (granulocyte-macrophage colony-stimulating factor) which also regulate immune cell dynamics.\u003cbr\u003e\nDysregulation of M-CSF levels is implicated in conditions such as osteoporosis and certain cancers. In osteoporosis M-CSF’s role in osteoclast development links to increased bone resorption leading to bone loss. In cancers M-CSF overexpression may facilitate tumor-associated macrophage infiltration therefore supporting tumor progression. The interaction with CSF1R is significant as it serves as a potential target for therapeutic strategies aimed at modulating macrophage activity in these diseases.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843857141929,"sku":"ab316075","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab316075","provider":"Iright","version":"1.0","type":"link"}
