This protein has a molecular mass of approximately 8.4 kDa. Eotaxin is mainly expressed in epithelial cells fibroblasts and smooth muscle cells. High levels of expression occur during inflammatory processes where it acts as a chemoattractant guiding eosinophils to sites of inflammation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nEotaxin plays an important role in immune response regulation particularly in allergic reactions. It functions by binding to CCR3 a receptor found on eosinophils therefore facilitating their migration. This process includes involvement in the formation of protein complexes that modulate cell signaling. Eotaxin's primary biological role lies in promoting the accumulation of eosinophils which are important for the immune defense against parasitic infections.\u003cbr\u003e\nPathways\u003cbr\u003e\nEotaxin participates in the MAPK\/ERK signaling pathway which influences cell migration and proliferation. Additionally it operates within the NF-kB pathway often regulating inflammation and immune response. In these pathways eotaxin interacts with other proteins like CCR3 and IL-5 contributing to a coordinated response in immune signaling.\u003cbr\u003e\nEotaxin is closely linked to allergic asthma and atopic dermatitis. In both these conditions eotaxin-mediated eosinophil recruitment and activation worsen inflammation. Research shows significant eotaxin expression in asthmatic airway tissues. It also connects with proteins like IL-5 which amplify eosinophilic activity leading to exacerbated allergic responses.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843919892649,"sku":"ab243753","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab243753","provider":"Iright","version":"1.0","type":"link"}
