{"product_id":"tnf-cgs-gfr18-1000","title":"TNF-α","description":"\u003cp\u003eTumor Necrosis Factor α (TNF-α) is an inflammatory cytokine secreted by macrophages, monocytes, neutrophils, T cells, and Natural Killer (NK) cells following stimulation by bacterial lipopolysaccharide (LPS). TNF-α signal activation occurs through two receptors, TNFR1 and TNFR2. TNFR1 is expressed on most cell types, unlike TNFR2, which is expressed mainly on immune cells. TNF-α functions to stimulate phagocytosis in macrophages, chemoattract neutrophils, increase insulin resistance, and induce fever.\u003c\/p\u003e","brand":"Cell Guidance Systems","offers":[{"title":"1 mg","offer_id":49304315887872,"sku":"CGS-GFR18-1000","price":6768.32,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/6591\/5392\/files\/GFR18_1_0dfc4c46-11e6-4748-acc9-967f447c8c8d.jpg?v=1787291101","url":"https:\/\/shop.customscience.co.nz\/products\/tnf-cgs-gfr18-1000","provider":"Custom Science Ltd","version":"1.0","type":"link"}
