{"product_id":"tnf-af-cgs-gfh111af-500","title":"TNF-α (AF)","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":"500 μg","offer_id":49304315330816,"sku":"CGS-GFH111AF-500","price":1905.34,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/6591\/5392\/files\/GFH111_1_c78a0d3b-8c85-493d-a229-56f00b6c01d6.jpg?v=1787291076","url":"https:\/\/shop.customscience.co.nz\/products\/tnf-af-cgs-gfh111af-500","provider":"Custom Science Ltd","version":"1.0","type":"link"}
