{"product_id":"tnf-cgs-gfm31-20","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":"20 μg","offer_id":49304315724032,"sku":"CGS-GFM31-20","price":377.22,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/6591\/5392\/files\/GFM31_1_140512ae-11ac-48cb-859e-88a1b98473e3.jpg?v=1787291093","url":"https:\/\/shop.customscience.co.nz\/products\/tnf-cgs-gfm31-20","provider":"Custom Science Ltd","version":"1.0","type":"link"}
