Infliximab is a chimeric monoclonal IgG1 antibody that specifically binds to TNF-α. Infliximab prevents the interaction of TNF-α with TNF-α receptor (TNFR1 and TNFR2). Infliximab has the potential for autoimmune, chronic inflammatory diseases and diabetic neuropathy research[1][2]. So, infliximab is a medication used to treat patients with autoimmune and chronic inflammatory diseases[5].
infliximab has been also shown to improve insulin resistance[3]. In vitro,infliximab ameliorates TNF-alpha-induced insulin resistance in 3T3L1 adipocytes in vitro by restoring phosphorylation of key mediators of the insulin signaling pathway such as IRS-2 and AKT via PTP1B inhibition that in consequence improves insulin-dependent glucose uptake in these adipose cells[4]
Diabetic mice showed significant impairments in SNCV and MNCV at 8 weeks. Diabetic mice treated with saline showed no improvement in SNCV or MNCV at 12 weeks, whereas diabetic mice treated with infliximab showed significant improvement at this time (4 weeks after infliximab treatment). In conclusion a single injection of infliximab leads to marked improvement in diabetic neuropathy[7].Infliximab reduces the levels of serum insulin, fasting glucose and insulin resistance in patients with ankylosing spondylitis and rheumatoid arthritis[6]

英夫利昔单抗是一种嵌合单克隆 IgG1 抗体,可特异性结合 TNF-α。英夫利昔单抗阻止 TNF-α 与 TNF-α 受体（TNFR1 和 TNFR2）的相互作用。英夫利昔单抗具有用于自身免疫、慢性炎症性疾病和糖尿病神经病变研究的潜力[1][2]。因此,英夫利昔单抗是一种用于治疗自身免疫性疾病和慢性炎症性疾病的药物[5]。
英夫利昔单抗也被证明可以改善胰岛素抵抗[3]。在体外,英夫利昔单抗通过 PTP1B 抑制恢复胰岛素信号通路关键介质（如 IRS-2 和 AKT）的磷酸化,从而改善这些脂肪细胞中胰岛素依赖性葡萄糖摄取,从而改善 3T3L1 脂肪细胞中 TNF-α 诱导的胰岛素抵抗细胞[4]
糖尿病小鼠在 8 周时显示 SNCV 和 MNCV 显着受损。用盐水治疗的糖尿病小鼠在 12 周时未显示 SNCV 或 MNCV 改善,而用英夫利昔单抗治疗的糖尿病小鼠此时显示出显着改善（英夫利昔单抗治疗后 4 周）。总之,单次注射英夫利昔单抗可显着改善糖尿病神经病变[7]。英夫利昔单抗可降低强直性脊柱炎和类风湿性关节炎患者的血清胰岛素、空腹血糖和胰岛素抵抗水平[ 6]
