Gut inflammation occurring in patients with inflammatory bowel diseases (IBD) is associated with an excessive immune response that is directed against constituents of the normal bacterial flora and results in the production of large amounts of inflammatory cytokines. Anti-cytokine compounds, such as the neutralizing TNF antibodies, have been employed with clinical success in patients with IBD. However, nearly half of IBD patients are refractory to such treatments, response can wane with time, and anti-TNF treatment can associate with severe side effects and/or development/exacerbation of extra-intestinal immune-mediated pathologies. These observations, and the demonstration that, in IBD, the pathological process is also characterized by defects in the production and/or activity of counter-regulatory cytokines, have boosted further studies aimed at delineating novel strategies to combat the IBD-associated tissue-damaging immune response.
肠道炎症发生在炎症性肠病(IBD)患者中,与针对正常细菌菌群成分的过度免疫反应有关,导致大量炎症细胞因子的产生。抗细胞因子化合物,如中和 TNF 的抗体,在 IBD 患者中已成功应用于临床。然而,近一半的 IBD 患者对此类治疗有抗性,随着时间的推移,反应可能会减弱,抗 TNF 治疗可能会与严重的副作用和/或肠道外免疫介导的病理的发展/恶化相关。这些观察结果,以及在 IBD 中,病理过程还表现为产生和/或调节细胞因子的活性缺陷的证明,促使进一步研究旨在制定新的策略来对抗与 IBD 相关的组织损伤性免疫反应。
