Among the various aspects of the present disclosure is the provision of composition comprising itaconate, malonate, or a derivative thereof and uses thereof. The present disclosure provides for methods of treating Ikb-ζ associated disease, disorder, or conditions comprising administering a therapeutically effective amount of an itaconate, malonate, or a derivative thereof to a subject. In some embodiments, the therapeutically effective amount reduces or prevents tumor growth, inflammation, or an immune response. Another aspect of the present disclosure includes a method to suppress Ikb-ζ induction comprising administering an itaconate, malonate, or a derivative thereof.

effects of itaconate and DI on the inflammatory program has not been defined. Here we show that itaconate and DI induce electrophilic stress, react with glutathione and subsequently induce both Nrf2 (also known as NFE2L2)-dependent and -independent responses. We find that electrophilic stress can selectively regulate secondary, but not primary, transcriptional responses to toll-like receptor stimulation
代谢调节已被认为是指导免疫反应的强大原则。炎症巨噬细胞经历广泛的代谢重组1,其标志是产生大量衣康酸,最近被描述为一种免疫调节代谢物2。衣康酸酯及其可渗透膜的衍生物衣康酸二甲酯 (DI) 选择性抑制细胞因子 2 的子集,包括 IL-6 和 IL-12,但不抑制 TNF。衣康酸对巨噬细胞活化过程中细胞代谢的主要影响归因于对琥珀酸脱氢酶2,3的抑制,但仅这种抑制不足以解释在DI病例中观察到的显着免疫调节作用。此外,衣康酸和DI对炎症程序的这种选择性作用的调节途径尚未确定。在这里,我们表明衣康酸和 DI 诱导亲电应激,与谷胱甘肽反应,随后诱导 Nrf2(也称为 NFE2L2)依赖性和非依赖性反应。我们发现亲电应激可以通过抑制 IκB z 蛋白诱导选择性地调节对 Toll 样受体刺激的次级转录反应,但不能调节初级转录反应。 IκB z 的调节独立于 Nrf2,我们将 ATF3 确定为其关键介质。抑制
