项目摘要

 DESCRIPTION (provided by applicant): Emerging antibiotic resistance is a global health crisis. From broadly resistant "superbugs" to extremely drug resistant Mycobacterium tuberculosis (XDR-TB), the specter of untreatable bacterial infection has become an alarming reality. The problem has become so acute that President Barack Obama recently issued an executive order calling multidrug resistant bacteria a national security priority. Likewise, the need to develop better antibiotics that shorten the treatment time to cure persistent bacterial infections also remains a major goal, especially for some of the most notorious pathogens of man, including M. tuberculosis. Due to the slow rate of new antibiotics emerging from the lab, countering antibiotic resistance and persistence by modifying existing drugs or developing inhibitors to new bacterial targets is unlikely to keep up with the increasing demand. The goal of this project is to take a radically different approach to new antibiotic development by identifying small molecules that target powerful host immune pathways of innate immune cells, creating adjunctive therapies that will synergize with conventional antibiotics. This approach is antithetical to traditional antibiotic development programs, which seek to identify molecular inhibitors that target essential pathways of the bacterium but avoid host pathways. The potential impact of "Host-Directed Therapies" (HDTs) could be dramatic, as they may re-sensitize drug-resistant strains and shorten the time to eradicate chronic infections. In particular, this proposa seeks to translate our understanding of host-pathogen interactions into a novel program for identifying small molecules targeting host processes that will synergize with traditional antibiotics during TB infection. The implications of success may extend beyond bacterial infection, as this approach could have huge implications for a broad range of infectious agents, and even boost vaccine efficacy.
 描述(由申请人提供):新出现的抗生素耐药性是一场全球健康危机。从广泛耐药的“超级细菌”到极端耐药的结核分枝杆菌(XDR-TB),无法治愈的细菌感染的幽灵已成为令人震惊的现实。这个问题已经变得如此尖锐,以至于美国总统奥巴马最近发布了一项行政命令,将多药耐药细菌称为国家安全优先事项。同样,开发更好的抗生素以缩短治疗持续性细菌感染的时间也仍然是一个主要目标,特别是对于一些最臭名昭著的人类病原体,包括M。结核由于新抗生素从实验室中出现的速度缓慢,通过修改现有药物或开发针对新细菌靶标的抑制剂来对抗抗生素耐药性和持久性不太可能跟上不断增长的需求。该项目的目标是采取一种完全不同的方法来开发新的抗生素, 小分子靶向先天免疫细胞的强大宿主免疫途径,创造出与传统抗生素协同作用的免疫疗法。这种方法与传统的抗生素开发计划是对立的,传统的抗生素开发计划寻求识别靶向细菌的基本途径但避免宿主途径的分子抑制剂。“宿主导向疗法”(HDTs)的潜在影响可能是巨大的,因为它们可能使耐药菌株重新敏感,并缩短根除慢性感染的时间。特别是,该提案旨在将我们对宿主-病原体相互作用的理解转化为一种新的程序,用于识别靶向宿主过程的小分子,这些过程将在结核病感染期间与传统抗生素协同作用。成功的意义可能超越细菌感染,因为这种方法可能对广泛的感染因子产生巨大影响,甚至提高疫苗的效力。
