The discovery of gasdermin D (GSDMD) as the terminal executioner of pyroptosis provided a large piece of the cell death puzzle, whilst simultaneously and firmly putting the gasdermin family into the limelight. In its purest form, GSDMD provides a connection between the innate alarm systems to an explosive, inflammatory form of cell death to jolt the local environment into immunological action. However, the gasdermin field has moved rapidly and significantly since the original seminal work and novel functions and mechanisms have been recently uncovered, particularly in response to infection. Gasdermins regulate and are regulated by mechanisms such as autophagy, metabolism and NETosis in fighting pathogen and protecting host. Importantly, activators and interactors of the other gasdermins, not just GSDMD, have been recently elucidated and have opened new avenues for gasdermin-based discovery. Key to this is the development of potent and specific tool molecules, so far a challenge for the field. Here we will cover some of these recently discovered areas in relation to bacterial infection before providing an overview of the pharmacological landscape and the challenges associated with targeting gasdermins.
gasdermin D(GSDMD)的发现作为细胞焦亡的最终执行者,为细胞死亡的谜题提供了一个重要的部分,同时也将 gasdermin 家族推向了聚光灯下。在最纯粹的形式中,GSDMD 将先天警报系统与一种爆炸式的、炎症性的细胞死亡形式联系起来,从而使局部环境迅速进入免疫反应。然而,自最初的开创性工作以来,gasdermin 领域已经迅速发展,并揭示了新的功能和机制,特别是在应对感染方面。gasdermins 通过自噬、代谢和 NETosis 等机制来调节和被调节,以对抗病原体并保护宿主。重要的是,gasdermin 的其他激活剂和相互作用因子,而不仅仅是 GSDMD,最近已经被阐明,并为基于 gasdermin 的发现开辟了新的途径。关键是开发有效的、特异性的工具分子,这到目前为止一直是该领域的一个挑战。在这里,我们将在提供靶向 gasdermins 相关的药理学概况和挑战之前,介绍一些与细菌感染相关的这些新发现的领域。
