Screening the Impact of Sirtuin Inhibitors on Inflammatory and Innate Immune Responses of Macrophages and in a Mouse Model of Endotoxic Shock

Methods Mol Biol. 2016:1436:313-34. doi: 10.1007/978-1-4939-3667-0_21.

Abstract

The development and screening of pharmacological modulators of histone deacetylases (HDACs), and particularly sirtuins, is a promising field for the identification of new drugs susceptible to be used for treatment strategies in a large array of welfare-associated, autoimmune and oncologic diseases. Here we describe a comprehensive protocol to evaluate the impact of sirtuin-targeting drugs on inflammatory and innate immune responses in vitro and in a preclinical mouse model of endotoxemia. We first provide an overview on strategies to design in vitro experiments, then focus on the analysis of cytokine production by primary macrophages and RAW 267.7 macrophages at the mRNA and protein levels, and finally describe the setup and follow-up of a mouse model of inflammation-driven endotoxic shock.
