Analyzing caspase-1 activation during Legionella pneumophila infection in macrophages

Methods Mol Biol. 2013:954:479-91. doi: 10.1007/978-1-62703-161-5_29.

Abstract

Caspase-1 is a critical factor in the innate immune response to Legionella pneumophila. The development of methods for analyzing caspase-1 activation pathways and downstream caspase-1-associated activities has helped in understanding the regulation of this protease and the signaling components involved. Here we outline methods for directly detecting active caspase-1, measuring caspase-1 activities and analyzing components involved in the regulation of caspase-1 during L. pneumophila infection in macrophages.
