Identifying Inflammasome Activation in Human Tissues.

The NACHT, LRR, and PYD domain-containing protein-3 (NLRP3) inflammasome activation is part of a stereotyped cellular response to injury or infection. The NLRP3 inflammasome activation promotes cellular dysfunction and death, leading to local and systemic inflammation, organ dysfunction, and adverse outcome. Immunohistochemistry and immunofluorescence can be used to determine whether the NLRP3 inflammasome components are present in human biopsy or autopsy tissue samples.
