NLRP13 is a member of the NLR family pyrin domain containing proteins that functions as an inflammasome component involved in innate immune responses and inflammatory regulation 1. The protein localizes to the cytoplasm and participates in regulation of inflammatory responses through inflammasome complex formation 1. NLRP13 expression is upregulated during Toxoplasma gondii infection in THP-1 macrophages, contributing to IL-1β production and inflammasome activation 1. The gene is subject to epigenetic regulation through DNA methylation, with hypermethylation leading to gene silencing in familial Mediterranean fever patients, where it may influence disease severity 2. NLRP13 expression is elevated in brain tissues of Alzheimer's disease patients, particularly in hippocampal and frontal cortex regions, suggesting involvement in neuroinflammation 3. Additionally, NLRP13 has been identified as a prognostic marker in lung adenocarcinoma, where its expression is regulated by promoter methylation 4. Lower NLRP13 expression levels have been associated with mortality in HIV-tuberculosis co-infected patients 5. These findings indicate NLRP13 plays important roles in multiple inflammatory and pathological conditions through inflammasome-mediated immune responses.
