Mitochondria play critical roles in intrinsic apoptosis and NLRP3 inflammasome activation, but how these processes are interconnected remains unclear. In this issue of Immunity, Saller et al. unveiled the complexity of NLRP3 activators, highlighting mitochondria's roles in switching apoptosis to NLRP3 inflammasome activation.

Mitochondrial dysfunction plays a pivotal role in the progression of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Alzheimer's, and Parkinson's disease. Recent discoveries have highlighted the involvement of DNA damage and repair processes, particularly mitochondrial DNA (mtDNA) damage, in these conditions. This commentary reflects on our recent findings, demonstrating the RNA/DNA binding protein fused in sarcoma (FUS)'s crucial role in maintaining mtDNA integrity through interactions with mitochondrial DNA ligase IIIα (mtLig3).

Primary mitochondrial disease (MD) is a group of rare genetic diseases reported to have a prevalence of 1:5000 and is currently without a cure. This group of diseases includes mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), maternally inherited diabetes and deafness (MIDD), Leber's hereditary optic neuropathy (LHON), Leigh syndrome (LS), Kearns-Sayre syndrome (KSS), and myoclonic epilepsy and ragged-red fiber disease (MERRF). Additionally, secondary mitochondrial dysfunction has been implicated in the most common current causes of mortality and morbidity, including cardiovascular disease (CVD) and cancer.
