In vitro models of mtRNA extrusion are established, and m6A-dependent modulation as a potential therapeutic target for mtRNA-driven inflammation is highlighted.
Emerging insights into PTM-mediated regulation of MAVS are summarized and broader implications for mitochondrial antiviral signaling are outlined, highlighting new avenues for therapeutic modulation of innate immunity and cell fate during viral infection.

The NLRP3 inflammasome is a cytoplasmic multiprotein complex that is activated under stress or infection conditions. It promotes the maturation of IL-1β by cleaving pro-Caspase-1, thereby playing a critical role in host innate immune responses. Various viruses can differentially activate NLRP3 through distinct mechanis...

Metazoan organisms employ an array of overlapping innate and adaptive immune mechanisms to defend against infection and prevent disease. Z-nucleic acid-binding protein (ZBP)1 (also denoted DAI or DLM1) has emerged as a key nucleic acid (NA) sensor within mammalian cells responding to stress, infection or inflammation....
Emerging evidence supports an organelle-centered view of ISG15 biology but indicates that validated covalent mechanisms remain confined to selected substrates and contexts.

The mitochondrial antiviral signaling protein (MAVS; also known as VISA, IPS-1, or Cardif) is the central adaptor of the RIG-I-like receptor (RLR) pathway. Upon viral infection, MAVS forms prion-like aggregates to activate NF-κB and IRF3, thereby inducing type I interferon production and antiviral responses. Here, we i...

The analysis of human TB transcriptomic datasets showed that TRIM21 expression levels correlate with TB progression in human patients and demonstrated that TRIM21 deficiency suppresses Mtb growth in both macrophages and a murine model of tuberculosis (TB).
