abstractText | Innate immune detection of nucleic acids is important for initiation of antiviral responses. Detection of intracellular DNA activates STING-dependent type I interferons (IFNs) and the ASC-dependent inflammasome. Certain members of the AIM2-like receptor (ALR) gene family contribute to each of these pathways, but most ALRs remain uncharacterized. Here, we identify five novel murine ALRs and perform a phylogenetic analysis of mammalian ALRs, revealing a remarkable diversification of these receptors among mammals. We characterize the expression, localization, and functions of the murine and human ALRs and identify novel activators of STING-dependent IFNs and the ASC-dependent inflammasome. These findings validate ALRs as key activators of the antiviral response and provide an evolutionary and functional framework for understanding their roles in innate immunity. |
