Abstract
AIM2 is an interferon-inducible HIN-200 protein family member and is well-documented for its roles in innate immune responses as a DNA sensor. Recent studies have highlighted AIM2's function on regulatory T cells (Treg) and follicular T cells (Tfh). However, its involvement in Th17 cell differentiation remains unclear. This study reveals that AIM2 promotes Th17 cell differentiation. AIM2 deficiency decreases IL-17A production and downregulates key Th17 associated proteins (RORγt, IL-1R1, IL-23R). AIM2 is located in the nucleus of Th17 cells, where it interacts with RORγt, enhancing its binding to the Il17a promoter. The absence of AIM2 hinders naive CD4 T cells from differentiating into functional Th17 cells and from inducing colitis in Rag1-/- mice. This study uncovers AIM2's role as a regulator of Th17 cell transcriptional programming, highlighting its potential as a therapeutic target for Th17 cell-mediated inflammatory diseases.

Abstract
Patients with severe COVID-19 develop acute respiratory distress syndrome (ARDS) that may progress to cytokine storm syndrome, organ dysfunction, and death. Considering that complement component 5a (C5a), through its cellular receptor C5aR1, has potent proinflammatory actions, and plays immunopathological roles in inflammatory diseases, we investigated whether C5a/C5aR1 pathway could be involved in COVID-19 pathophysiology. C5a/C5aR1 signaling increased locally in the lung, especially in neutrophils of critically ill COVID-19 patients compared to patients with influenza infection, as well as in the lung tissue of K18-hACE2 Tg mice (Tg mice) infected with SARS-CoV-2. Genetic and pharmacological inhibition of C5aR1 signaling ameliorated lung immunopathology in Tg-infected mice. Mechanistically, we found that C5aR1 signaling drives neutrophil extracellular trap (NET)s-dependent immunopathology. These data confirm the immunopathological role of C5a/C5aR1 signaling in COVID-19 and indicate that antagonists of C5aR1 could be useful for COVID-19 treatment.
