ADAR1 as a Placental Innate Immune Rheostat Sustaining the Homeostatic Balance of Intrinsic Interferon Response at the Maternal‐Fetal Interface
This study reveals that ADAR1, an RNA-editing enzyme, fine-tunes immune responses in the placenta by preventing the accumulation of immunogenic double-stranded RNAs (dsRNAs) from interferon-stimulate...

Une protéine humaine héritée des bactéries révèle un pan méconnu de notre immunité - Salle de presse de l'Inserm
Depuis quelques années, certains scientifiques explorent les liens inattendus entre les protéines humaines impliquées dans la défense de l’organisme et certains mécanismes immunitaires bactériens. C’e...

Dicer accumulates in cytoplasmic foci upon alphavirus infection and plays a proviral role in Myotis myotis bat cells
Bats are reservoirs for many viruses that frequently cause epidemics in humans and animals. It is thus critical to better understand their immune system and mechanisms of antiviral immunity. Despite a...

Fatty Acid Synthase binds endogenous dsRNAs and dampens the innate immune response to exogenous dsRNAs by limiting their accumulation.
In mammalian cells, the presence of double-stranded RNA (dsRNA) in the cytoplasm is a danger signal indicative of viral infection. Cells establish and maintain an antiviral state via the production of...

Bat organoids reveal antiviral responses at epithelial surfaces - Nature Immunology
Kellner et al. develop respiratory and intestinal organoids from Rousettus aegyptiacus to show elevated basal expression of interferon-ε (IFNε) and IFN-stimulated genes, along with robust, self-amplifying type III IFN responses that drive antiviral defense against zoonotic RNA viruses.
