DHX15 is required to control RNA virus-induced intestinal inflammation.

Cell Rep 2021 Jun;35(12):109205

Immunobiology and Transplant Science Center, Houston Methodist Research Institute, Houston, TX 77030, USA; Department of Surgery, Weill Cornell Medical College of Cornell University, New York, NY 10065, USA. Electronic address:

RNA helicases play critical roles in various biological processes, including serving as viral RNA sensors in innate immunity. Here, we find that RNA helicase DEAH-box helicase 15 (DHX15) is essential for type I interferon (IFN-I, IFN-β), type III IFN (IFN-λ3), and inflammasome-derived cytokine IL-18 production by intestinal epithelial cells (IECs) in response to poly I:C and RNA viruses with preference of enteric RNA viruses, but not DNA virus. Importantly, we generate IEC-specific Dhx15-knockout mice and demonstrate that DHX15 is required for controlling intestinal inflammation induced by enteric RNA virus rotavirus in suckling mice and reovirus in adult mice in vivo, which owes to impaired IFN-β, IFN-λ3, and IL-18 production in IECs from Dhx15-deficient mice.

High Th2 cytokine levels and upper airway inflammation in human inherited T-bet deficiency.

J Exp Med 2021 Aug 23;218(8). Epub 2021 Jun 23.

Institute of Microbiology, Eidgenössische Technische Hochschule Zurich, Zurich, Switzerland.

We have described a child suffering from Mendelian susceptibility to mycobacterial disease (MSMD) due to autosomal recessive, complete T-bet deficiency, which impairs IFN-γ production by innate and innate-like adaptive, but not mycobacterial-reactive purely adaptive, lymphocytes. Here, we explore the persistent upper airway inflammation (UAI) and blood eosinophilia of this patient. Unlike wild-type (WT) T-bet, the mutant form of T-bet from this patient did not inhibit the production of Th2 cytokines, including IL-4, IL-5, IL-9, and IL-13, when overexpressed in T helper 2 (Th2) cells.
