Article Synopsis
- Integrin alpha V is crucial for cell adhesion and signaling during development, and mutations in its gene (ITGAV) can lead to serious health issues.
- In three families, biallelic variants were found that caused either dysfunctional protein production or the integrin being misplaced, resulting in severe developmental problems like eye and brain abnormalities, inflammatory bowel disease, and immune issues.
- Studies in patient cells and zebrafish models confirmed these mutations resulted in impaired immune signaling and developmental defects, linking the ITGAV variants to a newly identified human disease.
Despite selective HDAC3 inhibition showing promise in a subset of lymphomas with CREBBP mutations, wild-type tumors generally exhibit resistance. Here, using unbiased genome-wide CRISPR screening, we identify GNAS knockout (KO) as a sensitizer of resistant lymphoma cells to HDAC3 inhibition. Mechanistically, GNAS KO-induced sensitization is independent of the canonical G-protein activities but unexpectedly mediated by viral mimicry-related interferon (IFN) responses, characterized by TBK1 and IRF3 activation, double-stranded RNA formation, and transposable element (TE) expression.

Here, we demonstrate that ICAM1 surface expression distinguishes extra- from intravascular neutrophils in the mouse CNS during experimental autoimmune encephalomyelitis (EAE). Transcriptomic analysis of these 2 subpopulations indicated that neutrophils, once extravasated, acquire macrophage-like properties, including the potential for immunostimulation and MHC class II-mediated antigen presentation.
