Adenoviruses are infectious agents that replicate in humans and many animals, often causing no, or only mild, symptoms. Owing to their large genome size and overall stability, members of this virus family are used as viral vectors, for example in vaccines or cancer therapy.
Phase separation of the human adenovirus 52-kDa protein has an essential role in the formation of biomolecular condensates, regulating the coordinated assembly of viral progeny particles.
A retrospective analysis using PCR testing, viral enrichment-based sequencing and agnostic metagenomic sequencing finds an association between adeno-associated virus type 2 and paediatric hepatitis of unknown cause.
Neither CDK4/6 inhibitors nor oncolytic adenoviruses show high efficiency as monotherapy in the treatment of cancer. Authors show here that when combined, CDK4/6 inhibitors deplete Retinoblastoma protein levels, which leads to more efficient virus replication and an increase in oncolytic virus-producing cancer cells and thus to efficient anti-tumor response in mouse xenograft sarcoma models.
Base editing is promising for gene therapy, but in vivo delivery has been limiting. Here the authors perform structure-based rational engineering of the cytosine base editing system Target-AID to minimise off-target effects and decrease its size.
