07/2023 - Vaccine effectiveness for prevention of covid-19 related hospital admission during pregnancy in England during the alpha and delta variant dominant periods of the SARS-CoV-2 pandemic: population based cohort study
Objective: To estimate vaccine effectiveness for preventing covid-19 related hospital admission in individuals first infected with the SARS-CoV-2 virus during pregnancy compared with those of reproductive age who were not pregnant when first infected with the virus. Design: Population based cohort study. Setting: Office for National Statistics Public Health Data Asset linked dataset, providing national linked census and […]
06/2023 - DOT1L activity affects neural stem cell division mode and reduces differentiation and ASNS expression
Cortical neurogenesis depends on the balance between self-renewal and differentiation of apical progenitors (APs). Here, we study the epigenetic control of AP’s division mode by focusing on the enzymatic activity of the histone methyltransferase DOT1L. Combining lineage tracing with single-cell RNA sequencing of clonally related cells, we show at the cellular level that DOT1L inhibition […]
06/2023 - Modelling viral encephalitis caused by herpes simplex virus 1 infection in cerebral organoids
Herpes simplex encephalitis is a life-threatening disease of the central nervous system caused by herpes simplex viruses (HSVs). Following standard of care with antiviral acyclovir treatment, most patients still experience various neurological sequelae. Here we characterize HSV-1 infection of human brain organoids by combining single-cell RNA sequencing, electrophysiology and immunostaining. We observed strong perturbations of […]
05/2023 - Sites of transcription initiation drive mRNA isoform selection
The generation of distinct messenger RNA isoforms through alternative RNA processing modulates the expression and function of genes, often in a cell-type-specific manner. Here, we assess the regulatory relationships between transcription initiation, alternative splicing, and 3′ end site selection. Applying long-read sequencing to accurately represent even the longest transcripts from end to end, we quantify […]
05/2023 - High-resolution molecular atlas of a lung tumor in 3D
Cells live and interact in three-dimensional (3D) cellular neighborhoods. However, histology and spatial omics methods mostly focus on 2D tissue sections. Here we present a 3D spatial atlas of a routine clinical sample, an aggressive human lung carcinoma, by combining in situ quantification of 960 cancer-related genes across ∼340,000 cells with measurements of tissue-mechanical components. 3D cellular […]
