SARS-CoV-2 escapes host immune responses by modulating dendritic cell maturation
A team of scientists from Italy and the USA has recently explored the maturation pattern of conventional dendritic cells (cDCs) during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Their findings reveal that the virus efficiently escapes host immune responses by directly interacting with cDCs and disrupting T cell activation. The study is currently available on the
Background
Since its emergence in December 2019 in China, SARS-CoV-2, the causative pathogen of coronavirus disease 2019 (COVID-19), has infected 114 million people and claimed 2.5 million lives worldwide. In its milder form, COVID-19 is mainly associated with fever, dry cough, sore throat etc. However, a severe form of the disease often leads to serious health complications characterized by cardiovascular, pulmonary, and metabolic disorders. In general, COVID-19 patients with severe symptoms exhibit severe immune
Abstract
Information about individual-level genetic ancestry is central to population genetics, forensics and genomic medicine. So far, studies have typically considered genetic ancestry on a broad continental level, and there is much less understanding of how more detailed genetic ancestry profiles can be generated and how accurate and reliable they are. Here, we assess these questions by developing a framework for individual-level ancestry estimation within a single European country, Finland, and we apply the framework to track changes in the fine-scale genetic structure throughout the 20
th century. We estimate the genetic ancestry for 18,463 individuals from the National FINRISK Study with respect to up to 10 genetically and geographically motivated Finnish reference groups and illustrate the annual changes in the fine-scale genetic structure over the decades from 1920s to 1980s for 12 geographic regions of Finland. We detected major changes after a sudden, internal migration r
Thanks to longer term trends in digitalisation, transparency and the urgent need for quick economic guidance in the pandemic, the pool of data for tracking economic activity in almost real time has grown significantly. Researchers and policy makers now have access to new and innovative data sets, the most known probably being Google mobility reports. .
