2025 seasonal flu: France in the grip of an epidemic
The influenza epidemic is officially under way in France, a little earlier than last year. Every year, the Institut Pasteur monitors respiratory viruses, including influenza. This season it is contributing new expertise, using modeling to forecast the peak of the 2025-2026 outbreak. It is always worth bearing in mind that although seasonal influenza is usually a mild disease, it can also be fatal...

Light shed on SARS-CoV-2 replication in bat cells
Bats are reservoir species for numerous viruses including coronaviruses. Given that they do not appear to be affected by diseases transmitted by these viruses, there is potential benefit in understanding how their immune system regulates infection. Scientists at the Institut Pasteur and the CNRS studied SARS-CoV-2 replication in bat cells, which involved using real-time imaging techniques for the...

Using paleogenomics to elucidate 10,000 years of immune system evolution
Scientists from the Institut Pasteur, Université Paris Cité, the CNRS and the Collège de France have used paleogenomics to trace 10,000 years of human immune system evolution. They analyzed the genomes of more than 2,800 individuals who lived in Europe over the past ten millennia. They were able to date the increase in frequency of most of the mutations that are advantageous in defending against...

New discovery concerning receptors used by coronaviruses to enter human cells
The SARS-CoV-2 virus responsible for COVID-19 can cause severe acute respiratory syndrome, contrasting with other coronaviruses that were known to cause mild seasonal colds prior to its emergence in 2019. This raises the question of why one coronavirus affects humans more severely than another. Scientists at the Institut Pasteur, Université Paris Cité and the VRI have now provided part of the...

The SARS-CoV-2 virus can migrate within neurons and infect the brain
The emergence of different variants of SARS-CoV-2 has produced a wide range of clinical profiles and symptoms in patients. For the first time, researchers at the Institut Pasteur and Université Paris Cité have demonstrated, in an animal model, a characteristic common to several SARS-CoV-2 variants: the ability to infect the central nervous system. The study confirms that SARS-CoV-2 is capable of...
