Understanding resistance in HIV controller patients: how their antiviral CD4+ T cells are protected from infection
Some rare HIV-infected patients are able to keep the viral load low enough not to require treatment. A study by researchers at the Pasteur Institute and collaborators shows that these patient CD4+ T cells block a receptor that is important for HIV entry.

Modeling: understanding how SARS-CoV-2 variants are selected
Several factors determine the evolutionary success of SARS-CoV-2 variants of concern. A recent publication looks into the factors influencing this success – the number of people that an individual with the virus infects in turn, the timing of these infections and the contact rate –, using mathematical modeling to help understand the characteristics of these variants.

COVID-19: reducing outbreak risk with repeated antigen screening in healthcare facilities
With the emergence of the Omicron variant, healthcare facilities remain highly vulnerable to virus spread. Effective surveillance of viral presence in these facilities is therefore crucial and needs to be adapted according to outbreak risk. Scientists from the Institut Pasteur worked with colleagues to analyze the reactive use of antigen testing in a long-term care facility following a detected...

Malaria and the globalization of disease
This 18 May 2022 is the centenary of the death of Alphonse Laveran, winner of the Nobel Prize for Medicine and discoverer of the protozoan responsible for malaria, which has caused hundreds of millions of deaths around the world since the dawn of humanity. Few diseases have left such a lasting legacy on the history and lives of humans as malaria. This parasitic disease, which tends to follow a...
