Leishmania : a parasite that adapts to its environment by chromosomal amplification
Leishmaniasis is an important human and veterinary disease caused by Leishmania parasites that affect 12 million people in over 98 endemic countries. The disease is now emerging in Europe due to climate change and massive population displacement. The parasite is known to rapidly adapt to novel environments with important consequences for disease outcome. It has therefore been recognized as an...

The factors that most affect our immune system
Why do we respond differently to infections or vaccines? Why are some people allergic to pollen? These are still unanswered questions in biological and medical science. The Milieu Intérieur Laboratory of Excellence coordinated at the Institut Pasteur by CNRS research director, Dr. Lluis Quintana-Murci, has recently described immune variation on a large scale within the French population. To...

COVID-19 pandemic: The Institut Pasteur International Network collective effort
To this day, SARS-CoV2, the virus responsible for COVID-19 pandemic, has been identified in more than 180 countries. It unfolded a once-in-a-century public health crisis, through his extensive impact on global economy directly caused by confinement measures. To confront these challenges, the 32 member institutes of the Institut Pasteur International Network (IPIN) are swinging into...

Small intestine regulates immune surveillance of colorectal cancer during chemotherapy treatment
An international study has demonstrated that the microbiota and the intestinal cell death triggered by chemotherapy stimulate the efficacy of the immune response in patients with colorectal cancer. The results of the study, conducted in France by scientists from Gustave Roussy, Inserm, Université Paris-Saclay, the Institut Pasteur, IHU Méditerranée Infection and INRAE, were published in the...

COVID-19: Identification of broadly SARS-CoV-2 neutralizing monoclonal antibodies
Although the different SARS-CoV-2 variants currently in circulation are undoubtedly less severe in vaccinated individuals in the general population, immunocompromised people are at greater risk of developing severe forms of COVID-19. Monoclonal antibodies currently offer the best approach, both as a preventive and curative treatment for these patients. Scientists from the Institut Pasteur and...

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...
