HIV: reprogramming cells to control infection
Cells from the rare individuals who naturally control HIV infection have been the focus of investigation for nearly 15 years with the aim of elucidating their specific features. Following research on the ANRS CO21 CODEX and CO6 PRIMO cohorts, scientists from the Institut Pasteur have described the characteristics of CD8 immune cells in these "HIV controller" subjects. The unique antiviral power...

Immature heart cells persist in the adult heart and react to infarction
Cardiovascular diseases are a major cause of mortality and morbidity worldwide. After myocardial infarction, heart cells (or cardiomyocytes) die and are replaced by fibrotic tissue leading to impaired cardiac function. The assessment of the regenerative capacity of the heart has always been compromised by the lack of signatures to characterize cardiomyocytes. Researchers from the Institut Pasteur...

Shedding light on almost indestructible archaeal pili
Extremophiles are organisms that have evolved to thrive under extremely harsh environmental conditions. Scientists have always been mystified by how these organisms survive in such settings and especially how extracellular appendages, such as pili, remain stable. Researchers from the Institut Pasteur, in collaboration with colleagues from the University of Virginia revealed how sugars make those...

A fast likelihood method to reconstruct and visualize ancestral scenarios
The Institut Pasteur is at the forefront of computational biology research. Scientists in the Evolutionary Bioinformatics Unit (part of Institut Pasteur and CNRS Unit, USR 3756) recently developed the PastML program. This tool, based on decision-theory concepts, infers "ancestral scenarios" that describe the evolution of traits or characters along phylogenetic trees. The characters can be very...

Wolbachia, bacteria to combat dengue
The first mosquitoes carrying Wolbachia, bacteria that prevent them from transmitting arboviruses (including dengue, Zika and chikungunya), were released on Wednesday July 10, 2019 in Nouméa, New Caledonia, as part of the World Mosquito Program,* which involves teams from the Institut Pasteur de Nouvelle-Calédonie. The aim of this program is to encourage mosquitoes infected with Wolbachia to...

French Bioethics Law: an original participatory approach for the National Bioethics Consultation
A bioethics bill was tabled at the French Council of Ministers on Wednesday July 24, 2019. As the bill is examined by the French Parliament in September, it is a good opportunity to look at how this process came about and examine the contribution made by the French National Consultative Ethics Committee (CCNE). The CCNE Chairman, Professor Jean-François Delfraissy, came to the Institut Pasteur on...

Whooping cough: elucidation of a critical stage in the action of the CyaA toxin
Scientists from the Institut Pasteur are investigating CyaA, one of the major toxins of Bordetella pertussis. This bacterium is responsible for whooping cough, a disease that is currently on the rise. Acylation is a biochemical reaction in which an acyl chain is added to a molecule. It was already known that the CyaA protein was acylated in Bordetella pertussis. The scientists used a combination...
