In a new study, researchers have revealed a phenomenon of programmed cell death known as "apoptosis" that would explain the loss of lymphocytes in these patients.
Why are children less susceptible than adults to critical forms of COVID-19? A number of interesting avenues are emerging, notably suggesting differences in immune response following SARS-CoV-2 infection. In a new study, researchers have shown that the interferon response, which is part of the innate immune response, differs according to the age of the patient.
The French health authorities recommend that all adults over 18 years of age perform a booster injection with a MRNA to ensure maximum and prolonged vaccine protection. The COVIBOOST trial is designed to study the immune response of the two candidates based recombinant protein vaccine associated with an adjuvant developed by Sanofi Pasteur and GSK and that of a 3 rd dose of the Pfizer-Biontech vaccine.
Le 19 octobre, les représentants de dix établissements, dont l'Inserm, membres du Groupement d’intérêt scientifique (GIS) de l’Observatoire épidémiologique dans les eaux usées (Obépine), se sont réunis pour la première fois.
La pandémie de Covid-19 s’est accompagnée d’une dégradation de l’état de santé mentale d’une grande partie de la population française. Des chercheurs montrent que les étudiants sont particulièrement vulnérables. Pendant les deux premiers confinements, les prévalences des troubles anxieux et dépressifs, ainsi que des pensées suicidaires, étaient plus élevées dans cette population en comparaison à des non étudiants. Ces résultats, mettent en lumière la nécessité d’une grande vigilance en...
What are the molecular and genetic characteristics that distinguish patients with critical forms of COVID-19 – and particularly acute respiratory distress syndrome (ARDS)? Researchers have investigated the biological and genomic data of a targeted cohort of young patients. Patients hospitalized in intensive care with ARDS were compared with COVID-19 patients hospitalized in a non-critical care ward. As part of a Franco-US collaboration, the scientists have succeeded in identifying a...
What if a few minutes of interaction with a chatbot could effectively address vaccine concerns? In an article published in the Journal of Experimental Psychology: Applied (28 October 2021), researchers from the CNRS, INSERM, and ENS-PSL show that such an interface is indeed capable of swaying the vaccine-hesitant.
A large number of researchers are currently mobilized to increase knowledge of SARS-CoV-2 in order to improve the treatment of infected patients and try to predict the future health impacts of infection with the virus. Researchers have been the first to identify a direct effect of SARS-CoV-2 on the brain’s blood vessels.
Teams of researchers published on October 4, 2021 in the journal Molecular Psychiatry (Nature Publishing Group) a summary of the results of the international literature on the central role that “ ceramides ”, a class of lipids, may play a role in SARS-CoV-2 infection.
Teams of researchers measured the antibody and cellular responses generated by a messenger RNA vaccine in patients with systemic lupus (LS). This work shows that vaccination is both well tolerated and effective, even against worrying variants. The factors associated with a poor vaccine response in some of these patients have been identified in order to better anticipate who should benefit from reinforced protective measures and / or adapted...
