Even at Low Doses, Exposure to the Endocrine Disruptor DEHP Impairs Tooth Development

Some endocrine disruptors have already been associated with an impaired quality of tooth enamel. After demonstrating the harmful effects of bisphenol A on tooth development, a team of researchers from Inserm, Université Paris Cité and Sorbonne Université, at the Cordeliers Research Center in Paris, in collaboration with CNRS went on to look at the effects of DEHP, an endocrine disruptor in the phthalate family, on dental development.

One in Four French Adults Thought to Have Some Form of Hearing Loss

A new study shows for the first time that 25% of adults in France are affected by some form of hearing loss. Disabling hearing loss, which is more severe, is thought to affect 4% of adults. This prevalence varies with age and other factors (standard of living, noise exposure at work, cardiovascular diseases, etc.), which are described in the study. The scientists have found that hearing aids remain largely underused, especially among seniors.

Troubles du spectre de l’autisme : où en est la recherche ?

Les trouble du spectre de l’autisme (TSA) résultent de particularités du neuro-développement. Ils apparaissent au cours de la petite enfance et persistent à l’âge adulte. Environ 700 000 personnes en France seraient concernées. Dans les laboratoires de recherche, les efforts se poursuivent, non seulement pour identifier de nouvelles options thérapeutiques mais aussi pour améliorer le repérage précoce des TSA et leur prise en charge psychosociale tout au long de la vie.

Phage Therapy: A Model to Predict Its Efficacy against Pathogenic Bacteria

While bacteriophages – viruses that kill bacteria – could be a solution for fighting antibiotic-resistant pathogens, various obstacles stand in the way of their clinical development. To overcome them, researchers have developed a model to better predict the efficacy of phage therapy and possibly develop more robust clinical trials.

Signature d’un accord cadre entre Santé publique France et l’Inserm

Accord cadre Inserm SPF

Santé publique France et l’Inserm (Institut national de la santé et de la recherche médicale) signent aujourd’hui un accord visant à encadrer, renforcer et développer leur collaboration. Plusieurs thématiques prioritaires ont été identifiées pour les 5 prochaines années : maladies infectieuses émergentes et modélisation, facteurs environnementaux et santé, nutrition, inégalités sociales et santé périnatale. Cet accord permettra une alliance scientifique renforcée de la recherche avec la surveillance et la prévention-promotion de la santé, en appui aux décisions publiques.

Influenza: A New Avenue for Developing Innovative Treatments

Seasonal influenza is a major public health issue because it continues to remain associated with considerable mortality, particularly among people who are elderly, immunocompromised, or both. With vaccination and current treatments still being of limited efficacy, research teams are trying to develop new therapeutic approaches. Scientists have shown that in a context of influenza infection, a metabolite called succinate, which is naturally present in the body, has an antiviral and anti-inflammatory action. These findings open up new therapeutic prospects based on the use of succinate derivatives.

Infertility: New Avenues to Understand the Harmful Effects of Chemotherapy

In a new study, researchers investigated a receptor found on male germ cells that produce gametes, their aim being to find out more about its role in chemotherapy-related infertility. Their findings pave the way for a better understanding of male infertility and the development of treatments to reduce the risk of sterility from chemotherapy.

Long COVID: When Symptoms Persist Months after the First Wave

Dans une nouvelle étude, des scientifiques ont identifié, à partir des données de près de 26 000 volontaires de la cohorte Constances, quels symptômes persistants sont le plus fréquemment rapportés par les personnes ayant été infectées par le SARS-CoV-2 comparé au reste de la population. Il s’agit principalement de la perte de goût ou d’odorat, de gêne respiratoire ou de fatigue.

Production de nanoparticules délétères pour l’hôte par les bactéries responsables de sepsis

De récents résultats montrent que dans la lutte contre le sepsis, il ne faut pas seulement tuer les bactéries en cause, mais réduire aussi leur capacité à produire des vésicules de quelques dizaines de nanomètres (appelées OMV pour Outer Membrane Vesicle en anglais). Pour cela, il faut agir directement en amont sur les mécanismes de production de ces nanoparticules et/ou en développant des stratégies thérapeutiques pour les éliminer. L’équipe a en effet montré que ces OMV sont très délétères pour l’hôte, et pourraient favoriser l’aggravation du sepsis.

HIV: The Antibodies of “Post-treatment Controllers”

VIH

A very small percentage of people with HIV-1, known as “post-treatment controllers” (PTCs), are able to control their infection after interrupting all antiretroviral therapy. Understanding the fundamental mechanisms that govern their immune response is essential in order to develop HIV-1 vaccines, novel therapeutic strategies to achieve remission, or both. A recent study investigated the humoral immune response – also known as antibody-mediated immunity – in some PTCs in whom transient episodes of viral activity were observed. The researchers have shown their humoral immune response to be both effective and robust, which could help to control the infection in the absence of treatment.
