Lire les sons du langage : une aire du cerveau spécialisée dans la reconnaissance des graphèmes

Une étude a permis d’analyser les mécanismes de la lecture à l’œuvre chez les adultes. Les chercheurs ont identifié une région cérébrale du cortex visuel qui serait responsable de la reconnaissance des graphèmes, c’est-à-dire des lettres ou groupes de lettres transcrivant un son élémentaire de la langue parlée (phonèmes).

Assistance médicale à la procréation : la congélation embryonnaire associée à une augmentation du poids de naissance

Des équipes du CHU de Montpellier et de l’Inserm publient dans la revue Scientific Reports une étude portant sur une différence de poids de plus de 250 grammes entre les enfants nés à la suite d’une congélation embryonnaire et ceux issus d’embryons « frais ».

Atopic dermatitis: how allergens get on our nerves

Atopic dermatitis, or eczema, primarily affects infants and children, and manifests itself in hypersensitivity to allergens in the environment. A skin disease characterized by flare-ups, it is often treated with topical anti-inflammatories. A new study shows that immune cells and sensory neurons interact in the skin to form units that can detect allergens and trigger inflammation. A discovery that provides an insight into how atopic dermatitis works, and points the way to new therapeutic possibilities.

Dysentery: Shigella, bacteria with adaptation to respiration

Imagerie montrant la déplétion de l'oxygène au sein de la muqueuse intestinale par Shigella (vert), induisant une hypoxie (rouge) au sein des foyers infectieux inflammatoires (neutrophiles: marqués à l'aide du Myelotracker, bleu).

Bacillary dysentery caused by the intestinal bacteria Shigella is a major health problem in tropical regions and developing countries. Complications from this infection lead to several hundred thousand deaths a year, primarily among infants. Researchers from Inserm and the Institut Pasteur have studied the mechanisms of Shigella virulence. They found that these bacteria are not only able to consume the oxygen in colonic tissue in order to grow and create foci of infection, but can also adapt their mode of respiration so that they can continue to grow once the oxygen in these foci has been used up.

Identified: A Protein Essential for Chikungunya Virus Replication

Chikungunya is characterized by high fever and intense joint and muscle pain that can last for several months. The mechanisms of infection of human cells with the virus remain very poorly understood. Led by Ali Amara in collaboration with Marc Lecuit researchers from Inserm, Institut Pasteur, CNRS and Université de Paris have identified a protein that is crucial in order for the virus to replicate within its target cells.

Disarming a probiotic to improve its benefits

In a recent study, researchers managed to decipher certain pathways by which Escherichia coli Nissle 1917 produces both beneficial and toxic compounds. They then successfully created a modified strain with the same probiotic properties but an unactivated version of the toxin.

A Single Dose of Yellow Fever Vaccine Does Not Offer Lasting Protection to all Children

The World Health Organization (WHO) recommends a single dose of the yellow fever vaccine for individuals aged 9 months or older living in or traveling to areas at risk of disease transmission, but there is a lack of data on its long-term efficacy when administered to infants. José Enrique Mejía, Inserm researcher at Unit 1043 Center for Pathophysiology of Toulouse Purpan and Cristina Domingo from the Robert Koch Institute in Berlin have recently shown that around half of children initially protected by the vaccination at 9 months of age lose that protection within the next 2 to 5 years, due to disappearance of the neutralizing antibodies.

Elaboration et validation de l’iBox, le premier outil universel de prédiction du risque de perte de rein greffé basé sur l’intelligence artificielle.

Des équipes de deux centres majeurs de transplantation rénale de l’AP-HP (à l’hôpital Necker-Enfants malades et à l’hôpital Saint-Louis) et de l’Université de Paris, ont coordonné, au sein du « Centre d’expertise de la transplantation d’organe » de l’unité Inserm 970 dirigé par le Pr Alexandre Loupy, une étude internationale ayant permis d’élaborer et de valider iBox, le premier algorithme universel de prédiction du risque de perte de rein greffé.
