Healing a mother’s skin lesions using her fetal cells?

Since the end of the 20th century, it has been proven that women who have been pregnant (including those who have miscarried or aborted) store the fetal cells of their children in their bone marrow for at least 50 years. The team of Professor Selim Aractingi – Paris Descartes Faculty of Medicine, Cochin Hospital (Paris hospital group) Dermatology Department, “Saint Antoine Research Center” Inserm joint research unit, and Université Pierre et Marie Curie – have recently proven that it is possible, in mice, to mobilize these fetal cells to accelerate the healing of chronic skin wounds. These results were published in Nature Communications on May 18, 2017.

From context to cortex: Discovering social neurons

The existence of new “social” neurons has just been demonstrated by scientists from the Institut de neurosciences des systèmes (Aix-Marseille University / INSERM), the Laboratoire de psychologie sociale et cognitive (Université Clermont Auvergne / CNRS), and the Institut de neurosciences de la Timone (Aix-Marseille University / CNRS). Their research on monkeys has shown that when these animals are made to perform a task, the presence or absence of a conspecific—that is, another monkey—determines which neurons are activated. Published in Social Cognitive and Affective Neuroscience, these findings broaden our knowledge of the social brain and help us better grasp the phenomenon of social facilitation.

Men/Women: not all equal in the face of allergic asthma

Researchers led by Jean-Charles Guéry of the Centre for Pathophysiology Toulouse Purpan (Inserm/Université Toulouse III – Paul Sabatier/ CNRS) are providing new insights into the possible link between male hormones and differences in gender in susceptibility to allergic asthma. This study demonstrates that hormones such as testosterone act on the immune system. The results are to be published in the scientific review The Journal of Experimental Medicine on 1 May 2017.

Vitamin D, a New Avenue in the Prevention of Alzheimer’s Disease?

Known to be a possible cause of certain chronic diseases, vitamin D deficiency is also believed to lead to a high risk of developing Alzheimer’s disease, especially where the diet is also poor in ‘good fats’ and antioxidant carotenoids. This is what two studies led by Catherine Féart and Cécilia Samieri, researchers at Inserm unit 1219 Bordeaux Population Health (BPH) (Inserm/ Bordeaux University), have shown. The research was published recently in Alzheimer’s & Dementia.

Tuesday May 23: European Obesity Day

Obesity is an excess of body fat that leads to health problems – principally type 2 diabetes and hypertension, and reduces life expectancy.

The World Health Organization (WHO) defines obesity as ”abnormal or excessive fat accumulation that presents a risk to health”.

According to WHO, 13% of adults worldwide were obese in 2014, a figure that had doubled since 1980.

Is the Link Between Early Cannabis Use and Academic Performance Becoming Clearer?

The hypothesis that cannabis consumption has a direct effect on concentration, motivation, and the academic success of young people in the long-term is supported by neuroscience research data which demonstrates specific lesions in teenage users. Maria Melchior, Inserm Research Director (Pierre Louis Institute of Epidemiology and Public Health, Inserm-Université Pierre et Marie Curie, Paris), and her French and North American colleagues wished to study the possible existence of a causal relationship between early cannabis consumption (before age 17) and the level of education completed later on. Their study, which involved more than 1,000 people, is being published today in the International Journal of Epidemiology.
