Covid-19, the CIML is mobilising for the AP-HM
Research institutes of the CNRS, Inserm and AMU, on the Luminy campus, including the CIML, Centre d'Immunologie de Marseille Luminy, INMED, LGBP, LP3, MIO, CPPM and the Faculty of Science are mobilizing to offer and bring to the AP-HM stocks of gloves and masks from their stocks.
A newly discovered memory in our bones: blood stem cells boost immunity by keeping a record of previous infections
A Franco-German research team led by Prof. Michael Sieweke, from the Center for Regenerative Therapies TU Dresden (CRTD) and the Center of Immunology of Marseille Luminy (CNRS, INSERM, Aix-Marseille University), today uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but they can also remember previous infectious encounters to drive a more rapid and more efficient immune response in the future.
When Stress Weakens the Immune Defenses
In previous years, various studies have established a link between psychological stress and reduced immune defenses, but the mechanisms involved remained poorly elucidated. Sophie Ugolini, Inserm Research Director at the Center of Immunology Marseille-Luminy, and her colleagues at CNRS and Aix-Marseille Université have recently shown that such a link is to a large extent mediated by a type of receptor that binds to stress hormones: the β2-adrenergic receptor. Their findings have been published in Journal of Experimental Medicine.
