    From monkeys to humans: the importance of interspecies transmission in the emergence of retroviruses in Central Africa

    Most of the viral pathogenic agents that have emerged in humans in recent decades are of animal origin. Hence, researchers from the Institut Pasteur have recently proved, for the first time scientifically at the epidemiological level, that specific contact with a monkey is a risk factor for the transmission of a pathogenic retrovirus (STLV-1/HTLV-1) to humans

    Interactions between the nuclear pore and chromatin are critical for HIV-1 replication

    Little is understood about the molecular mechanisms that actually enable the HIV to integrate its genetic material into certain regions of the human genome. The scientists were able to find this link and determine the role played by the chromatin environment and nuclear pores in the replication of HIV-1.

    The "dream" of every cell is to become two cells

    Arnaud Echard (head of the Membrane Traffic and Cell Division Lab) and his team are working to understand how a parent cell physically "cleaves" itself in two to create two distinct daughter cells. The researchers revealed that intercellular bridges split and in doing so release a structure called "midbody remnant" (MBR) into the extracellular environment. This discovery could have a significant impact on cancer research, as the presence of MBR is thought to promote the uncontrolled production of tumor cells.

    Segmented filamentous bacteria, partners in intestinal immunity, finally cultured in vitro

    Despite the vital role of segmented filamentous bacteria in establishing gut immune homeostasis in vivo in mice, scientists, for the past 50 years, have been unable to reproduce this symbiosis in vitro to shed light on the cellular and molecular interactions involved. Now, scientists have successfully cultured and reproduced the complex life-cycle of these bacteria outside their host for the first time.

    Resident and recruited macrophages orchestrate the liver's defense against infection

    Scientists have demonstrated that liver-resident macrophages are rapidly killed by the pathogenic bacterium Listeria monocytogenes. This early death triggers the recruitment of macrophages from the bloodstream to the liver. These macrophages start by bringing the bacterial infection under control; then, in an unexpected development, they actually replace the liver-resident macrophages that have been killed by the infection.

    Defense mechanism against HIV-1 revealed

    Scientists have discovered how some of these restriction factors inhibit HIV replication in lymphocytes. These proteins belong to the IFITM (interferon-induced transmembrane proteins) family; they are broad-spectrum antiviral proteins that act on a wide range of viruses including influenza, dengue, etc. Little was previously known about their effect on HIV-1.

    A better understanding of the intestinal immunity

    The innate lymphoid cells contribute to immune defense by maintaining the integrity of the intestinal barrier. ILC are made in the bone marrow but must find their way to the gut mucosa where they perform their function. Scientists have discovered how this migration process is regulated.

    Blood Ebola survivors tested as short-term treatment option

    An international research consortium will assess whether treatment with antibodies in the blood of Ebola survivors could help infected patients to fight off the disease. If proven effective, this straightforward intervention could be scaled up in the short term and provide an urgently needed treatment option for patients in West Africa.

    A new mechanism of gene regulation in Listeria

    How do bacteria perceive their environment? How do they find and detect nutrients? How do they eat? In an article published in the journal Science, researchers reveal a new system of gene regulation in Listeria monocytogenes, the bacteria in food and responsible for listeriosis.
