    Body Composition and Cardiorespiratory Fitness of Overweight COVID-19 Survivors in Different Severity Degrees: A Cohort Study

    This prospective cohort aimed to assess body composition, cardiopulmonary fitness, and long-term symptoms of overweight individuals affected by COVID-19. Participants were divided into three groups according to the severity of acute COVID-19: mild, moderate, and severe/critical cases.

    CD8+ Lymphocytes Are Critical for Early Control of Tuberculosis in Macaques

    Researchers depleted innate and/or adaptive CD8+ lymphocytes in macaques and showed that loss of all CD8α+ cells significantly impaired early control of Mycobacterium tuberculosis infection, leading to increased granulomas, lung inflammation, and bacterial burden.

    Abstract

    IL-27 Produced during Acute Malaria Infection Regulates Plasmodium-Specific Memory CD4+ T Cells

    Researchers identified a critical window of CD4+ T cell responses that were targeted by IL-27. Neutralization of IL-27 during acute infection with Plasmodium chabaudi expanded specific CD4+ T cells, which were maintained at high levels thereafter.

    The Interaction of Human Immunodeficiency Virus-1 and Human Endogenous Retroviruses in Patients (Primary Cell Cultures) and Cell Line Models

    Scientists studied the differential expression of multiple human endogenous retroviruses (HERVs) families in the presence of HIV infection in the peripheral blood mononuclear cells of HIV-positive individuals, in HIV-infected cell lines, and in vitro HIV-infected macrophages/monocytes of healthy donors.

    Billions Boost Next-Generation COVID-19 Vaccine and Treatments

    Six months after announcing the $5 billion Project NextGen to develop treatments and vaccines that can “stay ahead of COVID-19,” the US government has awarded 20 contracts that reveal what much of that sum will support.

    Anti-COVID Drug Accelerates Viral Evolution

    Molnupiravir, an antiviral drug used to treat COVID-19, induces numerous mutations in the SARS-CoV-2 genome that can increase the rate at which the virus evolves — yielding viral variants that might survive and be passed on.
