  • Fever drives enhanced activity, mitochondrial damage in immune cells
    Fever temperatures rev up immune cell metabolism, proliferation and activity, but they also — in a particular subset of T cells — cause mitochondrial stress, DNA damage and cell death, researchers have discovered. The findings offer a mechanistic understanding for how cells respond to heat and could explain how chronic inflammation contributes to the development […]
  • A two-dose schedule could make HIV vaccines more effective
    Researchers have shown that they can generate a strong immune response against HIV with two doses of a vaccine given one week apart.
  • Researchers identify sex-based differences in immune responses against tumors
    Researchers investigated differences in T-cell responses between male and female patients with lung cancer that may help direct future treatments. T-cell responses are part of the adaptive immune system, which is part of the body's 'smart system' that monitors for threats and fights them with customized defenses.
  • Unlocking the potential of patient-derived organoids for personalized sarcoma treatment
    Investigators developed the largest collection of sarcoma patient-derived organoids to date that can help improve the understanding of the disease and better identify therapies that are most likely to work for each individual patient. By using 3D mini tumor models that closely resemble a patient's tumor, treatments could be tailored more effectively, paving the way […]
  • Wastewater monitoring can detect foodborne illness
    First used in the 1940s to monitor for polio, wastewater surveillance proved such a powerful disease monitoring tool that the U.S. Centers for Disease Control and Prevention (CDC) established the National Wastewater Surveillance System to support SARS-CoV-2 monitoring in September of 2020. Now, a team of scientists have shown that domestic sewage monitoring is useful […]
  • Stroke rates increasing in individuals living with SCD despite treatment guidelines
    The incidence of stroke continues to increase for adults and children living with sickle cell disease (SCD) despite the Stroke Prevention Trial in Sickle Cell Anemia (STOP) establishing standards of care like transfusions and tests to measure blood flow in the brain for those deemed high-risk, according to a new study.
