Suppression of COVID-19 waves reflects time-dependent social activity, not herd immunity

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and the University of Illinois Urbana-Champaign (UIUC) have developed a new mathematical model for predicting how COVID-19 spreads. This model not only accounts for individuals’ varying biological susceptibility to infection but also their levels of social activity, which naturally change over time. Using their […]

In rare cases, immune system fails despite HIV suppression

Antiretroviral therapy (ART) is usually very effective at suppressing HIV in the body, allowing a person’s immune system to recover by preventing the virus from destroying CD4+ T cells. Scientists have now identified a rare, paradoxical response to ART known as extreme immune decline, or EXID. Five individuals evaluated at the National Institute of Allergy […]

Biochemists described a new mechanism for autoimmunity suppression

RUDN biochemists suggested a new mechanism by which the human body prevents the development of autoimmune diseases, allergies and implant rejection. They report that regulatory T-cells are able to suppress the reproduction of autoimmune cells. The work was published in Molecular Immunology. The ability of the body to resist pathogenic factors is under the control […]
