Study profiles the nose to predict immune response during COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), resides in mucous membranes, making it easy to detect viral load in the nasal cavities. An international group of researchers has characterized the immunological and diagnosis characteristics of patients who may have or are confirmed […]

SARS-CoV-2 antibody test helps select donor blood samples for therapeutic use

Researchers have developed and applied a robust, versatile antibody test to assist health authorities in managing the coronavirus disease 2019 (COVID-19) pandemic, according to a study published January 14 in the open-access journal PLOS Pathogens by Andrea Gamarnik of the Fundación Instituto Leloir-CONICET in Argentina, and colleagues. As of November […]

Coronaviruses do not readily induce cross-protective antibody responses

Patients infected with either severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 produce antibodies that bind to the other coronavirus, but the cross-reactive antibodies are not cross protective, at least in cell-culture experiments, researchers report May 17 in the journal Cell Reports. It remains unclear whether such antibodies offer cross […]
