Antibody therapies for the treatment of COVID

Abstract The outbreak of COVID-19 the disease caused by infection of the coronavirus SARS-CoV-2 that began in December 2019 in Wuhan China has caused more than 2 990 559 confirmed human infections and 207 446 deaths as of 27 April 2020 (Coronavirus COVID-19 Global Cases by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University)

Longitudinal evaluation and decline of antibody responses

Jul 09 2020Antibody (Ab) responses to SARS-CoV-2 can be detected in most infected individuals 10-15 days following the onset of COVID-19 symptoms However due to the recent emergence of this virus in the human population it is not yet known how long these Ab responses will be maintained or whether they will provide protection from re-infection Using sequential serum samples collected up to 94

Coronavirus: Scientists hail 'groundbreaking' discovery of

May 04 2020Testing their collection of antibodies on cultured human cells researchers discovered one which binds to a specific part which is present in both SARS and the virus causing COVID-19 The discovery could offer an initial step towards developing a fully-human antibody to treat or prevent the disease which has infected more then 3 5 million

A human monoclonal antibody blocking SARS

Mar 11 2020SARS-CoV-2 Neutralizing antibodies can alter the course of infection in the infected 108 host supporting virus clearance or protect an uninfected host that is exposed to the 109 virus 4 Hence this antibody offers the potential to prevent and/or treat COVID-19 and 110 possibly also other future emerging diseases in humans caused
