Gorilla treated with antibodies recovering from COVID, says US zoo

Winston, 48, was one of several gorillas among the San Diego Zoo Safari Park’s troop who were confirmed positive for the virus An elderly gorilla was recovering from a serious case of COVID-19 after he was treated with cutting-edge synthetic antibodies, the San Diego Zoo said Monday. Veterinarians are now identifying which animals to inject […]

No more needles for diagnostic tests? Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells — ScienceDaily

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19; or cytokines indicative of inflammation seen […]

Virus variant found in S. Africa may resist antibodies

Antibodies against the novel coronavirus may not work as well against a new variant of the virus identified in South Africa, early data suggest. Scientists recently raised concerns that the variant, known as 501.V2, may be resistant to COVID-19 vaccines, Live Science previously reported. Experts noted that the variant has accumulated a significant number of […]

Research reveals compromised transfer of SARS-CoV-2-specific antibodies through placenta

BOSTON – Recent analyses indicate that pregnant women and newborns may face elevated risks of developing more severe cases of COVID-19 following SARS-CoV-2 infection. New research led by investigators at Massachusetts General Hospital (MGH) and published in Cell reveals lower than expected transfer of protective SARS-CoV-2 antibodies via the placenta from mothers who are infected […]

COVID-19 severity affected by proportion of antibodies targeting crucial viral protein

COVID-19 antibodies preferentially target a different part of the virus in mild cases of COVID-19 than they do in severe cases, and wane significantly within several months of infection, according to a new study by researchers at Stanford Medicine. The findings identify new links between the course of the disease and a patient’s immune response. […]

NIH neuroscientists isolate promising mini antibodies against COVID-19 from a llama
