Researchers at Scripps Research Institute have used the blood of recovered COVID-19 patients to identify potent antibodies that protect against SARS-CoV-2. The study, published in Science, has shown the antibodies’ successful use in animal models and human cell cultures.
Dexamethasone, a steroid drug typically used to treat inflammation in conditions such as arthritis and asthma, has recently been tested as part of the Recovery trial at Oxford University (UK), and results are looking positive.
A recent analysis of COVID-19 cases suggests that up to 45% of SARS-CoV-2 infections may be asymptomatic. This highlights the need for expansive testing and contact tracing to quash the pandemic.
Scientists have investigated the genetic variation in immunity against seven viruses including the SARS-COV-2. The results reveal some HLA variants that may provide the most effective immune response to the viruses.
Researchers at Rush University Medical Center (IL, USA) demonstrated that astrocytes, a type of brain cell can spread the HIV virus to peripheral organs, even when undergoing combination antiretroviral therapy (cART). Suggesting major improvement to current HIV treatments.
A COVID-19 vaccine is widely regarded as the panacea for a fast track to normal life. There are currently over 120 vaccine candidates in development, with ten already in clinical trials. Take a look at the front-runners.
Researchers have repurposed cancer immunotherapy tools to identify regions of SARS-CoV-2 to target with a vaccine. They believe the use of this strategy could help develop a vaccine that provides long-term protection from COVID-19.
Researchers from Princeton University have uncovered an antibiotic molecule capable of killing both Gram-negative and Gram-positive bacteria using two simultaneous mechanisms, while also avoiding antibiotic resistance.
The largest trial to date assessing the use of convalescent plasma therapy for COVID-19 has revealed that the treatment is effective in 76% of patients, with no adverse effects. Further research is needed to evaluate how to optimize this therapy.
