Tiny mechanical forces can have a massive effect on T-cell activation
A new study reveals how tiny forces between T cells and their targets can help to jumpstart protective immune responses. Research published in Nature Communications on May 4 uses cutting edge microscopy techniques to track the association and dissociation between T cells and antigens. Read More
Hope for next-gen COVID-19 vaccines may rest in an unexpected region of the virus
Researchers further elucidated how antibodies produced in people who effectively fight off SARS-CoV-2 work to neutralize the part of the virus responsible for causing infection. The study, published in Science on May 4, describes how antibodies targeting sections of the virus outside of the receptor-binding domain may be useful in the development of vaccines and therapies.

How the South African SARS-CoV-2 variant evades antibodies
Computer modeling has demonstrated that one of the three mutations of the South African SARS-CoV-2 variant reduces its ability to bind to human cells. The results, published recently in the Journal of Medicinal Chemistry, also suggest that the mutation may help it escape some therapeutic antibodies. Read More
Naturally occurring molecule helps SARS-CoV-2 evade neutralizing antibodies
Researchers have identified naturally occurring molecules that are created from the breakdown of hemoglobin and block the binding of a subset of human antibodies to SARS-CoV-2. The discovery, published in Science Advances on April 22, may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus. Read More
Variant-resistant COVID-19 vaccines could be effective, cheap to make
Researchers have collaborated to create a new COVID-19 vaccine platform containing antigens against the fusion protein of the SARS-CoV-2 virus that could be effective against variants of the virus. The research was published online on April 15 in the Proceedings of the National Academy of Sciences. Read More
Will preprints have a lasting effect on publishing beyond COVID-19?
During the COVID-19 pandemic, 25% of all COVID-19-related scientific manuscripts were shared on preprint servers, a steep increase from previous usage and relative to traditional peer-review journals. An international team of researchers explored the critical role of preprint servers in disseminating epidemic-related information in an article published in PLOS Biology on April 2. Read More
2nd-gen stem cell-derived CAR gene therapy is more durable, effective against HIV
A novel second-generation chimeric antigen receptor (CAR)-based approach targeting HIV infection using the genetic modification of hematopoietic stem cells shows promise in preclinical models. The details of the study were published in PLOS Pathogens on April 1. Read More
Cancer anti-inflammatory drug has potential to treat severe COVID-19
A new study provides evidence that an inexpensive clinical-grade inhibitor that's already approved to treat cancer, called topotecan, can be used to treat severe COVID-19, even in the late stages of the disease. The findings were published in Cell on March 30. Read More
Hydrogen maps of SARS-CoV-2 main protease point to effective repurposed drugs
Scientists have used atomic maps of hydrogen atoms to determine that the SARS-CoV-2 main protease acts in unexpected ways when it comes into contact with a drug inhibitor. The research, published in the Journal of Medicinal Chemistry on March 23, provides key insights for efforts to repurpose existing drugs to develop candidates for treating COVID-19. Read More
Stable spike protein makes main SARS-CoV-2 variant more infectious
A new study finds that the enhanced infectivity of the dominant G614 variant of the SARS-CoV-2 virus largely results from the increased stability of its spike protein. Findings from the study were published in Science on March 16. Read More
