Scientists provide a new approach to model infectious diseases

In the midst of a devastating global pandemic of wildlife origin and with future spillovers imminent as humans continue to come into closer contact with wildlife, infectious-disease models that consider the full ecological and anthropological contexts of disease transmission are critical to the health of all life.

Researchers propose new way to treat chronic lung condition

Traditionally, an infection is thought to happen when microbes - bacteria, fungi, or viruses - enter and multiply in the body, and its severity is associated with how prevalent the microbes are in the body.

People with venom allergies are more likely to have bone marrow disorder

Researchers at Michigan Medicine found that people with venom allergies are much more likely to suffer mastocytosis, a bone marrow disorder that causes higher risk of fatal reactions.

Antibody response following SARS-CoV-2 mRNA vaccine is greater than natural infection

Researchers in the United States have provided the first evidence that messenger RNA (mRNA)-based vaccines against severe acute respiratory coronavirus 2 (SARS-CoV-2) induce a broader array of antibody subtypes against the viral spike protein than natural infection does.

Methotrexate impairs immunogenicity of BNT162b2 SARS-CoV-2 vaccine in patients with immune-mediated inflammatory diseases

Researchers from Germany and the USA recently investigated the cellular and humoral immune responses of patients with IMIDs on immunomodulatory treatment to mRNA COVID-19 vaccines. The research is published on the medRxiv* preprint server.

Despite sufficient information on COVID-19, Central PA residents worry about mixed messages

Residents of central Pennsylvania had the information they needed to slow the spread of COVID-19 early on in the pandemic, but were overwhelmed with worries about mixed messages and distrust of some sources, according to Penn State College of Medicine researchers.

Despite socioeconomic status, racial and ethnic populations endure worse COVID-19 outcomes

A research team, led by the University of Minnesota Medical School, found that regardless of socioeconomic status, Twin Cities residents of underrepresented racial and ethnic backgrounds endure worse COVID-19 outcomes compared to people who are white.

SARS-CoV-2 mRNA vaccine PTX-COVID19-B safe and highly immunogenic in preclinical study

COVID-19, the coronavirus disease of 2019, is one of the worst pandemics in human history. It emerged in December 2019 and is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nearly 164 million SARS-CoV-2 infections and 3.4 million deaths have been reported globally since the beginning of the pandemic, which is still raging in many countries.

Potent antibody with unique genetic signature and spike recognition mechanism neutralizes SARS-CoV-2

In a new study, researchers used an antibody discovery technology to identify a new potently neutralizing antibody with a unique mode of SARS-CoV-2 recognition. They reported their results on the bioRxiv preprint server.

Robust T cell and humoral immune response to SARS-CoV-2 in patients with immunodeficiency

A study of immune-deficient adults and children has shown that patients who fail to respond positively to infections and vaccinations have robust humoral immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) structural proteins.

SARS-CoV-2 B.1.1.420 and B.1.617.1 immune escape variants reported in France

Researchers discovered the first N440K variant and the new E484Q and L452R Indian variants isolated in France in a recent study. They presented the genetic mutations in the isolated genomes and the phylogenetic tree, including these strains among different SARS-CoV-2 clades. This work is posted on the bioRxiv preprint server.

Previous study has underestimated the true extent of racial disparities in COVID-19 deaths

More than a year into the pandemic, the disproportionate burden of COVID-19 among racial and ethnic minorities in the US has been well documented.

New coronavirus variants can be effectively eliminated by disinfection, thorough hand washing

The researchers found that the variants have a similar surface stability as the wild type virus under laboratory conditions, but can be effectively eliminated by disinfection and thorough hand washing, heat or alcohol treatment.

Researchers identify specific influenza targets that could lead to universal flu vaccine for indigenous populations

Researchers have identified specific influenza targets that could be used to better protect Indigenous people from experiencing severe influenza disease through a universal, T cell-based vaccine.

Scientists develop experimental direct-acting antiviral therapy to treat COVID-19

An international team of scientists from the Menzies Health Institute Queensland (MHIQ) at Griffith University and from City of Hope, a research and treatment center for cancer, diabetes and other life-threatening diseases in the U.S., have developed an experimental direct-acting antiviral therapy to treat COVID-19.

New COVID-19 testing technology is a cheaper, faster alternative to tube-based RT-PCR tests

Throughout the COVID-19 pandemic, supply chain shortages of reagents and test kits have limited the rapid expansion of clinical testing needed to contain the virus.

18 May 2021

New imaging technique helps reveal the best antibodies for COVID-19 detection

Vaccines are turning the tide of the pandemic, but the risk of infection is still present in some situations. If you want to visit a friend, get on a plane, or go see a movie, there is no highly accurate, instant test that can tell you right then and there whether or not you have a SARS-CoV-2 infection.

Study provides new basis to compare the effectiveness of different tuberculosis treatments

A new study published in Nature Communications provides an important new basis for comparing the effectiveness of different tuberculosis treatments.
