Immune systems of COVID-19 patients may rely on antibodies from earlier coronaviruses

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

Mapping antibody reactivity in COVID-19 patients by using multi-coronavirus protein microarray

In an exciting, state-of-the-art study currently available on the medRxiv* preprint server, US researchers created a multi-coronavirus protein microarray containing full-length proteins, peptide libraries, and overlapping protein fragments from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as four other human coronaviruses.

Lower CD4 T cell reactivity to seasonal coronaviruses found in healthcare workers with COVID-19

A new study by US-based researchers describes the results of a study on the immune response among healthcare workers, in particular, their T cell responses predating the pandemic.

Inflammation may contribute to the persistence of C. diff infection, shows study

A new study from North Carolina State University shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and providing nutrients that enable C. diff to thrive.

New antiviral repurposing study finds peptides that could prevent SARS-CoV-2-ACE2 binding

A new study reports the antiviral potential of peptides against SARS-CoV-2's spike protein.

Newly discovered biochemical pathway can protect cells from ferroptosis

The hallmarks of cancer include rapid cell-reproduction and metabolic activity. But these processes also lead to increased cellular stress and oxidation, and the risk of cell death.

Study suggests SARS-CoV-2 could affect aquatic wildlife

Researchers have found that oxidative stress and neurotoxicity biomarkers increased in tadpoles exposed to synthetic SARS-CoV-2 spike protein peptides.

Study shows how new antibiotic resistance genes arise from random DNA sequences

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal PLOS Genetics.

Study: TTR protein plays a protective role in Alzheimer's disease

A protein that wreaks havoc in the nerves and heart when it clumps together can prevent the formation of toxic protein clumps associated with Alzheimer's disease, a new study led by a UT Southwestern researcher shows.

New peptide can target specific pathogen without damaging the good bacteria

Drug-resistant bacteria could lead to more deaths than cancer by 2050, according to a report commissioned by the United Kingdom in 2014 and jointly supported by the U.K. government and the Wellcome Trust.

In-silico modeling provides new understanding of immune response to SARS-CoV-2

The COVID-19 pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has crippled global healthcare systems and triggered an economic crisis in many countries. The pandemic is not showing signs of a slowdown even in 2021 with a new and more infectious variant of the virus wreaking havoc in the UK and many other parts of the world.

Using a blood test to predict Alzheimer's disease risk during symptom-free stage

Using a blood test, a German-Dutch research team has predicted the risk of Alzheimer's disease in people who were clinically diagnosed as not having Alzheimer's disease but who perceived themselves as cognitively impaired (Subjective Cognitive Declined, SCD).
