Bacteria residing within tumor cells may boost cancer immunotherapy

Cancer immunotherapy may get a boost from an unexpected direction: bacteria residing within tumor cells. In a new study published in Nature, researchers at the Weizmann Institute of Science and their collaborators have discovered that the immune system "sees" these bacteria and shown they can be harnessed to provoke an immune reaction against the tumor.

Comprehensive mutation map helps better understand the biological processes underlying Alzheimer's

A study published in the journal eLife made all the possible mutations in the amyloid beta peptide and tested how they influence its aggregation into plaques, a pathological hallmark of Alzheimer's disease.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

An outlook on latest trends in peptide drug discovery and development

Currently, there are more than 80 peptide drugs on the global market and about twice as many in clinical development. Due to their beneficial properties, these biomolecules play already an important role in the treatment of diseases such as diabetes, cancer, hormone disorders, HIV infection, and multiple sclerosis.

Hidden genes in bacteriophages may be key to the development of new antibiotics

A study from the Center for Phage Technology, part of Texas A&M's College of Agriculture and Life Sciences and Texas A&M AgriLife Research, shows how the "hidden" genes in bacteriophages -- types of viruses that infect and destroy bacteria -- may be key to the development of a new class of antibiotics for human health.

Researchers propose new technique to detect SARS-CoV-2

SARS-CoV-2 infects human beings by attaching its surface-exposed spike proteins to ACE2 receptors, which in turn, are exposed on the cell membranes.

Immunity of COVID-19 patients may rely on antibodies from previous coronavirus infections

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.

Study: Sous vide cooking increases the digestibility of beef protein

Once used to prepare cuisine in only the finest restaurants, sous vide is now making its way into home chefs' kitchens. French for "under vacuum," the technique involves vacuum sealing food in a plastic pouch and then slowly cooking it in warm water.
