SARS-CoV-2 manipulates host cell's RNA to weaken the immune response

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense system.

Targeted mRNA vaccines train the immune system to destroy cancer cells

No matter where cancer cells grow in the human body, they are a threat to our health and our lives. But instead of treating them with chemotherapy or radiation - which have undesirable side effects - what if we could train our own immune systems to kill the rogue cells?

Black cumin: A promising natural agent with potential against chronic diseases

Black cumin seeds contain diverse secondary metabolites, including thymoquinone, flavonoids, triterpenoids and alkaloids, that demonstrate broad antimicrobial, antioxidant, anti-inflammatory and anticancer activity. Early preclinical and limited clinical evidence shows therapeutic potential across chronic diseases, supported by mechanistic and structure activity relationship findings.

Comprehensive antibody map reveals how SARS-CoV-2 mutations evade immunity

Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have created the most comprehensive map to date showing how antibodies attach to the SARS-CoV-2 virus, which causes COVID-19, and how viral mutations weaken that attachment.

Researchers identify a previously unknown cellular mechanism crucial to coronavirus replication

The discovery could serve as a starting point for antiviral strategies. A research team at Ruhr University Bochum, Germany, has identified a previously unknown cellular mechanism crucial to the replication of coronaviruses: c-Jun N-terminal kinase (JNK) is activated during infection with human coronavirus HCoV-229E and mediates the phosphorylation of the viral nucleocapsid (N) protein, an integral step in the virus cycle.
