Penn researchers reveal complex details of T-cell responses to mRNA COVID-19 vaccines

Messenger-RNA (mRNA) vaccines against the coronavirus that causes COVID-19 provoke a swift and strong response by the immune system's T cells - the heavy armor of the immune system - according to a study from researchers in the Perelman School of Medicine at the University of Pennsylvania.

Researchers assess the genetic features of T-cell immunity development to SARS-CoV-2 variants

The continuing emergence of new SARS-CoV-2 mutations allows the virus to spread more effectively and evade antibodies. However, it is unclear whether new strains are capable of evading T-cell immunity - one of the body's main lines of defense against COVID-19.

New system combines computer software and cryo-EM to determine 3D structures of RNA-only molecules

The single-stranded genetic material RNA is best known for guiding the assembly of proteins in our cells and carrying the genetic code for viruses like SARS-CoV-2 and HIV.

Long-running wars, not the weather, are to blame for resurgent hunger in Africa, study says

For years, it seemed the world was making progress eliminating hunger. Then, starting in 2014, the trend slid back slowly and reversed in many nations; now, some 700 million people - nearly 9 percent of the world's population - go to bed hungry, according to the UN.

Simple roundworm may hold the key to understanding cell death processes

A biologist at The University of Texas at Arlington hopes that a simple roundworm might hold the key to understanding novel cell death processes. Such knowledge could lead to improved therapies to treat a variety of conditions in humans, including cancer and neurological injuries.

Enzyme acts as a sensor to find the hiding spots of viruses

While some types of RNA viruses cloak themselves to hide inside a cell and create copies of themselves, a "detective enzyme" might be attuned to their whereabouts. A slight variation in their genomic code gives some people's cells the capacity to produce this sensor.

Researchers develop new method to quantify protein droplets involved in neurodegenerative diseases

Some proteins in cells can separate into small droplets like oil droplets in water, but faults in this process may underlie neurodegenerative diseases in the brains of older people. Now, Rutgers researchers have developed a new method to quantify protein droplets involved in these diseases.

Understanding how to regulate key enzyme may lead to new treatments for cancers, viral infections

A new study led by University of California, Irvine (UCI) researchers identifies two ways in which APOBEC3A - a vital enzyme that is responsible for genetic changes resulting in a variety of cancers while protecting our cells against viral infection - is controlled.

Structure of BRCA2 protein complex critical for DNA repair solved

The initials BRCA2 may be best known for a gene associated with many cases of breast cancer, and the protein encoded by the BRCA2 gene is critical to repairing breaks in DNA.

Study uncovers a subset of human short introns spliced out by a distinct mechanism

The interrupted non-coding regions in pre-mRNAs, termed “introns,” are excised by “splicing” to generate mature coding mRNAs that are translated into proteins.

Researchers identify genetic program in fruit fly that protects neurons from degeneration

Researchers at the University of Bonn have identified a previously unknown genetic program in the fruit fly. The genetic material involved controls the development of the neurons while also protecting them from degeneration.

Researchers develop silica nanostructure for selective synthesis of enantiomers in cells

As COVID-19 vaccinations are well underway, people await a return to normal life. However, fears also grow due to unforeseen side effects like rare thrombosis. In the body, life is maintained by the movement of substances or energy.

Researchers discover how PARP inhibitors selectively kill BRCA-mutant cancer cells

A team of Massachusetts General Hospital researchers has discovered how an important class of anti-cancer drugs called PARP inhibitors works, a finding that could help improve treatment and prolong survival for patients with breast cancer and other malignancies.

Study finds four circulating miRNAs which could effectively inhibit SARS-CoV-2 replication

In a new study, Chen-Yu Zhang's group from Nanjing University presents a rather striking finding that four circulating miRNAs, which are high in healthy people and much lower in older people and diabetic patients, could effectively inhibit SARS-CoV-2 replication by directly targeting the S protein.
