Neutralizing antibodies are produced after SARS-CoV-2 infection

A research group from Osaka University led by Professor Hisashi Arase and consisting of researchers from the Research Institute for Microbial Diseases, the Institute for Protein Research, the Immunology Frontier Research Center, the Center for Infectious Diseases, and the Graduate School of Medicine has discovered for the first time that both neutralizing antibodies that protect against infection as well as infection-enhancing antibodies that increase infectivity are produced after infection with SARS-CoV-2 by analyzing antibodies derived from COVID-19 patients.

Light-controlled on/off switch can help reset the biological clock

The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally.

Researchers suggest new strategies for finding drugs that neutralize key enzymes

Scientists from the UK's University of Bath explore racemases - an important type of enzyme that is linked to certain cancers and other life-threatening diseases while also being critical to cell function - in a paper published in the prestigious journal Chemical Society Reviews. The scientists also propose new strategies for finding drugs that neutralize these enzymes.

Latest articles provide novel insights into the mechanisms driving pridopidine neuroprotective effects

Prilenia Therapeutics B.V., a clinical stage biotech company focused on developing novel treatments for neurodegenerative and neurodevelopmental disorders, today announces the publication of three peer-reviewed journal articles, highlighting key aspects of the mechanism of action of its lead asset, pridopidine, and the importance of S1R activation as a mechanism to attenuate biological features of neurodegenerative diseases.

Genetic and molecular mechanisms make chemotherapy drug work for some cancer patients

The chemotherapy drug decitabine is commonly used to treat patients with blood cancers, but its response rate is somewhat low. Researchers have now identified why this is the case, opening the door to more personalized cancer therapies for those with these types of cancers, and perhaps further afield.

Study could help develop peptide siRNA carrier for human oral cancer

MUSC Hollings Cancer Center researchers are exploring the use of peptide carriers for the delivery of small RNA drugs as a novel treatment for cancer. The team's recent work, published online March 19 in the Molecular Therapy - Nucleic Acids journal, lays the foundation for developing a clinically relevant peptide carrier RNAi-based drug treatment strategy for human oral cancer.

“Paralyzed” immune cells can be reactivated by drugs in IDH-mutant gliomas

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

Telomere length decreases most rapidly from birth to age 3, shows study

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

First prognostic and therapeutic epigenetic biomarker for patients with pancreatic ductal adenocarcinoma

By 2030, pancreatic ductal adenocarcinoma (PDAC), the most lethal form of pancreatic cancer, is projected to become the second leading cause of cancer-related deaths in the United States.

Study reveals urine protein biomarkers of bladder cancer

Oncotarget published "Urine protein biomarkers of bladder cancer arising from 16-plex antibody-based screens" which reported that the current study examines urine samples from 66 subjects, comprising of 31 Urology clinic controls and 35 bladder cancer patients, using a Luminex based screening platform.

Studies highlight different aspects of link between obesity and cancer

Multi-factorial metabolic and inflammatory abnormalities in obesity, independently or in combination, seems to be the critical biological link of obesity, cancer and racial/gender health disparities. However, the specific cross-talk between these factors remain elusive.

Human self-organizing cardiac organoids mimic the architecture of a heart chamber

Self-organizing heart organoids created at the Austrian Academy of Sciences’ Institute of Molecular Biotechnology (IMBA) are also efficient injury and in vitro congenital disease models. These “cardioids” have the potential to transform studies into cardiovascular diseases and heart malformations.

Three-dimensional organization of genome is extremely dynamic during gamete formation

Inside the nuclei of cells, the genome is tightly organized (packaged). This three-dimensional (3D) genome organization is basic because it controls gene expression.

New technology improves efficacy of inflammatory bowel disease drugs

More Canadians suffer from inflammatory bowel disease (IBD) than anywhere else in the world, yet current treatments often have debilitating side effects and are not always effective.

High-fat, high-sugar diet reduces intestinal immune cell activity in mice

A team of researchers led by Thaddeus Stappenbeck discovered that a high-fat, high-sugar diet relates to reduced intestinal immune cell activity in mice.

Breast cancer survivors have higher risk of new cancer diagnosis compared to healthy individuals

A new study finds breast cancer survivors in general have higher risk of new cancer diagnosis compared to healthy individuals. The article, which appears in CANCER, states that compared to the general population in the United States, the risk of new cancer diagnoses among survivors was 20% higher for those with hormone receptor (HR) positive cancers and 44% higher for those with HR-negative cancers.
