Biomaterials can help modulate the immune activity of liver cells

Biomaterials are substances, natural or manmade, that are used in medicine to interact with the human body for various purposes, such as wound healing and tissue regeneration.

Alzheimer’s symptoms linked to COVID-induced brain injury

New research shows further evidence between COVID-19 infection and the development of long-term neurological symptoms. The findings found COVID-induced neuroinflammation and microvascular injury contributed to dementia-like symptoms. However, they also found evidence indicating a low possibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) directly invading the brain.

Genetic variation that regulates iron metabolism may enhance endurance performance in athletes

A genetic variation that regulates iron metabolism may enhance athletes' endurance performance, researchers at the University of Toronto have shown.

Researchers produce a detailed molecular atlas of lung development

Researchers at the Perelman School of Medicine at the University of Pennsylvania have produced a detailed molecular atlas of lung development, which is expected to be a fundamental reference in future studies of mammalian biology and of new treatments for diseases, such as COVID-19, that affect the lungs.

Researchers discover a gene mutation linked to schizophrenia

Researchers at The Feinstein Institutes for Medical Research, in collaboration with Columbia University, have identified a gene mutation that could result in schizophrenia, a chronic brain disorder that affects nearly one percent of the world’s population. T

Study may lead to more refined approaches for head and neck cancers

By targeting an enzyme that plays a key role in head and neck cancer cells, researchers from the UCLA School of Dentistry were able to significantly slow the growth and spread of tumors in mice and enhance the effectiveness of an immunotherapy to which these types of cancers often become resistant.

Researchers identify chemicals that keep HIV virus in dormant state

When the human immunodeficiency virus infects cells, it can either exploit the cells to start making more copies of itself or remain dormant--a phenomenon called latency.

New technique traces genetic and epigenetic origins of DNA to reveal hidden cancers

A new technique that can trace which tissues and organs the DNA in our blood comes from has been reported today in the open-access eLife journal.

Changes in OASI gene expression increases risk of Alzheimer's and severe COVID-19 infection

Previous research identified the interferon-responsive OAS1 gene as a risk gene for Alzheimer's disease. OAS1 is an enzyme that binds to double-stranded RNA and induces the conformation to create oligoadenylates. They also activate RNase L to break down RNA.

Cellular senescence of cancer-associated fibroblasts play a key role in peritoneal dissemination

Through an analysis of cellular components (cell fractions) from malignant ascites (fluid buildup in the abdomen caused by gastric cancer), a research collaboration based in Kumamoto University (Japan) has demonstrated that cellular senescence of cancer-associated fibroblasts (CAFs) play an important role in the peritoneal dissemination of gastric cancer foci (cells different from surrounding cells).

Genetic study identifies sex-dependent differences in major psychiatric disorders

An analysis of sex differences in the genetics of schizophrenia, bipolar disorder and major depressive disorders indicates that while there is substantial genetic overlap between males and females, there are noticeable sex-dependent differences in how genes related to the central nervous system, immune system, and blood vessels affect people with these disorders.

‘Zombie’ cells come to life after the death of the brain

In the hours after we die, certain cells in the human brain are still active. Some cells even increase their activity and grow to gargantuan proportions, according to new research from the University of Illinois Chicago.

Gene responsible for cholesterol dysregulation in brain cancer cells could be a target for future drugs

Most people relate cholesterol to heart health, but it is also a critical component in the growth and spread of brain cancer.

Study reveals a genetic variant linked to COVID-19 severity in young men

A study of young men with COVID-19 has revealed a genetic variant linked to disease severity.

Over-expression of LRRN4CL gene linked to metastasis of certain cancers to the lungs

A gene not previously linked to cancer has been shown to play a key role in the spread of certain cancers to the lungs, new research from scientists at the Wellcome Sanger Institute has shown.

Preemies have greater risk of death from chronic diseases in adulthood

The risk of dying from heart disease, chronic lung disease or diabetes in adulthood is twice as high for preemies —premature infants — as for the general population.

Stem cell therapy could help restore debilitating age-related muscle loss

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.
