T cells can completely prevent viral infections in humans

Scientists from Duke-NUS Medical School and the Singapore General Hospital have discovered that T cells-white blood cells that can destroy harmful pathogens-can completely prevent viral infection, to an extent previously thought only possible due to neutralizing antibodies.

Lower force leads to faster cell movement on aligned collagen fibers

In mechanobiology, cells' forces have been considered fundamental to their enhanced function, including fast migration.

Unraveling the molecular mechanisms of disease-causing mutations

Most mutations which cause disease by swapping one amino acid out for another do so by making the protein less stable, according to a massive study of human protein variants published today in the journal Nature. Unstable proteins are more likely to misfold and degrade, causing them to stop working or accumulate in harmful amounts inside cells.

Monoamine neurotransmitters emerge as architects of brain physiology

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.

Scientists uncover key factors for starting autophagy in cells

Recycling takes place in our cells at all times: in a process called autophagy, cell components that are no longer needed are enclosed by membranes and broken down into their basic building blocks.

New AI method predicts gene activity in human cells

Using a new artificial intelligence method, researchers at Columbia University Vagelos College of Physicians and Surgeons can accurately predict the activity of genes within any human cell, essentially revealing the cell's inner mechanisms.

Study reveals neutrophils' dynamic role in cancer progression

Neutrophils are the most abundant white blood cells in the human body, primarily recognized for their essential roles in fighting infections and regulating inflammation.

Study reveals how smell and hearing interact in mouse brains

Imagine you're at a dinner party, but you can't smell the food cooking or hear the dinner bell. Sounds like a dream, right? What if it wasn't?

Breakthrough in protein homeostasis offers potential for preventing Alzheimer’s

Scientists have uncovered a powerful ally in the fight against neurodegenerative diseases: a nucleolar complex that plays a pivotal role in maintaining cellular health through protein homeostasis (proteostasis), by which cells maintain the balance and proper functioning of their proteins.

Rice researchers develop new construction kit for engineering smart cells

Rice University bioengineers have developed a new construction kit for building custom sense-and-respond circuits in human cells.

Researchers grow tumor organoids from blood to tackle breast cancer metastasis

Tumor cells circulating in the blood are the "germ cells" of breast cancer metastases. They are very rare and could not be propagated in the culture dish until now, which made research into therapy resistance difficult.

Unveiling the role of gene inactivation in human disease

New work by Columbia researchers has turned a textbook principle of genetics on its head and revealed why some people who carry disease-causing genes experience no symptoms.

Predicting H5N1 disease severity based on T cell responses

New research led by scientists at La Jolla Institute for Immunology (LJI) suggests that many people already have immune cells on "stand by" to fight the H5N1 virus, also known as highly pathogenic avian influenza.

Researchers develop tool to measure biological age in individual cell types

A new priority research paper, featured as the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 22, was published on December 29, 2024. The paper is titled "Cell-type specific epigenetic clocks to quantify biological age at cell-type resolution."

Research reveals key to understanding kidney cancer treatment variability

Fighting cancer can seem like a deadly game of chance. While some patients may respond well to certain treatments, others might not be as fortunate.

Brain mapping reveals cell-specific aging patterns

Based on new brain mapping research funded by the National Institutes of Health (NIH), scientists have discovered that not all cell types in the brain age in the same way.

Unraveling retrotransposon mechanisms in centromere insertion

A joint research group team led by Sayuri Tsukahara and Tetsuji Kakutani of the University of Tokyo has clarified a mechanism of how retrotransposons, genetic elements that can "jump around" chromosomes and are known drivers of evolution, preferentially insert in the centromere.
