New Study Sheds Light on Blood-Brain Barrier Dysfunction in Aging

The central nervous system requires a tightly controlled environment for the neurons in the brain to function properly and be able to process information. The blood-brain barrier, which is maintained by specific brain endothelial cells lining blood vessel inner walls, controls the exchange of chemicals between the neurological and circulatory systems.

Research Sheds Light on Blood Cell Production in Mouse Skeleton

Imagine being able to count the different types of blood cells being formed inside the tiny bones of a mouse and pinpointing the strings and clusters of cells within the bone marrow that are responsible for producing specific types of blood cells.

Groundbreaking Physics Study Offers Insights Into Self-Organization of Biological Particles

Erin McCarthy '23, physics summa cum laude, is a rarity among young scientists. As an undergraduate researcher in Syracuse University's College of Arts & Sciences' Department of Physics, she guided a study that appeared in March 2024 in Physical Review Letters. It is the most-cited physics letters journal and the eighth-most cited journal in science overall.

Unraveling the Role of Gene Length in Aging

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.

New Approach to Constructing Human Artificial Chromosomes Avoids Unintended Multimerization

Constructing human artificial chromosomes (HACs) in budding yeast overcomes the long-standing problem of uncontrolled multimerization – the rampant joining of similar molecules – and results in HACs that are large, stable, and structurally well-defined, researchers report.

Non-Immune Cells Form Memory, Boosts Inflammatory Response

An essential component of adaptive immunity is immunological memory, which is the capacity to react to a foreign material or antigen more quickly and intensely when exposed again.

Machine Learning Accelerates Personalized T Cell Therapy Development for Cancer Patients

Making a personalized T cell therapy for cancer patients currently takes at least six months; scientists at the German Cancer Research Center and the University Medical Center Mannheim have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.

Adhesion GPCR Mayo Plays Key Role in Midgut Development of Fruit Flies

Adhesion GPCRs belong to the large family of G protein-coupled receptors (GPCRs). There are about 700 variants in humans, which are responsible for sensory impressions, hormonal cycles, controlling the cardiovascular system and more.

Metabolic Insights into Immune Cell Activation and Response

Researchers from Children's Hospital of Philadelphia identified a key metabolite in cells that helps direct immune responses and explains at a single cell level why immune cells that most efficiently recognize pathogens, vaccines, or diseased cells grow and divide faster than other cells.
