Research reveals how a bacterial pathogen creates syringe-like structures to infect the intestines

Researchers at UT Southwestern Medical Center have discovered how a bacterium that infects people after they eat raw or undercooked shellfish creates syringe-like structures to inject its toxins into intestinal cells.

Using engineered stem cells to treat ALS and retinitis pigmentosa

Cedars-Sinai investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.

Study advances understanding of how melanocyte stem cells work to color hair

Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.

Research shows how exercise helps improve brain health

Physical activity is frequently cited as a means of improving physical and mental health. Researchers at the Beckman Institute for Advanced Science and Technology have shown that it may also improve brain health more directly.

Researchers discover the molecule responsible for guiding T cells toward tumors

Immunotherapy, particularly CAR T-Cell treatment for cancer, is extending the lives of many patients. But sometimes the therapy randomly migrates to places it shouldn't go, tucking into the lungs or other noncancerous tissue and causing toxic side effects.

Latest single cell technology identifies cell types related to CAD pathogenesis

A new study from the University of Eastern Finland identified 12 different cell types involved in the pathogenesis of coronary artery disease, CAD. The researchers also showed that the genetic risk factors for CAD take their effect especially via smooth vascular muscle cells, which change their phenotype as the disease progresses.

New study aims to elucidate the role of p21 in chronic lung inflammation

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 7, entitled, "p21 facilitates chronic lung inflammation via epithelial and endothelial cells."

Light-activated SpyLigation can turn on proteins both inside and outside of living cells

Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail.

New AI-based method for virtual staining of histopathological tissue samples

Researchers from the University of Eastern Finland, the University of Turku, and Tampere University have developed an artificial intelligence-based method for virtual staining of histopathological tissue samples as a part of the Nordic ABCAP consortium. Chemical staining has been the cornerstone of studying histopathology for more than a century and is widely applied in, for example, cancer diagnostics.

IOB researchers identify an active multi-layer embryonic brain circuit

Using a new approach for studying live embryonic mouse brains at single-cell resolution, researchers have identified an active multi-layer circuit that forms in the cortex during an unexpectedly early stage of development. Perturbing the circuit genetically led to changes similar to those seen in the brains of people with autism. The findings are reported today in Cell by a team based at the Institute of Molecular and Clinical Ophthalmology Basel.
