Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted substances through dynamic remodeling of the actin cytoskeleton, the cell's ...

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. "We know each of the proteins ...

Both images show individual red blood cells. The one on the right, produced by STED, more clearly shows the Piezo1 proteins (in green), which are a mechanical calcium channel and play a crucial role ...

Proteins are most well-known for their intricate structures. The α-helices and β-sheets that form from interactions between sidechains create distinct shapes that, along with the specific amino acid ...

Northwestern Medicine scientists have uncovered how a specific type of cell in the inner ear plays a commanding role in shaping the cellular landscape of the organ responsible for hearing, according ...

That means researchers can now use it to better understand how genes function, how diseases start and how to design better treatments. "Every single cell can have a different chromosome structure," ...

In a study published in Cell Reports, biomedical scientist Xuecai Ge at the University of California, Riverside and her team ...

Christophe Leterrier uses advanced microscopy to uncover neurons’ intricate nanostructure and dynamics while creating ...
