Watch immune cells dig tunnels in tissues

White blood cells called cytotoxic T lymphocytes (CTLs) dig tunnels in tissues, potentially allowing other CTLs to quickly reach infected cells and tumor cells, researchers report December 1st in Biophysical Journal. The ...

Clearing the course for glycans in development of flu drugs

There is no hole-in-one drug treatment when it comes to the flu, but that doesn't stop scientists from trying to sink one. Especially since as many as one in five Americans gets the flu. The reported estimated cost of this ...

Watch how cells squeeze through channels

Observations of cells moving through small channels shed new light on cell migration in 3-D environments, researchers report October 6 in Biophysical Journal. The findings also reveal how cancer cells may penetrate tissues ...

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

Pioneering method reveals dynamic structure in HIV

Viruses are scary. They invade our cells like invisible armies, and each type brings its own strategy of attack. While viruses devastate communities of humans and animals, scientists scramble to fight back. Many utilize electron ...

Cell removal as the result of a mechanical instability

Researchers at Kanazawa University report in the Biophysical Journal that the process of cell removal from an epithelial layer follows from an inherent mechanical instability. Moreover, the forces generated by an extruding ...

'Relaxed' T cells critical to immune response

Like finding that needle in the haystack every time, your T cells manage what seems like an improbable task: Quickly finding a few invaders among the many imposters in your body to trigger its immune response.
