Tumour cells in a mouse’s brain

A snapshot of a delicate web of tumour cells inside a mouse’s brain has clinched the top prize in this year’s Nikon Small World photography competition, which celebrates microscopy.

Tightly packed, upright strands of a protein known as actin border each cell, which contain green jumbles of tiny tubes, called microtubules, that surround a violet nucleus.

Bruno Cisterna Irrazabal at Augusta University in Georgia, who took the photo, is exploring whether the breakdown of the structures around nuclei could influence the development of neurodegenerative conditions, such as Alzheimer’s disease.

“One of the main problems with neurodegenerative diseases is that we don’t fully understand what causes them,” he said in a statement. “To develop effective treatments, we need to figure out the basics first.”
