Holotomography in Cell Biology

Holotomography is a scientific method used to image cells in two- and three-dimensions without the need for sectioning or labeling with external proteins.

	Study reveals unknown mechanism that protects tumor cells from NK cell-mediated cytotoxicity Cancer cells have evolved multiple escape strategies to circumvent the body's immune defenses such as the attack by Natural Killer (NK) cells which normally swiftly kill abnormal cells by releasing cytotoxic products.

	Scientists uncover how proteins meet on the cell membrane Scripps Research scientists have uncovered the workings of a critical process in cell survival. Their study, published recently in the Proceedings of the National Academy of Sciences, is the first to show exactly how a protein called talin activates another critical protein, called integrin, to do its job on the cell membrane.

	Researchers discover new structure in human cells A new structure in human cells has been discovered by researchers at Karolinska Institutet in Sweden in collaboration with colleagues in the UK.

	How a single mutation can devastate cellular function A scientist has shown how a single mutation in a protein found in astrocytes reproduces fibrous globs that devastate cellular function.
