Protein lifetime and the stability of cell structures

(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...

Protein 'passport' helps nanoparticles get past immune system

The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices like ...

Researchers build most complex synthetic biology circuit yet

Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in such circuits has ...

What purpose do reduced mitochondria serve?

A few years ago, scientists discovered a curious case of protozoa (oxymonads) that do not have mitochondria. Since then, the research group of Associate Professor Hampl from the Faculty of Science of Charles University and ...

New understanding of the inner world of lysosomes

Researchers at Duke-NUS Medical School and colleagues in Singapore have identified a protein that transports degraded membrane lipids out of lysosomes, cellular organelles that are the breakdown factories of cells. The findings, ...
