The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different versions of this protein in the parasite in high detail.
During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two.
A generally accepted 44-year-old assumption about how certain kinds of bacteria make energy and synthesize cell materials has been shown to be incorrect by a team of scientists led by Donald Bryant, the Ernest C. Pollard Professor of Biotechnology at Penn State University and a research professor in the Department of Chemistry and Biochemistry at Montana State University.
Malfunctioning machines can cause a slew of problems, but when those machines are cells and genes, the result is often cancer. Scientists have identified a new protein that is crucial to the cell's response to dietary amino acids.
In cancer, genes turn on and off at the wrong times, proteins aren't folded properly, and cellular growth and proliferation get out of control.
A new tool allows scientists to see the immune system like never before.
Understanding the steps to the intricate dance inside a cell is essential to one day choreographing the show.
University of Oregon-made technique is putting new light on machinery driving intracellular transport.
Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer.
Several neurologically based afflictions, such as Huntington's, Parkinson's, and Alzheimer diseases, have been correlated to a higher than normal presence of a specific type of enzymes, called transglutaminases (TGase) in the human body. TGases, whose function is to catalyze covalent bonds among proteins, are commonly found in several different human tissues.
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
