Molecular motors cooperate in moving cellular cargo

Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had imagined.

Research helps understand how the malaria parasite disguises itself to avoid detection by the immune system

Scientists are making strides in understanding how the malaria parasite Plasmodium falciparum disguises itself to avoid detection by the immune system. The findings could lead to the development of new drugs for a disease that causes more than 300 million acute illnesses and at least one million deaths each year, most of them in developing countries.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Fibril shape is the basis of prion strains and cross-species prion infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell.

Process called sumoylation regulates key ion channel

Researchers at the University of Chicago have found that a recently discovered biological process known as sumoylation -- until now thought to be active only in the nucleus -- also occurs near the cell's surface where it regulates at least one and possibly many kinds of proteins, providing a novel target for the development of new drugs.
