Neuronal 'traffic jam' marks early Alzheimer's disease

...s, said Goldstein. "What we saw quite early in the life of those animals -- well before any plaque deposition -- were obvious axonal defects," said Goldstein. "We saw large swellings in their axons. And when we looked at those swellings using electron microscopy and biochemical markers, they looked just l...

Timing is everything: First step in protein building revealed

...eidea is to really know at the molecular level how life is puttogether," says Jon Lorsch, Ph.D., professor of biophysics andbiophysical chemistry, one of the departments in Johns Hopkins'Institute for Basic Biomedical Sciences. "We see disease largely as anincorrect timing event -- the wrong thing happeni...

Plants, animals share molecular growth mechanisms

... genes have survived through time as multicellular life evolved, they have been conserved in both plants and animals, Szymanski said. So, some of the plant proteins that comprise the ARP2/3 and the WAVE complexes are interchangeable with proteins in animals. Others proteins are not interchangeable, and Sz...

"It's very time consuming to do that, but without that information we don't know how these parasites are transmitted." And without basic systematics and taxonomic information about par...

Combination therapy boosts effectiveness of telomere-directed cancer cell death

...chromosomes that play a key rolein controlling the life span of cells. With every cell division,telomeres get a bit shorter until eventually they become so short thatthe enzymes that copy DNA for cell division no longer work properly andthe cell stops dividing. In a sense, telomeres function as a kind ofc...

Finding Cures For Tropical Diseases: Is Open Source An Answer?

There's aparadigm in life science and drug development : only "lucrative""markets" get exploited by R&D companies. In many occasions I'veseen very promising drugs candidates or related research get cannedbecause no money was to be made with it, even if millions would have...

NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

... fight the virus at different stages of the virus' life cycle. First, they inhibit viral RNA and protein synthesis. If this fails, interferons block the virus from forming particles which can be released and infect other neurons. This is critical, since the immune system does not kill infected precious ne...

Molecular machine may lead to new drugs to combat human diseases

...ng and pasting apparently has been conserved since life evolved. "It's thought that RNA, or a molecule related to RNA, possibly were the first biomolecules, because they are capable of both performing work and carrying around their own genetic code," Golden said. She and her research team used an intron...

A bacterial genome reveals new targets to combat infectious disease

...compromises the nematode's ability to complete its life cycle within its human host. Thus, understanding the details of this relationship may help identify new strategies for controlling diseases caused by filarial nematodes.
