Discovery in parasite movement may offer insights into malaria

... "Since motility is so central to survival of this class of parasites, it's incredibly important that we understand the basic elements of their motile apparatus and how the different components are controlled by the parasite," Beckers said. "Toxoplasma is motile outside the host cell, not inside it. If we ...

Researchers discover protein that dissolves amyloid fibers

...that's where Hsp104 comes in. Hsp104 belongs to a class of proteins that sometimes are influenced by environmental factors. It is conceivable, Shorter explains, that a yeast cell in one type of environment can experience an abundance of Hsp104, which would then keep Sup35 from forming amyloid fibers in th...

'Nanobodies' herald a new era in cancer therapy

...l compared to conventional antibodies, this unique class of antibodies has been renamed 'nanobodies'. Having all the advantages of the conventional antibodies, nanobodies also have several more important characteristics: they are small and they keep their tumor-specific character. At the same time, they a...
