Neurodegenerative diseases (i.e. Alzheimer's and Huntington's) often involves the formation of aggregates of proteins in a patients' brain, correlated with the process of degeneration. Some of these proteins are unique to the specific disease and others are commonly found in healthy individuals but also occur intertwined with the disease-linked types. Until now, these "common proteins" were thought to be an effect of sampling the tissues and were ignored as background. A new paper out today in PLoS Biology suggests, however, that these protein aggregates may be linked to aging. The main reason to think this is that they are found more widely (in a phyologenetic sense) than previously expected ... having been isolated in Caenorhabditis elegans, the laboratory classic roundworm model. And, in C. elegans, they seem to be linked to aging.Read the rest of this post... | Read the comments on this post...
