Scientists catch heartbeat ‘molecular switch’ in action

Oxford University Radcliffe Department of Medicine researchers have developed a new method that uses a protein originally found in marine corals to visualise the flow of calcium that makes the heart beat. In a paper published in the journal Circulation Research, they used this technique to uncover the effects of genetic errors that contribute to […]

Faulty molecular master switch may contribute to AMD

A signaling pathway controlled by transforming growth factor beta (TGF-beta) could be involved in the progression of age-related macular degeneration (AMD). Researchers at the National Eye Institute (NEI), part of the National Institutes of Health, have found that interrupting TGF-beta signals to immune cells called microglia causes the cells to enter an activated, inflammatory state.
