Scientists studying
neuronal malfunctioning, long thought to be a result of a cell’s
reaction to stress, may have unlocked a new understanding and even a
treatment plan for the future. Science Daily explains that neurodegenerative diseases such as
Alzheimer’s and Parkinson’s are caused in part by a cell’s
reaction – or lack thereof – to stress. Scientists from Harvard
and NYU have identified a protein modification that signals for the
cell to begin protein synthesis, in turn strengthening and protecting
the cell from attack.
Oxidative attack –
the focus of this research – is when cells are exposed to hazardous
conditions (pollution, cigarette smoke, radiation). Exposure to these
stimulates the stress response in cells to begin degradation of weak or
damaged proteins. It is speculated that with less impaired proteins
in the way, the cell can begin protein synthesis and restructure
itself. Using this new research, scientists may be able to harness
the removal
of such proteins and one day focus on a treatment plan for neurodegenerative
diseases.
