Sydney, May 12 (NationPress) A research team from Australia has discovered a tiny molecule that halts the process of cell death, marking a significant breakthrough that may pave the way for innovative therapies aimed at neurodegenerative disorders such as Parkinson’s and Alzheimer’s.
The group from the Walter and Eliza Hall Institute of Medical Research (WEHI), located in Melbourne, focused on identifying new compounds capable of inhibiting cell death, which could be instrumental in treating these debilitating conditions in the future.
These findings instill optimism for therapies that have the potential to slow or even cease the progression of neurodegenerative diseases.
After examining over 100,000 chemical substances, the researchers pinpointed a small molecule that targets a lethal protein known as BAX.
By disrupting the function of a well-characterized cell death protein, this molecule successfully prevents cells from dying.
“We were excited to discover a small molecule that specifically targets the killer protein BAX and inhibits its activity,” stated Professor Guillaume Lessene from WEHI.
“In most cases, but particularly in neurons, simply switching off BAX might be enough to reduce cell death,” Lessene added.
While medications that induce cell death are revolutionizing cancer treatments, the journey toward developing cell death inhibitors—potentially transformative for neurodegenerative diseases—has been fraught with challenges.
This novel molecule effectively targets BAX, which causes cell death by damaging mitochondria, the energy centers of cells.
“For the first time, we have managed to keep BAX away from mitochondria, allowing us to preserve cell life using this molecule,” said Kaiming Li, the lead author and researcher at the Dewson Lab.
“This could open doors for the next generation of cell death inhibitors to fight degenerative diseases,” Li mentioned in the research published in the journal Science Advances.
The study highlights the potential for discovering medications that obstruct cell death and may herald a new pathway for developing crucial disease-modifying drugs for Parkinson’s and Alzheimer’s, according to the research team.
