• TCE disrupted power manufacturing inside mind cells — TCE interfered with mitochondria — your cell’s energy mills — inflicting a buildup of oxidative stress. Oxidative stress happens when your physique’s antioxidant defenses are overwhelmed, resulting in mobile harm.
This imbalance triggers irritation and ultimately kills dopamine neurons. The solvent “short-circuits” your mind’s power system, leaving neurons unable to carry out the demanding duties of sustaining motion and coordination.
• The solvent triggered a harmful protein buildup inside neurons — TCE publicity elevated the buildup of a sticky protein that clumps collectively within the brains of Parkinson’s sufferers. When these clumps type, they disrupt regular mind signaling, making a cascade of dysfunction that mirrors the human illness course of. The chemical air pollution brought on the identical poisonous mind modifications seen in Parkinson’s illness, even with none genetic danger components.
• TCE flipped a swap that sped up mind cell harm — The researchers discovered that TCE disrupted how mind cells clear up waste and management irritation. As soon as that system grew to become overactive, it created a sequence response of stress and harm contained in the cells, resulting in quicker lack of the neurons that management motion. In different phrases, TCE made the mind’s cleanup course of go haywire, turning it from protecting to damaging.
