Reflecting on the past, it’s challenging for many to grasp the filth, stench, and lethality prevalent in cities until relatively recently. The disparity in life expectancy between urban and rural areas underscores the toll of living in such hazardous environments. Exploring the cellular level, lysosomes, acting as “recycling centers,” break down cellular wastes into basic components for the production of new cellular membranes, enzymes, and proteins.
The initiation of atherosclerosis is linked to a minor defect in the blood artery wall, with the accumulation of undigested garbage contributing to the problem. Despite cholesterol’s negative reputation, it is an essential component of cell membranes. Chemically altered cholesterol becomes more prone to sticking together, increasing immobility. Higher cholesterol levels in the blood expose it to harmful chemicals, turning it into a toxic substance.
This accumulation of molecular damage caused by age-related “lysosomal storage illnesses,” including neurological diseases, retinal degeneration, and atherosclerosis, is a focal point for anti-aging bioengineers. Addressing these issues involves wiping up the accumulated damage through interventions similar to enzymes created by cells in the rest of the population.
