Excess Lipids in Muscle Cells as a Contribution to Muscle Aging

Repair Biotechnologies, the company I co-founded, develops therapies based on the ability to selectively clear only excess cholesterol inside cells. This is normally an undruggable target. Cholesterol is essential to cell function, but expensive to manufacture. Species evolved a central factory for cholesterol production, the liver, and a complicated system of distribution that delivers cholesterol to and from the liver as needed. The vast majority of cells in the body neither manufacture nor break down cholesterol, but are completely dependent on it. Worse, too much cholesterol is toxic, and cells have little ability to deal with that toxicity when it occurs due to age-related or obesity-related dysregulation of cholesterol transport.
