I did not know where to post my question, so here I am.
My mother has a severe case of oculopharyngeal muscular dystrophy and, at 44 years old, I am begining to feel the first symptoms (difficulties to swallow for instance).
I read somewhere that the muscular cells die because there is an accumulation of nocive proteins Inside the cell. Do you think autophagy could prevent this if done regularily and early enough in life?
thank you in advance for your answer!
