Amyloidosis plays a specific function inside the pathogenesis of neurodegenerative illnesses for instance Alzheimer’s disease (AD), Parkinson’s illness, and rheumatoid arthritis (RA). The occurrence of amyloidosis correlates together with the aging approach of the organism, and since today, old age is determined by the comfort of functioning plus the elimination of unpleasant disease.
