英文摘要
Most neurodegenerative diseases such as Parkinson's disease (PD) show neuronal inclusion body in the patient's brain. p62(A170) is one of the component proteins of the inclusion body, and it is believed that it plays an important role in the step of protein sequestration and induces unfolded proteins to the proteolysis by autophagy. In the present study, we clarified that p62(A170) was induced in the transcription level by proteasome inhibition or overexpression of alpha-synuclein. Furthermore, autophagy-related molecules, such as LC3, were colocalized with p62(A170) existing inclusion body.
