Parkinson's disease (PD) is a common neurodegenerative disease characterized by loss of dopaminergic neurons and intraneuronal accumulation of protein aggregates. The exact mechanisms leading to neuronal death in PD are not fully understood, but several different molecular pathways are involved, leading to the concept that molecular subtypes may coexist in the nosological spectrum of PD. To this respect, immune system activation, both in the periphery and inside the central nervous system, was detected as a common trait of several pathogenic pathways of PD. The current working hypothesis implies that immune cells shift towards a proinflammatory phenotype and trigger the production of neurotoxic cytokines, ultimately contributing to neurodegeneration. While it is very important to understand how commonly used antiparkinson drugs interact with such changes, the search for treatments which may directly or indirectly modulate immune function is a great opportunity for disease modification.

Abstract
Parkinson's disease (PD) is a common neurodegenerative disease characterized by loss of dopaminergic neurons and intraneuronal accumulation of protein aggregates. The exact mechanisms leading to neuronal death in PD are not fully understood, but several different molecular pathways are involved, leading to the concept that molecular subtypes may coexist in the nosological spectrum of PD. To this respect, immune system activation, both in the periphery and inside the central nervous system, was detected as a common trait of several pathogenic pathways of PD. The current working hypothesis implies that immune cells shift towards a proinflammatory phenotype and trigger the production of neurotoxic cytokines, ultimately contributing to neurodegeneration. While it is very important to understand how commonly used antiparkinson drugs interact with such changes, the search for treatments which may directly or indirectly modulate immune function is a great opportunity for disease modification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
