Abstract:
Activated microglia foster a neurotoxic, inflammatory environment in the mammalian central nervous system (CNS) that drives the pathology of neurodegenerative diseases including Parkinson's disease (PD). Moreover, mitochondrial fission promotes microglial inflammatory responses in vitro. Given that the NLRP3 inflammasome and mitochondria are central regulators of both inflammation and PD, we explore potential functions for the NLRP3 inflammasome and mitochondrial dynamics in PD. Specifically, we propose that inducible microglial mitochondrial fission can promote NLRP3-dependent neuroinflammation in hereditary and idiopathic PD. Further in-depth exploration of this topic can prompt valuable discoveries of the underlying molecular mechanisms of PD neuroinflammation, identify novel candidate anti-inflammatory therapeutics for PD, and ideally provide better outcomes for PD patients.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Porin Insertion in the Outer Mitochondrial Membrane
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...
