Abstrakt: The four critical issues are of significant relevance and need to be addressed: (1) The routes through which PM SB 2.5 sb access CNS; (2) the receptors microglia use to relay PM SB 2.5 sb neurotoxic signals; (3) PM SB 2.5 sb -induced microglial oxidative stress; and (4) the interactions between microglia and neurons. In addition, a study revealed that microglia cultures derived from mice missing functional NADPH oxidase, the enzyme responsible for microglial extracellular superoxide production, were insensitive to DEP-induced neurotoxicity, indicating that microglia-derived ROS are key for DEP-induced DA neurotoxicity [[100]].

Pre-treatment with fractalkine (50 pg/mL), a chemokine from neurons as a soluble anti-inflammatory signal for microglia [[102]], ameliorated DEP (50 g/mL)-induced H SB 2 sb O SB 2 sb production from microglia and protected against DEP-induced DA neurotoxicity in midbrain neuron-glia cultures [[84]]. In the presence of primary cortical microglia neuronal cell death increased by 2-3 fold after co-treatment with DEP, suggesting that microglia are important contributors to DEP-induced CGN neurotoxicity, possibly due to soluble intermediates since microglia-conditioned medium by DEP treatment was also toxic to CGNs [[101]].
