Modulation of innate immune-related pathways in nicotine-treated SH-SY5Y cells.

ABSTRACT: Although nicotine has a broad impact on both the central and peripheral nervous systems, the molecular mechanisms remain largely unknown, especially at the signaling pathway level. To investigate that aspect, we employed both conventional molecular techniques, such as quantitative real-time PCR and Western blotting analysis, and high-throughput microarray approach to identify the genes and signaling pathways that are modulated by nicotine. We found 14 pathways significantly altered in SH-SY5Y neuroblastoma cells. Of these, the Toll-like receptor pathway (TLR; p = 2.57 × 10(-4)) is one of the most important innate immune pathways. The death receptor pathway (DR; p = 8.71 × 10(-4)), whose transducers coordinate TLR signals and help conduct the host immune response to infection, was also sign
