Inflammatory mediator release from primary rhesus microglia in response to Borrelia burgdorferi results from the activation of several receptors and pathways

摘要

BackgroundIn previous studies, neurons were documented to undergo apoptosis in the presence of microglia and live Borrelia burgdorferi, but not with either agent alone. Microscopy showed that several Toll-like receptors (TLRs) were upregulated in microglia upon B. burgdorferi exposure. It was hypothesized that the inflammatory milieu generated by microglia in the presence of B. burgdorferi results in neuronal apoptosis and that this inflammation was likely generated through TLR pathways.
