Our cover features a collage of immunofluorescence stainings of primary microglia with NF-κB p65 (green) and DAPI (blue). The image is taken from Shi et al. (pp. 665–676), where the authors studied the anti-inflammatory effect of natural chemical compound gx-50 from Chinese black pepper (Zanthoxylum bungeanum) in primary rat microglia and a mouse model of Alzheimer's disease (AD). Gx-50 reduced the release of pro-inflammatory mediators induced by amyloid ß and inhibited TLR4-mediated NF-κB/MAPK signaling cascade. This study suggests that gx-50 should be further analyzed as potential candidate drug for the treatment of AD.
