Alpha1-antichymotrypsin induces TNF-alpha production and NF-kappaB activation in the murine N9 microglial cell line.
Neuroscience letters(2009)
摘要
Microglia are known to accumulate in senile plaques of Alzheimer's disease (AD) together with a set of proteins including alpha(1)-antichymotrypsin (ACT). To investigate the biological effects of the interaction between ACT and microglia, we examined cytokine production by the murine N9 microglial cell line after ACT treatment. Real-time PCR analysis and specific immunoassays demonstrate that ACT triggers mRNA expression and release of TNF-alpha by N9 microglial cells. Furthermore, we show that ACT induces a significant increase in NF-kappaB nuclear translocation. Taken together, these data demonstrate that ACT might contribute to the inflammatory mechanisms present in AD senile plaques.
