1 OBJECTIVE: This study aimed to investigate whether curcumin changed microglia to an anti-inflammatory M2-phenotype by activating the AMP-activated protein kinase (AMPK) signaling pathway. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
2 RESULTS: Curcumin enhanced AMPK activation in BV2 microglial cells in the presence and absence of LPS. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
3 The effects of curcumin were inhibited by an AMPK inhibitor or AMPK knockdown. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
4 The effects of curcumin were inhibited by an AMPK inhibitor or AMPK knockdown. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
5 Curcumin can activate AMPK in Hela cells, which do not express LKB1. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
6 However, both the CaMKKbeta inhibitor and siRNA blocked curcumin activation of AMPK in LPS-stimulated BV2 cells. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
7 Finally, curcumin enhanced AMPK activation in the brain area where microglia were over-activated upon LPS stimulation in an in vivo neuroinflammation model. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
8 CONCLUSION: Curcumin enhances microglia M2 polarization via the CaMKKbeta-dependent AMPK signaling pathway. Curcumin protein kinase AMP-activated non-catalytic subunit beta 1 Homo sapiens
