Alpha-mangostin attenuates brain inflammation induced by peripheral lipopolysaccharide administration in C57BL/6J mice

Abstract

Neuroinflammation is an important feature in the pathogenesis and progression of neurodegenerative diseases. Molecules with anti-inflammatory properties have been evaluated in animal models of neuroinflammation and neurodegeneration as an adjuvant therapeutic strategy. In the present study we have demonstrated that alpha-mangostin (α-MG), a natural xanthone purified from mangosteen pericarp, reduced brain levels of pro-inflammatory cytokine interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and 18 kDa translocator protein (TSPO) in an animal model of peripheral LPS-induced neuroinflammation. We think that evaluation of α-MG as an adjuvant treatment in preclinical models of AD, PD, multiple sclerosis and other diseases with known shared pathology merits further consideration.

Keywords: Cyclooxygenase-2; Interleukin-6; Lipopolysaccharide; Neuroinflammation; Peripheral infection; α-Mangostin.
