A study of mouse models of Parkinson's disease (PD) and dementia with Lewy bodies finds that the coffee component eicosanoyl-5-hydroxytryptamide acts synergistically with caffeine, which was previously thought to be the neuroprotective component of coffee, to maintain the enzyme PP2A in an active state so that the enzyme can dephosphorylate pathogenic hyperphosphorylated α-synuclein proteins, implicated in PD; the two compounds may together prevent neurodegeneration and neuroinflammation and protect brain cells, according to the authors.
