Combined administration of resolvin E1 and lipoxin A4 resolves inflammation in a murine model of Alzheimer's disease.

Dysfunction in the resolution of inflammation may play a key role in Alzheimer's disease (AD). In this study, we found that the levels of specialized pro-resolving lipid mediators (SPMs) in the hippocampus of 5xFAD mice are significantly lower than in non-transgenic littermates. We, therefore, tested the hypothesis that treatment with resolvin E1 (RvE1) and lipoxin A4 (LXA4) alone or in combination will reverse the neuroinflammatory process and decrease Aβ pathology.
