DHA promotes small LB formation and normalizes LPS-induced microglial hypertrophy. A Examples of activated microglial morphologies and LB formation from control and treated organotypic hippocampal slice cultures. In the presence of DHA, more small (<0.5 μm) LBs are present compared to other conditions. In LPS-treated cultures, the activated microglia contain fewer LBs compared to others. Arrows indicate small LBs; triangles indicate larger LBs. Scale bar 10 μm. Green, Iba-I. Red, ADRP. B LB density under various treatments with various LB sizes in microglia. *p < 0.05.
