In vitro viability of bEnd.3 cells (A), primary astrocytes (B), and primary neurons (C) treated with Mel-lip, Mel-Tf-lip, kFGF-lip, kFGF-Tf-lip, PasR8-lip, and PasR8-Tf-lip at different phospholipid concentrations (100, 200, 400, and 600 nM) for 4 hours. Cell viability was determined by MTT assay. Data are expressed as means ± S.D. (n = 4). *P < 0.05.
