FGF2 was conjugated to superparamagnetic iron-oxide nanoparticles (SPIONs) using carbodiimide chemistry, and the resulting FGF2-SPIONs were confirmed by dynamic light scattering (DLS), zeta potential, dot-blot analysis and Prussian Blue iron-staining. In vitro, treatment with FGF2-SPIONs evidenced increased therapeutic effects (attenuated TGFβ-induced HSCs activation, migration and contraction) of FGF2 in TGFβ-activated HSCs and ameliorated early liver fibrogenesis in vivo in acute carbon tetrachloride (CCl4)-induced liver injury mouse model. In contrast, free FGF2 showed no significant effects in vivo. Altogether, this study presents a promising therapeutic approach using FGF2-SPIONs for the treatment of liver fibrosis.Treatments of neurodegenerative diseases (NDDs) are severely hampered by the presence of the blood-brain barrier (BBB) precluding efficient brain drug delivery. The development of drug nanocarriers aims at increasing the brain therapeutic index would represent a real progress in brain disease management. PEGylated polyester nanoparticles (NPs) are intensively tested in clinical trials for improved drug delivery. Our working hypothesis was that some surface parameters and size of NPs could favor their penetration across the BBB and their neuronal uptake. Polymeric material PEG-b-PLA diblocks were synthesized by ring opening polymerisation (ROP) with PEG2000 or PEG5000. A library of polymeric PEG-b-PLA diblocks NPs with different physicochemical properties was produced. The toxicity, endocytosis and transcytosis through the brain microvascular endothelial cells were monitored as well as the neuronal cells uptake. In vitro results lead to the identification of favourable surface parameters for the NPs endocytosis into vascular endothelial cells. NPs endocytosis took place mainly by macropinocytosis
