Rosmarinic acid- and curcumin-loaded polyacrylamide-cardiolipin-poly (lactide-co-glycolide) nanoparticles with conjugated 83-14 monoclonal antibody to protect β-amyloid-insulted neurons

Polymeric nanoparticles (NPs) combined with lipids can have profound effects on treatment efficacy in patients with neurological disorders such as Alzheimer's disease (AD). We developed polyacrylamide (PAAM)-cardiolipin (CL)-poly(lactide-co-glycolide) (PLGA) NPs grafted with surface 83-14 monoclonal antibody (MAb) to carry rosmarinic acid (RA) and curcumin (CUR). This drug delivery system was used to cross the blood-brain barrier (BBB) and enhance the viability of SK-N-MC cells insulted with beta-amyloid (A beta) deposits. Experimental evidence revealed that an increase in the concentration of 83-14 MAb enhanced the permeability coefficient of RA and CUR using the nanocarriers. The levels of phosphorylated p38 and phosphorylated tau protein at serine 202 in degenerated SK-N-MC cells were in the order: A beta > (A beta + RA-CUR) > (A beta + 83-14 MAb-RA-CUR-PAAMPLGA NPs) > (A beta + 83-14 MAb-RA-CUR-PAAM-CL-PLGA NPs) approximate to control. The viability of SK-N-MC cells reduced with time and CL in 83-14 MAb-RA-CUR-PAAM-CL-PLGA NPs advantaged A beta-targeted delivery of RACUR. These results evidenced that the current 83-14 MAb-RA-CUR-PAAM-CL-PLGA NPs can be a promising pharmacotherapy to permeate the BBB and reduce the fibrillar AD-induced neurotoxicity.
