Abstract
Tacrolimus (TAC) acts as an inhibitor of calcineurin, which inhibits the production of interleukin-2. In this study, we aimed to design a targeted delivery platform with poly (lactide-co-glycolide; PLGA) nanoparticles modified with chitosan (CS) and CD8AP17s aptamer (Apt). MOLT-4 cells as CD8 positive and JURKAT cells as CD negative were adopted to investigate the efficacy of the proposed delivery system in vitro. The particle size and Ζ potential of the TAC-PLGA-CS-Apt nanocomplex were 345 nm and 13.7 mV, respectively. Release study showed an efficient TAC release from complex in citrate buffer (pH 5.5). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that TAC-PLGA-CS-Apt nanocomplex was highly selective toward MOLT-4 cells. Complex increased the cellular uptake of TAC in MOLT-4 cells (target) while reducing its cytotoxicity in JURKAT cells (nontarget). Our study showed that complex nanoconjugate could efficiently deliver TAC into MOLT-4 cells as a model of cytotoxic T cell and it could be considered as a potential candidate for TAC delivery.
