제목 Enhanced cancer chemo-immunotherapy using nanomicelle generating microneedles containing paclitaxel and TLR7/8 agonist
초록   A dissolving microneedle(MN) for transdermal drug delivery is an attractive method to improve therapeutic efficacy. Efficient delivery of low dose chemotherapeutic agent-paclitaxel and immunostimulatory adjuvants-resiquimod was synergized to demonstrate tumor killing effect and activation of antigen presenting cells. In this research, both therapeutic agents being water insoluble were dispersed with the help of amphiphilic triblock copolymer: Pluronic F127 based dissolving MNs in situ that generate nanomicells (NMCs) upon their dissolution after cutaneous application. Various Cancer cells were significantly killed via paclitaxel and combination of paclitaxel and resiquimod in vitro, while antigen presenting cells (dendritic cells) treated with same concentration of resiquimod along with the combination led to enhanced proliferation. In DCs, as to extraordinarily enhanced secretion of pro-inflammatory, the combination resulted in a considerable synergy effect for the immune responses.
