제목 Co-delivery of antigen and immune response modulator using nano micelle-generating dissolving microneedles for enhanced cancer vaccination
초록 Efficient delivery of tumor antigens and immunostimulatory adjuvants into lymph nodes is crucial for the maturation and activation of antigen-presenting cells (APCs), which subsequently induce adaptive antitumor immunity. Dissolving microneedle (DMN) has been considered as an promising device for transcutaneous immunization due to its superior ability to deliver vaccines through the skin layer. Here, we develop pluronic-based dissolving MNs in situ that generate nanomicelles (NMCs) upon their dissolution after cutaneous application, which facilitate the efficient encapsulation of poorly water-soluble toll-like receptor 7/8 agonist (R848) and the delivery of hydrophilic antigens. Application of MNs containing tumor model antigen (OVA) and R848 to the skin of EG7-OVA tumor-bearing mice induced a significant level of antigen-specific humoral and cellular immunity, resulting in remarkable anti-tumor activity.
