Bioengineered recombinant vault nanoparticles coupled with NY-ESO-1 glioma-associated antigens induce maturation of native dendritic cells
PURPOSE: Glioblastoma prognosis remains grim despite maximal, multimodal management. Recent literature has demonstrated an increase in research devoted to experimental treatments, particularly those relying on the foundations of active immunotherapy with promising results. We hypothesize that the utilization of bioengineered recombinant vault nanoparticles coupled with glioma-associated antigens, such as the NY-ESO-1 peptide, may be capable of stimulating native dendritic cell (DC) maturation and inducing an anti-tumor response.
METHODS: Immature DCs were cultured from the bone marrow of 4-6-week-old C57BL/6 mice. The three treatment groups consisted of: (1) DC and media, (2) DC with mCherry vault, and (3) DC with NYESO and vault. DC maturity was assessed via flow cytometric evaluation of CD11c, CD86, and MHC-II. Increase in CD86 Median Fluorescence Intensity (MFI) was analyzed in the CD11c+CD86+MHC-II+ population to determine the extent of maturation RESULTS: Our findings suggest that CP-MVP-NY-ESO-1-INT recombinant vault nanoparticles are efficiently bioengineered with exceptional integrity, are quickly internalized by immature DCs for antigen processing, and result in DC maturation.
CONCLUSION: This study reports our preliminary results, which demonstrate the feasibility and progress regarding our immunotherapeutic technique utilizing NY-ESO-1 packaged vault nanoparticles to prime DCs for subsequent anti-cancer therapies.
