Pyroptosis-inducing active caspase-1 as a genetic adjuvant in anti-cancer DNA vaccination. | LitMetric

AI Article Synopsis

Article Abstract

Pyroptosis is a recently discovered form of inflammatory programmed necrosis characterized by caspase-1-mediated and gasdermin D-dependent cell death leading to the release of pro-inflammatory cytokines such as Interleukin-1 beta (IL-1β). Here, we evaluated whether pyroptosis could be exploited in DNA vaccination by incorporating a constitutively active variant of caspase-1 to the antigen-expressing DNA. In vitro, transfection with constitutively active caspase-1 DNA induced pro-IL-1β maturation and IL-1β release as well as gasdermin D-dependent cell death. To test active caspase-1 as a genetic adjuvant for the induction of antigen-specific T cell responses, mice were vaccinated intradermally with a DNA vaccine consisting of the active caspase-1 plasmid together with a plasmid encoding an ovalbumin-derived CD8 T cell epitope. Active caspase-1 accelerated and amplified antigen-specific CD8 T cell responses when administered simultaneously with the DNA vaccine at an equimolar dose. Moreover, upon challenge with melanoma cells expressing ovalbumin, mice vaccinated with the antigen vaccine adjuvanted with active caspase-1 showed significantly better survival compared to the non-adjuvanted group. In conclusion, we have developed a novel genetic adjuvant that for the first time employs the pyroptosis pathway to improve DNA vaccination against cancer.

Irreversible electroporation (IRE) is a minimally invasive ablation technique that compromises integrity of the cell membrane through the application of short duration, high voltage electric pulses to induce cell death. Adverse effects of IRE such as muscle contractions are reduced with higher frequency biphasic pulsing, commonly known as high-frequency irreversible electroporation (H-FIRE). IRE and H-FIRE treatments have shown to increase immune activation through the induction of both immediate and delayed cell death, indicated by the release of damage-associated molecular pathways, antigens, and proteins.
