Published Workflows
Objective: Engineer a multifunctional LNP platform for PDAC that combines nucleic acid delivery, tumor targeting, and tumor microenvironment remodeling.
Why it works: The abstract presents the workflow logic as combining multiple mechanisms in one LNP formulation: folate-mediated tumor targeting, anti-CD47-mediated immune remodeling, and nucleic acid delivery, with an additional PDAC-specific promoter for pDNA cargo.

The platform depends on mRNA cargo and lipid nanoparticle formulation design. The abstract specifically highlights lipid chemistry, biodistribution control, and nano-engineering strategies as important design inputs.; requires optimization of lipid chemistry; requires control of organ-selective biodistribution; may require nano-engineering strategies to improve antigen presentation and T-cell priming
The abstract states that key barriers still persist, including precise tumor or lymphoid targeting, efficient intracellular mRNA release, and the immunosuppressive tumor microenvironment.; precise targeting of tumors or lymphoid tissues remains a barrier; efficient intracellular mRNA release remains a barrier; immunosuppressive tumor microenvironment remains a barrier
