aptamer-functionalized lipid nanoparticles

Also known as: aptamer-functionalized lipid nanoparticles (LNPs), aptamer-functionalized LNPs

Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Here, we developed aptamer-functionalized lipid nanoparticles (LNPs) for targeted mRNA delivery to CD4+ T cells.

Usefulness & Problems

No literature-backed usefulness or problem-fit explainer has been materialized for this record yet.

Published Workflows

Objective: Develop aptamer-functionalized LNPs for targeted mRNA delivery to CD4+ T cells and evaluate their binding, in vitro transfection, in vivo biodistribution, and safety.

Why it works: The workflow combines CD4-binding aptamers with LNP mRNA carriers so that receptor-directed binding can improve delivery specificity to CD4+ T cells while preserving a tunable nanoparticle formulation for in vivo use.

Stages

  1. 1.
    Aptamer generation and LNP design(library_design)

    This stage provides targeting ligands for constructing CD4-directed LNPs.

    Selection: Use a validated CD4-binding aptamer and novel aptamers generated by a transformer-based AI language model for CD4-targeted LNP functionalization.

  2. 2.
    LNP formulation and physicochemical characterization(library_build)

    This stage creates the aptamer-LNP formulations to be tested and characterizes their physical properties before biological evaluation.

    Selection: Formulate LNPs with SM102 or MC3 and conjugate aptamers at controlled densities.

  3. 3.
    Binding assessment(functional_characterization)

    This stage tests whether aptamer-functionalized LNPs engage the intended CD4 target before downstream delivery studies.

    Selection: Assess selective binding to recombinant CD4.

  4. 4.
    In vitro transfection assessment(secondary_characterization)

    This stage tests whether target binding translates into selective cellular delivery in a cell-based assay before in vivo studies.

    Selection: Assess enhanced transfection of CD4+ versus CD4- T cells in vitro.

  5. 5.
    In vivo biodistribution and safety evaluation(confirmatory_validation)

    This stage confirms whether the targeted formulations retain delivery enrichment and suitable safety in vivo.

    Selection: Assess enrichment of mRNA delivery to immune-rich tissues and evaluate safety.
