In vivo generation of chimeric antigen receptor T (CAR-T) cells using messenger RNA (mRNA)-loaded lipid nanoparticles (LNPs) offers a transformative approach to cancer therapy. This method bypasses complex ex vivo manufacturing, enabling direct in-patient T cell reprogramming for enhanced accessibility and potential efficacy.

Area of Science:

  • * Immunology and Synthetic Biology
  • * Oncology and Precision Medicine
  • * Biotechnology and Nanomedicine

Background:

  • * Current chimeric antigen receptor T (CAR-T) cell therapy, while effective for hematologic malignancies, faces limitations in solid tumors due to cost, manufacturing complexity, and tumor microenvironment barriers.
  • * Ex vivo CAR-T cell processing requires extensive infrastructure, specialized logistics, and significant time, hindering broader clinical application and accessibility.

Purpose of the Study:

  • * To review advancements in in vivo CAR-T cell generation using messenger RNA (mRNA)-loaded lipid nanoparticles (LNPs).
  • * To explore strategies for T cell-targeted delivery and CAR design optimization for enhanced safety and efficacy.
  • * To discuss preclinical evidence, regulatory considerations, and barriers to clinical translation of this novel therapeutic modality.
