Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Pharmacology

Background:

  • Targeted drug delivery aims to maximize therapeutic agent concentration at diseased cells while minimizing off-target effects.
  • Conventional liposomes have been used therapeutically for two decades but often show inefficiency in cellular drug delivery.
  • Novel unconventional or specialized liposomes are continuously developed to improve in vivo cell-specific delivery.

Purpose of the Study:

  • To review the types and characteristics of non-conventional liposomes in cancer therapy, focusing on chemotherapy and gene therapy.
  • To explore strategies for enhancing liposomal drug targeting to cancer cells.
  • To highlight the potential of combining specialized liposome attributes into dual-specialty vesicles.

Main Methods:

  • Analysis of liposome composition, size, and drug encapsulation methods (hydrophilic/hydrophobic).
  • Discussion of in vivo cell-specific delivery challenges and potential solutions.

    • Main Results:

    • Non-conventional liposomes offer diverse characteristics for drug encapsulation and delivery.
    • Combining attributes of multiple specialized liposomes into dual-specialty vesicles shows promise for enhanced targeting.
    • Limited studies exist on dual-specialty liposomes, indicating a need for more research.

    Conclusions:

    • Further investigation into dual-specialty liposomes is crucial for improving cancer therapy outcomes.
    • Optimizing novel liposomal formulations can significantly enhance targeting efficiency to cancer cells.
    • Targeted delivery via advanced liposomes represents a key strategy in modern cancer treatment.
