Macrophage membrane-functionalized nanotherapeutics for tumor targeted therapy

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Cancer Therapy

Background:

• Conventional cancer therapies face limitations in specificity and efficacy.
• Macrophage membranes possess inherent tumor-targeting and immune-modulating capabilities.
• Biomimetic approaches using cell membranes are emerging for drug delivery.

Purpose of the Study:

• To review recent advances in macrophage membrane-encapsulated nanotherapeutics for cancer treatment.
• To discuss the preparation, characterization, and immunotherapy applications of these nanotherapeutics.
• To highlight future perspectives and challenges for clinical translation.

Main Methods:

• Preparation and characterization of macrophage membrane-encapsulated nanotherapeutics.
• Exploration of immunotherapy strategies including macrophage polarization and T-cell infiltration.
• Discussion of macrophage membrane modification and induction of immunological cell death.

Main Results:

• Macrophage membranes confer unique properties: tumor targeting, immune evasion, and payload release in the tumor microenvironment.
• These nanotherapeutics demonstrate potential in enhancing cancer immunotherapy.
• The review synthesizes current research on their preparation and application.

Conclusions:

• Macrophage membrane-encapsulated nanotherapeutics represent a promising strategy for targeted cancer therapy.
• Further research is needed to address limitations and facilitate clinical transformation.
• This biomimetic approach holds potential for developing advanced chemotherapies.
