Tumor Microenvironment-Responsive Polypeptide Nanogels for Controlled Antitumor Drug Delivery

Area of Science:

• Biomaterials Science
• Nanotechnology
• Oncology

Background:

• Tumor microenvironment-responsive polypeptide nanogels are advanced biomaterials.
• They exhibit biocompatibility, biodegradability, and tunable properties.
• Their application in targeted antitumor drug delivery is crucial.

Purpose of the Study:

• To review the progress of polypeptide nanogels responding to the tumor microenvironment.
• To highlight their role in delivering antitumor drugs.
• To provide insights for developing novel antitumor nanoformulations.

Main Methods:

• Systematic review of research on tumor microenvironment-responsive polypeptide nanogels.
• Analysis of endogenous (reduction, ROS, pH, enzyme) and exogenous (light, temperature) stimuli-responsive mechanisms.
• Evaluation of drug release profiles and therapeutic outcomes.

Main Results:

• Polypeptide nanogels demonstrate selective drug delivery to tumor sites.
• Stimuli-responsive release enhances tumor cell uptake and therapeutic efficacy.
• These nanogels improve drug distribution and minimize systemic toxicity.

Conclusions:

• Tumor microenvironment-responsive polypeptide nanogels are promising for targeted cancer therapy.
• Their tunable nature allows for precise control over drug release.
• Further development holds potential for more effective antitumor nanoformulations.
