Advancing tumor immunotherapy through rationally engineered inorganic nanomaterials

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Immunology

Background:

• Tumor immunotherapy shows promise but faces challenges like immune escape and tolerance.
• Inorganic nanomaterials offer unique properties for overcoming these limitations.

Purpose of the Study:

• To review the interplay between inorganic nanomaterial properties and immunomodulatory functions in cancer immunotherapy.
• To elucidate molecular mechanisms of immune enhancement by nanomaterials.
• To highlight engineering strategies and clinical adaptation challenges.

Main Methods:

• Systematic review of literature on inorganic nanomaterials in tumor immunotherapy.
• Analysis of physicochemical properties and their impact on immune responses.
• Discussion of molecular mechanisms, engineering strategies, and clinical perspectives.

Main Results:

• Inorganic nanomaterials can be engineered to activate immune cells, induce immunogenic cell death (ICD), and overcome immune evasion.
• Their tunable properties allow for stimuli-responsive biodegradation and intrinsic immunostimulatory effects.
• Synergies are created with existing immunotherapy paradigms through various mechanisms.

Conclusions:

• Inorganic nanomaterials are powerful tools to potentiate tumor immunotherapy by addressing insufficient immune activation.
• Rational design of nanomaterial-based platforms is crucial for next-generation cancer immunotherapeutics.
• Further research into combinatorial strategies and clinical adaptation is needed.
