Abstract:
Cancer immunotherapies that train or stimulate the inherent immunological systems to recognize, attack, and eradicate tumor cells with minimal damage to healthy cells have demonstrated promising clinical responses in recent years. However, most of these immunotherapeutic strategies only benefit a small subset of patients and cause systemic autoimmune side effects in some patients. Immunogenic cell death (ICD)-inducing modalities not only directly kill cancer cells but also induce antitumor immune responses against a broad spectrum of solid tumors. Such strategies for generating vaccine-like functions could be used to stimulate a "cold" tumor microenvironment to become an immunogenic, "hot" tumor microenvironment, working in synergy with immunotherapies to increase patient response rates and lead to successful treatment outcomes. This Minireview will focus on nanoparticle-based treatment modalities that can induce and enhance ICD to potentiate cancer immunotherapy.
Insights
Nanoparticle-based treatments that induce immunogenic cell death (ICD) can enhance cancer immunotherapy. These approaches aim to convert non-responsive tumors into ones that can be targeted by the immune system, improving patient outcomes.
Area of Science:
- Oncology
- Immunology
- Nanomedicine
Background:
- Cancer immunotherapies show promise but benefit limited patients and can cause side effects.
- Immunogenic cell death (ICD) modalities directly kill cancer cells and stimulate antitumor immunity.
- Current strategies often fail to convert "cold" tumors into immunogenic "hot" tumors.
Purpose of the Study:
- To review nanoparticle-based treatments that induce and enhance ICD.
- To explore how these modalities can potentiate cancer immunotherapy.
- To discuss strategies for overcoming limitations in current immunotherapies.
Main Methods:
- Review of literature on nanoparticle-based ICD inducers.
- Analysis of mechanisms by which ICD enhances antitumor immune responses.
- Discussion of synergistic effects with existing immunotherapies.
Main Results:
- Nanoparticle-based treatments can effectively induce ICD in various cancer types.
- ICD induction by nanoparticles converts "cold" tumors to "hot" tumors, enhancing immune cell infiltration.
- Combining nanoparticle-induced ICD with immunotherapy increases treatment efficacy and broadens patient response.
Conclusions:
- Nanoparticle-mediated ICD is a promising strategy to enhance cancer immunotherapy.
- These approaches offer a way to overcome resistance to current immunotherapies.
- Further research into nanoparticle-based ICD holds potential for improved cancer treatment outcomes.

01:30Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
02:58Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
