Mouse Tumor Models for Advanced Cancer Immunotherapy

Area of Science:

• Oncology
• Immunology
• Preclinical Research

Background:

• Cancer immunotherapy advancements necessitate complex animal models.
• Mice are widely used for tumor modeling due to cost, rapid reproduction, and genetic manipulability.
• A significant challenge is the high failure rate of mouse-derived results in human clinical trials.

Purpose of the Study:

• To review current immunocompetent and immunocompromised mouse models for human tumors.
• To discuss the evaluation of immunotherapeutic agents using these models.
• To highlight the importance of tumor microenvironment and heterogeneity in preclinical models.

Main Methods:

• Review of existing literature on mouse cancer models.
• Analysis of immunocompetent and immunocompromised models.
• Focus on models relevant to immunotherapy, including CAR T-cells and immune checkpoint inhibitors.

Main Results:

• Mice models offer advantages but suffer from translation issues to human trials.
• Tumor microenvironment and heterogeneity are critical factors for model reliability.
• Various immunocompetent and immunocompromised models are employed for preclinical immunotherapy testing.

Conclusions:

• Improving mouse models by incorporating tumor microenvironment complexity is essential.
• Accurate preclinical models are vital for predicting the efficacy of cancer immunotherapies.
• This review provides an overview of current mouse models for evaluating immunotherapeutic agents.
