Simulating the Evolution of Signaling Signatures During CART-Cell and Tumor Cell Interactions

Area of Science:

• Oncology
• Immunology
• Computational Biology

Background:

• Immunotherapies, including chimeric antigen receptor T-cell (CART-cell) therapy, show promise in cancer treatment.
• Despite advancements, CART-cell therapy response rates vary significantly across patients and cancer types.
• There is a critical need for computational tools to predict CART-cell efficacy.

Purpose of the Study:

• To develop a computational framework for predicting CART-cell functionality and clinical efficacy.
