Reprogramming T-cell metabolism to enhance adoptive cell therapies

Area of Science:

• Immunology
• Cellular Metabolism
• Cancer Therapy

Background:

• Adoptive cell therapy (ACT) is effective for hematological malignancies.
• Solid tumors present challenges due to an immunosuppressive and metabolically demanding tumor microenvironment (TME).
• T-cell metabolism is intrinsically linked to T-cell function and persistence.

Purpose of the Study:

• To review T-cell metabolism across different life stages.
• To explore T-cell metabolic and mitochondrial insufficiency within the TME.
• To discuss strategies for enhancing ACT efficacy by targeting T-cell metabolism.

Main Methods:

• Review of current literature on T-cell metabolism.
• Analysis of T-cell metabolic and mitochondrial function in the context of the TME.
• Discussion of potential metabolic pathway manipulations.

Main Results:

• Established models of T-cell metabolism provide a framework for understanding T-cell function.
• The TME imposes significant metabolic and immunosuppressive challenges on infused T cells.
• Metabolic and mitochondrial pathways can be modulated to improve T-cell persistence and function.

Conclusions:

• Understanding T-cell metabolism is crucial for overcoming TME-related therapy resistance.
• Targeting metabolic pathways offers a promising strategy to enhance ACT efficacy in solid tumors.
• Further research into T-cell metabolism can improve patient outcomes in ACT.
