Role of Metabolism in Adoptive T Cell Therapy: Strategies and Challenges

Abstract

<p><strong><em>Significance:</em></strong> Immune cell therapy involves the administration of immune cells into patients, and it has emerged as one of the most common type of immunotherapy for cancer treatment. Knowledge on the biology and metabolism of the adoptively transferred immune cells and the metabolic requirements of different cell types in the tumor is fundamental for the development of immune cell therapy with higher efficacy.</p><p><strong><em>Recent Advances:</em></strong> Adoptive T cell therapy has been shown to be effective in limited types of cancer. Different types and generations of adoptive T cell therapies have evolved in the recent decade. This review covers the basic principles and development of these therapies in cancer treatment.</p><p><strong><em>Critical Issues:</em></strong> Our review provides an overview on the basic concepts on T cell metabolism and highlights the metabolic requirements of T and adoptively transferred T cells.</p><p><strong><em>Future Directions:</em></strong> Integrating the knowledge just cited will facilitate the development of strategies to maximize the expansion of adoptively transferred T cells <em>ex vivo</em> and <em>in vivo</em> and to promote their durability and antitumor effects.</p>
