Oxygen levels at the time of activation determine T cell persistence and immunotherapeutic efficacy

P. P. Cunha, E. Minogue, L. C. Krause, R. M. Hess, D. Bargiela, B. J. Wadsworth, L. Barbieri, C. Brombach, I. P. Foskolou, I. Bogeski, P. Velica, R. Johnson

The paper shows that low oxygen levels during T cell activation enhance antitumour cytotoxicity, even when subsequent culture is under high oxygen.

Glutarate regulates T cell function and metabolism

E. A. Minogue, P. P. Cunha, A. Quaranta, J. Zurita, S. K. Sah-Teli, B. Wadsworth, R. Hughes, G. Grice, P. Velica, D. Bargiela, L. Barbieri, C. Wheelock, J. A. Nathan, P. Karppinen, I. P. Foskolou, R. S. Johnson

This study shows that glutarate regulates T cell function and metabolism by inhibiting KGDDs and modifying the pyruvate dehydrogenase E2 subunit, enhancing CD8+ T cell cytotoxicity and reducing tumor growth.

Lactate regulation of activation in CD8+ T cells

L. Barbieri, P. Velica, P. A. Gameiro, P. P. Cunha, I. P. Foskolou, D. Bargiela, H. Rundqvist, R. Johnson

This study shows lactate can displace glucose as a carbon source for activated CD8+ T cells and alters their transcriptome, affecting effector differentiation markers.

Modified HIF expression in CD8+ T cells increases anti-tumor efficacy

P. Velica, P. P. Cunha, N. Vojnovic, I. P. Foskolou, D. Bargiela, M. Gojkovic, H. Rundqvist, R. S. Johnson

This study shows that modifying HIF-2α expression in CD8+ T cells enhances their anti-tumor activity through improved cytotoxic function and resistance to hypoxia.

Lactate potentiates differentiation and expansion of cytotoxic T cells

H. Rundqvist, P. Velica, L. Barbieri, P. Gameiro, P. Cunha, M. Gojkovic, S. Mijwel, E. Ahlstedt, I. P. Foskolou, M. Ruiz-Perez, M. Arsenian-Henriksson, J. Ule, A. Ostman, R. Johnson

This study shows that lactate enhances the anti-tumour activity of cytotoxic T cells by increasing their proliferation and cytotoxicity during exercise.
