This study just blew my mind.
So tumor cells transfer their mitochondria into tumor infiltrating lymphocytes and basically stop them from doing their jobs in the process - metabolic dysregulation, senescence, immune memory loss, ...

Mitochondria with mutations in their DNA from cancer cells can be transferred to T cells in the tumour microenvironment, which leads to T cell dysfunction and impaired antitumour immunity.
