Reviving exhausted T cells to tackle immunotherapy-resistant cancers

When the cells of our immune system are under constant stress due to cancer or other chronic diseases, the T cells of the immune system shut down in a process called T cell exhaustion. Without active T cells, which kill tumor cells, it’s impossible for our bodies to fight back against cancer. One of the biggest goals of immunotherapy is to reverse T cell exhaustion to boost the immune system’s ability to destroy cancerous cells.
