CD4/CD8 T cells in cancer ascites not only express inhibitory receptors (IRs) such as PD1 more frequently than CD4/CD8 T cells in peripheral blood due to long-term exposure to cancer cells (i.e., cancer antigens), but also are considered to be in a 'more exhausted' state. CD4/CD8 T cells in the exhausted stage are refractory to immune-checkpoint-blockade (ICB), which suppresses IRs, and cannot be expected to respond to ICB. The present study,
(1) Development of a novel treatment for patients with refractory cancer ascites by inducing reactivation of exhausted CD4/CD8 T cells by culturing T cells in ascites fluid with a demethylating agent.
(2) Development of a new treatment for patients with refractory cancerous ascites by reactivation of CD4/CD8 T cells using CRISPR/Cas13 technology to suppress PD1 mRNA in T cells.
(3) Development of T cell staging technology by detection of methylation pattern that enables prediction of T cell activation status.
Efficacy
Confirmation of the efficacy of a novel treatment for patients with refractory cancer ascites by inducing the reactivation of exhausted CD4/CD8 T cells by culturing T cells in ascites fluid with a demethylating agent.
