Abstract
Persisters are a rare sub-population of tumor cells that survive anti-cancer therapy and are thought to be a major cause of recurrence. These cells have been identified following both drug- and immune-therapy but are generally considered to be distinct entities. Since both pharmacological agents and immune cells often kill via apoptosis, we tested a hypothesis that both types of cells survive based on reduced mitochondrial apoptotic sensitivity, which in turn would yield a similar and reciprocal multi-agent resistant phenotype. Supporting this hypothesis, we indeed observed that IPCs acquired a reduced sensitivity to multiple drug classes and radiotherapy, suggesting non-immune mechanisms are important in the survival of cancer cells after immunotherapy. Likewise, DTPs developed not only a reduced sensitivity to multiple drug classes and radiotherapy, but also acquired a reduced sensitivity to T cell killing. Both IPCs and DTPs developed decreased sensitivity to mitochondrial apoptosis. A sub-population of IPCs downregulated antigen and upregulated PD-L1. Intriguingly, in the IPCs that didn’t employ these mechanisms of resistance, a greater decrease in sensitivity to mitochondrial apoptosis was observed, suggesting that the presence or absence of a resistance mechanism can exert selective pressures over the emergence of others. Targeting anti-apoptotic dependencies in persisters increased sensitivity to chemotherapy or CAR T therapy. These results suggest that common biological mechanisms underly survival of persisters, whether derived from immune or drug therapy, and offer an explanation for the acquired cross-resistance to these two types of therapies often observed in the clinic.

Highlights
-
Immunotherapy persister cells (IPCs) are less sensitive to drugs and radiation.
-
Drug tolerant persisters (DTPs) are less sensitive to radiation and CAR T cell attack.
-
IPCs and DTPs are less sensitive to mitochondrial apoptosis.
-
Targeting anti-apoptotic dependencies helps eliminate IPCs/DTPs.
