Chemotherapy is still one of the most widely used anticancer therapies. It is mostly about inhibiting the proliferation of rapidly dividing cells, so it is not selective for tumor cells. As a result, many undesirable side effects are associated with chemotherapy. The disadvantageous properties of chemotherapeutics can be largely eliminated by using conjugates of polymers with low molecular weight drugs. An example of such a conjugate is a doxorubicin-linked HPMA polymer. In addition to the properties obtained by polymer binding, such as achieving solubility in aqueous solutions, reducing systemic toxicity, increasing the maximum tolerated dose, or passive targeting by the EPR effect, the fact that doxorubicin induces immunogenic cell death is used in therapy with this drug. It has already been shown that after complete cure of the experimental mice with polymeric conjugates of HPMA with doxorubicin, some mice develop long-term resistance to re-inoculation with a lethal dose of tumor cells. Resistance is specific to the particular line of tumor cells from which the mouse was cured, and CD8+ cytotoxic T cells and IFNγ play an important role. In this work, we monitored changes in the proportion of immune populations and their activation markers after treatment with HPMA-based polymers with doxorubicin...
