| Summary: | Memory T cells are essential for effective and durable immune responses, as they provide long-term immunological surveillance and rapid reactivity upon re-exposure to a given pathogen or cancer cell. In solid tumors, the immunosuppressive tumor microenvironment (TME) often hinders immune activation, making enhancing memory T cell formation and persistence a key goal in cancer immunotherapy. Novel strategies are exploring ways to support these memory T cells, including using Listeria monocytogenes as a cancer vaccine vector. Notably, L. monocytogenes has unique properties that make it an ideal candidate for this purpose: it is highly effective at activating T cells, promoting the differentiation and survival of memory T cells, and modulating the TME to favor immune cell function. Thus, by leveraging the ability of L. monocytogenes to induce a strong, sustained T-cell response, researchers aim to develop vaccines that provide lasting immunity against tumors, reduce recurrence rates, and improve patient survival outcomes. This mini-review highlights the potential of memory T cell-focused cancer immunotherapy and the promising role of L. monocytogenes in advancing these efforts. |
