FLT3LG and neoplasm: Importantly, dynamic monitoring of circulating CD44hiCD8+ memory T cells and TEM in mice treated with DEXP&A&N and Flt3L at different time points exhibited stabilized pool of memory T cells, with a decline of TEM on day 100 after re-challenge (Fig. 7f, g) [42], supporting the conclusion that sustainable immunological memory responses curtailed tumor re-challenge.
