By contrast, Teff cell expansion was only marginally affected in both the tdLN and the spleen, with negligible effect in the tumour (Fig. 3c and Extended Data Fig. 5d,e), showing that late antigen presentation by cDC1 cells in the tdLN is necessary for maintaining an expanded population of antigen-specific SLAMF6+ TSL cells. Here, MPPE1 is linked to neoplasm.
