Metallophilic marginal zone macrophages are positioned strategically within the spleen to process internalized blood-borne materials. Mauvais et al. find that these CD169+ macrophages cross-prime CD8+ T cell responses to internalized antigens using a proteasome-independent pathway, contributing to antitumor immunity independently of type 1 conventional dendritic cells.
