Skin immunisation activates an innate lymphoid cell-monocyte axis regulating CD8+ effector recruitment to mucosal tissues

Mucosal immunisation is important for initiating mucosal CD8+ T­cell responses but mucosal recruitment of protective CD8+ T cells can also be induced by skin immunisation. Here the authors examine the underlying mechanism and report a novel role for ILC1 recruiting CD8+ T cells to the mucosa after skin immunisation.
