Platelets attach to lung type 2 innate lymphoid cells (ILC2s) expressing P-selectin glycoprotein ligand 1 and influence ILC2 function

Electron microscopy demonstrates that mouse lung ILC2 expressing PSGL-1 have platelets attached to their surface and that platelet depletion reduces lung ILC2 proliferation and Th2 cytokines suggesting ILC2 function is influenced by attachment to platelets.
