For other immune cells, CD45 on granulocytes showed neuroprotective effects (IVW: OR 0.93, 95% CI 0.88–1.00; p = 0.037), while HLA DR on CD33dim HLA DR+ CD11b– (IVW: OR 1.05, 95% CI 1.01–1.10; p = 0.025) and CD62L on CD62L+ plasmacytoid dendritic cells (IVW: OR 1.06, 95% CI 1.00–1.13; p = 0.042) were linked with increased ischemic stroke risk. The gene discussed is SELL; the disease is ischemic stroke.
