Additionally, anti‐IL‐17A antibody may also interfere with neutrophil recruitment to AD brain through inhibition of IL‐8 production by neutrophils, because IL‐17A, which is produced by neutrophils (Keijsers, Joosten, Erp, Koenen, & Kerkhof, 2014), stimulates various cells, including microvascular endothelial cells, to produce IL‐8 (Linden, 2001; Roussel et al., 2010). The gene discussed is CXCL8; the disease is Alzheimer disease.
