ID: “Immune cells and cytokinesplay critical roles in the development of colitis.....exposure toBAC and BET.....increased infiltration of immunecells—including leukocytes (CD45þ), macrophages (CD45þ, F4/80þ), and neutrophils (CD45þ, Gr1þ)—into colon tissues.....exposure to BAC andBET.....increased concentrations of interleukin 6(IL-6), a proinflammatory cytokine, in colonic explant.....qRT-PCR analysisshowed that exposure to BAC increased gene expression of Il-6in colon tissues” [87]. The gene discussed is IL6; the disease is colitis.
