Figure 1From: An in vivo animal study assessing long-term changes in hypothalamic cytokines following perinatal exposure to a chemical mixture based on Arctic maternal body burden Hypothalamic IL-1β changes in offspring at PND 145-147 (A) and in animals at PND 208-212 that received LPS immediately before sacrifice (B). All animals were exposed to the chemical mixture, PCBs, MeHg or MeHg+PCBs during gestation and lactation.. n = 8-10Back to article page
