adipose tissue
• norepinephrine-treated cultured brown adipocytes fail to exhibit an increase in basal oxygen consumption unlike wild-type cells

immune system
• there is a slight reduction in Th1 T cell production after infection with Listera monocytogenes
• NK cells produce less IFN-gamma after stimulation with IL-12 and IL-18
• T cells cultured under Th1 polarizing conditions produce half to two-thirds less IFN-gamma when activated
• reactivated Th1 T cells are resistant to activation-induced cell death when cultured with low doses of anti-CD3 antibodies
• ear swelling responses to dinitrofluorobenzene challenge are half to a two-thirds less than in wild-type controls
• T cells cultured under Th1 polarizing conditions produce half to two-thirds less IFN-gamma when activated (J:69475)
• NK cells produce less IFN-gamma after stimulation with IL-12 and IL-18 (J:87396)
