Interleukin-1β (IL-1β) mediates many of the behavioral responses to infection and inflammation, and IL-1β-converting enzyme (ICE) processes intracellular IL-1β, leading to its maturation and secretion. Here we demonstrate that intracerebroventricular injections of lipopolysaccharide (LPS) produced a greater reduction in both food intake and food-motivated behavior in wild-type compared with ICE...
Intrathecal methotrexate in children with leukemia is known to cause seizures, dementia, leukoencephalopathy and cognitive dysfunction. To investigate the role of brain amines in cognitive dysfunction, male Wistar rats were given multiple intracerebroventricular injections of methotrexate. Our earlier studies in this regard revealed disruption of brain monoamines in hippocampus with severe cyto...
The purpose of this study was to investigate the anti-inflammatory properties of intracerebroventricular met-enkephalin (met-enk) administration in an animal model of arthritis. Adjuvant arthritis was induced in rats by intradermal inoculation of mycobacterium butyricum and the effects of intraventricular met-enk+thiorphan (enkephalinase inhibitor) were studied. Treatment was initiated either s...
This study evaluated the participation of mu-opioid-receptor activation in body temperature (T(b)) during normal and febrile conditions (including activation of heat conservation mechanisms) and in different pathways of LPS-induced fever. The intracerebroventricular treatment of male Wistar rats with the selective opioid mu-receptor-antagonist cyclic d-Phe-Cys-Try-d-Trp-Arg-Thr-Pen-Thr-NH(2) (C...
Central dopaminergic mechanisms involved in the regulation of plasma aldosterone concentration were investigated in 16 conscious sheep following Na depletion with intramuscularly administered furosemide. Intracerebroventricular infusion of dopamine (20 micrograms/min) decreased plasma aldosterone significantly to 52 +/- 8% of basal level and increased plasma renin activity (PRA) significantly t...
We previously demonstrated that dorsal hippocampal extracellular signal-regulated kinase (ERK) activation is necessary for 17beta-estradiol (E(2)) to enhance novel object recognition in young ovariectomized mice (Fernandez et al., 2008). Here, we asked whether E(2) has similar memory-enhancing effects in middle-aged and aged ovariectomized mice, and whether these effects depend on ERK and phosp...
