The binding of cytokines to the gp130 receptor activates the STAT3, MEK/MAPK, and PI3K/Akt signalling pathways. To assess the relative importance of these pathways in promoting the survival of cytokine-dependent neurons, we conditionally inactivated STAT3 in mice and inhibited MEK, PI3K, and Akt in cultured neurons using pharmacological reagents and by(More)
Stunted growth is a major complication of chronic inflammation and recurrent infections in children. Systemic juvenile rheumatoid arthritis is a chronic inflammatory disorder characterized by markedly elevated circulating levels of IL-6 and stunted growth. In this study we found that NSE/hIL-6 transgenic mouse lines expressing high levels of circulating(More)
Growing evidence suggests that aberrant production of inflammatory cytokines within the central nervous system (CNS) contributes to the development of pathological conditions. To test the cause-effect relationship between the overproduction of interleukin-6 (IL-6) in the CNS and the onset of neuropathological changes, we have generated transgenic mice in(More)
Production of inflammatory cytokines, including tumor necrosis factor (TNF), interleukin-1 (IL-1) and interleukin-6 (IL-6), in the brain is increased in various diseases. To investigate the relationships between the effect of overproduction of IL-6 in the brain on central and peripheral production of TNF, IL-1 beta and IL-6 itself, we used transgenic mice(More)
