Metallothioneins (MTs) constitute a family of proteins characterized by a high heavy metal [Zn(II), Cu(I)] content and also by an unusual cysteine abundance. Mammalian MTs are comprised of four major isoforms designated MT-1 trough MT-4. MT-1 and MT-2 are expressed in most tissues including the brain, whereas MT-3 (also called growth inhibitory factor) and(More)
In addition to detrimental inflammation, widespread axon degeneration is an important feature of multiple sclerosis (MS) pathology and a major correlate for permanent clinical deficits. Thus, treatments that combine immunomodulatory and neuroprotective effects are beneficial for MS. Using myelin oligodendrocyte glycoprotein peptide 35-55 (MOG)-induced(More)
Expression of brown adipose tissue (BAT) associated proteins like uncoupling protein 1 (UCP1) in inguinal WAT (iWAT) has been suggested to alter iWAT metabolism. The aim of this study was to investigate the role of interleukin-6 (IL-6) in exercise training and cold exposure-induced iWAT UCP1 expression. The effect of daily intraperitoneal injections of IL-6(More)
The role of interleukin-6 in hippocampal tissue damage after injection with kainic acid, a rigid glutamate analogue inducing epileptic seizures, has been studied by means of interleukin-6 null mice. At 35mg/kg, kainic acid induced convulsions in both control (75%) and interleukin-6 null (100%) mice, and caused a significant mortality (62%) only in the(More)
The effects of previous chronic immobilization stress on the physiological responses of male rats to a novel chronic stressor (shock) were studied. Previous chronic exposure to immobilization reduced adrenocorticotropin (ACTH) and lactate responses to acute immobilization stress without altering the response to a novel acute stressor (tail shock). When(More)
Metallothioneins (MTs) are major zinc binding proteins in the CNS that could be involved in the control of zinc metabolism as well as in protection against oxidative stress. Mice lacking MT-I and MT-II (MT-I + II deficient) because of targeted gene inactivation were injected with kainic acid (KA), a potent convulsive agent, to examine the neurobiological(More)
Experimental autoimmune encephalomyelitis (EAE) is an induced inflammatory and demyelinating disease of the central nervous system which shares many clinical and pathological features with and is considered the animal model of multiple sclerosis. There is extensive evidence that EAE is a Th1 disease eliciting secretion of proinflammatory cytokines like(More)
Metallothionein-I+II (MT-I+II) are antioxidant, neuroprotective proteins, and in this report we have examined their roles during experimental autoimmune encephalomyelitis (EAE) by comparing MT-I+II-knock-out (MTKO) and wild-type mice. We herewith show that EAE susceptibility is higher in MTKO mice relatively to wild-type mice, and that the inflammatory(More)
Metallothionein-III is a low molecular weight, heavy-metal binding protein expressed mainly in the central nervous system. First identified as a growth inhibitory factor (GIF) of rat cortical neurons in vitro, it has subsequently been shown to be a member of the metallothionein (MT) gene family and renamed as MT-III. In this study we have raised polyclonal(More)
To characterize the physiological role of metallothioneins I and II (MT-I+II) in the brain, we have examined the chronological effects of a freeze injury to the cortex in normal and MT-I+II null mice. In normal mice, microglia/macrophage activation and astrocytosis were observed in the areas surrounding the lesion site, peaking at approximately 1 and 3 d(More)
