Streptomyces coelicolor is a representative of the group of soil-dwelling, filamentous bacteria responsible for producing most natural antibiotics used in human and veterinary medicine. Here we report the 8,667,507 base pair linear chromosome of this organism, containing the largest number of genes so far discovered in a bacterium. The 7,825 predicted genes(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)
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)
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)
Since the seminal discoveries of Bert Vallee regarding zinc and metallothioneins (MTs) more than 50 years ago, thousands of studies have been published concerning this fascinating story. One of the most active areas of research is the involvement of these proteins in the inflammatory response in general, and in neuroinflammation in particular. We describe(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 balance between trophic factors and inhibitory molecules is likely to determine the outcome of neural tissue damage. The growth inhibitory factor (GIF), a member of the metallothionein family of proteins named metallothionein-III (MT-III), has been suggested to play an important role in tissue repair after adult brain injury. Because no information is(More)
Cytokines, such as tumour necrosis factor (TNF)-alpha and lymphotoxin-alpha, have been described widely to play important roles in the brain in physiologic conditions and after traumatic injury. However, the exact mechanisms involved in their function have not been fully elucidated. We give some insight on their role by using animals lacking either Type 1(More)
Experimental autoimmune encephalomyelitis (EAE) is an animal model for the human demyelinating disease multiple sclerosis (MS). EAE and MS are characterized by significant inflammation, demyelination, neuroglial damage, and cell death. Metallothionein-I and -II (MT-I + II) are antiinflammatory and neuroprotective proteins that are expressed during EAE and(More)
The effect of CNS-targeted IL-6 gene expression has been thoroughly investigated in the otherwise nonperturbed brain but not following brain injury. Here we examined the impact of astrocyte-targeted IL-6 production in a traumatic brain injury (cryolesion) model using GFAP-IL6 transgenic mice. This study demonstrated that transgenic IL-6 production(More)
