Exogenous induction of cerebral beta-amyloidogenesis is governed by agent and host

Peter Frey, Tristan Bolmont, Paolo Paganetti

Protein aggregation is an established pathogenic mechanism in Alzheimer's disease, but little is known about the initiation of this process in vivo. Intracerebral injection of dilute, amyloid-beta (A beta)-containing brain extracts from humans with Alzheim ...

Glucocorticoid involvement in memory formation in a rat model for traumatic memory

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Contextual fear conditioning under training conditions involving high stressor intensities has been proposed as an animal model for traumatic memories. The strength of memory for this task has been related to the intensity of the conditioning stressor and ...

In vivo measurements of brain glucose transport using the reversible michaelis-menten model and simultaneous measurements of cerebral blood flow changes during hypoglycemia

Rolf Gruetter

Glucose is the major substrate that sustains normal brain function. When the brain glucose concentration approaches zero, glucose transport across the blood-brain barrier becomes rate limiting for metabolism during, for example, increased metabolic activit ...

Opposite effects on NCAM expression in the rat frontal cortex induced by acute vs. chronic corticosterone treatments

Maria del Carmen Sandi Perez

The temporal pattern of exposure to glucocorticoids has been reported to be a critical factor in determining the outcome of glucocorticoid actions at the brain. In this work, the effects of different regimes of subcutaneous corticosterone administration (a ...

Glucocorticoids induce the expression of the leptin gene through a non-classical mechanism of transcriptional activation

Johan Auwerx

Leptin is a hormone which is produced in adipose tissue and which plays a role in the regulation of energy homeostasis. The expression of the ob gene, encoding leptin, is under multi-hormonal control. We have shown previously that high doses of glucocortic ...

The role and mechanisms of action of glucocorticoid involvement in memory storage

Maria del Carmen Sandi Perez

Adrenal steroid hormones modulate learning and memory processes by interacting with specific glucocorticoid receptors at different brain areas. In this article, certain components of the physiological response to stress elicited by learning situations are ...

Transcriptional induction of rat liver apolipoprotein A-I gene expression by glucocorticoids requires the glucocorticoid receptor and a labile cell-specific protein

Johan Auwerx

Treatment with glucocorticoids increases the concentration of plasma high-density lipoprotein (HDL), which is inversely correlated to the development of atherosclerosis. Previously, we demonstrated that repeated administration of glucocorticoids increases ...

Corticosteroid receptor antagonists are amnestic for passive avoidance learning in day-old chicks

Maria del Carmen Sandi Perez

Glucocorticoids can modulate behavioural processes and neural plasticity. They are released during learning situations and can trigger neural actions through binding to brain receptors. We hypothesized that a glucocorticoid action could play a critical rol ...

Corticosterone enhances long-term retention in one-day-old chicks trained in a weak passive avoidance learning paradigm

Maria del Carmen Sandi Perez

Glucocorticoids are released during learning situations and can trigger neural actions through binding to receptors in different brain areas. The possible role of a glucocorticoid action in long-term memory formation was studied, in day-old chicks, by usin ...

Activity of the hypothalamic-pituitary-adrenal axis in mice selected for left- or right-handedness

Maria del Carmen Sandi Perez

Asymmetry in brain modulation of the immune system has been previously described. In mice, paw preference has been shown to be associated with immune reactivity but the mechanisms involved in such an association are not yet known. The autonomic nervous sys ...
