From Abnormal Hippocampal Synaptic Plasticity in Down Syndrome Mouse Models to Cognitive Disability in Down Syndrome
Down syndrome (DS) is caused by the overexpression of genes on triplicated regions of human chromosome 21 (Hsa21). While the resulting physiological and behavioral phenotypes vary in their penetrance and severity, all individuals with DS have variable but significant levels of cognitive disability. At the core of cognitive processes is the phenomenon of synaptic plasticity, a functional change ...
متن کاملThe enteric nervous system.
T HE enteric nervous system is a collection of neu-rons in the gastrointestinal tract 1 that constitutes the " brain of the gut " and can function independently of the central nervous system. 2 This system controls the motility, 3,4 exocrine and endocrine secretions, 5 and microcirculation 6 of the gastrointestinal tract; it is also involved in regulating immune and inflammatory processes. 7 In...
متن کاملEnteric nervous system development in avian and zebrafish models.
Our current understanding of the developmental biology of the enteric nervous system (ENS) and the genesis of ENS diseases is founded almost entirely on studies using model systems. Although genetic studies in the mouse have been at the forefront of this field over the last 20 years or so, historically it was the easy accessibility of the chick embryo for experimental manipulations that allowed...
متن کاملThe human enteric nervous system.
Decades of work in animal models have demonstrated that the enteric nervous system (ENS) plays a key role in controlling gut functions. Recent advances made it possible to extend such studies to the ENS of man in health and even in disease. Such studies have already provided new insights into the pathophysiology of inflammatory and possibly functional bowel diseases. Studies on human ENS reveal...
متن کاملTransient Abnormal Myelopoiesis and AML in Down Syndrome: an Update
Children with constitutional trisomy 21 (Down syndrome (DS)) have a unique predisposition to develop myeloid leukaemia of Down syndrome (ML-DS). This disorder is preceded by a transient neonatal preleukaemic syndrome, transient abnormal myelopoiesis (TAM). TAM and ML-DS are caused by co-operation between trisomy 21, which itself perturbs fetal haematopoiesis and acquired mutations in the key ha...
