The Prevalence of Celiac Disease in Down syndrome Children with and without Congenital Heart Defects
Background The prevalence of celiac disease (CD) is remarkably varied in Down syndrome(DS)patientscompared with other diseases. This study aimed to assess celiac disease prevalence in Down syndrome children with and without congenital heart defects (CHD) and its comparison with controls. Materials and Methods This case-control study was performed at a single center on 132 participants in three...
متن کاملFrom 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 کاملDissecting Alzheimer disease in Down syndrome using mouse models
Down syndrome (DS) is a common genetic condition caused by the presence of three copies of chromosome 21 (trisomy 21). This greatly increases the risk of Alzheimer disease (AD), but although virtually all people with DS have AD neuropathology by 40 years of age, not all develop dementia. To dissect the genetic contribution of trisomy 21 to DS phenotypes including those relevant to AD, a range o...
متن کاملAltered intrinsic and network properties of neocortical neurons in the Ts65Dn mouse model of Down syndrome
All individuals with Down syndrome (DS) have a varying but significant degree of cognitive disability. Although hippocampal deficits clearly play an important role, behavioral studies also suggest that deficits within the neocortex contribute to somatosensory deficits and impaired cognition in DS. Using thalamocortical slices from the Ts65Dn mouse model of DS, we investigated the intrinsic and ...
متن کاملSMN-dependent intrinsic defects in Schwann cells in mouse models of spinal muscular atrophy.
Low levels of survival of motor neuron (SMN) protein lead to spinal muscular atrophy (SMA). The major pathological hallmark of SMA is a loss of lower motor neurons from spinal cord and peripheral nerve. However, recent studies have revealed pathological changes in other cells and tissues of the neuromuscular system. Here, we demonstrate intrinsic, SMN-dependent defects in Schwann cells in SMA. ...
