The CST forms the longest axonal projection in the mammalian central nervous system (CNS). The development of CST axons is the latest ...

... Since the amino acid sequences of BMP4 and BMP2 are very similar, we first investigated whether the antibody (NCL-BMP4) can discriminate between them using ELISA method. As shown in Fig. 1A and B, the antibody could specifically recognize only BMP4 protein in a dose-dependent manner. In addition, we ...

Aging brain

Age is a major risk factor for most common neurodegenerative diseases, including Mild cognitive impairment, Alzheimer's disease, cerebrovascular disease, Parkinson's disease and Lou Gehrig's disease. While much research has focused on diseases of aging, there are few informative studies on the molecular biology of the aging brain (usually spelled ageing brain in British English) in the absence of neurodegenerative disease or the neuropsychological profile of healthy older adults. However, research does suggest that the aging process is associated with several structural, chemical, and functional changes in the brain as well as a host of neurocognitive changes. Recent reports in model organisms suggest that as organisms age, there are distinct changes in the expression of genes at the single neuron level. This page is devoted to reviewing the changes associated with healthy aging.
