Retina has long been considered less plastic than cortex or hippocampus, the very sites of experience-dependent plasticity. Now, we show that retinal development is responsive to the experience provided by an enriched environment (EE): the maturation of retinal acuity, which is a sensitive index of retinal circuitry development, is strongly accelerated in EE rats. This effect is present also in...

Brain derived neurotrophic factor (BDNF) is a member of the neurotrophin family and is widely expressed throughout the central nervous system (CNS). BDNF is involved in proliferation, differentiation, survival and death of neuronal and non-neuronal cells in the developing and adult CNS. The BDNF hypothesis of depression postulates that a reduction in BDNF is directly involved in the pathophysio...

BACKGROUND AND PURPOSE Niacin is the most effective medication in current clinical use for increasing high-density lipoprotein cholesterol. We tested the hypothesis that niacin treatment of stroke promotes synaptic plasticity and axon growth in the ischemic brain. METHODS Male Wistar rats were subjected to 2 hours of middle cerebral artery occlusion and treated with or without Niaspan (a prol...

Background and Purpose—Niacin is the most effective medication in current clinical use for increasing high-density lipoprotein cholesterol. We tested the hypothesis that niacin treatment of stroke promotes synaptic plasticity and axon growth in the ischemic brain. Methods—Male Wistar rats were subjected to 2 hours of middle cerebral artery occlusion and treated with or without Niaspan (a prolon...

BACKGROUND Visceral hypersensitivity is a complex pathophysiological paradigm with unclear mechanisms. Primary afferent neuronal plasticity marked by alterations in neuroactive compounds such as calcitonin gene-related peptide is suggested to underlie the heightened sensory responses. Signal transduction that leads to calcitonin gene-related peptide expression thereby sensory neuroplasticity du...

Recent studies revealed that BDNF-TrkB pathway plays an important role in cardiac microvascular endothelial cells (CMECs) mediated myocardial angiogenesis. Single-cell analysis is a powerful tool for studying gene expression in individuals since cellular heterogeneity and dynamic microenvironments which individual cell will experience. Little is currently known about the expression of BDNF and ...

The tyrosine kinase receptor trkB is thought to mediate the biological actions of brain-derived neurotrophic factor. This receptor is expressed by a large variety of neurons during development. Truncated trkB molecules lacking the tyrosine kinase domain have also been described, but their functions remain elusive. In order to gain insight into their role, we studied the pattern of expression an...
