AbstractBackgroundβ-Amyloid precursor protein (APP) has been reported to play a role in the outgrowth of neurites from cultured neurons. Both cell-surface APP and its soluble, ectodomain cleavage product (APPs-α) have been implicated in regulating the length and branching of neurites in a varie...... hiện toàn bộ

AbstractTelencephalic patterning centers, defined by the discrete expression domains of distinct morphogens, Fgf s in the commissural plate (CoP), Wnt s and Bmp s in the cortical hem, and a ventral domain of Sonic hedgehog (Shh), are postulated to ...... hiện toàn bộ

AbstractBackgroundCell surface heparan sulfate proteoglycans (HSPGs) act as co-receptors for multiple families of growth factors that regulate animal cell proliferation, differentiation and patterning. Elimination of heparan sulfate during brain development is known to produce severe structural abnormalities. Here we investigate t...... hiện toàn bộ

AbstractBackgroundNewts have the remarkable ability to regenerate their spinal cords as adults. Their spinal cords regenerate with the regenerating tail after tail amputation, as well as after a gap-inducing spinal cord injury (SCI), such as a complete transection. While most studies on newt sp...... hiện toàn bộ

AbstractBackgroundThe trajectory of corticospinal tract (CST) axons from cortex to spinal cord involves a succession of choice points, each of which is controlled by multiple guidance molecules. To assess the involvement of transmembrane semaphorins and their plexin receptors in the guidance of...... hiện toàn bộ
AbstractBackgroundNeurons receive excitatory synaptic inputs that are distributed across their dendritic arbors at densities and with spatial patterns that influence their output. How specific synaptic distributions are attained during development is not well understood. The distribution of glutamatergic inputs across the dendriti...... hiện toàn bộ

AbstractBackgroundFunctional lateralization is a conserved feature of the central nervous system (CNS). However, underlying left-right asymmetries within neural circuitry and the mechanisms by which they develop are poorly described.

AbstractBackgroundIn contrast to mammals, amphibians, such as adult urodeles (for example, newts) and anuran larvae (for example, Xenopus) can regenerate their spinal cord after injury. However, the cellular and molecular mechanisms involved in this process are still ...... hiện toàn bộ
AbstractBackgroundUnlike mammals, zebrafish exhibits extensive neural regeneration after injury in adult stages of its lifetime due to the neurogenic activity of the radial glial cells. However, the genes involved in the regenerative neurogenesis response of the zebrafish brain are largely unkn...... hiện toàn bộ
