av AK Johnsson · 2011 — the principal mechanism of recycling of the synaptic vesicles, which is interesting actin is distinguished by three phases; a lag phase referred to as the nucleation In general, profilins interact with actin and with at least one actin related protein though at lower levels in brain, heart, skeletal muscle and pancreas (Buss.

Notably, these different Aβ42-containing structures, small vesicles at the synapse and larger nonsynaptic bodies, could only be resolved and differentiated by using STED. Our findings thus demonstrate that super-resolution microscopy is required both to determine the synaptic localization of Aβ42 and to distinguish between different types of Aβ42 structures in the neuronal compartments.

Such cells with tumour initiating properties that could be prevalent and only rarely activated by injury [147] or inflammation [77] , similarly to transformed cells observed in other tumour/organ sites [148] . Extracellular vesicles are involved in a great variety of physiological events occurring in the nervous system, such as cross talk among neurons and glial cells in synapse development and function, integrated neuronal plasticity, neuronal-glial metabolic exchanges, and synthesis and dynamic renewal of myelin. Many of these EV-mediated processes depend on the exchange of proteins, mRNAs, and Primary brain vesicle definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.

Generally, neurotransmitters are stored in synaptic vesicles that undergo recycling at synaptic sites (1, 2).

The rostral region of vertebrate neural tubes develops into three morphologically distinct swellings or the primary brain vesicles by differential proliferation of neuroepithelial territories: the forebrain, midbrain, and hind brain (Ishikawa et al., 2012), each of brain vesicles may be composed of several smaller repetitive units known as neuromeres (Nieuwenhuys, 1998).

The neural tube differentiates into the primitive brain and the spinal cord. At about 7 to 8 gestational weeks, the primary vesicles of the brain are formed and can

The cerebrum and brainstem arise from the rostral neural tube. These regions expand and constrict to form the three primary brain vesicles: Forebrain/Prosencephalon, Midbrain/Mesencephalon, and Hindbrain/Rhombencephalon. As development continues, the three primary vesicles give rise to five secondary brain vesicles: Telencephalon, Diencephalon, Abstract.

In the fifth week of development, swellings appear at the cranial end of the neural tube. Three primitive vesicles appear first, and subsequently these develop into five secondary vesicles.
