Neural top–down control of physiology concerns the direct regulation by the brain of physiological functions (in addition to smooth muscle and glandular ones). Cellular functions include the immune system’s production of T-lymphocytes and antibodies, and nonimmune related homeostatic functions such as liver gluconeogenesis, sodium reabsorption, osmoregulation, and brown adipose tissue ...
Brain perfusion is essential for life, since the brain has a high metabolic demand. By means of cerebral autoregulation, the body is able to deliver sufficient blood containing oxygen and nutrients to the brain tissue for this metabolic need, and remove CO 2 and other waste products.
The key cellular components of the neuroimmune system are glial cells, including astrocytes, microglia, and oligodendrocytes. [1] [2] [5] Unlike other hematopoietic cells of the peripheral immune system, mast cells naturally occur in the brain where they mediate interactions between gut microbes, the immune system, and the central nervous system as part of the microbiota–gut–brain axis.
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
miR-129 seems to have a tissue specific expression pattern localised to the brain in normal humans. This finding was identified initially by microarray experimentation with mouse tissue (and more specifically to the cerebellum) [1] which was subsequently validated by the expression profiling in human tissue. However, expression in normal brain ...
This release also has a physiological role in the regulation of glutamatergic metabotropic receptors and control of other neurotransmitters. [10] It has been demonstrated that, in the embryonic retina, Xc- exchanger is responsible for 50% of total glutamate uptake, representing a Sodium-Independent system within this tissue.
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
Due to the specificity of genetic regulation mechanisms within each tissue, many experiments would need to be performed to determine the tissue specific nature of each loci association and how these associations differ between tissue types. [3] Co-regulation results from a regulatory mechanism controlling the expression of more than one loci at ...
