Pericytes and renal mesangial cells are some examples of modified myofibroblast-like cells. Myofibroblasts may interfere with the propagation of electrical signals [5] controlling heart rhythm, [6] leading to arrhythmia in both patients who have suffered a heart attack and in foetuses. Ursodiol is a promising drug for this condition. [7]
Pancreatic stellate cells (PaSCs) are classified as myofibroblast-like cells that are located in exocrine regions of the pancreas. [ 1 ] [ 2 ] PaSCs are mediated by paracrine and autocrine stimuli and share similarities with the hepatic stellate cell . [ 2 ]
Histopathologically, FMTs consist of neoplastic connective tissue cells which have differented into cells that have microscopic appearances resembling fibroblasts and/or myofibroblasts. The fibroblastic cells are characterized as spindle-shaped cells with inconspicuous nucleoli that express vimentin , an intracellular protein typically found in ...
Such cells have been called hybrid brain cells because they exhibit both neuron-like and glial-like properties. Unlike traditional neurons , these cells not only transmit electrical signals but also provide supportive roles typically associated with glial cells , such as regulating the brain's extracellular environment and maintaining overall ...
Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
PET image of the human brain showing energy consumption. The brain consumes up to 20% of the energy used by the human body, more than any other organ. [131] In humans, blood glucose is the primary source of energy for most cells and is critical for normal function in a number of tissues, including the brain. [132]
Concerns have grown since the National Institutes of Health published a study in May finding that, on average, 91 brain samples contained roughly 10 to 20 times more than other organs (e.g., the ...
The widespread connections of the nucleus basalis with other parts of the brain indicate that it is likely to have an important modulatory influence on brain function. [3] Studies of the firing patterns of nucleus basalis neurons in nonhuman primates indicate that the cells are associated with arousing stimuli, both positive (appetitive) and ...
