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]
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 ...
Evidence for the role of astrocytes in the integration and processing of synaptic integration presents itself in a number of ways: Astrocytes are excitable cells: In response to stimuli from any of the three components of the tripartite synapse, astrocytes are capable of producing transient changes in their intracellular calcium concentrations through release of calcium stores from the ...
Meningeal cells are specialized fibroblast-like cells that surround the CNS and major blood vessels. They have been found to co-operate with astrocytes in the initial formation of the glia limitans during development and participate in its continued maintenance throughout life.
In general, neuroglial cells are smaller than neurons. There are approximately 85 billion glia cells in the human brain, [8] about the same number as neurons. [8] Glial cells make up about half the total volume of the brain and spinal cord. [27] The glia to neuron-ratio varies from one part of the brain to another.
Additionally, over an 8-year period, from 2016 to 2024, the brain samples showed a 50% higher total of microplastics — which reflected a similar increase in the rate of microplastics found in ...
Pyramidal neurons, like other neurons, have numerous voltage-gated ion channels. In pyramidal cells, there is an abundance of Na +, Ca 2+, and K + channels in the dendrites, and some channels in the soma. [9] [10] Ion channels within pyramidal cell dendrites have different properties from the same ion channel type within the pyramidal cell soma.
The study also looked at brain samples from individuals with dementia and found higher levels of microplastics, which it said may have accumulated in blood vessel walls and immune cells.
