Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

Magnesium deficiency causes neurogenic inflammation in a rat model. Researchers have theorized that since substance P which appears at day five of induced magnesium deficiency, is known to stimulate in turn the production of other inflammatory cytokines including IL-1, Interleukin 6 (IL-6), and TNF-alpha (TNFα), which begin a sharp rise at day 12, substance P is a key in the path from ...
Acute neuroinflammation is generally caused by some neuronal injury after which microglia migrate to the injured site engulfing dead cells and debris. [1] The term neuroinflammation generally refers to more chronic, sustained injury when the responses of microglial cells contribute to and expand the neurodestructive effects, worsening the ...
Neuritis (/ nj ʊəˈr aɪ t ɪ s /), from the Greek νεῦρον), [1] is inflammation of a nerve [2] or the general inflammation of the peripheral nervous system.Inflammation, and frequently concomitant demyelination, [3] [4] [5] cause impaired transmission of neural signals and leads to aberrant nerve function.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
The sensome can also play a role in neurodevelopment. Early-life brain infection results in microglia that are hypersensitive to later immune stimuli. When exposed to infection, there is an upregulation of sensome genes involved in neuroinflammation and a downregulation of genes that are involved with neuroplasticity. [47]
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.
ROS, alone, cause more than 20 types of DNA damage. [51] Oxidative DNA damages cause both mutations [52] and epigenetic alterations. [53] [47] [54] RNS also cause mutagenic DNA damages. [55] A normal cell may undergo carcinogenesis to become a cancer cell if it is frequently subjected to DNA damage during long periods of chronic inflammation.
