Mast cells reside in the brain and are an important source of inflammatory molecules. Aging is associated with increased number of mast cells (MCs) in the gut and in the brain. mast cells (n=6mice/group). We suggest that inhibition of mast cell activation can suppress neuroimmune responses and glial cell activation-associated neuroinflammation and neurodegeneration in TBI. 2021 Jan 18;11:617581. doi: 10.3389/fphar.2020.617581. Please enable it to take advantage of the complete set of features! Neurotrauma/TBI can cause primary damage to neurovascular and gliovascular units in the brain with subsequent neuroimmune and neuroinflammatory responses. During neuroinflammation, excessive levels of these mediators can influence neurogenesis, neurodegeneration and blood-brain barrier (BBB) permeability. Brain and Peripheral Atypical Inflammatory Mediators Potentiate Neuroinflammation and Neurodegeneration. There is growing interest is the presence of MCs in meningiomas, because of the conflicting reports with regard to the association of MCs with meningioma grade [24, 29, 30].Furthermore, there is increasing evidence suggesting MCs may stimulate neoplastic growth [31, 32], while others support a potential dual role of MCs contributing both to tumorigenesis … Front Neurosci.

Traumatic brain injury (TBI) is one of the major health problems worldwide that causes death or permanent disability through primary and secondary damages in the brain. Bazedoxifene protects cerebral autoregulation after traumatic brain injury and attenuates impairments in blood-brain barrier damage: involvement of anti-inflammatory pathways by blocking MAPK signaling. Biobehav. (2017) have suggested a framework for characterizing the role of mast cells in neuroinflammation: (1) Reciprocal interactions with microglia, astrocytes and neurons (Skaper et al., 2014) (2) Effects on blood-brain barrier permeability (Hendriksen et al., 2017) However, because of the contradictory results from experiments in rodents, very little is actually known about the exact role of mast cells in neuroinflammation. Growing evidence of mast cell–glia communication opens new perspectives for the development of therapies targeting neuroinflammation by differentially modulating activation of non‐neuronal cells that normally control neuronal sensitization – both peripherally and centrally. Mast cells are resident in the CNS [50] and are able to cross BBB from the periphery into the brain in neuroinflammation [19]. Microglia and mast cells (MCs), which are natural immune cells of the CNS, are mainly involved in the occur-rence of neuroinflammation(26). SARS-CoV-2 infection can cause psychological stress and neuroinflammation. Keywords: Neuroinflammation plays a key role in the occurrence and development of neurodegenerative diseases.
