Nasal glial heterotopia Nasal glial heterotopia Nasal glial heterotopia refers to congenital malformations of displaced normal, mature glial tissue, which are no longer in continuity with an intracranial component. This is distinctly different from an encephalocele, which is a herniation of brain tissue and/or leptomeninges, that develops through a defect in the skull, where there is a continuity with the cranial cavity. While nasal glial heterotopia (NGH) is the preferred term, synonyms have included nasal glioma. However, this term is to be discouraged, as it implies a neoplasm or tumor, which it is not. By definition, nasal glial heterotopia is a specific type
Satellite glial cell has been discovered that this receptor has an antagonist in the form of A-317491, which, when present, has the ability to reduce both the evoked and unprompted firing of various classes of spinal neurons, as well as to inhibit release of IL-1β. However, the outside influences of receptors P2X3 and P2Y1 are believed to complicate the interactions between P2X7 and its antagonist, making it a non-ideal target when using pharmacological strategy. P2Y receptors are also found on both neurons and glial cells. Their role is less clear than that of the P2X receptors, but it has been noted they have
