Microglial action in glioma: A boon turns bane

Microglia has the potential to shape the neuroimmune defense with vast array of functional attributes. The cells prime infiltrated lymphocytes to retain their effector functions, play crucial role in controlling microenvironmental milieu and significantly participate in glioma. Reports demonstrate microglial accumulation in glioma and predict their assistance in glioma growth and spreading. Clarification of the ‘double-edged’ appearance of microglia is necessary to unfold its role in glioma biology. In this article the interpretation of microglial activities has been attempted to reveal their actual function in glioma. Contrary to the trendy acceptance of its glioma promoting infamy accumulated evidences make an effort to view the state of affairs in favor of the cell. Critical scrutiny indicates that microglial immune assaults are intended to demolish the neoplastic cells in brain. But the weaponry of microglia has been tactically utilized by glioma in their favor as the survival strategy. Hence the defender appears as enemy in advanced glioma.
