Microglia are the primary immune cells of the brain and have the potential to both protect and contribute to neurological disease. Explore the molecular mechanisms that microglia use to mediate their biological effects in cerebral cytokinopathies.

The cytokines interleukin-6 (IL-6) and interferon-alpha (IFN-alpha) can cause a variety of neuroinflammatory diseases such as neuromyelitis optica and Aicardi-Goutières syndrome or neurological manifestations of systemic lupus erythematosus, respectively. They also are implicated in the development of a number of significant age-related neuropsychiatric disorders. However, an understanding of the mechanisms via which these cytokines mediate central nervous system (CNS) damage is unclear. Transgenic (TG) mouse models with CNS-restricted chronic production at pathophysiologically relevant levels of IL-6 or IFN-alpha replicate many of the key neuropathological and behavioural features of the human diseases, further highlighting the role of these cytokines as mediators of CNS injury and disease. Microglia, the innate immune cells of the CNS, are highly responsive cells that assume a variety of phenotypic states depending on the context of the surrounding environment. The activation of these cells is an early and pervasive feature of neurological and neuropsychiatric disease. Importantly, the actions and outcomes of transgenic IL-6 and IFN-alpha production in the brain are distinct, making these models also an ideal tool to study, and compare and contrast the responses and functions of microglia in the living brain. While the role of microglia in the pathogenesis of human disease is enigmatic, previous work by us implicate microglia as both a major target of and effector cell for IL-6 and IFN-alpha. Consequently, the overarching hypothesis driving this project is that microglia are central cellular effectors in many of the clinicopathological actions of IL-6 and IFN-alpha in the CNS.
