Article Abstract
Microglia, the immune cells of the brain, play a major role in the maintenance of brain homeostasis and constantly screen the brain environment to detect any infection or damage. Once activated by a stimulus, microglial cells initiate an immune response followed by the resolution of brain inflammation. A failure or deviation in the housekeeping function of these guardian cells can lead to multiple diseases, including brain cancer and neurodegenerative diseases such as Alzheimer's disease (AD). A small number of studies have investigated the causal relation of both diseases, thereby revealing an inverse relationship where cancer patients have a reduced risk to develop AD and . In this review, we aim to shed light on the role of microglia in the fate to develop specifically glioma as one type of cancer or AD. We will examine the common and/or opposing genetic predisposition as well as associated pathways of these diseases to unravel a possible involvement of microglia in the occurrence of either disease. Lastly, a set of guidelines will be proposed for future research and diagnostics to clarify and improve the knowledge on the role of microglia in the decision toward one pathology or another.

The concept of the central nervous system (CNS) reserve emerged from the mismatch often observed between the extent of brain pathology and its clinical manifestations. The cognitive reserve reflects an "active" capacity, driven by the plasticity of CNS cellular components and shaped by experience, learning, and memory processes that increase resilience. We propose that neuroglial cells are central to defining this resilience and cognitive reserve.

Mutations in the human ADAR gene encoding adenosine deaminase acting on RNA 1 (ADAR1) cause Aicardi-Goutières syndrome 6 (AGS6); a severe auto-inflammatory encephalopathy with aberrant interferon (IFN) induction. AdarΔ2-13 null mutant mouse embryos lacking ADAR1 protein die with high levels of IFN-stimulated gene (ISG) transcripts. In Adar Mavs double mutants also lacking the Mitochondrial antiviral signaling (MAVS) adaptor, the aberrant IFN induction is prevented.

Background: Germinal matrix hemorrhage (GMH) is a common complication of premature infants with lifelong neurological consequences. Inflammation-mediated blood-brain barrier (BBB) disruption has been implicated as a main mechanism of secondary brain injury after GMH. The cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a crucial role in inflammation, yet its involvement in GMH pathophysiology remains unclear.

Introduction: Alzheimer's Disease (AD) is a common neurodegenerative disease among the elderly population. It has been posited that the onset and progression of AD are influenced by a combination of various factors. Occlusal support loss due to tooth loss has been reported to be a risk factor triggering cognitive dysfunction.

Matrix metalloproteinase 9 (MMP9) as a Zn2+-dependent matrix enzyme, not only maintains the integrity of the blood-brain barrier and synaptic plasticity, but also plays a key regulatory factor in peripheral and central nervous inflammation. This study aimed to investigate the effects of MMP9-mediated microglial polarization on surgery-induced neuroinflammation in aged rats and to provide novel targets for prevention and treatment of PND.
