The Health Hazards of Volcanoes: First Evidence of Neuroinflammation in the Hippocampus of Mice Exposed to Active Volcanic Surroundings

<div>Immunofluorescence assay of TNF<i>α</i> in the dentate gyrus of rodents inhabiting (a) Furnas village and (b) Rabo de Peixe. Accumulation of TNF<i>α</i> is evident inside some cells located in the subgranular zone, compatible with neural stem cells (inset, white arrows) and in the hilum, compatible with mossy cells (inset, arrowhead). GL: granular layer; PL: polymorphic layer. Scale bar: 50 <i>μ</i>m.</div>
