Research Progress on the Correlation between Neuroinflammation and Brain Iron Metabolism after Intracerebral Hemorrhage

Abstract: Intracerebral hemorrhage refers to bleeding caused by non-traumatic rupturing of blood vessels within the brain, which is a serious neurological disorder. Its main pathophysiological characteristics include massive bleeding and neuron death, which impair the neuroimmune system and severely affect the patient’s prognosis. Iron ion homeostasis is crucial for maintaining normal neurological function. However, following intracerebral hemorrhage, disrupted iron metabolism leads to iron accumulation in the brain. Excessive iron participates in neuroinflammatory responses by activating inflammatory signaling pathways and regulating the function of inflammatory cells, while neuroinflammatory cells also participate in regulating the transportation and storage of iron ions. The interaction between the two exacerbates neurol damage. This article reviews the progress of research on the correlation between neuroinflammation and brain iron metabolism after intracerebral hemorrhage, aiming to provide a reference for the clinical treatment of intracerebral hemorrhage.
