Autophagy in neuroinflammation after traumatic brain injury

Neural Regeneration research 2024年第5期19卷 951-952页

作者： Chinmoy Sarkar Marta M.Lipinski Shock Trauma and Anesthesiology Research(STAR)CenterDepartment of AnesthesiologyUniversity of Maryland School of MedicineBaltimoreMDUSA Department of Anatomy and Neurobiology University of Maryland School of MedicineBaltimoreMDUSA

traumatic brain injury(TBI)is an acquired injury of the brain caused by the impact of external forces on the brain(Maas et al.,2008).It is a major cause of death and disability among people of all ages(Maas et al.,2008).The primary mechanical injury to the brain initiates a cascade of secondary biochemical events that lead to acute and chronic neurodegeneration and activation of inflammatory pathways(Maas et al.,2008).Both brain-resident microglia and blood-derived myeloid cells-macrophages and monocytes that infiltrate the brain due to injury-induced blood-brain barrier damage,contribute to the inflammatory responses after TBI(Morganti et al.,2015).

To the Editor:Air pollution can lead to respiratory and cardiovascular diseases(CVDs),and its impact on human health is very *** particles less than 0.1µm can pass through the blood brain barrier,reach the brain,and enter the central nervous system,causing physiological and pathological changes.A study shows that long-term exposure to fine particulate matter(PM_(2.5))will increase the risk of CVDs among Chinese residents.^([1])Another study found that a short time exposure to low concentrations of air pollutants may also lead to the onset of acute coronary syndrome within one hour.^([2])A meta-analysis based on seven databases showed that environmental air pollution was positively correlated with elevated blood pressure and hypertension.^([3])Mounting evidence indicates that air pollution can cause cardiovascular and cerebrovascular diseases and affect human health furtherly.
