Mild hypothermia facilitates mitochondrial transfer from astrocytes to injured neurons during oxygen-glucose deprivation/reoxygenation.

Neurosci Lett 2021 May 7:135940. Epub 2021 May 7.

Department of Anesthesiology, Second Hospital of Hebei Medical University, Shijiazhuang, 050000, Hebei, China. Electronic address:

Mitochondrial dysfunction is now considered an important sign of neuronal death during cerebral ischemia/reperfusion (I/R) injury. Studies have shown that the transfer of mitochondria from astrocytes to injured neurons contributes to endogenous neuroprotection after stroke. Basic and clinical studies have shown that mild hypothermia exerts a clear protective effect on neurons after cerebral ischemic injury, but the role of mild hypothermia in this endogenous neuroprotective mechanism remains unclear.

The emerging role of FTY720 as a sphingosine 1-phosphate analog for the treatment of ischemic stroke: The cellular and molecular mechanisms.

Brain Behav 2021 May 10:e02179. Epub 2021 May 10.

Histomorphometry and Stereology Research Centre, Shiraz University of Medical Sciences, Shiraz, Iran.

Finding novel and effective drugs for the treatment of ischemic stroke is warranted because there is not a definitive treatment for this prevalent disease. Due to the relevance between the sphingosine 1-phosphate (S1P) receptor and several neurological diseases including ischemic stroke, it seems that fingolimod (FTY720), as an agonist of S1P receptor, can be a useful therapeutic strategy in these patients. FTY720 is the first oral drug approved by the US food and drug administration for the treatment of multiple sclerosis. Read More

Fasudil ameliorates cognitive deficits, oxidative stress and neuronal apoptosis via inhibiting ROCK/MAPK and activating Nrf2 signalling pathways in APP/PS1 mice.

Folia Neuropathol 2021 ;59(1):32-49

Department of Neurology, First Affiliated Hospital, Shanxi Medical University, Taiyuan, P.R. China.

Alzheimer's disease (AD) is a severe neurodegenerative disorder of the central nervous system (CNS) characterized by neuron loss and dementia. Previous abundant evidence demonstrates that the first critical step in the course of AD is the state of oxidative stress and the neuronal loss is closely related to the interaction of several signalling pathways. The neuroprotective efficacy of Rho-associated protein kinase (ROCK) inhibitor in the treatment of AD has been reported, but its exact mechanism has not been well elucidated. Read More

Addition of Drag-Reducing Polymers to Colloid Resuscitation Fluid Enhances Cerebral Microcirculation and Tissue Oxygenation After Traumatic Brain Injury Complicated by Hemorrhagic Shock.

Adv Exp Med Biol 2021 ;1269:283-288

Department of Neurosurgery, University of New Mexico, Albuquerque, NM, USA.

Hemorrhagic shock (HS) is a severe complication of traumatic brain injury (TBI) that doubles mortality due to severely compromised microvascular cerebral blood flow (mvCBF) and oxygen delivery reduction, as a result of hypotension. Volume expansion with resuscitation fluids (RF) for HS does not improve microvascular CBF (mvCBF); moreover, it aggravates brain edema. We showed that the addition of drag-reducing polymers (DRP) to crystalloid RF (lactated Ringer's) significantly improves mvCBF, oxygen supply, and neuronal survival in rats suffering TBI+HS.
