Application

Beas2B human lung epithelial cells were treated with TGN-020 to study the effect on cigarette smoke extracts-induced CCN1 secretion.

Biochem/physiol Actions

TGN-020 is an inhibitor of Aquaporin 4 (AQP4), the most abundant water channel in brain. Aquaporins (AQPs) are water channels required for maintaining fluid homeostasis and enabling water movement across barrier membranes, but can enhance pathological cellular volume changes and cause edema in injury states. Pretreatment with the AQP4 inhibitor TGN-020 significantly reduced the volume of brain edema associated with ischemic injury in a mouse model of focal cerebral ischemia.

Many studies have indicated that a history of depression increases the risk of developing Alzheimer's disease (AD); however, the potential pathogenestic mechanism by which depression functions as a high risk factor for AD remains unknown. Recently, a "cerebral lymphatic system"

The extracellular signal-regulated kinase (ERK) pathway has been reported to play a pivotal role in mediating spinal cord injury (SCI) progression. The present study aimed to investigate the effects of phosphorylated ERK1/2 (p-ERK1/2) inhibition on SCI-induced astrocyte activation and inflammation

In ischemic stroke, vasopressin hypersecretion is a critical factor of cerebral swelling and brain injury. To clarify neural mechanisms underlying ischemic stroke-evoked vasopressin hypersecretion, we observed the effect of unilateral permanent middle cerebral artery occlusion (MCAO) in rats on astrocytic

Acute lung injury (ALI) is a syndrome characterized by damage to the alveolar-capillary wall, pulmonary edema and recruitment of inflammatory cells. Previous studies have indicated that aquaporin 4 (AQP4) plays a key role in brain edema formation and resolution. However
