Absence of TNFR1 Promotes a Protective Response in the Early Phase of Hepatic Encephalopathy Induced by Thioacetamide in Mice
Neuroscience letters(2024)
摘要
Hepatic encephalopathy (HE) is a neuropsychiatric syndrome with a wide spectrum of cognitive deficits, motor impairment, and psychiatric disturbances resulting from liver damage. The cytokine TNF has been considered the main cytokine in the development and progression of HE, with a pivotal role in the initiation and amplification of the inflammatory cascade. The aim of the present study was to evaluate the involvement of TNF type 1 receptor (TNFR1) in locomotor deficits and in the levels of TNF, IFN-γ, IL-6, IL-10, IL-12p70, CCL2, CX3CL1 and BDNF from the frontal cortex and hippocampus of TNFR1 knockout mice (TNFR1-/-) mice with HE induced by thioacetamide. Wild-type (WT) animals with HE developed locomotor deficit. The absence of TNFR1 absence of TNFR1 in HE animals attenuated the locomotor activity impairment in parallel with a balanced neuroinflammatory environment 24 h after the administration of thioacetamide. Taken together, the data suggests that the absence of TNFR1 promoted a protective response in the early phase of hepatic encephalopathy induced by thioacetamide in mice.
