Reactive gliosis is a glial response to a wide range of central nervous system
insults, which results in cellular and molecular changes to resting glial cells.
Despite its fundamental effect on neuropathologies, the identification and
characterization of the molecular mechanisms underlying this process remain to be
fully elucidated. The aim of the present study was to analyze the expression
profile and functions of the astrocytic neurotrophic factor, meteorin, in the
progression of reactive gliosis. A mouse model of photothrombotic ischemia, and a
primary astrocyte culture were used in the present study. Reverse transcription
quantitative polymerase chain reaction, western blotting and immunofluorescence
staining were performed to examine the expression levels of meteorin and reactive
gliosis markers. Increased expression levels of meteorin were observed in
reactive astrocytes in a photothrombotic ischemia mouse model, as well as in
cultured astrocytes, which were stimulated by transforming growth factor-?1.
Exogenous treatment of the astrocytes with meteorin did not induce janus
kinase-signal transducer and activator of transcription 3 signaling, however,
silencing the expression of meteorin in the astrocytes resulted in an
upregulation of reactive astrocyte markers, including glial fibrillary acidic
protein and S100?, indicating that endogenous meteorin is required for the
maintenance of astrocytic homeostasis. These results suggested a novel role for
meteorin as a negative feedback effector in reactive gliosis.
