Abnormal and dysregulated neuroinflammation has been linked to many neurological disorders and neurodegenerative diseases. Understanding the mechanisms of neuroinflammation, their impact on neurodevelopment and how neuroinflammation might be modulated, are currently considered to be critical to improving neurological treatment. ReNcell CX (originating from the cortical region) and VM (originating from the ventral mesencephalon) are human immortalised neural stem cell lines, that have the potential to be used as experimental models for investigating neuroinflammation in vitro. However, the information on the inflammation response of these cells is limited. This is especially more so for undifferentiated ReNcells. In this report we demonstrate using ELISA that cultured, undifferentiated ReNcell CX and VM produce significant amounts of IL-6 in response to IL-1β treatment, but not to LPS treatment. Additionally, conventional RT-PCR showed that ReNcell CX cells expressed TNFR1 and NF-κB, whereas ReNcell VM expressed only NF-κB. Our results encourage further investigation into the relationship between 1L-1β and IL-6 in both ReNcell CX and VM. Moreover, TNF-α treatment might potentially affect neuroinflammation in ReNcell CX, while activation of the NF-κB pathway could also play a critical part in neuroinflammation. |
