Figure Legend Snippet: (A-C) Chemokine secretion in microglia and astrocyte supernatants, 6h after IL-1β challenge (2.5 ng/mL) measured by ELISA for CCL2, CXCL1 and CXCL10. Two way ANOVA, *p<0.001, compared to astrocyte control; #p<0.001, compared to microglia IL-1β. (D) Light microscopy labelling of CCL2 in WT and Tg mice, 2h after i.c. challenge with IL-1β (10 ng) or saline. (E) Confocal imaging of Tg+IL-1β group for CCL2 (red; 594nm) and GFAP (green; 488nm). Iba-1 (green; 488nm) is captured in the inset. (F) Light microscopy labelling of CXCL1. (G) Light microscopy labelling of CXCL10. Insets show detail of positive vascular and astrocytic cells for the different chemokines.
Techniques Used: Enzyme-linked Immunosorbent Assay, Light Microscopy, Imaging
Figure Legend Snippet: Exogenous i.c. administration of LPS in normal mice induces activation of microglial cells to produce regulated secretion of IL-1β and this IL-1β may activate astrocytes to release chemokines such as CCL2, CXCL1 or CXCL10. However, in APP/PS1 mice, LPS stimulates more robust production and processing of IL-1β from microglia primed by Amyloid pathology. Astrocytes primed by amyloid pathology also respond in an exaggerated way to exogenous IL-1β, producing enhanced levels of chemokines. If levels of IL-1, arising endogenously from microglial stimulation, are already exaggerated this will produce a further amplification upon stimulating astrocytes that are hypersensitive to IL-1. These exaggerated responses also appear to affect many other astrocytic transcripts involved in innate immune function as shown by fold-change expression in comparison to WT+saline.
Techniques Used: Activation Assay, Amplification, Expressing
