Kinetics of IFNa response

ABSTRACT: We describe finely resolved kinetics of the transcriptional response to IFNa in B cells in vivo. Temporal changes in expression of the most robustly induced ISGs were analyzed across 23 (15min - 15hrs) timepoints. Most ISGs reach peak induction at approximately 2hrs and generally in a synchronus manner. These analses provide insight into the regulatory network structure of IFN responses.

Kinetics of IFNa response

Project description:We describe finely resolved kinetics of the transcriptional response to IFNa in B cells in vivo. Temporal changes in expression of the most robustly induced ISGs were analyzed across 23 (15min - 15hrs) timepoints. Most ISGs reach peak induction at approximately 2hrs and generally in a synchronus manner. These analses provide insight into the regulatory network structure of IFN responses. Male C57BL/6 mice were injected subcutaneously with 10,000U IFNa according to time course profile. Splenic B cells were sorted by FACS directly into TriZol and gene expression profiling was performed on Affymetrix Mouse Gene 1.0 ST Arrays.

IFNa dose response in primary murine B cells

Project description:B cells respond robustly to IFNa. Here we analyze gene expression profiles of primary murine splenic B cells treated with 10 fold serially diluted IFNa in vitro. We explore sensitivity to ISGs to IFNa as they relate to dose. Generally ISGs do not cluster significantly in a dose dependent manner. However there are notable spreads in sensitivity to IFNa. Splenic B cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were cultured with IFNa (0U/ml-10 000U/ml) for 2hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays in triplicate for each concentration of IFNa.

B cell response to IFNa in vitro

Project description:Here we analyzed thetranscriptional response to IFNa in activated B cells in vitro. We found robust induction of ISGs as early as 2hrs. Splenic B cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were activated with LPS(10ug/ml) for 48hrs and thereafter cultured with IFNa (100U/ml) for 2hrs or 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays.

Project description:Here we analyzed the transcriptional response to IFNa in activated CD4+ T cells in vitro. We found robust induction of ISGs as early as 2hrs. Splenic CD4+ T cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were activated with CD3/28 beads for 48hrs and thereafter cultured with IFNa (100U/ml) for 2hrs or 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays.

Effect of JAK blockade on IFNa response in B cells in vitro

Project description:B cells respond robustly to type 1 interferons which signal through JAK1 and TYK2. Here we analyzed the effects of a panel of JAK inhibitors on the IFNa transcriptional response in activated B cells in vitro. Splenic B cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were activated with LPS(10ug/ml) for 48hrs and thereafter cultured with IFNa (100U/ml) in the presence or absence of JAK inhibitors at IC80 for 2hrs or 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays.

Cell specific response to IFNa

Project description:We report cell specific responses to IFNa in 11 different peripheral immunocyte populations in the mouse. These cells represent the core ImmGen immunocyte lineage panel. Profiles from these were used to analyze cell specific responses to IFNa. In general a core set of ISG transcripts are induced in all cells. Smaller sets of ISGs were induced in a cell specific manner. In particular, splenic granulocytes and dendritic cells show restriced indcution of sets of ISGs.
