Description

Gene expression patterns in house dust mite stimulated CD4 T cells and IgG to IgE ratios - GSE70760

Purpose

Distinguishing benign from pathologic TH2 immunity in atopic children

Hypothesis

HDM generate a distinct transcriptomic signature in CD4 T cells.

Experimental Design

The study design consisted of 45 subjects and two conditions (medium control, HDM stimulation).

Experimental Variables

Stimulation with HDM

Controls

Stimulation with AIM-V medium alone.

Methods

PBMC from house dust mite (HDM) sensitized atopics were cultured in the presence or absence of HDM extract for 24 hours. At the termination of the cultures, CD4 T cells were isolated using immunomagnetic separation. Gene expression was profiled on microarrays.

Additional Information

The microarray data was preprocessed in R employing the RMA algorithm and a custom chip description file (hugene10st_Hs_ENTREZG, v19). ComBat was used to adjust the data for batch effects.

Platform Affymetrix HuGene-1_0-st (hugene10st_Hs_ENT) v1
