Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Intravenous Immunoglobulin (IVIg) is widely used as an immunomodulatory therapy. We have recently demonstrated that IVIg protects against airway hyper-reactivity (AHR) and inflammation in mouse models of allergic airway disease (AAD), associated with induction of Foxp3+ regulatory T cells (Treg). Using DEREG (DEpletion of REGulatory T cell) mice, in which endogenous Treg can be ablated with Diphtheria toxin (DTx) treatment, we demonstrate that IVIg generates a de novo population of induced Treg (iTreg) in the absence of endogenous Treg. IVIg-generated iTreg were sufficient for inhibition of ovalbumin-induced AHR in an antigen-driven murine model of AAD. In the absence of endogenous Treg, IVIg failed to confer protection against AHR and airway inflammation. Adoptive transfer of purified IVIg-generated iTreg prior to antigen challenge effectively prevented airway inflammation and AHR in an antigen-specific manner.

- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Changes in Treg function are difficult to quantify due to the lack of Treg-exclusive markers in humans and the complexity of functional experiments. We sorted naive and memory human Tregs and conventional T cells, and identified genes that identify human Tregs regardless of their state of activation. We developed this Treg signature using Affymetrix human genome U133A 2.0 microarrays.

- Affymetrix Clariom S Pico Assay HT (clariomshumanht)
Description
Human CD4+CD45RA+CD25- cells were lentivirally transduced with wild-type or mutated (A384T or R397W) FOXP3, or an empty vector (EV). Transduced cells were sorted 14 days post-transduction based on GFP expression, and were restimulated with soluble anti-CD3 (30 ng/mL) and irradiated PBMCs (3x) for 14 more days. Cells were then activated with 0.5 g/ml of phytohemagglutinin (PHA) in the presence or absence of SGF003 (8 g/mL), and total RNA was extracted for microarray analysis. Overall, this study highlights the functional impact of TIP60 in FOXP3-driven Treg biology and provides a novel target for manipulation of human Treg activity.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Purpose: Unlike in most adult-onset cancers, an association between typical paediatric neoplasms and inflammatory triggers is rare. We studied whether immune system related genes are activated and have prognostic significance in Ewing sarcoma family of tumours (ESFT). Experimental design: Data-analysis was performed on gene expression profiles of 44 ESFT patient, 11 ESFT cell line, and 18 normal muscle tissue samples. 238 inflammation related genes were selected based on literature and a macrophage gene expression signature was derived from SymAtlas. Differential expression of the genes was analysed by t-test and survival analysis was performed according to gene expression.
