Affymetrix Human Genome U133A Array (hgu133a)
Description
Th1 and Th2 cells arise from a common precursor cell in response to triggering through the TCR and cytokine receptors for IL-12 or IL-4. This leads to activation of complex signaling pathways, which are not known in detail. Disturbances in the balance between type 1 and type 2 responses can lead to certain immune-mediated diseases. Thus, it is important to understand how Th1 and Th2 cells are generated. To clarify the mechanisms as to how IL-12 and IL-4 induce Th1 and Th2 differentiation and how TGF-beta can inhibit this process, we have used oligonucleotide arrays to examine the early polarization of Th1 and Th2 cells in the presence and absence of TGF-beta after 0, 2, 6 and 48 hours of polarization.

Description
The aim of the dataset was to study on a genome-wide level the effect of GTPase of the human immune associated protein 4 (GIMAP4) knockdown on the gene expression of resting T cells and immediately after T cell activation and Th1(Act+IL12) polarizing conditions of human cord blood-derived CD4+ T cells.
Publication Title
Tubulin- and actin-associating GIMAP4 is required for IFN-γ secretion during Th cell differentiation.

Description
Immunotherapy provides an alternative approach for cancer treatment. However, in-depth analyses of the effects of immunotherapy on the tumor microenvironment (TME) have not been conducted in non-melanoma tumors. Here we describe changes in the pancreatic ductal adenocarcinoma (PDAC) TME following immunotherapy treatment, and show for the first time that vaccine-based immunotherapy directly alters the TME, inducing neogenesis of tertiary lymphoid structures that convert immunologically quiescent tumors into immunologically active tumors. Alterations in five pathways important for immune modulation and lymphoid structure development (TH17/Treg, NFkB, Ubiquitin-proteasome, Chemokines/chemokine receptors, and Integrins/adhesion molecules) in vaccine-induced intratumoral lymphoid aggregates were associated with improved post-vaccination responses. Additional studies in other cancers and patients treated with other forms of immunotherapy are warranted to further develop signatures defined in intratumoral lymphoid structures into biomarkers that predict effective anti-tumor immune responses. These signatures may also expose therapeutic targets for promoting more robust antitumor immune responses in the TME.

Description
Special AT-rich binding protein 1 (SATB1) is a global chromatin organizer and a transcription factor induced by interleukin-4 (IL-4) during the early T helper 2 (Th2) cell differentiation. In this study, we investigated the role of SATB1 in T helper cell differentiation by performing gene expression profiling of human differentiating Th cells in which expression of SATB1 was downregulated by RNA interference (RNAi). Our results indicate that SATB1 is involved in the regulation of more than three hundred genes in primary human CD4+ T cells, including several IL-12 and/or IL-4 regulated factors, suggesting a role in the development or function of Th subtypes.
Publication Title
SATB1 dictates expression of multiple genes including IL-5 involved in human T helper cell differentiation.

Description
The aim of the dataset was to identify genome-wide regulators of gene expression in early differentiation of human cord blood derived CD4+ T cells cultured under Th1 (Act+IL12) and Th2 (Act+IL4) polarizing conditions. Overall design: Total RNA from naive CD4+ T cells was compared to total RNA from cells cultured in the following three conditions: activating (antiCD3+antiCD28)+antiIL4+antiIFNG; activating (antiCD3+antiCD28)+IL12+antiIL4; activating (antiCD3+antiCD28) +IL4+antiIFNG. Samples from 3 biological replicates were analysed.
