Affymetrix Human Gene 2.1 ST Array (hugene21st)
Description
Prevalence and severity of allergic diseases have increased worldwide. To date, respiratory allergy phenotypes are not fully characterized and, in addition, the mechanisms underlying sublingual immunotherapy (SLIT) are still unknown.
Publication Title

Description
Inflammatory diseases such as Aicardi-Goutieres Syndrome (AGS) and severe systemic lupus erythematosus (SLE) are generally lethal disorders that have been traced to defects in the exonuclease Trex1 (DNAseIII). Mice lacking Trex1 similarly die at an early age through comparable symptoms, including inflammatory myocarditis, through chronic activation of the STING (stimulator of interferon genes) pathway. Here we demonstrate that phagocytes rather than myocytes are predominantly responsible for causing inflammation, an outcome that could be alleviated following adoptive transfer of normal bone marrow into Trex1-/- mice. Trex1-/- macrophages did not exhibit significant augmented ability to produce pro-inflammatory cytokines compared to normal macrophages following exposure to STING-dependent activators, but rather appeared chronically stimulated by genomic DNA. These results shed molecular insight into inflammation and provide concepts for the design of new therapies.

Description
Activation of the STING (Stimulator of Interferon Genes) pathway by microbial or self-DNA, as well as cyclic di nucleotides (CDN), results in the induction of numerous genes that suppress pathogen replication and facilitate adaptive immunity. However, sustained gene transcription is rigidly prevented to avoid lethal STING-dependent pro-inflammatory disease by mechanisms that remain unknown. We demonstrate here that after autophagy-dependent STING delivery of TBK1 (TANK-binding kinase 1) to endosomal/lysosomal compartments and activation of transcription factors IRF3 (interferon regulatory factors 3) and NF-B (nuclear factor kappa beta), that STING is subsequently phosphorylated by serine/threonine UNC-51-like kinase (ULK1/ATG1) and IRF3 function is suppressed. ULK1 activation occurred following disassociation from its repressor adenine monophosphate activated protein kinase (AMPK), and was elicited by CDNS generated by the cGAMP synthase, cGAS. Thus, while CDNs may initially facilitate STING function, they subsequently trigger negative-feedback control of STING activity, thus preventing the persistent transcription of innate immune genes.

Description
That commensal bacteria can influence intestinal inflammation has been observed using other models of chronic colitis. Loss of IL-10, a major immunosuppressive cytokine, induces spontaneous colitis in mice. The incidence of spontaneous polyp formation in IL-10-deficient mice was also completely eliminated in the absence of STING

Description
Multiple Endocrine Neoplasia Tumor Syndrome type 1 (MEN 1) is an autosomal dominant tumor syndrome affecting individuals with a heterozygous germline mutaion of the MEN1 gene. MEN 1 carriers commonly develop parathyroid, anterior pituitary, duodenal and pancreatic endocrine tumors. The phenotype of existing mouse models for the MEN 1 syndrome, with a germline heterozygous (hz) Men1 gene inactivation, show close resemblance to the human MEN 1 syndrome. Menin, the protein encoded for by the MEN1/Men1 gene, lacks homology with known proteins, and evidence of its involvement in different cellular processes is steadily growing. Several interaction partners have been identified, involving different interaction sites on the menin protein. Accumulating evidence suggests a role for menin in transcriptional regulation, cell cycle control, apoptosis, chromatin modification and DNA damage response and repair. Loss of heterozygosity (LOH) of the MEN1 gene precedes tumor formation in the MEN 1 heterozygous pancreas. We set out to determine if there is a change in gene expression early on in the hz islet, as compared with islets in wildtype (wt) littermates, long before the LOH events occur. We performed a global mRNA expression microarray on islets from young, five-week-old, hz Men1 mice and their wt littermates, and we have subsequently corroborated a subset of the findings on the qPCR and protein level.
