Description
The complex milieu of inflammatory mediators associated with many diseases is often too dilute to directly measure in the periphery, necessitating development of more sensitive measurements suitable for mechanistic studies, earlier diagnosis, guiding selection of therapy, and monitoring interventions. Previously, we determined that plasma of recent-onset (RO) Type 1 diabetes (T1D) patients induce a proinflammatory transcriptional signature in fresh peripheral blood mononuclear cells (PBMC) relative to that of unrelated healthy controls (HC). Here, using an optimized cryopreserved PBMC-based protocol, we analyzed larger RO T1D and HC cohorts. In addition, we examined T1D progression by looking at longitudinal, pre-onset and longstanding T1D samples.

Description
The precise makeup of chromatin remodeling complexes is important for determining cell type and cell function. The SWI/SNF chromatin remodeling complex is made up of multiple subunits that can be filled by mutually exclusive proteins. Inclusion or exclusion of these proteins has profound functional consequences, yet we currently understand little about the direct functional relationship between these biochemically distinct forms of remodeling complexes. Here we combine chromatin immunoprecipitation, transcriptome analysis, and transcription factor binding information from the ENCODE project to determine the functional relationship between three biochemically distinct forms of SWI/SNF. We find widespread overlap in transcriptional regulation and the genomic binding of the three ARID (AT-Rich Interacting Domain) subunits of SWI/SNF. Despite the numerous similarities in their transcriptional regulation and the co-factors bound with each ARID we identify several novel interaction modalities. Previous work has found examples of competition or subunit switching at individual loci, and we find this functional relationship is widespread, and in these cases gene expression changes following loss of one ARID depend on the function of another ARID. We also identify a previously unknown cooperative interaction between ARID1B and ARID2 in the repression of a large number of genes. Together these data help untangle the complicated combinatorial relationships between a highly heterogenous chromatin remodeling family. Overall design: We performed depletion of ARID subunits (ARID1A , n=5; ARID1B, n=3, ARID2, n=5) of SWI/SNF using siRNA or a Non-Targeting control (N=6) and performed expression analysis using polyA+ selected RNA and a strand-specific dUTP incorporation library protocol.

Description
Vaccination reduces morbidity and mortality from pneumonia but its effect on the tissue-level response to infection is still poorly understood. We evaluated pneumonia disease progression, acute phase response and lung gene expression profiles in mice inoculated intranasally with virulent gram-positive Streptococcus pneumoniae serotype (ST) 3, with and without prior immunization with pneumococcal polysaccharide ST 3 (PPS3), or co-immunization with PPS3 and with a low dose of lipopolysaccharide (LPS). Pneumonia severity was assessed in the acute phase, 5, 12, 24 and 48 h post-inoculation (p.i.) and the resolution phase of 7 days p.i. Primary PPS3 specific antibody production was upregulated and IgM binding to pneumococci increased in PPS3-immunized mice. Immunizations with PPS3 or PPS3 + LPS decreased bacterial recovery the lung and blood at 24 and 48 h and increased survival. Microarray analysis of whole lung RNA revealed significant changes in the acute phase protein serum amyloid A (SAA) between noninfected and infected mice, which were attenuated by immunization. SAA transcripts were higher in the liver and lungs of infected controls, and SAA protein was elevated in serum, but decreased in PPS3-immunized mice. Thus, during a virulent pneumonia infection, prior immunization with PPS3 in an IgM-dependent manner as well as co-immunization with PPS3 + LPS attenuated pneumonia severity and promoted resolution of infection, concomitant with significant regulation of cytokine gene expression in the lungs, and acute phase proteins in the lungs, liver and serum.
