Description
Because of the extensive data in mice supporting the concept that ST2+ Tregs might have desirable therapeutic properties, including tissue repair function, high suppressive capacity, and enhanced stability, we engineered human blood Tregs to constitutively express ST2 (IL-33R). Here we used RNA sequencing to explore the effects of short-term culture with IL-33 on human ST2-transduced Tregs. Overall design: Human naive Tregs flow-sorted from 4 independent donors were lentivirally transduced with ST2, expanded for 13 days, then stimulated with IL-2 and TCR (16 h) or IL-2, TCR, and IL-33 (16 h).

Description
The human nuclear poly(A)-binding protein PABPN1 has been implicated in the decay of nuclear noncoding RNAs (ncRNAs). In addition, PABPN1 stimulates hyperadenylation by poly(A) polymerase, and this activity is thought to be required for decay. Here, we inactivated hyperadenylation by two distinct mechanisms and examined changes in gene expression in HEK293 cells by RNAseq. We observed the upregulation of various ncRNAs, including snoRNA host genes, primary miRNA transcripts, and upstream antisense RNAs, confirming that hyperadenylation is broadly required for the degradation of PABPN1-targets. In addition, we found that mRNAs with retained introns are susceptible to PABPN1 and PAPa/?-mediated decay (PPD). Transcripts are targeted for degradation due to inefficient export, which is a consequence of reduced intron number or incomplete splicing. We conclude that PPD is an important mammalian nuclear RNA decay pathway for the removal of poorly spliced and nuclear-retained transcripts. Overall design: Poly(A)+ RNA from HEK293 cells was analyzed by next generation sequencing following depletion of PAPa and PAP? or expression of a dominant negative allele of PABPN1 (LALA) designed to inhibit polyadenylation. For each condition, we collected both total RNA and a nuclear-enriched sample. Each sample was collected in duplicate.

Description
Rationale: Lipopolysaccharide (LPS) is ubiquitous in the environment. Inhalation of LPS has been implicated in the pathogenesis and/or severity of several lung diseases, including pneumonia, chronic obstructive pulmonary disease and asthma. Alveolar macrophages are the main resident leukocytes exposed to inhaled antigens. Objectives: To obtain insight into which innate immune pathways become activated within human alveolar macrophages upon exposure to LPS in vivo.

Description
Primary human cytomegalovirus (HCMV) infection usually goes unnoticed, causing mild or no symptoms in immunocompetent individuals. Some rare severe clinical cases have however been reported without investigation of host immune responses or viral virulence. In this present study, we investigate, for the first time, phenotypic and functional features together with gene expression profiles in immunocompetent adults experiencing a severe primary HCMV infection. Twenty PHIP were enrolled as well as 26 HCMV-seronegative and 39 HCMV-seropositive healthy controls. PHIP had a huge lymphocytosis marked by massive expansion of NK and T cell compartments. Interestingly, PHIP mounted efficient innate and adaptive immune responses with a deep HCMV imprint, revealed mainly by the expansion of NKG2C+ NK cells, CD16+ V2- T cells and conventional HCMV-specific CD8+ T cells. The main effector lymphocytes were activated and displayed an early immune phenotype that developed toward a more mature differentiated status. We suggest that both huge lymphocytosis and excessive lymphocyte activation could contribute to a massive cytokine production known to mediate tissue damage observed in PHIP. Taken together, these findings bring new insights into the comprehensive understanding of immune mechanisms involved during primary HCMV-infection in immunocompetent individuals.

Description
Mass populations of thyrocytes stably expressing wild type RET/PTC1 oncogene or RET/PTC1 carrying Y451F mutation and parental thyrocytes were used for hybridization on Affymetrix HG-U133A and HG-U133B chips. For each cell condition were generated two different targets (indicated as two different samples in the database, i.e. "Parental Thyrocytes" and "Parental Thyrocytes bis")for a total number of six samples. For the data analysis the two samples from the same condition (i.e. Parental thyrocytes) were considered as duplicates.
