Our goal was to identify genetic risk factors for severe otitis media (OM) in Aboriginal Australians.
The interleukin (IL)-6 family of cytokines and exaggerated signal transducer and activator of transcription (STAT)3 signaling is implicated in idiopathic pulmonary fibrosis (IPF) pathogenesis, but the mechanisms regulating STAT3 expression and function are unknown. Suppressor of cytokine signaling (SOCS)1 and SOCS3 block STAT3, and low SOCS1 levels have been reported in IPF fibroblasts and shown to facilitate collagen production. Fibroblasts and lung tissue from IPF patients and controls were used to examine the mechanisms underlying SOCS1 down-regulation in IPF.
Visceral leishmaniasis (VL; Leishmania donovani) cases produce interferon-γ and tumor necrosis factor in response to soluble leishmanial antigen in whole-blood assays. Using transcriptional profiling, we demonstrate the impact of interleukin-10, a cytokine implicated in VL, on this response.
The recent increase in babies born with brain and eye malformations in Brazil is associated with Zika virus (ZIKV) infection in utero. ZIKV alters host DNA methylation in vitro. Using genome-wide DNA methylation profiling we compared 18 babies born with congenital ZIKV microcephaly with 20 controls. We found ZIKV-associated alteration of host methylation patterns, notably at RABGAP1L which is important in brain development, at viral host immunity genes MX1 and ISG15, and in an epigenetic module containing the causal microcephaly gene MCPH1. Our data support the hypothesis that clinical signs of congenital ZIKV are associated with changes in DNA methylation.
To identify genes with putative epigenetic functions, we developed an in silico pipeline to interrogate the T. gondii proteome of 8313 proteins
Overall the analyses do not suggest individual sequence variants account for differences in clinical outcome or adaptation to different hosts.
MMP1 is regulated by factors other than FLI1, and that the influence of IL-6 on MMP1 was independent of its effect on FLI1 in Leishmania braziliensis
Our results imply a role for IgG-mediated inflammation in determining delayed-type hypersensitivity associated with asymptomatic leishmaniasis
Resulting data represents the consequence of transcriptional regulation in each analyzed state of mammalian cells.
These results highlight how UNICORN can enable reliable, powerful, and convenient genetic association analyses without access to the individual-level data
