This study was the first to concurrently identify middle ear pathogens in both bacterial biofilm and intracellularly in the middle ear mucosa of children and to identify extensive DNA stranding in the MEF from children with AOM
To gain further insight into the genetic architecture of psoriasis, we conducted a meta-analysis of 3 genome-wide association studies (GWAS) and 2...
Visceral leishmaniasis (VL) is fatal if untreated, and there are no vaccines for this disease
We identified several novel candidate genes which warrant further analysis in cohorts matched more precisely for clinical phenotypes.

A researcher's work from 20 years ago has helped to crack one of biology’s biggest mysteries.
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.
