Affymetrix Chicken Genome Array (chicken)
Description
Recombinant chicken IFN1 was prepared as previously reported (Laidlaw et al, 2013) and was added in chicken embryo fibroblasts to a final concentration of 1000 U/ml. Confluent cells were treated with chicken IFNa or mock treated and incubated for six hours before harvesting. The experiment was repeated in triplicate with three different batches of CEFs.

- Affymetrix Chicken Genome Array (chicken)
Description
Infectious bursal disease virus (IBDV) belongs to the family Birnaviridae and is economically important to the poultry industry worldwide. IBDV infects B cells in the bursa of Fabricius (BF), which can cause severe immunosuppression and mortality in young chickens. Earlier studies have shown that strains of IBDV lose their virulence potential after serial passage in non-B lymphoid cells, for reasons that are poorly understood. This study aimed to investigate the gene expression profiles of one cell-culture adapted attenuated IBDV strain (D78) and one very virulent IBDV strain (UK661) in chicken primary B cells cultured ex vivo from the bursa of Fabricius. The viruses were studied in B cells over 48h and their gene expression was initially evaluated with qPCR. The mRNA was isolated from the cells at 18 hours post-infection and screened with Affymetrix microarrays in triplicate. The study included mock controls which were conducted in triplicate.

Description
Transcriptional profiles are increasingly used to investigate the severity, subtype and pathogenesis of disease. We now describe whole blood RNA signatures and local and systemic immune mediator levels in a large cohort of adults hospitalised with influenza from which extensive clinical and investigational data was obtained. Signatures reflecting interferon-related antiviral pathways were common up to day 4 of symptoms in cases not requiring mechanical ventilatory support; in those needing mechanical ventilation, an inflammatory, activated neutrophil and cell stress/death (bacterial) pattern was seen, even early after disease onset. Identifiable bacterial co-infection was not necessary for this bacterial signature but could enhance its development while attenuating the early viral signature. Our findings emphasise the importance of timing and severity in the interpretation of transcriptomic profiles and soluble mediator levels, and identify specific patterns of immune activation that may enable the development of novel diagnostics and therapeutics

The study aimed to define transcriptional signatures for detection of active TB (TB) compared to latent TB infection (LTBI) as well as to other diseases (OD) with similar clinical phenotypes in patients with and without HIV in two African paediatric populations.
