Comparison of the expression of cytokine genes in the bursal tissues of the chickens following challenge with infectious bursal disease viruses of varying virulence [PDF]

, 2010
BACKGROUND: Cytokines are important mediators and regulators of host responses against foreign antigen, with their main function to orchestrate the functional activities of the cells of the immune system.

Differential gene expression in chicken primary B cells infected ex vivo with attenuated and very virulent strains of infectious bursal disease virus (IBDV).

Journal of General Virology, 2017
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), causing immunosuppression and morbidity in young chickens.

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

Molecular epidemiology of infectious bursal disease virus in Zambia [PDF]

, 2013
Nucleotide sequences of the VP2 hypervariable region (VP2-HVR) of 10 infectious bursal disease viruses detected in indigenous and exotic chickens in Zambia from 2004 to 2005 were determined. Phylogenetic analysis showed that the viruses diverged into two

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

The effects of classic and variant infectious bursal disease viruses on lymphocyte populations in specific-pathogen-free White Leghorn chickens [PDF]

, 2003
Infectious bursal disease virus (IBDV) is a pathogen that primarily infects B lymphocytes in domestic avian species. This viral infection has been associated with immunosuppression, clinical disease/mortality, and enteric malabsorption effects.
