TLDR
The data suggest that CCL19 acts as a chicken PWBC chemotactic factor and facilitate the infiltration of PWBC (especially T cells) into the bursae after IBDV infection.

Macrophage Migration Inhibitory Factor Triggers Inflammatory Responses During Very Virulent Infectious Bursal Disease Virus Infection.

TL;DR: High-throughput proteomic sequencing showed that chicken macrophage migration inhibitory factor (chMIF) was upregulated uniquely in primary bursal cells infected with vvIBDV compared with infection by nonpathogenic attenuated IBDV, and elucidates critical molecular determinants underlying vv IBDV-mediated initiation of acute inflammation.

Differential Response of the Chicken Trachea to Chronic Infection with Virulent Mycoplasma gallisepticum Strain Ap3AS and Vaxsafe MG (Strain ts-304): a Transcriptional Profile.

TL;DR: Vaxsafe MG (strain ts-304) is a new vaccine candidate that is efficacious at a lower dose than the current commercial vaccine strain ts-11, from which it is derived and appears to protect the structural and functional integrity of the tracheal mucosa 2 weeks after infection with M. gallisepticum.
Journal ArticleDOI

Effects of infectious bursal disease virus infection on interferon and antiviral gene expression in layer chicken bursa.

TL;DR: Data showed that after the chickens were infected with IBDV, the virus load in the bursa of the Fabricius peaked at 96 h and gradually decreased, and the ZAP change rule was significantly positively correlated with the change rule of the I BDV load.
Journal ArticleDOI

Transcriptome analysis of chicken intraepithelial lymphocyte natural killer cells infected with very virulent infectious bursal disease virus.

TL;DR: This is the first study to examine the whole transcriptome profile of chicken NK cells towards IBDV infection and provides better insight into the early immune response ofChicken NK cells.

Bacillus amyloliquefaciens TL Downregulates the Ileal Expression of Genes Involved in Immune Responses in Broiler Chickens to Improve Growth Performance

TL;DR: In this article, RNA-sequencing (RNA-seq)-based transcriptomes of ileal tissues collected from probiotic-fed and control broiler chickens were analyzed to elucidate the effects of the probiotic B. amyloliquefaciens TL, as a feed additive, on the gut immune function.

CCR7 and its ligands: balancing immunity and tolerance

TL;DR: This work focuses on the cellular and molecular mechanisms that enable CCR7 and its two ligands, CCL19 and CCL21, to balance immunity and tolerance.
Journal ArticleDOI

Chemokines and leukocyte traffic.

TL;DR: Twenty years after the discovery of chemokines is an appropriate time to review leukocyte traffic and to assess the knowledge and opportunities that have arisen from countless studies of the large and tight-knit family of chemotactic proteins.
Journal ArticleDOI

Chemokines define distinct microenvironments in the developing thymus.

TL;DR: Developing thymocytes respond to chemokines expressed in distinct microenvironments within the thymic stroma in a way that correlates well with the previously observed migration pattern from cortex to medulla.

CCR7 ligands CCL19 and CCL21 increase permissiveness of resting memory CD4+ T cells to HIV-1 infection: a novel model of HIV-1 latency.

TL;DR: A unique action of the chemokines CCL19 and CCL21 is demonstrated and a novel model with which to study HIV-1 latency in vitro is provided and is demonstrated to facilitate efficient entry of HIV- 1 into resting CD4(+) T cells.
Journal ArticleDOI

Infectious bursal disease virus: strains that differ in virulence differentially modulate the innate immune response to infection in the chicken bursa.

TL;DR: F52/70 seems to use a "stealth" approach by not inducing the type I IFNs, whereas UK661 down-regulates their expression, which suggests that both viruses modulate the host immune response, although probably by using different mechanisms.
