MiRNA expression signatures induced by Marek's disease virus infection in chickens.
MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression at the post-transcriptional level. Emerging evidence suggests that differential miRNA expression is associated with viral infection and cancer. Marek's disease virus infection induces lymphoma in chickens. However, the host defense response against Marek's disease (MD) progression remains poorly understood. Here, we uti...
متن کاملDifferential expression of Toll-like receptor pathway genes in chicken embryo fibroblasts from chickens resistant and susceptible to Marek's disease.
The Toll-like receptor (TLR) signaling pathway is one of the innate immune defense mechanisms against pathogens in vertebrates and invertebrates. However, the role of TLR in non-MHC genetic resistance or susceptibility to Marek's disease (MD) in the chicken is yet to be elucidated. Chicken embryo fibroblast (CEF) cells from MD susceptible and resistant lines were infected either with Marek's di...
متن کاملToll-like receptor 3 pathway restricts Marek’s disease virus infection
Marek's disease virus (MDV) is an α-herpesvirus that causes immune suppression and T lymphoma in chickens. Toll-like receptor 3 (TLR3) is critical for the host immune response against MDV infection. Previously, our team demonstrated that pre-treatment of TLR3 agonist poly (I:C) inhibited Marek's disease virus infection in chicken embryo fibroblasts (CEFs). However, whether TLR3 inhibits the agg...
متن کاملDNMT gene expression and methylome in Marek's disease resistant and susceptible chickens prior to and following infection by MDV.
Marek's disease (MD) is characterized as a T cell lymphoma induced by a cell-associated α-herpesvirus, Marek's disease virus type 1 (MDV1). As with many viral infectious diseases, DNA methylation variations were observed in the progression of MD; these variations are thought to play an important role in host-virus interactions. We observed that DNA methyltransferase 3a (DNMT3a) and 3b (DNMT3b) ...
متن کاملEffect of in vitro adaptation of Marek's disease virus on pock induction on the chorioallantoic membrane of embryonated chicken eggs.
Cell-associated preparations of several isolates of Marek's disease virus produced more pocks on the chorioallantoic membrane of embryonated chicken eggs than plaques in duck embryo fibroblasts, thus indicating that lesion response in eggs was more sensitive than cytopathic response in duck embryo fibroblasts for assaying low-passage Marek's disease virus. Adaptation of the virus to cell cultur...
