1. INTRODUCTIONAvian nephritis virus (ANV) is an etiological agent of growth retardation of young chickens by causing interstitial nephritis (Imada et al., 1979). Antibodies against ANV have been found in chicken and turkey flocks in the UK and Japan, suggesting a broad distribution (Nicholas et al., 1988; Takase et al., 2000).It is originally considered to be a picornavirus, was later characteriz ...

 1. IntroductionTLRs and their downstream signaling components are mostly conserved in chickens (Lillehoj and Li, 2004; Lynnet al., 2003; Philbin et al., 2005), except for TLR4 (Keestraand van Putten, 2008). In mammals, TLR4 is expressed in a variety of immune and non-immune cells (Arpaia et al.,2011; Tang et al., 2008). One of the well-characterized ligands that binds with TLR4 is LPS derive ...
