RESUMO

Goose hemorrhagic polyomavirus (GHPV) is not a naturally occurring infection in geese in China; however, GHPV infection has been identified in Pekin ducks, a domestic duck species. Herein, we investigated the prevalence of GHPV in five domestic duck species (Liancheng white ducks, Putian black ducks, Shan Sheldrake, Shaoxing duck, and Jinyun Sheldrake) in China. We determined that the Jinyun Sheldrake duck species could be infected by GHPV with no clinical signs, whereas no infection was identified in the other four duck species. We sequenced the complete genome of the Jinyun Sheldrake origin GHPV. Genomic data comparison suggested that GHPVs share a conserved genomic structure, regardless of the host (duck or geese) or region (Asia or Europe). Jinyun Sheldrake origin GHPV genomic characterization and epidemiological studies will increase our understanding of potential heterologous reservoirs of GHPV.

RESUMO

Activation of the innate immune system requires recognition of pathogen-associated molecular patterns, such as NOD-like receptors. The NOD-like receptor protein 3 (NLRP3) inflammasome is involved in induction of the pro-inflammatory cytokine, IL-1beta, and subsequent inflammatory responses. NLRP3 inflammasome plays important roles in the inflammatory and innate immune responses associated with autoimmune/inflammatory syndrome. However, analysis of the tissue distribution and expression profiles in BALB/c mice is still incomplete. In this study, we investigated the tissue distribution and expression pattern of NLRP3 in BALB/c mice to further elucidate its function in innate immunity in this commonly used laboratory animal model. NLRP3 mRNA expression levels and tissue distribution of the protein were investigated by real-time quantitative PCR and immunohistochemical analyses, respectively. NLRP3 mRNA expression was higher in the kidney and inguinal lymph nodes than in other tissues. Cytoplasmic expression of NLRP3 was detected in the epithelial reticular cells of the spleen and thymus, lymphocytes in the inguinal lymph nodes, cardiac muscle cells, cerebral cortex neurons, alveolar macrophages, renal tubule cells and liver sinusoidal endothelial cells. The results of this study will assist investigators in interpreting site-specific functions and roles of NLRP3 in inflammatory responses.
