Toll-Like Receptor-1 and Receptor-2 and Beta-Defensin in Postcholecystectomy Bile Duct Injury
Postcholecystectomy bile duct injuries (BDI) produce hepatic cholestasis and cause infection of the biliary tract. The biliary cells participate in secreting cytokines and in expression of immune response receptors. Toll-like receptors (TLRs) conduct signalling and activate the innate and adaptive inflammatory response. The objective was to determine the serum levels of TLR-2 and the expression...
متن کاملOccurrence, characteristics and control of pigeon paramyxovirus type 1 in pigeons.
Newcastle disease (ND) is a highly contagious and devastating viral disease of poultry and other birds that has a worldwide distribution. ND in pigeons is called paramyxovirosis and is caused by antigenic "pigeon variant" of the virus (pigeon paramyxovirus type 1, PPMV-1). During PPMV-1 infections, central nervous system symptoms and sometimes high mortality are observed. In the case of infecti...
متن کاملCharacterization of Pigeon Paramyxovirus Type 1 Viruses (PPMV-1) Isolated from Iran
Newcastle disease (ND) is one of the contagious viral diseases in avian species. Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported in limited numbers from Iran and phylogenetic studies have been conducted on partial sequence of NDV fusion (F) gene. In the present study, ten PPMV-1, named Pigeon_paramyxovirus1_isolate_pigeon/Iran/UT_EG...
متن کاملIsolation of an atypical pigeon paramyxovirus type 1 in Poland.
In this study, a pigeon paramyxovirus type 1 (PPMV-1) isolated from a flock of ornamental pigeons in Poland in 2010 is described. The PPMV-1/Poland/H2/10 isolate showed the amino acid sequence at the cleavage site of F2/F1 112KRQKRF117 i.e. typical of virulent strains. Despite having the monoclonal antibody binding pattern typical of pigeon variants PPMV-1 (antigenic group "P"), the Polish isol...
متن کاملClinical Value of Toll Like Receptor 4 and CD14 in Children with Acute Lower Respiratory Tract Infection
Toll like receptors (TLRs) with a myeloid differentiation antigen (CD14) recognize and bind various structures from invading microbes and then trigger cell activation. They initiate a variety of effectors' functions, including cytokine secretion, proliferation, co-stimulation or phagocyte maturation. The aim of this study was to evaluate Toll-like receptor 4 (TLR4) and CD14 expression in childr...
