Detection of gene expression and sequence analysis of chicken class II trans activator (CIITA)
BACKGROUND:Class II transactivator (CIITA) is a dominanttranscriptional element, controlling numerous genes in theimmune system. CIITA is expressed in a constitutive pattern inantigen presenting cells although its expression can occur inother cell types. Since the revelation of CIITA, there have beenconsiderable advances toward understanding its role as anactivator of MHC II genes in humans and...
متن کاملSequence Analysis of HSP70 Gene of Leishmania major and Leishmania tropica in Chabahar and Mashhad
ABSTRACT Background and Objective: Cutaneous leishmaniasis is a parasitic disease and a health problem in different parts of Iran, especially two cities of Mashhad and Chabahar. Due to morphological similarities of most Leishmania species and difference in reservoirs of L. major and L. tropica, it is necessary to determine the parasite speci...
متن کاملNeuraminidase gene sequence analysis of avian influenza H9N2 viruses isolated from Iran
Influenza A viruses possesses two virion surface glycoproteins including haemagglutinin (HA) and neuraminidase (NA). The NA plays an important role in viral replication and promotes virus release from infected cells and facilitates virus spread throughout the body. To find out any genomic changes that might be occurred on NA gene of avian influenza circulating viruses, we have genetically analy...
متن کاملNucleotide Sequence Analysis of S1 Gene among Iranian Avian Infectious Bronchitis Viruses Isolated during 2001-2002
Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...
متن کاملPathogenicity and haemagglutinin gene sequence analysis of Iranian avian influenza H9N2 viruses isolated during (1998–2001)
Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...
