...(IL)-8 at 1 and 3hpi and interferon (IFN)-α late 24 and 48hpi. Altogether, our results suggest that the concurrent up-regulation of IFNα, IL-1b and IL-6 with higher viral load could represent an important feature affecting the viral pathogenicity and associated with impairment of innate immune response that in turn facilitate and magnify the effect of co-infections....

...ytokines, chemokines and interferons. Through Janus kinase/signal transducers and transcription activators pathway, interferon induces the transcription of interferon-stimulated genes (ISGs), responsible for playing an essential and decisive role in the virus pathology. Some studies have already reported the overexpression of these genes against IBDV infection in susceptible cells. The pro...

Similarly, Thymosin alpha 1 (Tα-1) helps to fight against different infections such as cancer and hepatitis with its immune modulating properties as well as through its direct action on target cells. The recombinant expression of some proteins in E. coli produces inclusion bodies which are misfolded proteins. The objective of t...

In this systematic review and meta-analysis, a review of articles evaluating response rate to Peginterferon alfa-2a was done through the databases of Scopus, Google Scholar, Pubmed (inception - 2019). Fourteen studies reporting the response rate of HBeAg negative chronic patients’ response to Peginterferon alfa-2a were included in the stud...

When cells encounter growth hormones and cytokines, STAT5A is activated to regulate gene transcription. STA5A has an important role in fertilization, embryonic survival and milk production traits in farm animals. The genomic characterization of STAT5A gene has not been assessed before in Nili Ravi Buffalo. In present research work, the seq...

...n reading frame encoding interferon alpha (IFNα) of the camel liver, Camelus dromedarius was isolated and cloned using reverse transcription-PCR. Sequence analysis of that gene showed a 564-bp encoding a protein of 187 amino acids with a predicted molecular weight of 21 kDa. Basic local alignment search tool (BLAST) sequence analysis revealed that C. dromedarius IFNα gene shares high sequence identity with IFNα genes of other sp...

PL motif ESEV was found in 6 isolates from chicken and ducks circulating in such population whereas 17 viruses have ESKV similar to those reported in human in 2006. Based on NS1 sequence analysis of the H5N1 Egyptian viruses, neither geographic nor species signature were reported. This study indicates indep...
