B19 parvovirus (PV) infection is ordinarily resolved with the production of specific antibodies that neutralize virus infectivity for erythroid host cells. Nevertheless persistent infection with B19 PV and pure red blood cell aplasia have been documented. A 27 year-old male. i.v. drug abuser, HIV+ and HCV was diagnosed of pure red cell aplasia. Six months later we had serologic evidence of pers...
Hepatitis C virus (HCV) infection varies in the outcomes depending on both viral and host factors. This study aims to investigate the association of single-nucleotide polymorphisms (SNPs) of IFNAR2, IL10RB, and IL28RA genes with susceptibility to HCV infection and resolution. Genotyping of IFNAR2, IL10RB, and IL28RA gene polymorphisms were performed using TaqMan® method from 552 patients with s...
The pathogenesis of persistent infection is dictated by the balance between opposing immune activation and suppression signals. Herein, virulent Salmonella was used to explore the role and potential importance of Foxp3-expressing regulatory T cells in dictating the natural progression of persistent bacterial infection. Two distinct phases of persistent Salmonella infection are identified. In th...
ویروس bvd یک rna ویروس تک رشته ای است که متعلق به جنس پستی ویروس و خانواده فلاوی ویریده می باشد. این ویروس یکی از معمول ترین پاتوژن های گاوان است که منجر به خسارات اقتصادی فراوانی از جمله کاهش تولید شیر، افت کارایی تولیدمثلی، سرکوب سیستم ایمنی و ناقص الخلقه زایی می شود. همچنین ویروس bvd باعث تولد گوساله های دارای عفونت پایدار یا persistent infection (pi) در گله می گردد. این ویروس در قسمت های مخ...
Acute Epstein-Barr virus (EBV) infection is the most common cause of Infectious Mononucleosis. Nearly all adult humans harbor life-long, persistent EBV infection which can lead to development of cancers including Hodgkin Lymphoma, Burkitt Lymphoma, nasopharyngeal carcinoma, gastric carcinoma, and lymphomas in immunosuppressed patients. BARF1 is an EBV replication-associated, secreted protein th...
