Immunomodulatory Effects of Inactivated Parapoxvirus Ovis (Orf Virus) on Human Peripheral Immune Cells: Induction of Cytokine Secretion in Monocytes and Th1-Like Cells

Cytokine Secretion in Monocytes and Peripheral Immune Cells: Induction of Parapoxvirus Ovis (Orf Virus) on Human Immunomodulatory Effects of Inactivated

Inactivated parapoxvirus ovis (Orf virus) has antiviral activity against hepatitis B virus and herpes simplex virus.

It is known that some viruses are able to induce vigorous immune reactions. This study shows that inactivated parapoxvirus ovis (Orf virus), strain D1701 (PPVO), induces an autoregulatory cytokine response that involves the upregulation of IL-12, IL-18, IFN-gamma and other T helper 1-type cytokines and their subsequent downregulation, which is accompanied by induction of IL-4. An increase in IL...

Effects of inactive parapoxvirus ovis on cytokine levels in rats

The aim of this study is to determine the effects of iPPOV on pro-inflammatory and anti-inflammatory cytokine levels in rats. iPPOV (1 ml/rat) was administered intraperitoneal route to 49 rats, except for 7 rats (Control, 0 group). Serum samples were collected from 7 rats at 1st, 2nd, 4th, 8th, 12th, 16th and 24th hr after treatments. Levels of TNF-α, IL-6, IL-12 and IL-10 were determined using...

Expression of Th1 and Th2 Cytokine and Associated Transcription Factors in Peripheral Blood Mononuclear Cells and Correlation with Disease Severity

Background: Psoriasis is a T cell-mediated autoimmune disease with elevated level of pro-inflammatory cytokines belonging mainly to Th1 pathway. We investigated whether treatment with micronutrients along with methotrexate (MTX) is able to modulate mRNA expression of Th1 and Th2 patterns and its correlation with disease severity. Methods: Thirty plaque type psoriasis patients with Psoriasis ...

The effect of different pulp-capping materials on proliferation, migration and cytokine secretion of human dental pulp stem cells

Objective(s): Biocompatibility of dental biomaterials plays a critical role in regeneration of dental stem cells. The aim of present study was to evaluate the effects of novel biomaterials of TheraCal-LC (TheraCal; Bisco), Angelus mineral trioxide aggregate (MTA; Angelus), calcium-enriched mixture (CEM; BioniqueDent), and Biodentine (Septodont) on viability of human de...
