Abstract:

This in vitro study was conducted to evaluate lymphocyte blastogenic and cytokine production by bovine peripheral blood mononuclear cells (PBMCs) stimulated with phytohemagglutinin (PHA), pokeweed mitogen (PWM) and concanavalin A (Con A) mitogens, by using tetrazolium salt and ELISA tests, respectively. The results presented that  Interleukin-2 (IL-2), IL-4, IL-5, IL-10, IL-17 and IFN-γ production in response to PWM mitogens was the highest and Con A the lowest amount and the median values of three mitogens were in the following order: PWM > PHA > Con A > cell control. In the case of IL-6, the production of this cytokine was the same amount for PWM and Con A and a lower amount for PHA stimulation. The results of this study not only showed a normal range for the production of these cytokines from PBMCs that were affected by mitogens, but it demonstrated that the bovine immune system at 2.5 to 3 months was post-natally matured enough to mount an effective immune response to mitogens as well as specific antigens.

Effects of supplemental chromium on production of cytokines by mitogen-stimulated bovine peripheral blood mononuclear cells.

This study determined whether supplementing the diets of dairy cows during the peripartum period with organic trivalent Cr influenced the capacity of their peripheral blood mononuclear cells to produce activation cytokines in response to stimulation with mitogens in vitro. Nine cows were fed 0.5 ppm of Cr/d per cow from 6 wk prepartum to 16 wk postpartum; 10 other periparturient cows served as ...

Inactivated bovine herpesvirus 1 induces apoptotic cell death of mitogen-stimulated bovine peripheral blood mononuclear cells.

Bovine herpesvirus 1 (BHV-1) is able to inhibit the proliferation of bovine peripheral blood mononuclear cells. Here, we have demonstrated that live BHV-1 and, interestingly, inactivated BHV-1 can induce apoptosis of mitogen-stimulated bovine peripheral blood mononuclear cells in vitro.

Changes in some pro-and anti-inflammatory cytokines produced by bovine peripheral blood mononuclear cells following foot and mouth disease vaccination

Interleukin (IL)-17 is exclusively produced by CD4 helper T-cells upon activation. It most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines IL-6, IL-8, TNF-α, and granulocyte-macrophage colony-stimulating factor (GM-CSF). In this study, we studied the in-vitro IL-17 response to specific antigens and a variety of mitogens and compared the IL-1...

Release of cytokines by stimulated peripheral blood mononuclear cells in chronic periodontitis.

OBJECTIVE The emergence of periodontal medicine increased interest in defining the behaviour of peripheral blood cells in periodontitis subjects in comparison with healthy group. The aim of this study was to evaluate the levels of interleukin (IL)-8, tumour necrosis factor-α (TNF-α), IL-6 and IL-10 released by Escherichia coli lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cel...
