Uptake of microparticle-adsorbed protein antigen by bone marrow-derived dendritic cells results in up-regulation of interleukin-1 alpha and interleukin-12 p40/p35 and triggers prolonged, efficient antigen presentation.

|
This is evidenced by the de novo synthesis of transcripts of interleukin-1 alpha and interleukin-12 p40/p35 as well as transcripts of MHC class II.

Interferon-gamma receptor ligand-binding chain (IFN-gammaR1) or signaling chain (IFN-gammaR2) deficiency, like interleukin 12 receptor beta1 chain (IL-12Rbeta1) deficiency, predispose to severe infections due to poorly virulent mycobacteria and salmonella.

Mutations in the genes for IFN-gammaR1, IFN-gammaR2, IL-12Rbeta1, and other molecules implicated in IL-12- or IFN-gamma-mediated immunity were sought.

Vasoactive intestinal peptide and pituitary adenylate cyclase-activating polypeptide inhibit interleukin-12 transcription by regulating nuclear factor kappaB and Ets activation.
|
10 |
10542221
|
The vasoactive intestinal peptide (VIP) and the structurally related neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) act as "macrophage-deactivating factors".
|
11 |
10542221
|
We showed previously that VIP and PACAP inhibit the production of macrophage-derived tumor necrosis factor-alpha, interleukin (IL)-6, nitric oxide, and IL-12.
|

|
This study examines the molecular mechanisms involved in the VIP/PACAP inhibition of IL-12 production.
|
13 |
10542221
|
VIP and PACAP inhibit IL-12 (p40) gene expression by affecting both NF-kappaB binding and the composition of the Ets-2 binding complex.
|
14 |
10542221
|
Both neuropeptides prevent the activation-induced nuclear translocation of the NF-kappaB components p65 and c-Rel by inhibiting the reduction in cytoplasmic IkappaBalpha.

Single-chain porcine interleukin-12 was bioactive in vitro on both human and porcine cells as measured by its ability to induce proliferation of lymphoblasts and interferon-gamma secretion by lymph node cells.
|
16 |
10607307
|
In contrast, the p40 subunit of porcine interleukin-12 alone did not induce proliferation or inhibit the activity of the single-chain porcine interkeukin-12.
|
17 |
10607307
|
These results indicate that binding of interleukin-12 to its receptor and transduction of intracellular signals requires both p40 and p35 subunits.

Recently, recessive mutations in the interferon gamma receptor ligand-binding chain (IFN gamma R1), interferon gamma receptor signalling chain (IFN gamma R2), interleukin 12 p40 subunit (IL-12 p40), and interleukin 12 receptor beta 1 chain (IL-12R beta 1) genes have been identified in a number of patients with disseminated BCG or NTM infection.

Similar to EBA-175, the binding of EBP2/BAEBL to human erythrocytes was dependent on sialic acids because neuraminidase treatment of those erythrocytes rendered them incapable of binding, but differed from EBA-175 in that trypsin treatment decreased EBP2/BAEBL binding by only twofold compared to a 10-fold reduction in EBA-175 binding.

Lactoferrin was initially shown to augment IL-12(p40) production from macrophages stimulated with LPS.
|
26 |
15683854
|
A single immunization of mice with Lactoferrin as an adjunct adjuvant resulted in amplified splenocyte proliferative response to heat-killed BCG, and elevated IL-12(p40) production with increased relative ratios of IL-12/IL-10.
|
27 |
15683854
|
Furthermore, splenocyte recall response to HK-BCG was augmented for proinflammatory mediators, TNF-alpha, IL-1beta, and IL-6, approaching responses generated to complete Freund's adjuvant (CFA) immunized controls.

Nonreplicating recombinant vaccinia virus expressing CD40 ligand enhances APC capacity to stimulate specific CD4+ and CD8+ T cell responses.
|
32 |
15812230
|
Recently, we and others have demonstrated, in vitro and in vivo, that coexpression of CD80 and CD86 costimulatory molecules enhances the immunogenic capacity of a recombinant vaccinia virus (rVV) encoding different tumor-associated antigens.
|
33 |
15812230
|
To further investigate the capacity of these vectors to provide ligands for different costimulatory pathways relevant in the generation of T cell responses, we constructed a recombinant virus (rVV) expressing CD40 ligand or CD154 (CD154rVV).
|
34 |
15812230
|
Upon binding the CD40 receptor expressed on antigen presenting cells (APC), this molecule, physiologically expressed on activated CD4+ T cells, increases their antigen presentation and immunostimulatory capacities.
|

|
CD154rVV infection of autologous fibroblasts, monocytes, or iDC promoted the expression of a number of cytokines, including GM-CSF, TNF-alpha, and IL-15 in iDC.
|
36 |
15812230
|
Most importantly, IL-12 p40 gene expression and protein secretion were induced by CD154rVV but not by wild-type VV (WT VV) in either CD14+ cells or iDC, and these effects could be blocked by anti-CD40 monoclonal antibodies.
|
37 |
15812230
|
Furthermore, phenotypic characterization of CD154rVV infected iDC revealed enhanced expression of CD83 and CD86 surface markers as compared with wild-type vaccinia virus infection.
|
38 |
15812230
|
However, cytokine genes typically expressed by T cell receptor triggered T cells such as those encoding IL-2 and IFN-gamma, or T cell proliferation, were detectable to a significantly higher extent in CD154rVV infected cultures, as compared with WT VV.

Activation of specific CD8+ T cells was then investigated using MART-1/Melan-A(27-35) epitope as the model of tumor-associated antigen (TAA).

Chlorophyllin attenuates IFN-gamma expression in lipopolysaccharide-stimulated murine splenic mononuclear cells via suppressing IL-12 production.
|

|
RT-PCR analysis showed that LPS-activated IFN-gamma expression gradually declined by CHL treatment in a dose dependent manner while mRNA production of TNF-alpha, IL-2, and FasL was not changed.
|
42 |
16275627
|
CHL also suppressed IL-12 production (p70, a heterodimer of p40 and p35) and the mRNA expression of IL-12 p40 and IL-12 receptors (both IL-12Rbeta1 and IL-12Rbeta2), which are involved in the induction of IFN-gamma expression.
|
43 |
16275627
|
Furthermore, an electrophoretic mobility shift assay showed that CHL inhibited DNA binding activity of NF-kappaB, STAT-3, and STAT-4 to their cognate DNA recognition motifs, all of which contribute to the IL-12-induced IFN-gamma transcription.
|
44 |
16275627
|
Exogenous addition of recombinant IL-12 abrogated the inhibitory effect of CHL on IFN-gamma and its mRNA expression in LPS-activated splenocytes.
|
45 |
16275627
|
Collectively, these results show that CHL inhibits IFN-gamma production by LPS-stimulated splenic mononuclear cells due to down-regulation of IL-12 production.

Western blot analysis, using monoclonal antibodies, demonstrated that the crucial inter-subunit disulfide bond linking the p35 and p40 subunits is intact in the purified hIL-12.

DC treatment with EV71 VLPs enhanced the expression of CD80, CD86, CD83, CD40, CD54, and HLA-DR on the cell surface; increased the production of interleukin (IL)-12 p40, IL-12 p70, and IL-10 by DCs; and suppressed the capacity of DCs for endocytosis.

|
Neutralization with antibodies against Toll-like receptor (TLR) 4 suppressed the capacity of EV71 VLPs to induce the production of IL-12 p40, IL-12 p70, and IL-10 by DCs and inhibited EV71 VLPs binding to DCs.
