Cooperation of Toll-like receptor 2 and 6 for cellular activation by soluble tuberculosis factor and Borrelia burgdorferi outer surface protein A lipoprotein: role of Toll-interacting protein and IL-1 receptor signaling molecules in Toll-like receptor 2 signaling.

|
Toll-like receptor 2 (TLR2) and TLR4 play important roles in innate immune responses to various microbial agents.
|
3 |
11441107
|
We have previously shown that human dermal endothelial cells (HMEC) express TLR4, but very little TLR2, and respond to LPS, but not to Mycobacterium tuberculosis 19-kDa lipoprotein, unless transfected with TLR2.
|
4 |
11441107
|
We further characterized the signaling pathway in response to STF, OspA-L, and PSM in TLR2-transfected HMEC.
|
5 |
11441107
|
The TLR2 signaling pathway for NF-kappaB trans-activation shares the IL-1R signaling molecules.
|
6 |
11441107
|
Dominant negative constructs of TLR2 or TLR6 inhibit the responses of STF and OspA-L as well as PSM in TLR2-transfected HMEC, supporting the concept of functional cooperation between TLR2 and TLR6 for all these TLR2 ligands.
|
7 |
11441107
|
Moreover, we show that Toll-interacting protein (Tollip) coimmunoprecipitates with TLR2 and TLR4 using HEK 293 cells, and overexpression of Tollip inhibits NF-kappaB activation in response to TLR2 and TLR4 signaling.
|
8 |
11441107
|
Collectively, these findings suggest that there is functional interaction between TLR2 and TLR6 in the cellular response to STF and OspA-L in addition to S. epidermidis (PSM) Ags, and that engagement of TLR2 triggers a signaling cascade, which shares the IL-1R signaling molecules, similar to the TLR4-LPS signaling cascade.
|
9 |
11441107
|
Our data also suggest that Tollip may be an important constituent of both the TLR2 and TLR4 signaling pathways.

CD26 mediates dissociation of Tollip and IRAK-1 from caveolin-1 and induces upregulation of CD86 on antigen-presenting cells.
|
29 |
16107720
|
We have previously reported that the addition of recombinant soluble CD26 resulted in enhanced proliferation of human T lymphocytes induced by the recall antigen tetanus toxoid (TT) via upregulation of CD86 on monocytes and that caveolin-1 was a binding protein of CD26, and the CD26-caveolin-1 interaction resulted in caveolin-1 phosphorylation (p-cav-1) as well as TT-mediated T-cell proliferation.
|
30 |
16107720
|
Through proteomic analysis, we identify Tollip (Toll-interacting protein) and IRAK-1 (interleukin-1 receptor-associated serine/threonine kinase 1) as caveolin-1-interacting proteins in monocytes.
|
31 |
16107720
|
We also demonstrate that following stimulation by exogenous CD26, Tollip and IRAK-1 dissociate from caveolin-1, and IRAK-1 is then phosphorylated in the cytosol, leading to the upregulation of CD86 via activation of NF-kappaB.
|
32 |

|
Binding of CD26 to caveolin-1 therefore regulates signaling pathways in antigen-presenting cells to induce antigen-specific T-cell proliferation.

Human TOLLIP regulates TLR2 and TLR4 signaling and its polymorphisms are associated with susceptibility to tuberculosis.
|
44 |
22778396
|
Using short hairpin RNA knockdown of TOLLIP in peripheral blood human monocytes, we found that TOLLIP suppresses TNF and IL-6 production after stimulation with TLR2 and TLR4 ligands.
|

In contrast, secretion of the anti-inflammatory cytokine IL-10 was induced by TOLLIP.

We previously demonstrated that DNA and protein covaccination converted naive T cells to Ag-specific iTregs by inducing CD11c+CD40(low)IL-10+ regulatory dendritic cells (DCregs).
|
53 |
22904311
|
In this paper, we report that the event is initiated by coentry of sequence-matched DNA and protein immunogens into the same DC via caveolae-mediated endocytosis, which leads to inhibition of phosphorylation of caveolin-1 (Cav-1), the main component of caveolae, and upregulation of Tollip.
|
54 |
22904311
|
Silencing either Cav-1 or Tollip blocks the negative signaling, leading to upregulated expression of CD40, downregulated production of IL-10, and loss of iTreg-inducing function.

Here, we have addressed the effect of Tollip and MARCH1 on the regulation of MHC II trafficking and TLR signaling.
|
59 |
24600555
|
Our results show that MARCH1-deficient mice splenocytes are impaired in their capacity to produce pro-inflammatory cytokines in response to poly(I:C) and that TLR3 and MHC II molecules interact in the endocytic pathway.
|
60 |
24600555
|
Knocking down Tollip expression in human CIITA(+) HeLa cells increased expression of HLA-DR but reduced the proportion of MHC II molecules associated with the CLIP peptide.
|
61 |
24600555
|
While overexpression of Tollip did not affect HLA-DR levels, it antagonized the function of co-transfected MARCH1.
|
62 |
24600555
|
We found that Tollip strongly reduced MARCH1 protein levels and that the two molecules appear to compete for binding to MHC II molecules.
|
63 |
24600555
|
Altogether, our results demonstrate that Tollip regulates MHC class II trafficking and that MARCH1 may represent a new Tollip target.

Here, we show porin differentially regulated splenic marginal zone (MZ) and follicular zone (FO) B cell responses in contrast to other classical TLR2-ligands FSL-1 and Pam3CSK4.
|
89 |
26174952
|
The protein up-regulated TLR2 and TLR6 and stimulated the activation and costimulatory molecules on FO B cells skewing the cells toward TLR-dependent type-1 cytokine response.
|
90 |
26174952
|
These cells responded to porin by expressing toll-interacting protein (TOLLIP), the TLR2 and -4 signaling inhibitor along with stimulation of the intracellular pathogen recognition receptor NLR caspase recruitment domain containing protein 5 (NLRC5).

The CD1d(hi) MZ B cells released IL-10 unequivocally demonstrating regulatory B cell feature.

Immunization with porin also resulted in transient IL-10 expression by the CD19(+)CD21(hi) B cells prior to plasma cell formation.
