Chemoattractants MDC and TARC are secreted by malignant B-cell precursors following CD40 ligation and support the migration of leukemia-specific T cells.
|
2 |
11468146
|
This study demonstrates that the CD40 ligation of these tumor cells also induces the secretion of the CC-chemokines MDC and TARC.
|

|
Supernatants from malignant cells cultured in the presence of sCD40L promote the migration of activated T cells that express CCR4, the common specific receptor for MDC and TARC.
|
4 |
11468146
|
More importantly, the supernatants from CD40-stimulated tumor cells also support the transendothelial migration of autologous CCR4(+) antileukemia T cells.

In contrast, exposure to serum-free medium and interferon-gamma (IFN-gamma) rapidly influences CD83+ DCs to secrete high levels of IL-12, IL-6, and MIP-1beta, and promotes Dcl differentiation.
|
14 |
11642602
|
In contrast, CD83+ DCs matured in serum-free medium in the absence of IFN-gamma, or in the presence of calcium signaling agents, prostaglandin-E2, or IFN-alpha, produce no IL-12, scant IL-6, and prodigious IL-8, MDC, and TARC, and promote Dc2 differentiation.
|
15 |
11927652
|
Stimulation of DC with IFN-gamma increased the release of interleukin (IL)-12 and tumor necrosis factor-alpha and inhibited the production of IL-10.
|
16 |
11927652
|
Moreover, IFN-gamma-treated DC up-regulated the release of CXCL10 (IP-10) markedly and reduced the secretion of CCL17 TARC significantly, attracting preferentially T-helper (Th)1 and Th2 cells, respectively.
|
17 |
11927652
|
Compared with DC pulsed with soluble Tat, DC incubated with RBC-Tat elicited specific CD4+ and CD8+ T-cell responses at a much lower antigen dose.
|
18 |
11927652
|
Finally, immature and mature DC exposed to IFN-gamma were better stimulators of allogeneic T cells and induced a higher IFN-gamma production from Tat-specific CD4+ and CD8+ T lymphocytes.
|
19 |
12218781
|
Mature DC expressed significant amounts of mature DC markers (CD83) and the costimulatory molecules CD80 and CD86.
|
20 |
12218781
|
These clinical grade DC secreted high levels of the chemokines dendritic cell chemokine 1 (DC-CK1), interleukin-8 (IL-8), macrophage-derived chemokine (MDC), and thymus and activation-regulated chemokine (TARC).
|
21 |

|
Upon stimulation by infectious agent products, dendritic cells (DC) become activated, express high levels of class I and class II antigens, CD80, CD86 and CD83 and migrate to secondary lymphoid organs where they can prime naive CD4-helper and CD8-cytotoxic T-cells.
|
22 |
12547595
|
Cognate CD4(+) T-cell help mediated by CD40L along with DC stimulation with another T-cell effector molecule, termed lymphocyte activated gene-3 (LAG-3 or CD223, a ligand for MHC class II) have been shown to induce this maturation process.
|
23 |
12547595
|
Both CD40L and LAG-3 have been used as vaccine adjuvants to induce CTL and CD4 Th1 responses.
|
24 |
12547595
|
LAG-3Ig, unlike CD40L, induced an inflammatory signal in terms of IL-8 and MIP-1alpha/CCL3 production and, in contrast to LPS, induced production of chemokines (MDC/CCL22 and TARC/CCL17) known to direct the migration of maturing DC to lymph nodes.
|
25 |
12547595
|
In LAG-3-matured DC, surface expression of CCR5 (a receptor for MIP-1alpha/CCL3) was down-regulated and CCR7 (a receptor for MIP-3beta and SLC) was up-regulated.
|
26 |
12547595
|
However, LAG-3-matured, but not LPS- or CD40L-matured DC retained their capacity to migrate in chemotaxis chambers and to respond to MIP-1alpha.
|
27 |

|
However, in EBV-positive Hodgkin's disease (HD) the efficacy of adoptively transferred EBV-specific CTL may be limited by tumor-derived immunosuppressive factors, such as T-cell growth factor (TGF) beta, interleukin (IL)13 and the chemokine TARC.
|
28 |
14685154
|
EBV-specific CTL transduced with a retrovirus vector expressing the p40 and p35 subunits of IL12 as a single molecule (Flexi-IL12), produced IL12 following antigenic stimulation.
|
29 |
14685154
|
This resulted in an elevated production of Th1 cytokines, including interferon gamma and tumor necrosis factor alpha, and a reduction in the Th2 cytokines IL4 and IL5.
|
30 |
14685154
|
Flexi-IL12-transduced CTL resisted the antiproliferative and anticytotoxic effects of exogenous TGFbeta, likely by antagonizing the TGFbeta-induced downregulation of the Th1 transcriptional factor T-bet.

Few Ig+ cells expressed CCR2, CCR3, or CCR9, and there was no difference in the expression of these receptors between IgA+ and IgG+ cells.
|
32 |
15996192
|
In contrast, CCR4, CCR5, and CXCR3 was expressed on significantly more IgG+ than IgA+ cells.
|
33 |
15996192
|
IgG+ memory cells migrated to a higher extent than IgA+ cells towards the CXCR3 ligand CXCL11/I-TAC, while there was only a small migration towards the CCR4 ligand CCL17/TARC and the CCR9 ligand CCL25/TECK.
|
34 |
15996192
|
In conclusion, this study shows that IgG+ and IgA+ memory B cells have a differential expression of the Th1 associated chemokine receptor CXCR3, as well as of CCR4 and CCR5.

Maturation of human monocyte-derived dendritic cells (MoDCs) in the presence of prostaglandin E2 optimizes CD4 and CD8 T cell-mediated responses to protein antigens: role of PGE2 in chemokine and cytokine expression by MoDCs.
|
36 |
16303787
|
We demonstrate here that the addition of PGE2 to TNF for the maturation of MoDCs enhanced CD4 and CD8 T cell proliferative responses to neoantigen and recall antigen, and enhanced Th1-type responses.
|
37 |
16303787
|
The increased stimulatory capacity of MoDCs matured with PGE2 was associated with a fully mature, migratory-type MoDC phenotype and more rapid down-regulation of the expression of inflammatory chemokines, with up-regulated expression of the constitutive chemokines TARC and MDC.
|
38 |
16303787
|
In addition, although MoDCs matured with TNF and PGE2 selectively produced the inhibitory IL-12p40 subunit at steady state, they were able to produce the bioactive IL-12p70 heterodimer after stimulation with CD40 ligand and/or IFN-gamma.
|
39 |
16303787
|
Despite increased IL-6 mRNA expression, MoDCs matured with PGE2 did not overcome the suppressive effects of CD4+ CD25+ T cells in allogeneic mixed lymphocyte reactions.

As proof-of-principle we chose to target the interaction of the chemokines CCL22 and CCL17 with their receptor CCR4.
|
44 |
18621704
|
CCR4 was posited as an adjuvant target based on its expression on CD4(+)CD25(+) regulatory T cells (Tregs), which negatively regulate immune responses induced by dendritic cells (DC), whereas CCL17 and CCL22 are chemotactic agents produced by DC, which are crucial in promoting contact between DC and CCR4(+) T cells.
|
45 |
18621704
|
Molecules identified by virtual screening and molecular docking as CCR4 antagonists were able to block CCL22- and CCL17-mediated recruitment of human Tregs and Th2 cells.
|
46 |
18621704
|
Furthermore, CCR4 antagonists enhanced DC-mediated human CD4(+) T cell proliferation in an in vitro immune response model and amplified cellular and humoral immune responses in vivo in experimental models when injected in combination with either Modified Vaccinia Ankara expressing Ag85A from Mycobacterium tuberculosis (MVA85A) or recombinant hepatitis B virus surface antigen (rHBsAg) vaccines.

Here, we show that monocyte-derived immature human DCs stimulated with polyinosinic acid:polycytidylic acid, IFN-alpha, tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and IFN-gamma, alpha-type 1-polarized DC (alpha DC1), secrete profuse amounts of the CXCR3 ligand CXCL9/MIG and substantial amounts of CXCL10/IP-10 and CXCL11/I-TAC after withdrawal of maturation stimuli.
|
56 |
18632652
|
In sharp contrast, no measurable production of these chemokines was found in DCs after maturation with the current gold standard maturation cocktail for human DC-based cancer vaccines consisting of TNF-alpha, IL-1 beta, IL-6, and prostaglandin-E(2) (PGE(2)-DC).
|
57 |
18632652
|
PGE(2)-DCs preferentially produced the Th2 and regulatory T-cell-attracting chemokines CCL17/TARC and CCL22/MDC, whereas only marginal levels of these chemokines were produced by alpha DC1s.
|
58 |
18632652
|
Functional studies in vitro showed that supernatants from mature alpha DC1s actively recruited CD3(-)CD56(+) NK cells and that adding anti-CXCL9/MIG antibodies to the alpha DC1 supernatant substantially reduced this recruitment.
|
59 |
18632652
|
Finally, alpha DC1s were able to induce IFN-gamma production when cocultured with resting autologous NK cells, but only if concurrent CD40 ligation was provided.

Moreover, we demonstrate that RSV-specific memory CD8 T cells, when present in sufficient numbers, inhibit the production of the Th2-associated chemokines CCL17 and CCL22.

19450895
|
Using the recently developed chemokine protein arrays, we analyzed 38 chemokines associated with monocyte-derived DC (MoDC), including the CC family (CCL2, CCL3, CCL4, CCL17, CCL18, CCL22, CCL23, CCL24, CCL27) and the CXC family (CXCL3, CXCL5, CXCL7, CXCL8, CXCL16) chemokines.
|
63 |
19450895
|
Our results indicate that MoDC largely inherit the chemokines constitutively expressed by monocytes, with a significant induction of CCL17, CCL22 and CCL23.
|
64 |
19450895
|
Spent culture supernatant collected from MoDC exhibited chemotatic abilities to activate CD4(+), CD8(+), and CD25(+) Foxp3(+) regulatory T cells (Tregs).
|
65 |
19450895

The serum levels of Th2 markers, including CCL17 (thymus and activation-regulated chemokine [TARC]), CCL22 (macrophage-derived chemokine [MDC]), and soluble CD30, were measured in 101 HIV-negative tuberculosis patients, 103 healthy community controls, and 18 tuberculosis patients in recovery.
|
83 |
21270281
|
The levels of CCL17/TARC (249.8 ± 19.91 versus 143.9 ± 10.54, P < 0.0001) and sCD30 (7.78 ± 0.44 versus 4.93 ± 0.23, P < 0.0001) were significantly higher in patients with active tuberculosis than in controls; however, the CCL22/MDC serum level had no statistical difference between the groups (579.9 ± 16.42 versus 556.5 ± 15.29, P = 0.298).

A CCR4 antagonist combined with vaccines induces antigen-specific CD8+ T cells and tumor immunity against self antigens.
|
87 |
21908423
|
CCR4 antagonists, an emergent class of Treg inhibitor, have been shown to block recruitment of Tregs mediated by CCL22 and CCL17.
|
88 |
21908423
|
Our aim was to demonstrate the ability of a CCR4 antagonist (a small chemical molecule identified in silico) when combined with vaccines to break peripheral tolerance controlled by Tregs, a prerequisite for the induction of CD8(+) T cells against self Ags.
|
89 |
21908423
|
Immunization of transgenic or normal mice expressing tumor-associated self Ags (Her2/neu, OVA, gp100) with a CCR4 antagonist combined with various vaccines led to the induction of effector CD8(+) T cells and partial inhibition of tumor growth expressing self Ags in both prophylactic and therapeutic settings.
|
90 |
21908423
|
The CCR4 antagonist was more efficient than cyclophosphamide to elicit anti-self CD8(+) T cells.
|
91 |
21908423
|
We also showed that the population of Tregs expressing CCR4 corresponded to memory (CD44(high)) and activated (ICOS(+)) Tregs, an important population to be targeted to modulate Treg activity.
|
92 |
21908423
|
CCR4 antagonist represents a competitive class of Treg inhibitor able to induce functional anti-self CD8(+) T cells and tumor growth inhibition when combined with vaccines.

Four out of the twenty-five 9-mer peptides tested: peptides 3 (F33-41), 13 (F214-222), 14 (F273-281), and 23 (F559-567), were found to bind to HLA-A*0201 with moderate to high affinity and were capable of inducing IFN-γ and IL-2 secretion in lymphocytes from HLA-A*0201 transgenic (HLA-Tg) mice pre-immunized with RSV or recombinant adenovirus expressing RSV F.
|
94 |
21980478
|
HLA-Tg mice were immunized with these four peptides and were found to induce both Th1 and CD8+ T cell responses in in vitro secondary recall.

A significant reduction of lung viral load was observed in mice immunized with peptide 23, which appeared to enhance the levels of inflammatory chemokines (CCL17, CCL22, and IL-18) but did not increase eosinophil infiltration in the lungs.
|
96 |
22119586
|
The levels of serum IgE and Th2 chemokines such as eotaxin, TARC, in spleen cells were also reduced by poly(I:C).
|

|
Furthermore, among six predefined populations of myeloid-derived suppressor cells, two were prognostic for overall survival, and among over 300 serum biomarkers, we identified apolipoprotein A-I (APOA1) and chemokine (C-C motif) ligand 17 (CCL17) as being predictive for both immune response to IMA901 and overall survival.

Other genes associated with asthma including FcγRIIb, MMP-14, CCL-8, CCL-17, ADAM-8, LTBR1, aquaporin-9 and IL-7R were also expressed at higher levels in Ova sensitized/challenged animals when compared to BAMs isolated from control animals.
|
99 |

|
Eotaxin 2 (CCL-24), which is known to influence eosinophil migration, was highly up-regulated in BAMs, but not Eotaxin-1 (CCL-11).
