U83A efficiently and potently induced calcium mobilization in cells expressing single human CCR1, CCR4, CCR6, or CCR8, with EC50 values <10 nM.
|
2 |
16365449
|
U83A also induced chemotaxis of Th2-like leukemic cells expressing CCR4 and CCR8.
|
3 |
16365449
|
High-affinity binding, 0.4 nM, was demonstrated to CCR1 and CCR5 on monocytic/macrophage cells, and pretreatment with U83A or modified forms could block responses for endogenous ligands.
|

16365449
|
U83A-Npep acted only as antagonist, efficiently blocking binding of CCL3 to CCR1 or CCR5 on differentiated monocytic/macrophage leukemic cells.
|
5 |
16365449
|
Furthermore, CCL3 induction of calcium signaling via CCR1 and CCL1 induced chemotaxis via CCR8 in primary human leukocytes was inhibited.
|

16365449
|
However, late in infection, when full-length U83A is made, chemoattraction of CCR1-, CCR4-, CCR5-, CCR6-, and CCR8-bearing monocytic/macrophage, dendritic, and T lymphocyte cells can facilitate dissemination via lytic and latent infection of these cells.
|

|
This has further implications for neuroinflammatory diseases such as multiple sclerosis, where both cells bearing CCR1/CCR5 plus their ligands, as well as HHV-6A, have been linked.

We reported previously that administration of MIP-1alpha mobilized a population of F4/80(-)B220(-)CD11c+ DC precursors into peripheral blood by the expression of CCR1 and CCR5.
|
16 |
18791167
|
In this study, we identified a new subset of CCR6+CCR1(-)CCR5(-)B220(-)CD11c(+) cells in MIP-1alpha-administered mice.
|
17 |
18791167
|
When cultured with GM-CSF, IL-4, and TNF-alpha, these cells differentiated into mature DCs, possessing the typical morphologic characteristics, phenotypes, and antigen-presenting function (termed CCR6+ DC precursors).
|
18 |
18791167
|
Taken together, this study further demonstrates the mechanism of DC precursor mobilization induced by MIP-1alpha; that is, besides mobilizing DC precursors with CCR1 and CCR5 expressions, MIP-1alpha recruited F4/80+CD11c(-) monocyte/macrophage-producing MIP-3alpha, which finally mobilized the CCR6+ DC precursor subset to amplify the B220(-)CD11c+ DC precursor population.

Pretreatment frequency of circulating IL-17+ CD4+ T-cells, but not Tregs, correlates with clinical response to whole-cell vaccination in prostate cancer patients.
|

|
Surface expression of the chemokine receptors CCR4 and CCR6 was used to further subdivide IL-17-producing cells into subsets with distinct homing properties.
|
21 |
19533748
|
The frequency of circulating regulatory T-cells (Tregs), defined as CD3(+)CD4(+)CD127(lo)Foxp3(+)CD25(+) was compared in the same patients.
|
22 |

|
The frequency of CCR4(-)IL-17(+)CD4(+) T-cells prevaccination inversely correlated with time to disease progression (TTP) in 23 prostate cancer patients.

We asked whether the efficacy of dendritic cell (DC) vaccination with the renal cell carcinoma Ags MAGE-A9 (MAGE9) and G250 could be strengthened by covaccination with the renal cell carcinoma autoantigen GOLGA4.
|
24 |
20548033
|
Autoantigen covaccination significantly strengthened tumor Ag-specific CD4(+) and CD8(+) T cell expansion, particularly in peptide-loaded DC-vaccinated mice.
|
25 |
20548033
|
Covaccination was accompanied by an increase in inflammatory cytokines, boosted IL-12 and IFN-gamma expression, and promoted a high tumor Ag-specific CTL response.
|
26 |
20548033
|
Concomitant autoantigen vaccination also supported CCR6, CXCR3, and CXCR4 upregulation and T cell recruitment into the tumor.

Induction of TLR4-dependent CD8+ T cell immunity by murine β-defensin2 fusion protein vaccines.

|
This enhanced expansion of class I restricted T cells was Toll-like receptor 4 (TLR4) dependent, but CC chemokine receptor 6 (CCR6) independent.
|

We have found that, even in the absence of CD4(+) T-cell help, vaccine-induced CD8(+) T cells persist and confer resistance against Blastomyces dermatitidis and Histoplasma capsulatum.

Although the role of T helper 17 cells in immunity to fungi is debated, IL-17 producing CD8(+) T cells (Tc17 cells) have not been investigated.
|
31 |
22829762
|
IL-6 was required for Tc17 differentiation and immunity, but IL-1R1 and Dectin-1 signaling was unexpectedly dispensable.
|
32 |
22829762
|
Tc17 cells expressed surface CXCR3 and CCR6, but only the latter was essential in recruitment to the lung.
|
33 |
22829762
|
Although IL-17 producing T cells are believed to be short-lived, effector Tc17 cells expressed low levels of KLRG1 and high levels of the transcription factor TCF-1, predicting their long-term survival and stem-cell like behavior.

We assessed the role of CCR5(+)/CCR6(+)/CD11b(+)/CD11c(+) dendritic cells (DCs) for induction of ovalbumin (OVA)-specific antibody (Ab) responses following mucosal immunization.
|
36 |
23565250
|
CD11b(+)/CD11c(+) DCs were markedly decreased in both CCR5(-/-) and CCR6(-/-) mice.
|
37 |
23565250
|
These results suggest that CCR5(+)CCR6(+) DCs play an important role in the induction of Ag-specific SIgA Ab responses.

In co-culture experiments we confirmed CXCR5+ cells from HIV-uninfected donors provide help to B cells and more specifically, we identified a CCR7(high)CXCR5(high)CCR6(high)PD-1(high) CD4 T cell population that secretes IL-21 and enhances isotype-switched immunoglobulin production.

Type 3 innate lymphoid cells (ILC3) are key players in antimicrobial defense in intestinal mucosa, through interleukin 17 and interleukin 22 (IL-22) production.
|
43 |
24577508
|
We first observed that lung mucosa harbors a discrete population of ILC3 expressing CD127, CD90, CCR6, and the transcriptional factor RORγt.
|
44 |
24577508
|
In addition, lung ILC3 were identified as a major source of IL-22 in response to interleukin 23 stimulation.
|
45 |
24577508
|
During Streptococcus pneumoniae infection, ILC3 rapidly accumulated in the lung tissue to produce IL-22.
|
46 |
24577508
|
In response to S. pneumoniae, dendritic cells and MyD88, an important adaptor of innate immunity, play critical functions in IL-22 production by ILC3.
|
47 |
24577508
|
Finally, administration of the Toll-like receptor 5 agonist flagellin during S. pneumoniae challenge exacerbated IL-22 production by ILC3, a process that protects against lethal infection.

Unlike humans, macaque mucosal memory B-cells lacked CD27 expression; only two sub-populations were present: naïve (CD21(+)CD27(-)) and tissue-like (CD21(-)CD27(-)) memory.
|
49 |
24814239
|
The homing markers CXCR4, CCR6, CCR9 and α4β7 were differentially expressed between naïve and tissue-like memory B-cells.
|
50 |
24814239
|
Mucosal plasmablasts were identified as CD19(+)CD20(+/-)HLA-DR(+)Ki-67(+)IRF4(+)CD138(+/-) and mucosal plasma cells as CD19(+)CD20(-)HLA-DR(-)Ki-67(-)IRF4(+)CD138(+).
|
51 |
24814239
|
Both populations were CD39(+/-)CD27(-).

Here we characterized rhesus macaque MZ B cells, present in secondary lymphoid tissue but not peripheral blood, as CD19(+), CD20(+), CD21(hi), IgM(+), CD22(+), CD38(+), BTLA(+), CD40(+), CCR6(+) and BCL-2(+).

Using CXCR5, CXCR3, CCR6, CCR7, PD1, and ICOS as markers, Tfh-like cells can be identified in the circulation and be classified into three functionally distinct subsets that are PD1+ICOS+, PD1+ ICOS-, or PD1-ICOS-.
|
54 |
26333070
|
We used these markers to identify different subsets of CXCR5+CD4+ Tfh-like cells in response to highly immunogenic and efficacious vaccines for human papillomaviruses (HPV): Cervarix and Gardasil.
|
55 |
26333070
|
PD1+ICOS+ CXCR3+CCR6-CXCR5+CD4+ (Tfh1-like) cells were induced and peaked on Day (D) 7 post-first vaccination, but not as much on D7 post-third vaccination.
|
56 |
26333070
|
We also observed a trend toward increase in PD1+ICOS+ CXCR3-CCR6-CXCR5+CD4+ (Tfh2-like) cells for both vaccines, and PD1+ICOS+ CXCR3-CCR6+CXCR5+CD4+ (Tfh17-like) subset was induced by Cervarix post-first vaccination.
|
57 |
26333070
|
We found frequencies of memory B cells at D30 correlated with anti-HPV16 and 18 antibody titers from D30, and the induction levels of memory B cells at D30 and PD1+ICOS+Tfh1-like cells at D7 post-first vaccination correlated for Cervarix.
|
58 |
26333070
|
Our study showed that induction of circulating CXCR5+CD4+ Tfh-like subsets can be detected following immunization with HPV vaccines, and potentially be useful as a marker of immunogenicity of vaccines.
