Abstract
Shortening of messenger RNA poly(A) tails, or deadenylation, is a rate-limiting step in mRNA decay and is highly regulated during gene expression. The incorporation of non-adenosines in poly(A) tails, or 'mixed tailing', has been observed in vertebrates and viruses. Here, to quantitate the effect of mixed tails, we mathematically modeled deadenylation reactions at single-nucleotide resolution using an in vitro deadenylation system reconstituted with the complete human CCR4-NOT complex. Applying this model, we assessed the disrupting impact of single guanosine, uridine or cytosine to be equivalent to approximately 6, 8 or 11 adenosines, respectively. CCR4-NOT stalls at the 0, -1 and -2 positions relative to the non-adenosine residue. CAF1 and CCR4 enzyme subunits commonly prefer adenosine but exhibit distinct sequence selectivities and stalling positions. Our study provides an analytical framework to monitor deadenylation and reveals the molecular basis of tail sequence-dependent regulation of mRNA stability.

Abstract
Unlike most RNA and DNA viruses that broadly stimulate mRNA decay and interfere with host gene expression, human cytomegalovirus (HCMV) extensively remodels the host translatome without producing an mRNA decay enzyme. By performing a targeted loss-of-function screen in primary human fibroblasts, we here identify the host CCR4-NOT deadenylase complex members CNOT1 and CNOT3 as unexpected pro-viral host factors that selectively regulate HCMV reproduction. We find that the scaffold subunit CNOT1 is specifically required for late viral gene expression and genome-wide host responses in CCR4-NOT-disrupted cells. By profiling poly(A)-tail lengths of individual HCMV and host mRNAs using nanopore direct RNA sequencing, we reveal poly(A)-tails of viral messages to be markedly longer than those of cellular mRNAs and significantly less sensitive to CCR4-NOT disruption. Our data establish that mRNA deadenylation by host CCR4-NOT is critical for productive HCMV replication and define a new mechanism whereby herpesvirus infection subverts cellular mRNA metabolism to remodel the gene expression landscape of the infected cell. Moreover, we expose an unanticipated host factor with potential to become a therapeutic anti-HCMV target.

Abstract
In response to the host environment, the human pathogen Cryptococcus neoformans must rapidly reprogram its translatome from one which promotes growth to one which is responsive to host stress. In this study, we investigate the two events which comprise translatome reprogramming: the removal of abundant, pro-growth mRNAs from the translating pool, and the regulated entry of stress-responsive mRNAs into the translating pool. Removal of pro-growth mRNAs from the translating pool is controlled primarily by two regulatory mechanisms, repression of translation initiation via Gcn2, and decay mediated by Ccr4. We determined that translatome reprogramming in response to oxidative stress requires both Gcn2 and Ccr4, whereas the response to temperature requires only Ccr4. Additionally, we assessed ribosome collision in response to host-relevant stress and found that collided ribosomes accumulated during temperature stress but not during oxidative stress. The phosphorylation of eIF2α that occurred as a result of translational stress led us to investigate the induction of the integrated stress response (ISR). We found that eIF2α phosphorylation varied in response to the type and magnitude of stress, yet all tested conditions induced translation of the ISR transcription factor Gcn4. However, Gcn4 translation did not necessarily result in canonical Gcn4-dependent transcription. Finally, we define the ISR regulon in response to oxidative stress. In conclusion, this study begins to reveal the translational regulation in response to host-relevant stressors in an environmental fungus which is capable of adapting to the environment inside the human host. IMPORTANCE Cryptococcus neoformans is a human pathogen capable of causing devastating infections. It must rapidly adapt to changing environments as it leaves its niche in the soil and enters the human lung. Previous work has demonstrated a need to reprogram gene expression at the level of translation to promote stress adaptation. In this work, we investigate the contributions and interplay of the major mechanisms that regulate entry of new mRNAs into the pool (translation initiation) and the clearance of unneeded mRNAs from the pool (mRNA decay). One result of this reprogramming is the induction of the integrated stress response (ISR) regulon. Surprisingly, all stresses tested led to the production of the ISR transcription factor Gcn4, but not necessarily to transcription of ISR target genes. Furthermore, stresses result in differential levels of ribosome collisions, but these are not necessarily predictive of initiation repression as has been suggested in the model yeast.

Abstract
The CCR4-NOT complex acts as a central player in the control of mRNA turnover and mediates accelerated mRNA degradation upon HDAC inhibition. Here, we explored acetylation-induced changes in the composition of the CCR4-NOT complex by purification of the endogenously tagged scaffold subunit NOT1 and identified RNF219 as an acetylation-regulated cofactor. We demonstrate that RNF219 is an active RING-type E3 ligase which stably associates with CCR4-NOT via NOT9 through a short linear motif (SLiM) embedded within the C-terminal low-complexity region of RNF219. By using a reconstituted six-subunit human CCR4-NOT complex, we demonstrate that RNF219 inhibits deadenylation through the direct interaction of the α-helical SLiM with the NOT9 module. Transcriptome-wide mRNA half-life measurements reveal that RNF219 attenuates global mRNA turnover in cells, with differential requirement of its RING domain. Our results establish RNF219 as an inhibitor of CCR4-NOT-mediated deadenylation, whose loss upon HDAC inhibition contributes to accelerated mRNA turnover.

Abstract
Molecular left-right (L-R) asymmetry is established at the node of the mouse embryo as a result of the sensing of a leftward fluid flow by immotile cilia of perinodal crown cells and the consequent degradation of Dand5 mRNA on the left side. We here examined how the fluid flow induces Dand5 mRNA decay. We found that the first 200 nucleotides in the 3' untranslated region (3'-UTR) of Dand5 mRNA are necessary and sufficient for the left-sided decay and to mediate the response of a 3'-UTR reporter transgene to Ca2+, the cation channel Pkd2, the RNA-binding protein Bicc1 and their regulation by the flow direction. We show that Bicc1 preferentially recognizes GACR and YGAC sequences, which can explain the specific binding to a conserved GACGUGAC motif located in the proximal Dand5 3'-UTR. The Cnot3 component of the Ccr4-Not deadenylase complex interacts with Bicc1 and is also required for Dand5 mRNA decay at the node. These results suggest that Ca2+ currents induced by leftward fluid flow stimulate Bicc1 and Ccr4-Not to mediate Dand5 mRNA degradation specifically on the left side of the node.

Abstract
Pumilio paralogs, PUM1 and PUM2, are sequence-specific RNA-binding proteins that are essential for vertebrate development and neurological functions. PUM1&2 negatively regulate gene expression by accelerating degradation of specific mRNAs. Here, we determined the repression mechanism and impact of human PUM1&2 on the transcriptome. We identified subunits of the CCR4-NOT (CNOT) deadenylase complex required for stable interaction with PUM1&2 and to elicit CNOT-dependent repression. Isoform-level RNA sequencing revealed broad coregulation of target mRNAs through the PUM-CNOT repression mechanism. Functional dissection of the domains of PUM1&2 identified a conserved amino-terminal region that confers the predominant repressive activity via direct interaction with CNOT. In addition, we show that the mRNA decapping enzyme, DCP2, has an important role in repression by PUM1&2 amino-terminal regions. Our results support a molecular model of repression by human PUM1&2 via direct recruitment of CNOT deadenylation machinery in a decapping-dependent mRNA decay pathway.

Abstract
Chimeric antigen receptor (CAR) T cell therapy faces a number of challenges for the treatment of non-small-cell lung carcinoma (NSCLC), and efficient migration of circulating CAR T cells plays an important role in anti-tumor activity. In this study, a CAR specific for tumor antigen mesothelin (Msln-CAR) was co-expressed with cell chemokine receptors CCR2b or CCR4. Findings showed that CCR2b and CCR4 enhanced the migration of Msln-CAR T cell in vitro by transwell assay. When incubated with mesothelin-positive tumor cells, Msln-CCR2b-CAR and Msln-CCR4-CAR T cell specifically exerted potent cytotoxicity and produced high levels of proinflammatory cytokines, including IL-2, IFN-γ, and TNF-α. Furthermore, NSCLC cell line-derived xenograft (CDX) model was constructed by implanting subcutaneously modified A549 into NSG mice. Compared to conventional Msln-CAR T cells, living imaging indicated that Msln-CCR2b-CAR T cells displayed superior anti-tumor function due to enhanced migration and infiltration into tumor tissue shown by immunohistochemistry (IHC) analysis. In addition, histopathological examinations of mice organs showed that no obvious organic damages were observed. This is the first time that CAR T cell therapy combined with chemokine receptor is applied to NSCLC treatment.

Abstract
Human GW182 family proteins have Argonaute (AGO)-binding domains in their N-terminal regions and silencing domains, which interact with RNA silencing-related proteins, in their C-terminal regions. Thus, they function as scaffold proteins between the AGO protein and RNA silencing-related proteins, such as carbon catabolite repressor4-negative on TATA (CCR4-NOT) or poly(A)-binding protein (PABP). Our mass spectrometry analysis and the phosphorylation data registered in PhosphoSitePlus, a post-translational modification database, suggested that the C-terminal region of a human GW182 family protein, TNRC6A, has at least four possible phosphorylation sites, which are located near the region interacting with the CCR4-NOT complex. Among them, two serine residues at amino acid positions 1332 and 1346 (S1332 and S1346) were certainly phosphorylated in human HeLa cells, but other two serine residues (S1616 and S1691) were not phosphorylated. Furthermore, it was revealed that the phosphorylation patterns of TNRC6A affect the interaction with the CCR4-NOT complex. When S1332 and S1346 were dephosphorylated, the interactions of TNRC6A with the CCR4-NOT complex were enhanced, and when S1616 and S1691 were phosphorylated, such interaction was suppressed. Thus, phosphorylation of TNRC6A was considered to regulate the interaction with RNA silencing-related factors that may affect RNA silencing activity.

Abstract
Kaposi's sarcoma (KS) tends to occur in injured or inflamed sites of the body, which is described as the "Koebner phenomenon". KS is also unique in its extraordinary angio-hyperplastic inflammatory phenotype. Recently, evidence has accrued indicating that KS may derive from KSHV-infected mesenchymal stem cells (MSCs), which possess enhanced migration and homing ability. Inspired by these findings, we hypothesized that KS may arise from KSHV-infected MSCs that chemotactically migrate to preexisting inflammatory or injured sites. Here we report that KSHV infection of human MSCs significantly up-regulated expression of several chemokine receptors and enhanced cell migration ability in vitro. Furthermore, using a wound mouse model, we demonstrated that KSHV infection dramatically promotes MSCs migrating and settling in the wound sites. In addition, two mice in the KSHV-infected group showed purpura and tumors with KS-like features. Taken together, KSHV-enhanced MSC migration ability and inflammatory microenvironment play crucial roles in KS development.

Abstract
Contact hypersensitivity (CHS) is an established animal model for allergic contact dermatitis. Dendritic cells (DCs) play an important role in the sensitization phase of CHS by initiating T cell responses to topically applied haptens. The cannabinoid receptors 1 (CB1) and 2 (CB2) modulate DC functions and inflammatory skin responses, but their influence on the capacity of haptenized DCs to induce CHS is still unknown. We found lower CHS responses to 2,4-dinitro-1-fluorobenzene (DNFB) in wild type (WT) mice after adoptive transfer of haptenized Cnr2-/- and Cnr1-/-/Cnr2-/- bone marrow (BM) DCs as compared to transfer of WT DCs. In contrast, induction of CHS was not affected in WT recipients after transfer of Cnr1-/- DCs. In vitro stimulated Cnr2-/- DCs showed lower CCR7 and CXCR4 expression when compared to WT cells, while in vitro migration towards the chemokine ligands was not affected by CB2. Upregulation of MHC class II and co-stimulatory molecules was also reduced in Cnr2-/- DCs. This study demonstrates that CB2 modulates the maturation phenotype of DCs but not their chemotactic capacities in vitro. These findings and the fact that CHS responses mediated by Cnr2-/- DCs are reduced suggest that CB2 is a promising target for the treatment of inflammatory skin conditions.

Abstract
Chemokine-like factor 1 (CKLF1) is a potential target for ischemic stroke therapy. The NOD-like receptor protein 3 (NLRP3) inflammasome has been postulated to mediate inflammatory responses during ischemic/reperfusion (I/R) injury. The compound IMM-H004 is a novel coumarin derivative that can improve cerebral I/R injury. This study aims to investigate the effects of IMM-H004 on ischemia stroke injury and further elucidate the molecular mechanisms. The standard pMCAO model of focal ischemia was used in this paper. Drugs were administered at 6 hours after ischemia, and behavioral assessment, euthanasia, and outcome measures were evaluated at 9 hours after ischemia. The effects of IMM-H004 on ischemic stroke injury were determined using 2,3,5-triphenyltetrazolium chloride (TTC) staining, behavioral tests, enzyme-linked immunosorbent assay (ELISA), and Nissl staining. Immunohistologic staining, immunofluorescence staining, quantitative RT-PCR (qPCR), western blotting, and coimmunoprecipitation (CO-IP) assays were used to elucidate the underlying mechanisms. IMM-H004 treatment provided significant protection against ischemia stroke through a CKLF1-dependent anti-inflammatory pathway in rats. IMM-H004 downregulated the amount of CKLF1 binding with C-C chemokine receptor type 4, further suppressing the activation of NLRP3 inflammasome and the following inflammatory response, ultimately protecting the ischemic brain. This preclinical study established the efficacy of IMM-H004 as a potential therapeutic medicine for permanent cerebral ischemia. These results support further efforts to develop IMM-H004 for human clinical trials in acute cerebral ischemia, particularly for patients who are not suitable for reperfusion therapy.

Abstract
Atypical chemokine receptor 4 (ACKR4) is regulated by cytokines, binds chemokines and regulates the chemokine gradient. We verified the cDNA sequence by confirming ACKR4 from red sea bream (PmACKR4) by next generation sequencing (NGS) and analysed the molecular characteristics and gene expression profile. In the analysis using the predicted amino acid sequence of PmACKR4, a highly conserved G protein-coupled receptor 1 region and two cysteine residues were identified and included in the ACKR4 teleost cluster in the phylogenetic analysis. In healthy red sea bream, PmACKR4 mRNA was expressed at the highest levels in head kidney and was upregulated in all immune -related tissues used in the experiment after challenges with Streptococcus iniae (S. iniae) and red sea bream iridovirus (RSIV). These results suggest that ACKR4 is highly conserved in red sea bream and may play an important role in the immune system as previously reported. It is thought that ACKR4 acts as a regulator of immune -related cells via immune reactions after pathogenic infection.

Abstract
XRN1 is the major cytoplasmic exoribonuclease in eukaryotes, which degrades deadenylated and decapped mRNAs in the last step of the 5'-3' mRNA decay pathway. Metazoan XRN1 interacts with decapping factors coupling the final stages of decay. Here, we reveal a direct interaction between XRN1 and the CCR4-NOT deadenylase complex mediated by a low-complexity region in XRN1, which we term the 'C-terminal interacting region' or CIR. The CIR represses reporter mRNA deadenylation in human cells when overexpressed and inhibits CCR4-NOT and isolated CAF1 deadenylase activity in vitro. Through complementation studies in an XRN1-null cell line, we dissect the specific contributions of XRN1 domains and regions toward decay of an mRNA reporter. We observe that XRN1 binding to the decapping activator EDC4 counteracts the dominant negative effect of CIR overexpression on decay. Another decapping activator PatL1 directly interacts with CIR and alleviates the CIR-mediated inhibition of CCR4-NOT activity in vitro. Ribosome profiling revealed that XRN1 loss impacts not only on mRNA levels but also on the translational efficiency of many cellular transcripts likely as a consequence of incomplete decay. Our findings reveal an additional layer of direct interactions in a tightly integrated network of factors mediating deadenylation, decapping and 5'-3' exonucleolytic decay.

Abstract
CCR4/CAF1 are widely conserved deadenylases in eukaryotes. They form a large complex that includes NOT1 as a scaffold protein and various NOT proteins that are core components of multiple levels of gene expression control. The CCR4-NOT complex also contains several RNA-binding proteins as accessory proteins, which are required for target recognition by CCR4/CAF1 deadenylases. AtCCR4a/b, orthologs of human CCR4 in Arabidopsis, have various physiological effects. AtCCR4 isoforms are likely to have specific target mRNAs related to each physiological effect; however, AtCCR4 does not have RNA-binding capability. Therefore, identifying factors that interact with AtCCR4a/b is indispensable to understand its function as a regulator of gene expression, as well as the target mRNA recognition mechanism. Here, we identified putative components of the AtCCR4-NOT complex using co-immunoprecipitation in combination with mass spectrometry using FLAG-tagged AtCCR4b and subsequent verification with a yeast two-hybrid assay. Interestingly, four of 11 AtCAF1 isoforms interacted with both AtCCR4b and AtNOT1, whereas two isoforms interacted only with AtNOT1 in yeast two-hybrid assays. These results imply that Arabidopsis has multiple CCR4-NOT complexes with various combinations of deadenylases. We also revealed that the RNA-binding protein Arabidopsis Pumilio 5 and 2 interacted with AtCCR4a/b in the cytoplasm with a few foci.

Abstract
The mechanisms that enable immune evasion at metastatic sites are poorly understood. We show that the Polycomb Repressor Complex 1 (PRC1) drives colonization of the bones and visceral organs in double-negative prostate cancer (DNPC). In vivo genetic screening identifies CCL2 as the top prometastatic gene induced by PRC1. CCL2 governs self-renewal and induces the recruitment of M2-like tumor-associated macrophages and regulatory T cells, thus coordinating metastasis initiation with immune suppression and neoangiogenesis. A catalytic inhibitor of PRC1 cooperates with immune checkpoint therapy to reverse these processes and suppress metastasis in genetically engineered mouse transplantation models of DNPC. These results reveal that PRC1 coordinates stemness with immune evasion and neoangiogenesis and point to the potential clinical utility of targeting PRC1 in DNPC.

Abstract
Regulatory T cells (Treg) are critical mediators of immunosuppression in established tumors, although little is known about their role in restraining immunosurveillance during tumorigenesis. Here, we employ an inducible autochthonous model of melanoma to investigate the earliest Treg and CD8 effector T-cell responses during oncogene-driven tumorigenesis. Induction of oncogenic BRAFV600E and loss of Pten in melanocytes led to localized accumulation of FoxP3+ Tregs, but not CD8 T cells, within 1 week of detectable increases in melanocyte differentiation antigen expression. Melanoma tumorigenesis elicited early expansion of shared tumor/self-antigen-specific, thymically derived Tregs in draining lymph nodes, and induced their subsequent recruitment to sites of tumorigenesis in the skin. Lymph node egress of tumor-activated Tregs was required for their C-C chemokine receptor 4 (Ccr4)-dependent homing to nascent tumor sites. Notably, BRAFV600E signaling controlled expression of Ccr4-cognate chemokines and governed recruitment of Tregs to tumor-induced skin sites. BRAFV600E expression alone in melanocytes resulted in nevus formation and associated Treg recruitment, indicating that BRAFV600E signaling is sufficient to recruit Tregs. Treg depletion liberated immunosurveillance, evidenced by CD8 T-cell responses against the tumor/self-antigen gp100, which was concurrent with the formation of microscopic neoplasia. These studies establish a novel role for BRAFV600E as a tumor cell-intrinsic mediator of immune evasion and underscore the critical early role of Treg-mediated suppression during autochthonous tumorigenesis.Significance: This work provides new insights into the mechanisms by which oncogenic pathways impact immune regulation in the nascent tumor microenvironment.

Abstract
BACKGROUND Myocardial infarction (MI) is an irreversible damage of myocardial tissue caused by prolonged ischemia and hypoxia. A local hypoxia-induced inflammation causes recruitment of leukocytes to the inflammatory site to aid cardiac remodeling and tissue healing. Among various chemokines involved in the process, CCL22 plays an essential role in cardiac cell migrations. In this study, we evaluated the incidence of rs4359426 and rs2228428 SNPs in CCL22/CCR4 genes of MI patients and studied their association with the physiology of the disease. METHODS Two hundred patients aged 30 - 70 years diagnosed with myocardial infarction along with 200 agematched healthy controls were registered in the study and their pathophysiological findings were recorded. Genotypic analysis of rs4359426 and rs2228428 in CCL22 and CCR4 genes, respectively, were carried out in patients using PCR-RFLP method and compared with the control group. Successively genotyped SNPs were reviewed for their possible association with the disease or physiological findings using Fisher's exact test. RESULTS The frequency of CC genotypes atboth SNPs rs4359426 and rs2228428 in CCL22 and CCR4 genes was significantly higher in MI patients compared to other genotypes. CONCLUSIONS Although we could not establish any direct association with the disease due to restricted population size, it is possible that CC genotypesin CCL22 and CCR4 could be considered as risk factors in myocardial infarction.

Abstract
In the cytoplasm, small RNAs can control mammalian translation by regulating the stability of mRNA. In the nucleus, small RNAs can also control transcription and splicing. The mechanisms for RNA-mediated nuclear regulation are not understood and remain controversial, hindering the effective application of nuclear RNAi and investigation of its natural regulatory roles. Here, we reveal that the human GW182 paralogs TNRC6A/B/C are central organizing factors critical to RNA-mediated transcriptional activation. Mass spectrometry of purified nuclear lysates followed by experimental validation demonstrates that TNRC6A interacts with proteins involved in protein degradation, RNAi, the CCR4-NOT complex, the mediator complex, and histone-modifying complexes. Functional analysis implicates TNRC6A, NAT10, MED14, and WDR5 in RNA-mediated transcriptional activation. These findings describe protein complexes capable of bridging RNA-mediated sequence-specific recognition of noncoding RNA transcripts with the regulation of gene transcription.

Abstract
Chemokines are vital regulators of cell mobilization for immune surveillance, inflammation, and development. Chemokines signal through binding to their receptors that are a superfamily of seven-transmembrane domain G-coupled receptors. Recently, a complete repertoire of both CC and CXC chemokines have been identified in channel catfish, but nothing is known about their receptors. In this study, a set of 29 CC chemokine receptor (CCR) genes and 8 CXC chemokine receptor (CXCR) genes were identified and annotated from the channel catfish genome. Extensive phylogenetic and comparative genomic analyses were conducted to annotate these genes, revealing fish-specific CC chemokine receptors, and lineage-specific tandem duplications of chemokine receptors in the teleost genomes. With 29 genes, the channel catfish genome harbors the largest numbers of CC chemokine receptors among all the genomes characterized. Analysis of gene expression after bacterial infections indicated that the chemokine receptors were regulated in a gene-specific manner. Most differentially expressed chemokine receptors were up-regulated after Edwardsiella ictaluri and Flavobacterium columnare infection. Among which, CXCR3 and CXCR4 were observed to participate in immune responses to both bacterial infections, indicating their potential roles in catfish immune activities. In addition, CXCR3.2 was significantly up-regulated in ESC-susceptible fish, and CXCR4b was mildly induced in ESC-resistant fish, further supporting the significant roles of CXCR3 and CXCR4 in catfish immune responses. CXCR4b and CCR9a were both up-regulated not only after bacterial infection, but also after hypoxia stress, providing the linkage between bacterial infection and low oxygen stresses. These results should be valuable for comparative immunological studies and provide insights into their roles in disease and stress responses.

Abstract
CCL2 is a chemokine that can be induced during neuroinflammation to recruit immune cells, but its role in the central nervous system (CNS) is unclear. Our aim was to better understand its role. We induced CCL2 in CNS of naive CCL2-deficient mice using intrathecally administered replication-defective adenovirus and examined cell infiltration by flow cytometry. CCL2 expression induced pronounced and unexpected recruitment of regulatory and IFNγ-producing T cells to CNS from blood, possibly related to defective egress of monocytes from CCL2-deficient bone marrow. Infiltration also occurred in mice lacking CCR2, a receptor for CCL2. Expression of another receptor for CCL2, CCR4, and CXCR3, a receptor for CXCL10, which was also induced, were both increased in CCL2-treated CNS. CCR4 was expressed by neurons and astrocytes as well as CD4 T cells, and CXCR3 was expressed by CD4 and CD8 T cells. Chemokine-recruited T cells did not lead to CNS pathology. Our findings show a role for CCL2 in recruitment of CD4 T cells to the CNS and show that redundancy among chemokine receptors ensures optimal response.

Abstract
Objective To analyze the expressions of T cell receptor γ subfamily variable region I, II, and III genes (TRGV I~III) and prognosis-related chemokines and their receptor genes (CCL20, CCR6, CCL17, CCL22 and CCR4) in the peripheral blood of T-cell lymphoma (non-γδ T cell type) patients, and to investigate the correlations between γδ T cells and chemokines/receptors and their relevance to disease prognosis. Methods Peripheral blood samples were collected from 27 patients with T-cell lymphoma (non-γδ T cell type) and 9 healthy individuals as controls. Expressions of TRGV I~III subfamily genes and prognosis-related chemokines/receptors (CCL20/CCR6 and CCL17/CCL22/CCR4) in the peripheral blood of patients with T-cell lymphoma and normal controls were detected by quantitative real-time PCR. Results Compared with the normal controls, the expression levels of TRGV I-III subfamily genes of patients at the stages of initial onset, relapse/refractoriness and complete remission (CR) were significantly higher, and the expression patterns of TRGV subfamilies were changed. The expression levels of CCL22 and CCR4 in initial onset group and relapse/refractory group were significantly higher than that in normal controls, while CCL17 expression was significantly lower than that in normal controls. There were unique correlation patterns in the expressions of TRGV subfamily genes and chemokine/receptor genes in the patients at the stages of initial onset, CR and relapse/refractoriness. There are low expressions of TRGV II subfamilies in newly diagnosed and relapse/refractory T-cell lymphoma patients, and their expressions are elevated after treatment. Conclusion TRGV II subfamilies might be the T cell functional subset against T-cell lymphoma, and might be associated with the outcome of the disease. And the high expression of CCL22/CCR4 might be related to the pathogenesis of T-cell lymphoma.

Abstract
Elevated expression of the chemokine receptor CCR4 in tumors is associated with poor prognosis in several cancers. Here, we have determined that CCR4 was highly expressed in human renal cell carcinoma (RCC) biopsies and observed abnormal levels of CCR4 ligands in RCC patient plasma. An antagonistic anti-CCR4 antibody had antitumor activity in the RENCA mouse model of RCC. CCR4 inhibition did not reduce the proportion of infiltrating leukocytes in the tumor microenvironment but altered the phenotype of myeloid cells, increased NK cell and Th1 cytokine levels, and reduced immature myeloid cell infiltrate and blood chemokine levels. In spite of prominent changes in the myeloid compartment, the anti-CCR4 antibody did not affect RENCA tumors in T cell-deficient mice, and treatment with an anti-class II MHC antibody abrogated its antitumor activity. We concluded that the effects of the anti-CCR4 antibody required the adaptive immune system and CD4+ T cells. Moreover, CCL17-induced IFN-γ production was reduced when Th1-polarized normal CD4+ T cells were exposed to the CCR4 ligand, evidencing the involvement of CCR4 in Th1/Th2 regulation. The anti-CCR4 antibody, alone or in combination with other immune modulators, is a potential treatment approach to human solid cancers with high levels of CCR4-expressing tumor-infiltrating leukocytes and abnormal plasma CCR4 ligand levels.

Abstract
The objective of this study was to observe the distribution of regulatory T cells (Tregs) in the development of tongue squamous cell carcinoma (SCC) and to determine the role of Tregs in the progression of tongue SCC. A mouse model of 4-nitroquinoline-1-oxide (4NQO)-induced-tongue SCC was established. The expression of Forkhead box P3 (Foxp3), interleukin 10, transforming growth factor-β, chemokine CC motif ligands 17, 20, and CC chemokine receptor 4 was determined using real-time quantitative polymerase chain reaction. Foxp3 expression was also analyzed using immunohistochemistry. The results were compared with those of control mice and of 4NQO-treated mice treated with a cyclooxygenase-2 (COX-2) inhibitor. Well to moderately differentiated tongue SCC was induced in all of the experimental mice. The amount of Tregs of the experimental mice was over 10 times as much as control mice at the early stage of tumor progression. COX-2 inhibitor did not prevent the progression of tongue SCC and did not reduce the total amount of Tregs. Tregs function at the early stage of the development of tongue SCC, and it may be effective to suppress Tregs at the early stage of tumor progression for the treatment and/or prevention of tongue SCC.

Abstract
Chemokine-like factor 1 (CKLF1) is a newly cloned chemotactic cytokine with CCR4 being its functional receptor. Recent evidence demonstrates a role of CKLF1 in arthritis. The aim of this study was to quantify the expression of CKLF1 as well as assess the correlation between CKLF1 and plasma acute-phase markers. Synovium was obtained from 16 osteoarthritis (OA), 15 rheumatoid arthritis (RA) and 10 ankylosing spondylitis (AS) patients undergoing total joint arthroplasty, with other 11 patients treated for meniscal tears during sport accidents serving as normal controls. Levels of CKLF1 and CCR4 mRNA were detected by qRT-PCR, and the expression of CKLF1 was investigated by immunohistochemistry staining, subsequently analyzed with semiquantitative scores. Plasma acute-phase markers of inflammation were determined by ELISA. CKLF1 was found with a particularly up-regulated expression in synovim from AS and RA patients, and CCR4 mRNA levels increased in RA patients, not in OA or AS patients. Elevated levels of plasma markers of inflammation including CRP, ESR and D-dimer were observed in RA. Further, significantly positive correlations between relative expression levels of CKLF1 and CRP/ESR in RA patients and a positive correlation between CKLF1 and ESR in AS patients were found. There was no detectable correlation between CKLF1 and plasma D-dimer. This study confirms an increased but different level of CKLF1 in RA, OA and AS patients, all significantly higher than that in controls. Additionally, the significant positive correlations between CKLF1 levels and CRP/ESR in RA and between CKLF1 and ESR suggest that CKLF1 might contribute to the inflammation state and clinical symptoms in these rheumatic diseases. Further studies are required to investigate the utility of targeting specific CKLF1 for symptom control or disease modification in RA and AS.

Abstract
Accumulating evidence supports the role of an aberrant transcriptome as a driver of metastatic potential. Deadenylation is a general regulatory node for post-transcriptional control by microRNAs and other determinants of RNA stability. Previously, we demonstrated that the CCR4-NOT scaffold component Cnot2 is an inherited metastasis susceptibility gene. In this study, using orthotopic metastasis assays and genetically engineered mouse models, we show that one of the enzymatic subunits of the CCR4-NOT complex, Cnot7, is also a metastasis modifying gene. We demonstrate that higher expression of Cnot7 drives tumor cell autonomous metastatic potential, which requires its deadenylase activity. Furthermore, metastasis promotion by CNOT7 is dependent on interaction with CNOT1 and TOB1. CNOT7 ribonucleoprotein-immunoprecipitation (RIP) and integrated transcriptome wide analyses reveal that CNOT7-regulated transcripts are enriched for a tripartite 3'UTR motif bound by RNA-binding proteins known to complex with CNOT7, TOB1, and CNOT1. Collectively, our data support a model of CNOT7, TOB1, CNOT1, and RNA-binding proteins collectively exerting post-transcriptional control on a metastasis suppressive transcriptional program to drive tumor cell metastasis.

Abstract
Chemokines and chemokine receptors play important roles in the immune response. We previously reported the pathogenic role of C-C chemokine receptor type 4 (CCR4) in experimental autoimmune encephalomyelitis (EAE). Here, we examined whether CCR4 antagonism modulates the disease course of EAE. Wild-type and CCR4-knockout mice were induced EAE and were administered Compound 22, an antagonist of CCR4. Compound 22 significantly ameliorated the severity of EAE in wild-type mice, but not in the CCR4-knockout mice. Compound 22 inhibited Th1 and Th17 polarization of antigen-induced T-cell responses. Therefore, CCR4 antagonists might be potential therapeutic agents for multiple sclerosis.

Abstract
Traumas, infections, tumors, and some congenital malformations can lead to bone defects or even bone loss. The goal of the present study was to investigate whether inclusion of endothelial progenitor cells derived from peripheral blood (PB–EPCs) in cell-seeded partially deproteinized bone (PDPB) implants would stimulate recruitment of systemically injected bone marrow stromal cells (BMSCs) to the implant. Methods: BMSCs were injected intravenously with lentiviral expression vector expressing enhanced green fluorescent protein (eGFP) for tracing. Recruitment of eGFP-positive BMSCs was tested for the following implant configurations: 1) seeded with both BMSC and PB-EPC, 2) BMSC alone, 3) PB-EPC alone, and 4) unseeded PDPB. Protein and mRNA levels of endogenous stromal-derived factor-1 (SDF-1) and its receptor CXCR4, as well as monocyte chemotactic protein-1 (MCP-1) and its receptor CCR2, were evaluated on the 8th week. Immunohistochemical staining was performed to determine eGFP-positive areas at the defective sites. Masson’s trichrome staining was conducted to observe the distribution of collagen deposition and evaluate the extent of osteogenesis. Results: The mRNA and protein levels of SDF-1 and CXCR4 in the co-culture group were higher than those in other groups (p < 0.05) 8 weeks after the surgery. MCP-1 mRNA level in the co-culture group was also higher than that in the other groups (p < 0.05). Immunohistochemical assays revealed that the area covered by eGFP-positive cells was larger in the co-culture group than in the other groups (p < 0.05) after 4 weeks. Masson’s trichrome staining revealed better osteogenic potential of the co-culture group compared to the other groups (p < 0.05). Conclusion: These experiments demonstrate an association between PB-EPC and BMSC recruitment mediated by the SDF-1/CXCR4 axis that can enhance repair of bone defects.

Abstract
Sepsis is a deadly disease characterized by an overwhelming release of inflammatory mediators and the activation of different types of cells. This altered state of cell activation, termed leukocyte reprogramming, contributes to patient outcome. However, the understanding of the process underlying sepsis and the role of regulatory T cells (Tregs) in sepsis remains to be elucidated. In this study, we investigated the role of CCR4, the CCL17/CCL22 chemokine receptor, in the innate and acquired immune responses during severe sepsis and the role of Tregs in effecting the outcome. In contrast with wild-type (WT) mice subjected to cecal ligation and puncture (CLP) sepsis, CCR4-deficient (CCR4-/-) septic mice presented an increased survival rate, significant neutrophil migration toward the infection site, a low bacterial count in the peritoneum, and reduced lung inflammation and serum cytokine levels. Thus, a better early host response may favor an adequate long-term response. Consequently, the CCR4-/- septic mice were not susceptible to secondary fungal infection, in contrast with the WT septic mice. Furthermore, Tregs cells from the CCR4-/- septic mice showed reduced suppressive effects on neutrophil migration (both in vivo and in vitro), lymphocyte proliferation and ROS production from activated neutrophils, in contrast with what was observed for Tregs from the WT septic mice. These data show that CCR4 is involved in immunosuppression after severe sepsis and suggest that CCR4+ Tregs negatively modulate the short and long-term immune responses.

Abstract
Cellular chemotaxis is the best-known function of chemokine receptors which are closely linked with tumor metastasis. In fact, positive expression of chemokine receptors could also be identified even in some patients without metastatic tumors, while the clinical relevance of this data has not been fully established. Our studies were designed to clarify the CCR4 expression profiles and to explore its potential role in histologically node-negative (pN0) gastric cancer (GC). Immunohistochemistry (IHC) or immunohistofluorescence (IHF) analysis was performed on specimens obtained from 108 patients with pN0 GC. We found that CCR4 was aberrantly over-expressed inpN0 GC tissues, with different expression patterns on tumor cells and being associated with T-stage (P = 0.002). The matrigel in vitro invasion assay revealed that over-expression of CCR4 in GC cell lines significantly enhanced the invasive capacity of these cells. Results from real-time RT-PCR and gelatinzymography showed a significant increase in matrix metalloproteinase (MMP)-9 production induced by the forced expression of CCR4 in GC cell lines. Our data suggest that the aberrant CCR4 expression is involved in tumor invasion of pN0 GC and, conceivably, antagonists of CCR4 might be useful candidates for controlling early events in tumor progression.

Abstract
HIV-1 infection is characterized by an ongoing replication leading to T-lymphocyte decline which is paralleled by the switch from CCR5 to CXCR4 coreceptor usage. To predict coreceptor usage, several computer algorithms using gp120 V3 loop sequence data have been developed. In these algorithms an occupation of the V3 positions 11 and 25, by one of the amino acids lysine (K) or arginine (R), is an indicator for CXCR4 usage. Amino acids R and K dominate at these two positions, but can also be identified at positions 9 and 10. Generally, CXCR4-viruses possess V3 sequences, with an overall positive charge higher than the V3 sequences of R5-viruses. The net charge is calculated by subtracting the number of negatively charged amino acids (D, aspartic acid and E, glutamic acid) from the number of positively charged ones (K and R). In contrast to D and E, which are very similar in their polar and acidic properties, the characteristics of the R guanidinium group differ significantly from the K ammonium group. However, in coreceptor predictive computer algorithms R and K are both equally rated. The study was conducted to analyze differences in infectivity and coreceptor usage because of R-to-K mutations at the V3 positions 9, 10 and 11. V3 loop mutants with all possible RRR-to-KKK triplets were constructed and analyzed for coreceptor usage, infectivity and neutralization by SDF-1α and RANTES. Virus mutants R9R10R11 showed the highest infectivity rates, and were inhibited more efficiently in contrast to the K9K10K11 viruses. They also showed higher efficiency in a virus-gp120 paired infection assay. Especially V3 loop position 9 was relevant for a switch to higher infectivity when occupied by R. Thus, K-to-R exchanges play a role for enhanced viral entry efficiency and should therefore be considered when the viral phenotype is predicted based on V3 sequence data.

Abstract
C-C motif chemokine 22 (CCL22) C16A genetic variation (rs4359426) and C-C chemokine receptor type 4 (CCR4) C1014T variation (rs2228428) have been suggested to affect the expression level of the cognate proteins. Here we tried to investigate the plausible association of these polymorphisms with development of colorectal cancer. 165 patients with colorectal adenocarcinoma (age 54.4±13.4) and 150 age- and sex-matched healthy individuals were enrolled. Genotyping was performed by PCR-RFLP methods. Results indicated the frequency of 16A allele in CCL22 gene to be 31/330(9.4%) and 33/300(11%) in patients and controls, respectively (p=0.59). The frequencies of CC, CA, and AA genotypes at this locus were not significantly different between patients and controls (135/165; 81.8%, 29/165; 17.6%, 1/165; 0.6% in the patients and 121/150; 80.1%, 25/150; 16.6% and 4/150; 2.6% in the control group, p= 0.34). At the locus 1014 in CCR4, T allele was observed with the frequency of 107/330 (32.4%) and 83/300 (27.7%) in patients and controls, respectively (p=0.22). Analyses indicated no significant differences in the frequencies of CC, CT and TT genotypes at this locus between patients and controls (77/165; 46.7%, 69/165; 41.8% and 19/165; 11.5%; versus 83/150; 55.0%, 51/150; 33.8% and 16/150; 10.6%, respectively, p= 0.29). The presence of individual genotypes was not associated with clinicopathological characteristics of the disease, including tumor size, tumor grade and LN involvement (all with p<0.05). These findings collectively suggested that CCR4 C1014T and CCL22 C16A genetic variations were neither associated with the risk, nor with the progression of colorectal cancer in Iranian population.

Abstract
Homing of murine dendritic epidermal T cells (DETCs) from the thymus to the skin is regulated by specific trafficking receptors during late embryogenesis. Once in the epidermis, Vγ3δ1 TCR DETCs are maintained through self-renewal and participate in wound healing. GPR15 is an orphan G protein-linked chemoattractant receptor involved in the recruitment of regulatory T cells to the colon. Here we show that GPR15 is highly expressed on fetal thymic DETC precursors and on recently recruited DETCs, and mediates the earliest seeding of the epidermis, which occurs at the time of establishment of skin barrier function. DETCs in GPR15(-/-) mice remain low at birth, but later participation of CCR10 and CCR4 in DETC homing allows DETCs to reach near normal levels in adult skin. Our findings establish a role for GPR15 in skin lymphocyte homing and suggest that it may contribute to lymphocyte subset targeting to diverse epithelial sites.

Abstract
BACKGROUND Accumulating data suggest a role of chemokines in tumor cell metastasis. CCR4 has been implicated in hematologic malignancies and recently also in solid tumors. Herein, we hypothesized that CCR4 might be expressed and support migration of colon cancer cells. METHODS We used quantitative RT-PCR and flow cytometry to determine mRNA and surface expression of CCR4 on colon cancer cell lines (HT-29) and (AZ-97). Total RhoA and active RhoA protein levels in CCL17-stimulated colon cancer cells were quantified using ELISA and G-LISA assays. Migration assays were performed to evaluate colon cancer cells chemotaxis. In vitro tumor growth was assessed using proliferation assay. RESULTS Our results show clear-cut mRNA levels and surface expression of CCR4 on a colon cancer cell line (HT-29) and on tumor cells (AZ-97). CCR4 ligand CCL17 (TARC) was a potent stimulator of colon cancer cell migration. This CCL17-induced colon cancer cell migration was inhibited by pre-incubation of the colon cancer cells with an antibody directed against CCR4 or an antagonist against CCR4. CCL17-induced signaling in colon cancer cells revealed that CCL17 increased mRNA formation of RhoA-C in colon cancer cells. Our results also found that CCL17 increased total RhoA and active RhoA protein levels in colon cancer cells. The Rho-kinase inhibitor Y-27632 abolished CCL17-induced colon cancer cell chemotaxis. In addition, inhibition of isoprenylation by GGTI-2133 markedly reduced colon cancer cell migration triggered by CCL17. CONCLUSIONS Our novel data indicate for the first time that the CCL17-CCR4 axis might be involved in the spread of colon cancer cells.

Abstract
Thymocytes expressing the invariant Vγ5 γδT-cell receptor represent progenitors of dendritic epidermal T-cells (DETC) that play an important immune surveillance role in the skin. In contrast to the bulk of αβT-cell development, Vγ5(+) DETC progenitor development occurs exclusively in fetal thymus. Whilst αβT-cell development is known to require chemokine receptor mediated migration through distinct thymus regions, culminating in medullary entry and thymic egress, the importance and control of intrathymic migration for DETC progenitors is unclear. We recently revealed a link between Vγ5(+) DETC progenitor development and medullary thymic epithelial cells expressing Aire, a known regulator of thymic chemokine expression, demonstrating that normal Vγ5(+) DETC progenitor development requires regulated intramedullary positioning. Here we investigate the role of chemokines and their receptors during intrathymic Vγ5(+) DETC progenitor development and establishment of the DETC pool in the skin. We report that thymic medullary accumulation of Vγ5(+) DETC progenitors is a G-protein coupled receptor dependent process. However, this process occurs independently of Aire's influences on intrathymic chemokines, and in the absence of CCR4 and CCR7 expression by DETC progenitors. In contrast, analysis of epidermal γδT-cells at neonatal and adult stages in CCR4(-/-) mice reveals that reduced numbers of DETC in adult epidermis are not a consequence of diminished intrathymic embryonic development, nor deficiencies in initial epidermal seeding in the neonate. Collectively, our data reveal differences in the chemokine receptor requirements for intrathymic migration of αβ and invariant γδT-cells, and highlight a differential role for CCR4 in the maintenance, but not initial seeding, of DETC in the epidermis.

Abstract
OBJECTIVE To investigate the expression and function of thymus and activation regulated chemokine (TARC) and its special receptor CCR4 at placenta villous in the first trimester placenta villous. METHODS Placenta villous was collected from healthy women undergoing artificial abortion at 6 to 8 weeks of gestation. mRNA levels of TARC, CCR4 were analyzed using semi-quantitative reverse transcription (RT)-PCR methods. Immunohistochemistry assay was used to assess the protein localization and expression of TARC, CCR4. Additionally, extravillous cytotrophoblasts were isolated and cultured. Expression of TARC and CCR4 was measured by immunofluorescence assay. Invasion of cell line HTR8/SVneo was analyzed by transwell assay at concentration of 10, 25, 50 and 100 ng/ml of TARC matched with RPMI 1640 fetal bovine serum free culture medium as control group. In the mean time, blocking experiment was also added to detect TARC regulating cell invasion, which were classified into four groups: control, 100 ng/ml rhTARC, 20 µg/ml anti-TARC+100 ng/ml rhTARC, 100 ng/ml rhTARC+20 µg/ml IgG. The influence of 100 ng/ml TARC on expression level of integrin-α5 and integrin-β1 were measured by using western-blot assay. RESULTS (1) In vivo assay:expression of TARC and CCR4 mRNA were detectable in first trimester placenta villous, TARC protein was localized in cytotrophoblasts, syncytiotrophoblasts and cell column especially on the distal portion, while CCR4 protein was localized on invading interstitial cytotrophobalsts. (2) In vitro assay: a. TARC, CCR4 was also expressed in primary isolated extravillous cytotrophoblasts by immunofluorescence assay; b. Matrigel invasion assay demonstrated that TARC had specific dose dependent stimulatory effects on the cells invading through the matrigel precoated filter, the number of cells migration into the lower chamber were:142±31 at 10 ng/ml group, 161±46 at 25 ng/ml group, 201±30 at 50 ng/ml group, 312±48 at 100 ng/ml group, 117±33 at control group, the significant response observed from 25 ng/ml (P<0.05) and reached a peak effect at 100 ng/ml (P<0.01); c. Blocking experiment demonstrated that when trophoblast invasion was monitored in response to TARC neutralizing antibody (15 µg/ml) together with rhTARC 100 ng/ml. The stimulatory activity of rhTARC was completely overcome, with the cells invasion into the lower chambers were 100 ng/ml rhTARC, 20 µg/ml anti-TARC+100 ng/ml rhTARC, 100 ng/ml rhTARC+20 µg/ml IgG, control: 313±47, 113±41, 287±75 and 128±23, respectively; d. Western-blot assay demonstrated that if cells were treated with 100 ng/ml rhTARC, the expression of integrin-α5 were significantly increased (P<0.01), integrin-β1 level also increased when compared with control (P<0.05). CONCLUSION TARC was expressed specifically at human fetal-maternal interface. Trophoblast invasion and migration mainly was regulated by up-regulation integrin-α5 and integrin-β1, which plays an role in trophoblasts differentiation and placentation.

Abstract
Increasing evidence has shown that chemokines and chemokine receptors are associated with tumor growth and metastasis. CCR4, an important chemokine receptor for regulating immune homeostasis, is thought to be involved in hematologic malignancies and has also recently implicated in some solid tumors, such as gastric cancer. The possible role of CCR4 in breast cancer has not been well elucidated. In this study, we show that CCR4 is differentially expressed in human breast cancer cell lines. Specifically, we find that CCR4 is overexpressed in breast cancer cell lines with high metastatic potential. More importantly, we used a combination of overexpression and RNA interference to demonstrate that CCR4 promotes breast tumor growth and lung metastasis in mice. Furthermore, we find that microvessel density is significantly increased in tumors formed by CCR4-overexpressing cells and decreased in those formed by CCR4-knockdown cells. We find that overexpression of CCR4 can enhance the chemotactic response of breast cancer cells to CCL17. However, the expression of CCR4 does not affect the proliferation of breast cancer cells in vitro. Furthermore, we show that CCR4 expression is positively correlated with HER2 expression, tumor recurrence and lymph node, lung and bone metastasis (P < 0.05). Multivariate analysis showed that CCR4 expression is a significant independent prognostic factor for overall survival (P = 0.036) but not for disease-free survival in patients with breast cancer (P = 0.071). Survival analysis indicated a strong association between CCR4 expression and lower overall survival (P = 0.0001) and disease-free survival (P = 0.016) in breast cancer.

Abstract
BACKGROUND CC Chemokine receptor 4 (CCR4) is preferentially expressed on Th2 lymphocytes. CCR4-mediated inflammation may be important in the pathology of allergic rhinitis. Disruption of CCR4 - ligand interaction may abrogate allergen-induced inflammation. METHODS Sixteen allergic rhinitics and six nonatopic individuals underwent both allergen and control (diluent) nasal challenges. Symptom scores and peak nasal inspiratory flow were recorded. Nasal biopsies were taken at 8 h post challenge. Sections were immunostained and examined by light or dual immunofluorescence microscopy for eosinophils, T-lymphocytes, CCR4(+)CD3(+) and CXCR3(+)CD3(+) cells and examined by in situ hybridization for CCR4, IL-4 and IFN-gamma mRNA(+) cells. Peripheral blood mononuclear cells were obtained from peripheral blood of nine normal donors and the CCR4(+)CD4(+) cells assessed for actin polymerization in response to the CCR4 ligand macrophage-derived chemokine (MDC/CCL22) and the influence of a CCR4 antagonist tested. RESULTS Allergic rhinitics had increased early and late phase symptoms after allergen challenge compared to diluent; nonatopics did not respond to either challenge. Eosinophils, but not total numbers of CD3(+) T cells, were increased in rhinitics following allergen challenge. In rhinitics, there was an increase in CCR4(+)CD3(+) protein-positive cells relative to CXCR3(+)CD3(+) cells; CCR4 mRNA+ cells were increased and IL-4 increased to a greater extent than IFN-gamma. CCR4(+)CD4(+) T cells responded to MDC in vitro, and this response was inhibited by the selective CCR4 antagonist. CONCLUSION Lymphocyte CCR4 expression is closely associated with induction of human allergen-induced late nasal responses. Blocking CCR4-ligand interaction may provide a novel therapeutic approach in allergic disease.

Abstract
BACKGROUND Allergic inflammation is associated with Th2-type T cells, which can be suppressed by CD4+ CD25+ regulatory T cells (Tregs). Both express chemokine receptors (CCR) 4 and CCR8, but the dynamics of expression and effect of atopic status are unknown. OBJECTIVE To examine the expression of chemokine receptors by CD4+ CD25+ and CD4+ CD25- T cells from atopic and nonatopic donors, and document response to allergen stimulation in vitro. METHODS Chemokine receptor expression was examined by flow cytometry and quantitative PCR of CD4+ CD25hi and CD4+ CD25- T cells from atopics and nonatopics. Responsiveness to chemokines was by actin polymerization. Dynamics of chemokine receptor expression in 6-day allergen-stimulated cultures was analysed by carboxyfluoroscein succinimidyl ester labelling. RESULTS CD4+ CD25hi Tregs preferentially expressed CCR3, CCR4, CCR5, CCR6 and CCR8. CD4+ CD25hi Tregs responded to the chemokine ligands for CCR4, CCR6 and CCR8 (CCL17, 22, 20 and 1 respectively), with no differences between atopic and nonatopic donors. Over 6-day allergen stimulation, CD4+ CD25+ T-cells downregulated CCR4 and upregulated CCR7, in contrast to CD4+ CD25- effector cells, which downregulated CCR7 and upregulated CCR4. CONCLUSIONS CCR4, CCR6 and CCR8 have potential roles in localization of both CD4+ CD25+ regulatory and CD4+ CD25- effector T cells to sites of allergic inflammation. Upregulation of CCR7 and downregulation of CCR4 upon allergen stimulation of Tregs may allow their recirculation from sites of inflammation, in contrast to retention of effector T cells.

Abstract
T helper (Th) 17 cells are a distinct lineage of CD4+ T cells mediating tissue inflammation through the secretion of IL-17. In addition, it has been shown that the expression of the transcriptional factor RORgammat is responsible for the induction and maintenance of this cell line. Th17 cells are believed to be involved in a variety of autoimmune disorders, but may also play an important role in host defense. Here we describe a novel technique to reproducibly isolate viable Th17 cells based on their IL-17 secreting ability. We confirmed Th17 cell enrichment by quantitative PCR analysis and demonstrate that positively selected cells using this technique express significantly increased mRNA levels of RORgammat, IL-23 receptor and CCR4 when compared to negatively selected cells. Furthermore, we show that purified Th17 cells can be maintained in long-term culture and expand in vitro. In conclusion, this technique will allow for the first time the direct, ex vivo analysis of phenotypic and functional properties of Th17 cells.
