Abstract
BACKGROUND The Immunoscore (IS), which prognostically classifies stage I-III colon cancer (CC) patients, was evaluated in the International Duration Evaluation of Adjuvant Therapy (IDEA) France cohort study investigating 3 versus 6 months of oxaliplatin-based adjuvant chemotherapy in stage III CC patients. PATIENTS AND METHODS Densities of CD3+ and CD8+ T cells in the tumor and invasive margin were determined by immunohistochemistry, quantified by digital pathology, and converted to IS. Mismatch repair status was determined by immunohistochemistry or by pentaplex PCR. Prediction of disease-free survival (DFS) by IS was analyzed by a multivariable Cox regression model in each study arm. Harrell's C-statistics were used to investigate the IS performance. RESULTS Samples of 1322 patients were available. IS Low, Intermediate (Int), and High were observed in 43.6%, 47.0%, and 9.4% of patients, respectively. IS Low identified patients at higher risk of relapse or death compared with Int + High [hazard ratio (HR) = 1.54; 95% confidence interval (CI) 1.24-1.93, P = 0.0001]. The 3-year DFS was 66.80% (95% CI 62.23-70.94) for IS Low and 77.14% (95% CI 73.50-80.35) for IS Int + High. In multivariable analysis, IS remained significantly independently associated with DFS (P = 0.003) when adjusted for sex, histological grade, T/N stage, and microsatellite instability. For mFOLFOX6-treated patients (91.6% of the cohort), a statistical significant interaction was observed for the predictive value of IS for treatment duration (3 versus 6 months) in terms of DFS (P = 0.057). IS Int + High significantly predicted benefit of 6 months of treatment (HR = 0.53; 95% CI 0.37-0.75; P = 0.0004), including clinically low- and high-risk stage III CC (all P < 0.001). Conversely, patients with IS Low (46.4%) did not significantly benefit from the 6-month mFOLFOX6 versus the 3-month mFOLFOX6. CONCLUSIONS The prognostic value of IS for DFS was confirmed in patients with stage III CC treated with oxaliplatin-based chemotherapy. Its predictive value for DFS benefit of longer duration of mFOLFOX6 adjuvant treatment was found in IS Int + High. These results will be validated in an external independent cohort. CLINICALTRIALS.

Abstract
The fifth "Melanoma Bridge Meeting" took place in Naples, December 1-5th, 2015. The main topics discussed at this meeting were: Molecular and Immuno advances, Immunotherapies and Combination Therapies, Tumor Microenvironment and Biomarkers and Immunoscore. The natural history of cancer involves interactions between the tumor and the immune system of the host. The immune infiltration at the tumor site may be indicative of host response. Significant correlations were shown between the levels of immune cell infiltration in tumors and patient's clinical outcome. Moreover, incredible progress comes from the discovery of mutation-encoded tumor neoantigens. In fact, as tumors grow, they acquire mutations that are able to influence the response of patients to immune checkpoint inhibitors. It has been demonstrated that sensitivity to PD-1 and CTLA-4 blockade in patients with advanced NSCLC and melanoma was enhanced in tumors enriched for clonal neoantigens. The road ahead is still very long, but the knowledge of the mechanisms of immune escape, the study of tumor neo-antigens as well as of tumor microenvironment and the development of new immunotherapy strategies, will make cancer a more and more treatable disease.

Abstract
471 Background: To date the anatomic extent of tumor (TNM classifications) has been by far the most important factors to predict the prognosis of cancer patients. However, the impact of immune responses and tumor escape on patient prognosis in human cancer is poorly understood. Methods: We analyzed large retrospective cohorts of colorectal cancer patients. Results: We showed that tumors from human colorectal cancer with a high density of infiltrating memory and effector memory T-cells (T-EM) are less likely to disseminate to lymphovascular and perineural structures and to regional lymph-nodes (New Engl J Med, 2005). We showed that the combination of immune parameters associating the nature, the density, the functional orientation and the location of immune cells within the tumor was essential to accurately define the impact of the local host immune reaction on patients prognosis (Science, 2006). We proposed to define these immune criteria as “immune contexture.” Analysis of patients with early-stage colorectal cancer confirmed the major role of cyotoxic effector T cells in predicting the prognosis of the patients (J Clin Oncol, 2009). Investigation of the primary tumor microenvironment allowed us to uncover the association of favorable outcomes with efficient coordination of the intratumoral immune response. We described four major immune coordination profiles within primary tumors depending on the balance between tumor escape and immune coordination. Recent advances analyzing mechanisms responsible for lymphocytic infiltration will be discussed. Conclusions: The density and the immune-cell location within the tumor have a prognostic value that is superior of those of the TNM classifications. Tumor invasion is statistically dependent on the host-immune reaction. No significant financial relationships to disclose.

Abstract
F. Pagès, A. Berger, F. Zinzindohoué, A. Kirilovsky, J. Galon, W.-H. Fridman Lymph node dissection is an integral part of the surgical resection of colon cancers; it completes the wide regional resection of tumor and it allows prognostic evaluation through accurate staging. Studies have demonstrated an immune reaction to the tumoral site which attests to an ongoing dialog between the tumor and systemic defenses. The regional lymph nodes constitute an important first line of immune defense where initial host response is initiated or, inversely, they may participate in a local state of immunosuppression. This article reviews current knowledge on intra-tumoral and nodal immune status in colorectal cancers and attempts to evaluate the potential immunologic implications of lymph node dissection.

Abstract
Lymph node dissection is an integral part of the surgical resection of colon cancers; it completes the wide regional resection of tumor and it allows prognostic evaluation through accurate staging. Studies have demonstrated an immune reaction to the tumoral site which attests to an ongoing dialog between the tumor and systemic defenses. The regional lymph nodes constitute an important first line of immune defense where initial host response is initiated or, inversely, they may participate in a local state of immunosuppression. This article reviews current knowledge on intra-tumoral and nodal immune status in colorectal cancers and attempts to evaluate the potential immunologic implications of lymph node dissection.

Abstract
Glucocorticoids are the major immunomodulating hormones in the human body. Recently, increasing interest in androgens as immunomodulators has emerged. In particular, Dehydroepiandrosterone (DHEA) has been suggested as beneficial in the treatment of some autoimmune disorders. However, the action and role of testicular and adrenal androgens on human immune cells remains unclear. This is the first study to provide large-scale gene expression data on the action of different steroids (DHEA, glucocorticoids, and testosterone) on human peripheral blood mononuclear cells using the recently developed genomic-scale technology of microarrays. Novel computational tools and techniques such as Principal Component Analysis (PCA) were used for analysis, clustering and visualization. We have demonstrated that each steroid has its distinct gene expression profile, although DHEA and testosterone co-regulated most genes in a similar direction while glucocorticoids frequently regulated the same genes in an opposite direction. Our data suggest an important and a complex regulatory role for androgens on human immune cells that should be considered in androgen replacement or treatment strategies.

Abstract
Mutations in the extracellular domain of the 55-kD tumor-necrosis factor (TNF) receptor (TNFRSF1A), a key regulator of inflammation, define a periodic-fever syndrome, TRAPS (TNF receptor-associated periodic syndrome [MIM 142680]), which is characterized by attacks of fever, sterile peritonitis, arthralgia, myalgia, skin rash, and/or conjunctivitis; some patients also develop systemic amyloidosis. Elsewhere we have described six disease-associated TNFRSF1A mutations, five of which disrupt extracellular cysteines involved in disulfide bonds; four other mutations have subsequently been reported. Among 150 additional patients with unexplained periodic fevers, we have identified four novel TNFRSF1A mutations (H22Y, C33G, S86P, and c.193-14 G-->A), one mutation (C30S) described by another group, and two substitutions (P46L and R92Q) present in approximately 1% of control chromosomes. The increased frequency of P46L and R92Q among patients with periodic fever, as well as functional studies of TNFRSF1A, argue that these are low-penetrance mutations rather than benign polymorphisms. The c.193-14 G-->A mutation creates a splice-acceptor site upstream of exon 3, resulting in a transcript encoding four additional extracellular amino acids. T50M and c.193-14 G-->A occur at CpG hotspots, and haplotype analysis is consistent with recurrent mutations at these sites. In contrast, although R92Q also arises at a CpG motif, we identified a common founder chromosome in unrelated individuals with this substitution. Genotype-phenotype studies identified, as carriers of cysteine mutations, 13 of 14 patients with TRAPS and amyloidosis and indicated a lower penetrance of TRAPS symptoms in individuals with noncysteine mutations. In two families with dominantly inherited disease and in 90 sporadic cases that presented with a compatible clinical history, we have not identified any TNFRSF1A mutation, despite comprehensive genomic sequencing of all of the exons, therefore suggesting further genetic heterogeneity of the periodic-fever syndromes.

Abstract
We demonstrate that soluble CD16 (sCD16; soluble Fc gamma RIII), a natural ligand of CR3, inhibits the infection of monocytes by primary R5 HIV-1 strain opsonized with serum of seronegative individuals. Inhibition of monocyte infection by sCD16 was similar to that observed with anti-CR3 mAbs, indicating that opsonized HIV may use a CR3-dependent pathway for entry in monocytic cells. Cultured human monocytes express both CR3 (CD11b/CD18) and CCR5 receptors. RANTES, the natural ligand of CCR5, inhibited infection of monocytes with unopsonized HIV particles and partially that of monocytes infected with HIV particles opsonized with complement-derived fragments. Although HIV-infected monocytes from homozygous CCR5 Delta 32/Delta 32 (CCR5(-/-)) individuals produce low levels of p24, cells infected with opsonized particles produced higher levels of p24 than cells infected with unopsonized particles. Our results thus suggest that CR3 may represent an alternative coreceptor to CCR5 of opsonized primary R5 virus entry into monocytes/macrophages. We also observed that the concentration of sCD16 is greatly decreased in sera of HIV-infected patients with low lymphocyte CD4(+) counts. Taken together, our findings suggest that sCD16, present in plasma, may play an important role in controlling HIV-1 spread.

Abstract
BACKGROUND & AIMS Proper adrenal glucocorticoid secretion is crucial in the course of inflammatory diseases. However, the function and structure of the adrenal glands have not been examined in inflammatory bowel diseases. METHODS After induction of trinitrobenzene sulfonic acid (TNBS) colitis in SJL/J mice, plasma hormone and cytokine levels were measured, adrenal structure was analyzed by immunohistochemistry and electron microscopy, and adrenal cytokine/cytokine receptor expression were studied by RNase protection. RESULTS Adrenals of colitic animals were enlarged and hypervascularized. These animals had a marked increase in plasma corticosterone levels during the course of colitis (270 +/- 34 vs. 16 +/- 11 ng/mL; P < 0.0001) but only a modest elevation of their concurrent adrenocorticotropin levels (57 +/- 13 vs. 29 +/- 9 pmol/L; NS). On electron microscopy, adrenocortical cells showed ultrastructural signs of marked stimulation, and intra-adrenal lymphocytes were frequently found in direct contact with these cells. Concurrent plasma levels of interleukin (IL)-6, the major cytokine activating the hypothalamic-pituitary-adrenal axis, were markedly increased (495 +/- 131 vs. 20 +/- 1.5 pg/mL; P < 0.0001), and this cytokine directly stimulated corticosterone secretion by adrenocortical cells in vitro. Intra-adrenal expression of IL-6 in animals with colitis was increased 80-fold, and the IL-6 receptor subunits IL-6R alpha and gp130 were present in the adrenal cells. Treatment of animals with neutralizing anti-IL-6 antibody reduced the TNBS-induced growth and activation of the adrenal cortices. CONCLUSIONS Colitis is associated with a profound stimulation of adrenocortical cell function and glucocorticoid release. Direct immune-adrenal interactions seem to contribute to this activation of the adrenal glands during colitis.

Abstract
The autoinflammatory syndromes are systemic disorders characterized by apparently unprovoked inflammation in the absence of high-titer autoantibodies or antigen-specific T lymphocytes. One such illness, TNF-receptor-associated periodic syndrome (TRAPS), presents with prolonged attacks of fever and severe localized inflammation. TRAPS is caused by dominantly inherited mutations in TNFRSF1A (formerly termed TNFR1), the gene encoding the 55 kDa TNF receptor. All known mutations affect the first two cysteine-rich extracellular subdomains of the receptor, and several mutations are substitutions directly disrupting conserved disulfide bonds. One likely mechanism of inflammation in TRAPS is the impaired cleavage of TNFRSF1A ectodomain upon cellular activation, with diminished shedding of the potentially antagonistic soluble receptor. Preliminary experience with recombinant p75 TNFR-Fc fusion protein in the treatment of TRAPS has been favorable.

Abstract
Interleukin-2 (IL-2) activates several different families of tyrosine kinases, but precisely how these kinases interact is not completely understood. We therefore investigated the functional relationships among Jak3, Lck, and Syk in IL-2 signaling. We first observed that in the absence of Jak3, both Lck and Syk had the capacity to phosphorylate Stat3 and Stat5a. However, neither supported IL-2-induced STAT activation, nor did dominant negative alleles of these kinases inhibit. Moreover, pharmacological abrogation of Lck activity did not inhibit IL-2-mediated phosphorylation of Jak3 and Stat5a. Importantly, ligand-dependent Syk activation was dependent on the presence of catalytically active Jak3, whereas Lck activation was not. Interestingly, Syk functioned as a direct substrate of Jak1 but not Jak3. Additionally, Jak3 phosphorylated Jak1, whereas the reverse was not the case. Taken together, our data support a model in which Lck functions in parallel with Jak3, while Syk functions as a downstream element of Jaks in IL-2 signaling. Jak3 may regulate Syk catalytic activity indirectly via Jak1. However, IL-2-mediated Jak3/Stat activation is not dependent on Lck or Syk. While the essential roles of Jak1 and Jak3 in signaling by gammac-utilizing cytokines are clear, it will be important to dissect the exact contributions of Lck and Syk in mediating the effects of IL-2 and related cytokines.

Abstract
Familial Mediterranean fever (FMF) is a recessive disorder characterized by episodes of fever and neutrophil-mediated serosal inflammation. We recently identified the gene causing FMF, designated MEFV, and found it to be expressed in mature neutrophils, suggesting that it functions as an inflammatory regulator. To facilitate our understanding of the normal function of MEFV, we extended our previous studies. MEFV messenger RNA was detected by reverse transcriptase-polymerase chain reaction in bone marrow leukocytes, with differential expression observed among cells by in situ hybridization. CD34 hematopoietic stem-cell cultures induced toward the granulocytic lineage expressed MEFV at the myelocyte stage, concurrently with lineage commitment. The prepromyelocytic cell line HL60 expressed MEFV only at granulocytic and monocytic differentiation. MEFV was also expressed in the monocytic cell lines U937 and THP-1. Among peripheral blood leukocytes, MEFV expression was detected in neutrophils, eosinophils, and to varying degrees, monocytes. Consistent with the tissue specificity of expression, complete sequencing and analysis of upstream regulatory regions of MEFV revealed homology to myeloid-specific promoters and to more broadly expressed inflammatory promoter elements. In vitro stimulation of monocytes with the proinflammatory agents interferon (IFN) gamma, tumor necrosis factor, and lipopolysaccharide induced MEFV expression, whereas the antiinflammatory cytokines interleukin (IL) 4, IL-10, and transforming growth factor beta inhibited such expression. Induction by IFN-gamma occurred rapidly and was resistant to cycloheximide. IFN-alpha also induced MEFV expression. In granulocytes, MEFV was up-regulated by IFN-gamma and the combination of IFN-alpha and colchicine. These results refine understanding of MEFV by placing the gene in the myelomonocytic-specific proinflammatory pathway and identifying it as an IFN-gamma immediate early gene.

Abstract
Stat4 is a key transcription factor involved in promoting cell-mediated immunity, whose expression in mature cells has been reported to be restricted to T and NK cells. We demonstrate here, however, that Stat4 expression is not restricted to lymphoid cells. In their basal state, monocytes do not express Stat4. Upon activation, however, IFN-gamma- and LPS-treated monocytes and dendritic cells express high levels of Stat4. Monocyte-expressed Stat4 in humans is phosphorylated in response to IFN-alpha, but not IL-12. In contrast, the Th2 cytokines, IL-4 and IL-10, specifically down-regulate Stat4 expression in activated monocytes, while having little effect on Stat6 expression. Moreover, macrophages in synovial tissue obtained from patients with rheumatoid arthritis express Stat4 in vivo, suggesting a potential role in a prototypical Th1-mediated human disease. IFN-alpha-induced Stat4 activation in human monocytes represents a previously unrecognized signaling pathway at sites of Th1 inflammation.

Abstract
Glucocorticoids are widely used in the therapy of inflammatory, autoimmune, and allergic diseases. As the end-effectors of the hypothalamic-pituitary-adrenal axis, endogenous glucocorticoids also play an important role in suppressing innate and cellular immune responses. Previous studies have indicated that glucocorticoids inhibit Th1 and enhance Th2 cytokine secretion. IL-12 promotes Th1 cell-mediated immunity, while IL-4 stimulates Th2 humoral-mediated immunity. Here, we examined the regulatory effect of glucocorticoids on key elements of IL-12 and IL-4 signaling. We first investigated the effect of dexamethasone on IL-12-inducible genes and showed that dexamethasone inhibited IL-12-induced IFN-gamma secretion and IFN regulatory factor-1 expression in both NK and T cells. This occurred even though the level of expression of IL-12 receptors and IL-12-induced Janus kinase phosphorylation remained unaltered. However, dexamethasone markedly inhibited IL-12-induced phosphorylation of Stat4 without altering its expression. This was specific, as IL-4-induced Stat6 phosphorylation was not affected, and mediated by the glucocorticoid receptor, as it was antagonized by the glucocorticoid receptor antagonist RU486. Moreover, transfection experiments showed that dexamethasone reduced responsiveness to IL-12 through the inhibition of Stat4-dependent IFN regulatory factor-1 promoter activity. We conclude that blocking IL-12-induced Stat4 phosphorylation, without altering IL-4-induced Stat6 phosphorylation, appears to be a new suppressive action of glucocorticoids on the Th1 cellular immune response and may help explain the glucocorticoid-induced shift toward the Th2 humoral immune response.

Abstract
IL-12 is a critical immunoregulatory cytokine that promotes cell-mediated immune responses and the differentiation of naive CD4+ cells to Th1 cells; however, relatively few IL-12 target genes have been identified. To better clarify the molecular basis of IL-12 action, we set out to characterize genes up-regulated by IL-12, first by contrasting IL-12- and IFN-alpha-inducible genes. We identified several genes up-regulated by IL-12, namely, MIP-1alpha, MIP-1beta, IL-1RA, and IFN regulatory factor-1 (IRF-1). IRF-1 is a transcription factor regulated by IFNs that is also essential for Th1 responses. We demonstrated that IL-12 directly up-regulates IRF-1 to the same extent as IFN-alpha in normal human T cells and in NK cells. We showed that IL-12 had a direct effect on IRF-1, an effect not mediated indirectly by the induction of IFN-gamma production. Furthermore, IL-2 and IL-12 synergistically induced IRF-1, whereas IFN-alpha and IL-12 did not. The participation of STAT4 in the regulation of IRF-1 was demonstrated in two ways. First, STAT4 was required for the IL-12-dependent transactivation of an IRF-1 reporter construct, and second, STAT4 binding to the IRF-1 promoter was shown using EMSA. In contrast to IL-12, no up-regulation of IRF-1 was found in IL-4-stimulated cells, and IL-4 did not block IL-12-dependent up-regulation of IRF-1. Therefore, IRF-1 may be an important contributor to IL-12 signaling, and we speculate that the defective IL-12 responses seen in IRF-1-/- mice might be attributable, in part, to the absence of this transcription factor.

Abstract
CD16 (Fc gamma R type III), a low affinity IgG Fc receptor, is found in two forms, a transmembrane Fc gamma RIIIa expressed by NK cells and monocytes and a phosphatidylinositol-linked Fc gamma RIIIb present on neutrophils. Exposure of neutrophils to inflammatory signals induces a rapid loss of CD16 expression and release of a soluble form of CD16 (sCD16). Soluble CD16 circulates in plasma, levels being reduced in sera from patients with multiple myeloma. In the present manuscript the authors summarize work that aimed to better understand: (i) the role of proteinases in sCD16 production and CD16 membrane shedding; and (ii) the regulation of sCD16 levels in multiple myeloma patients and the possible biological consequences of its decrease in this disease. Soluble CD16 was purified from human serum. Its N-terminal sequencing demonstrated that it originates from neutrophil CD16 and its C-terminal sequencing showed that the cleavage site was between Val 196 and Ser 197, close to the membrane anchor. Analysis of the effect of protease inhibitors revealed that the cleavage leading to sCD16 production by PMA-activated neutrophils was metalloproteinase-dependent. In addition, membrane and sCD16 were sensitive to serine proteinases released by azurophil granules or added under purified form. The reduction of sCD16 levels that occurs in patients with multiple myeloma was associated with a slight decrease in circulating neutrophils, but not with a significant defect in sCD16 production by neutrophils, as detected in vitro. Moreover, addition of a recombinant sCD16 to plasmocytoma lines did not significantly modify their proliferation and Ig secretion.

Abstract
Using a snake toxin as a proteic antigen (Ag), two murine toxin-specific monoclonal antibodies (mAbs), splenocytes, and two murine Ag-specific T cell hybridomas, we showed that soluble protein A (SpA) from Staphylococcus aureus and protein G from Streptococcus subspecies, two Ig binding proteins (IBPs), not only abolish the capacity of the mAbs to decrease Ag presentation but also increase Ag presentation 20-100-fold. Five lines of evidence suggest that this phenomenon results from binding of an IBP-Ab-Ag complex to B cells possessing IBP receptors. First, we showed that SpA is likely to boost presentation of a free mAb, suggesting that the IBP-boosted presentation of an Ag in an immune complex results from the binding of IBP to the mAb. Second, FACS analyses showed that an Ag-Ab complex is preferentially targeted by SpA to a subpopulation of splenocytes mainly composed of B cells. Third, SpA-dependent boosted presentation of an Ag-Ab complex is further enhanced when splenocytes are enriched in cells containing SpA receptors. Fourth, the boosting effect largely diminishes when splenocytes are depleted of cells containing SpA receptors. Fifth, the boosting effect occurs only when IBP simultaneously contains a Fab and an Fc binding site. Altogether, our data suggest that soluble IBPs can bridge immune complexes to APCs containing IBP receptors, raising the possibility that during an infection process by bacteria secreting these IBPs, Ag-specific T cells may activate IBP receptor-containing B cells by a mechanism of intermolecular help, thus leading to a nonspecific immune response.

Abstract
Autosomal dominant periodic fever syndromes are characterized by unexplained episodes of fever and severe localized inflammation. In seven affected families, we found six different missense mutations of the 55 kDa tumor necrosis factor receptor (TNFR1), five of which disrupt conserved extracellular disulfide bonds. Soluble plasma TNFR1 levels in patients were approximately half normal. Leukocytes bearing a C52F mutation showed increased membrane TNFR1 and reduced receptor cleavage following stimulation. We propose that the autoinflammatory phenotype results from impaired downregulation of membrane TNFR1 and diminished shedding of potentially antagonistic soluble receptor. TNFR1-associated periodic syndromes (TRAPS) establish an important class of mutations in TNF receptors. Detailed analysis of one such mutation suggests impaired cytokine receptor clearance as a novel mechanism of disease.

Abstract
The immune system is an important target for the cytokine TGF-beta1, whose actions on lymphocytes are largely inhibitory. TGF-beta has been reported to inhibit IL-12- and IL-2-induced cell proliferation and IFN-gamma production by T cells and NK cells; however, the mechanisms of inhibition have not been clearly defined. It has been suggested by some studies that TGF-beta blocks cytokine-induced Janus kinase (JAK) and STAT activation, as in the case of IL-2. In contrast, other studies with cytokines like IFN-gamma have not found such an inhibition. The effect of TGF-beta on the IL-12-signaling pathway has not been addressed. We examined this and found that TGF-beta1 did not have any effect on IL-12-induced phosphorylation of JAK2, TYK2, and STAT4 although TGF-beta1 inhibited IL-2- and IL-12-induced IFN-gamma production. Similarly, but in contrast to previous reports, we found that TGF-beta1 did not inhibit IL-2-induced phosphorylation of JAK1, JAK3, and STAT5A. Furthermore, gel shift analysis showed that TGF-beta1 did not prevent activated STAT4 and STAT5A from binding to DNA. Our results demonstrate that the inhibitory effects of TGF-beta on IL-2- and IL-12-induced biological activities are not attributable to inhibition of activation of JAKs and STATs. Rather, our data suggest the existence of alternative mechanisms of inhibition by TGF-beta.

Abstract
Soluble forms of Fc gammaR type III (sFc gammaRIII or sCD16) are present in many biological fluids. Their main ligand is IgG in the form of complexes. In plasma, sCD16 essentially derive from cleavage of membrane CD16 (or Fc gammaRIII) present on neutrophils and, to a lesser extent, on NK cells. Determination of sCD16 serum level during monoclonal gammopathies has demonstrated markedly reduced levels in multiple myeloma and in monoclonal gammopathy of undetermined significance (MGUS) rapidly evolving to multiple myeloma, compared to stable MGUS or controls, indicating a prognostic value for this biological parameter. The biology and functions of sCD16 are described, together with the biological significance of modifications of the sCD16 serum level in monoclonal gammopathies.

Abstract
Soluble Fc gamma receptors are produced by cleavage of the membrane receptors or by alternative splicing. They are found in biologic fluids. After a brief description of the structure and mode of production of soluble Fc gamma R, we address the question of ligands and function of the soluble Fc gamma R by using recombinant molecules and transgenic animals. We show that soluble Fc gamma R are not only IgG-binding factors which interfere with, and block, Fc-dependent immune reactions but also molecules that interact, in vitro, with non-Ig-ligands such as CR3 and CR4 and are trigger or regulate immune functions via these receptors.

Abstract
CD16 (FcgammaR type III) is a low-affinity IgG Fc receptor (R) that exists in two isoforms, a transmembrane FcgammaRIIIa expressed by NK cells and monocytes, and a phosphatidylinositol-linked FcgammaRIIIb expressed by neutrophils. A soluble form of CD16 (sCD16) circulates in plasma. The cleavage site and the nature of the enzyme(s) involved in production of sCD16 were investigated. Soluble CD16 was purified to apparent homogeneity from human serum by eight steps, including anion exchange and immunoaffinity chromatography. Serum sCD16 was sequenced at both ends, as well as a recombinant form of sCD16 used as control. N-terminal sequencing demonstrated that serum sCD16 originates from neutrophil FcgammaRIIIb and C-terminal sequencing suggested that the cleavage site is between Val 196 and Ser 197, close to the membrane anchor. Addition of a hydroxamate-based inhibitor of Zn2+ metalloproteinases (RU36156) led to a dramatic decrease of sCD16 production by phorbol 12-myristate 13-acetate-activated neutrophils, whereas inhibitors of serine proteinases had no significant effect, showing the metalloproteinase dependence of this cleavage process.

Abstract
Four mouse anti-human Fc gamma RII (CD32) (6C4, 2B2, 3D3, 93.4) (IgG1, kappa) and one anti-human Fc gamma RIII (CD16) (7.5.4) IgG1, kappa) MAbs were raised. An in vitro switch variant, 7.5.4Sw50 (IgG2b, kappa), was also derived from the 7.5.4 MAb. 6C4, 2B2, and 3D3 MAbs bind both Fc gamma RIIa and Fc gamma RIIb isoforms. Two of them (6C4 and 2B2 MAbs) allow a complete blockade of the binding of immune complexes to Fc gamma RII. All three MAbs immunoprecipitate the receptor and bind both its glycosylated and nonglycosylated forms. The fourth anti Fc gamma RII MAb, 93.4, directed against the intracellular region of Fc gamma RIIa1/2, allows its detection by Western blotting only when it is not phosphorylated. The 7.5.4 MAb binds both Fc gamma RIIIa and Fc gamma RIIIb, can be used in Western blotting and does not inhibit aggregated IgG binding. ELISA using IV.3 (anti-Fc gamma RIIa1/2)/6C4 and 3G8 (anti-Fc gamma RIIIa/b)/7.5.4Sw50 MAb pairs make it possible to detect soluble Fc gamma RIIa1/2 and Fc gamma RIII, with a sensitivity of 200 pg/mL and 1 ng/mL, respectively. Surface plasmon resonance analyses indicated that the KD of two of the three anti-Fc gamma RII and of the anti-Fc gamma RIII are in the same order of magnitude (6C4: 0.78 nM, 2B2: 0.28 nM, 7.5.4: 0.47 nM). The anti-Fc gamma RII 3D3 MAb exhibits an off-rate constant higher than the 6C4 and 2B2 MAbs and a KD of 2.19 nM.

Abstract
Binding of the Fc region of IgG antibodies to low affinity Fc gamma receptors (Fc gammaR) triggers important effector functions in the immune system. The type IIIb Fc gammaR (Fc gammaRIIIb or CD16) is a heavily glycosylated protein anchored to the membrane of neutrophils by a glycosylphosphatidylinositol link. This receptor contributes to cell activation by IgG immune complexes. To better understand the nature of the ligand-receptor association, we have studied the affinity and kinetics of the interaction between human IgG subclasses and two soluble forms of Fc gammaRIIIb (sFc gammaRIIIb or sCD16) corresponding to the 188 N-terminal amino acids of the extracellular region of the receptor, a glycosylated one made in eucaryotic cells (euc.sCD16) and a non-glycosylated one (proc.sCD16) made in Escherichia coli. Experiments using a BIAcore instrument, to measure protein binding in real time, showed that monomeric human IgG1 and IgG3, but not IgG2, IgG4, IgA and divalent antigen-binding fragments (F(ab')2) of IgG1, bound to immobilized euc.sCD16 with an affinity constant (K(A)) of 1.3 +/- 0.6 x 10(6) M(-1) and 2.6 +/- 0.4 x 10(5) M(-1), respectively. The affinity constant of proc.sCD16 for human IgG1 was in the same range (1.1 +/- 0.2 x 10(6) M(-1)), whereas that for human IgG3 was twofold higher (4.2 +/- 0.4 x 10(5) M(-1)). The specificity of the non-glycosylated receptor for human IgG subclasses bound to Sepharose was IgG1 > IgG3 >> IgG4 >>> IgG2. Thus, the extracellular polypeptide of Fc gammaRIIIb dictates the interaction of the receptor with IgG subclasses although glycosylation plays an inhibitory role in the interaction with human IgG3.

Abstract
Fc gamma RIII (CD16), a low affinity FcR which binds IgG-containing immune-complexes, exists under membrane-associated forms and under a soluble form (sFc gamma RIII). The latter, present in biological fluids (serum, saliva), is generated by proteolytic cleavage of the two membrane-associated Fc gamma RIII isoforms, Fc gamma RIII-A (expressed by macrophages and NK cells) and Fc gamma RIII-B (expressed exclusively by neutrophils). Herein we demonstrate that dendritic cells (DCs), generated by culturing monocytes with GM-CSF and IL-4, bind biotinylated recombinant sFc gamma RIII. This binding is specific and involves the complement receptor CR3 (CD11b/CD18) and CR4 (CD11c/CD18). Indeed, preincubation of DCs with anti-CD11b and anti-CD11c mAbs decreased by 52% and 62% respectively the binding with sFc gamma RIII. Moreover, electron microscopy showed that binding of gold-labeled sFc gamma RIII to DCs maintained at 4 degrees C occurred within clathrin-coated pits. Once internalized, at 37 degrees C, sFc gamma RIII entered the endocytic pathway and reached the MHC class II compartments. Furthermore, DCs incubated for 48 h with multivalent sFc gamma RIII expressed increased levels of CD40, CD80, CD86, CD54, CD58, HLA class I and class II molecules and decreased levels of CD23 and CD32. These effects result in an increased capacity of DCs to trigger proliferative responses by CD4+ CD45RA+ allogeneic T cells. RT-PCR amplification demonstrated that incubation of DCs for 20 h in the presence of multivalent sFc gamma RIII induced the appearance of GM-CSF and IL-12 p40 mRNA. Among the cytokines constitutively expressed, IL-1 beta and IL-8 were strongly up-regulated whereas IL-6 and IL-12 p35 mRNA were increased to a lesser extent and the expression of MIP-1 alpha mRNA remained constant. Finally, ELISA tests demonstrated that DCs incubated with multivalent sFc gamma RIII secreted the cytokines IL-1 beta, IL-6, IL-8, GM-CSF and IL-12 p75. Thus, while becoming internalized sFc gamma RIII could affect the capacity of DCs to present antigens and, via the induction of accessory molecules and the release of the IL-12 p75 protein, could initiate Th1 type immune response.
