Abstract
In-depth immunophenotyping by flow cytometry of peripheral blood dendritic cell (DC) populations of psoriasis vulgaris without (PsO; N = 23) or with psoriatic arthritis (PsA; N = 15), before (T1) and after 12 months (T2) therapy with the anti-TNF drugs infliximab, etanercept, the anti-IL-17A secukinumab and the anti-IL12/IL-23 ustekinumab. Compared to healthy donors (N = 38), patients with PsA displayed lower frequencies of dendritic cell subsets pDC, cDC1 and cDC2, which were normalized following treatment except pDC. In contrast, patients with PsO only displayed lower frequencies of pDC which were normalized following treatment. Figure created with BioRender.com.

Abstract
PURPOSE/OBJECTIVE(S) Stereotactic body radiotherapy (SBRT) is an effective treatment for oligometastatic disease in multiple sites, however, the optimal radiation dose for long term local control of adrenal metastases has not yet been determined. The aim of this study is to evaluate outcomes of adrenal SBRT and to evaluate factors that correlate with local control MATERIALS/METHODS: After IRB approval, a retrospective data review of patients treated with SBRT on adrenal metastases was conducted, at a medical center in Israel between 2015 and 2021. Biologic Equivalent Dose (BED) were calculated using an alpha beta ration of 10. Kaplan Meier and Cox regression were calculated to describe the hazard ratio for local control and survival using statistical software. RESULTS Fifty-eight cases of adrenal SBRT were identified. The average age was 67 years (ranging 42-92). Forty-three percent of primary tumor was non-small cell lung cancer. The lesions were equally distributed between the right and left adrenal gland. Six patients had bilateral radiation treatment. Fifty-eight percent of the cases were in the setting of oligometastatic disease (less than 5 lesions) with the rest having progression in the adrenal. PET-CT scans were available for follow up in 55% of patients and CT in the rest. The average GTV volume was 42 cm2 respiratory control through 4D and breath hold was performed in 86% of cases. The median follow up time, for local control, was 10 months with a range of 1-54 mos. Univariate analysis local control, during the last follow up, was seen in 74% of cases. Total dosage was equal to or above 72 Gy and dosage per fraction was equal to or above 8 Gy. The use of respiratory motion was found significant for local control. Only a fraction size equal to or above 8 Gy and a total dosage equal to and above 72 Gy were found significant for local failure (HR = 0.26, p = 0.024 and HR = 0.28, p = 0.019). With multivariable analysis the dosage per fraction ≥8 Gy continued to be significant after adjusting for total dose, histology, side, and motion management. Two patients had clinical signs of adrenal insufficiency and both received bilateral adrenal radiation. Bowel toxicity was low: 1 patient had >G3 toxicity. CONCLUSION In the largest single institution series reported to date, we found unilateral adrenal SBRT to be safe, however, bilateral treatment harbors a risk of adrenal insufficiency. Dose per fraction ≥8 Gy was the most powerful predictor of local control, and a total dose ≥72gy and motion management were also significant. In conclusion, we propose a treatment regimen with a fraction size of at least 8 Gy and a total dosage of at least 72 Gy for evaluation, in a prospective clinical trial.

Abstract
PURPOSE/OBJECTIVE(S) Radiation induced lung fibrosis after lung SBRT include dense consolidation that may be dynamic over time and thus difficult to discern from local recurrence. We intended to evaluate the use of multi-parametric MRI to distinguish stereotactic Body Radiation Therapy (SBRT)- induced pulmonary fibrosis from local recurrence (LR). MATERIALS/METHODS In this prospective study we included SBRT treated non-small cell lung cancer (NSCLC) patients, with suspected of local recurrence by conventional imaging. The patients were consented, and underwent MR imaging: T2 weighted, diffusion weighted imaging (DWI) dynamic contrast enhancement (DCE) and 5-minute delayed T1 weighted imaging after contrast injection. On the date of the MRI the LR status was unknown. LR status was defined as recurrence within high dose-radiation field, and confirmed by biopsy and/or subsequent growth on follow-up imaging following the next 12 months. RESULTS The study included 18 patients with 20 irradiated lesions. MRI was conducted at a median of 23.5 months (range 6-55 months) from SBRT. Six lesions had MRI features suspicious for local recurrence that were confirmed by either biopsy (N = 3) or by follow-up imaging (N = 3) in the 12 months following the MRI. None of the lesions thought to be benign on MRI were shown to be malignant by biopsy (N = 1) or follow-up imaging (N = 13). All confirmed recurrences showed heterogeneous enhancement and had washout curves in the suspected focus which differed from the washout of the surrounding fibrosis. Enhancement of benign lesions was either homogenous or heterogeneous, but washout curves were similar in all regions. Apparent diffusion coefficient (ADC) mean values within the recurrence lesions was 1.21 10-3mm/s2 (range 0.98-1.7) which overlapped with the ADC range of fibrotic changes (mean 1.73 10-3mm/s2, range 0.98-2.6). CONCLUSION In this pilot prospective study of NSCLS patients treated with lung SBRT, multi-parametric chest MRI was able to correctly support suspicion of LR and correctly minimize suspicion in the benign changes. Confirmed recurrences showed heterogeneous enhancement and had washout curves in the suspected focus which differed from the washout of the surrounding fibrosis. Still, we could not identify one parameter that would be diagnostic by itself. Although lower apparent diffusion coefficient values were seen in the recurrent lesions, no absolute cut-off value could differentiate recurrent tumor from fibrosis.

Abstract
Background Psoriasis is a chronic immune-mediated skin disease with systemic inflammation and comorbidities. Although the disease severity may vary over time, many patients suffer from mild to moderate disease. Often local treatment will be sufficient to control the symptoms, but they may have several side effects. ω-3 polyunsaturated fatty acids have shown promising results in clinical trials with mild-to-moderate psoriasis. Methods We explored the impact of phospholipid bound docosahexaenoic acid and eicosapentaenoic acid in a 3:1 ratio on immune cells and cytokine networks in peripheral blood of patients with psoriasis. We investigated the inter-relation of plasma cytokine levels and disease severity in 58 patients, and explored the status of circulating immune cell activity in 18 patients with non-severe psoriasis before and during herring roe oil supplementation. Plasma concentration of 22 cytokines was measured by Luminex technology and circulating immune cells were analyzed by multicolor flow cytometry. Results CCL2 levels decreased over time, and IFN-γR1 increased, possibly related to the action of ω-3 polyunsaturated fatty acids. We observed a shift from naïve to effector CD4+ T cells and decreases of CD38 expression on CD4+ and CD8+ T cells, CD56bright NK cells and CD14+CD16- classical monocytes. Conclusions These findings support the beneficial effect of herring roe oil supplementation.

Abstract
We present an improved measurement of the carbon-nitrogen-oxygen (CNO) solar neutrino interaction rate at Earth obtained with the complete Borexino Phase-III dataset. The measured rate, R_{CNO}=6.7_{-0.8}^{+2.0} counts/(day×100 tonnes), allows us to exclude the absence of the CNO signal with about 7σ C.L. The correspondent CNO neutrino flux is 6.6_{-0.9}^{+2.0}×10^{8} cm^{-2} s^{-1}, taking into account the neutrino flavor conversion. We use the new CNO measurement to evaluate the C and N abundances in the Sun with respect to the H abundance for the first time with solar neutrinos. Our result of N_{CN}=(5.78_{-1.00}^{+1.86})×10^{-4} displays a ∼2σ tension with the "low-metallicity" spectroscopic photospheric measurements. Furthermore, our result used together with the ^{7}Be and ^{8}B solar neutrino fluxes, also measured by Borexino, permits us to disfavor at 3.1σ C.L. the "low-metallicity" standard solar model B16-AGSS09met as an alternative to the "high-metallicity" standard solar model B16-GS98.

BackgroundPrimary Sjögren’s syndrome (pSS) is a systemic autoimmune disease, characterized by mononuclear cell infiltrates in the salivary and lacrimal glands, leading to glandular atrophy and dryness. Patient heterogeneity and lack of knowledge regarding its pathogenesis makes pSS a difficult disease to manage.MethodsAn exploratory analysis using mass cytometry was conducted of MAPK/ERK and JAK/STAT signaling pathways in peripheral blood mononuclear cells (PBMC) from 16 female medication free pSS patients (8 anti-Sjögren’s syndrome-related antigen A negative/SSA- and 8 SSA+) and 8 female age-matched healthy donors after stimulation with interferons (IFNs).ResultsWe found significant differences in the frequencies of memory B cells, CD8+ T central and effector memory cells and terminally differentiated CD4+ T cells among the healthy donors and patient subgroups. In addition, we observed an upregulation of HLA-DR and CD38 in many cell subsets in the patients. Upon IFNα2b stimulation, slightly increased signaling through pSTAT1 Y701 was observed in most cell types in pSS patients compared to controls, while phosphorylation of STAT3 Y705 and STAT5 Y694 were slightly reduced. IFNγ stimulation resulted in significantly increased pSTAT1 Y701 induction in conventional dendritic cells (cDCs) and classical and non-classical monocytes in the patients. Most of the observed differences were more prominent in the SSA+ subgroup, indicating greater disease severity in them.ConclusionsAugmented activation status of certain cell types along with potentiated pSTAT1 Y701 signaling and reduced pSTAT3 Y705 and pSTAT5 Y694 induction may predispose pSS patients, especially the SSA+ subgroup, to upregulated expression of IFN-induced genes and production of autoantibodies. These patients may benefit from therapies targeting these pathways.

Abstract
OBJECTIVE Primary Sjögren's syndrome (pSS) is the second most frequent systemic autoimmune disease affecting 0.1% of the general population. To characterize the molecular and clinical variability across pSS patients, we integrated transcriptomic, proteomic, cellular and genetic data with clinical phenotypes in a cohort of 351 pSS patients. METHODS Blood transcriptomes and genotypes of 351 pSS patients from a multi-center prospective clinical cohort were analyzed. Replication of the transcriptomic results was performed using 3 independent cohorts (n=462 patients). Circulating IFN-alpha (IFNɑ) and IFN-gamma (IFNγ) protein concentrations were determined using digital ELISA. RESULTS Transcriptomic analysis of the prospective cohort showed a strong IFN gene signature in more than half of the patients. This finding was replicated in three independent cohorts. As gene expression analysis did not discriminate between type I and II interferons, we applied digital ELISA to demonstrate that the IFN transcriptomic signature was driven by circulating IFNɑ, and not IFNγ, protein levels. IFNɑ protein levels, detectable in 75% of patients, were significantly associated with clinical and immunological features of disease activity at enrollment, and with increased frequency of systemic complications during the 5-year follow-up. Genetic analysis revealed a significant association between IFNɑ protein levels, a MHC-II haplotype and anti-SSA antibody. Additional cellular analysis revealed that a MHC-II HLA-DQ locus acts through upregulation of HLA II molecules on conventional DCs. CONCLUSIONS The present analysis identified the predominance of IFNα as driver of pSS variability and revealed an association with HLA gene polymorphisms.

Abstract
Background Interleukin-2 (IL-2) and the high-affinity IL-2 receptor (IL-2R) are essential for the survival of regulatory T cells (Tregs) which are the main players in immune tolerance and prevention of autoimmune diseases. Sjögren’s syndrome (SS) is a chronic autoimmune disease predominantly affecting women and is characterised by sicca symptoms including oral and ocular dryness. The aim of this study was to investigate an association between IL-2R and Treg function in patients with SS of different severity defined by the salivary flow rate. Methods In a cross-sectional study, we determined plasma soluble IL-2R (sIL-2R) levels in women with SS (n=97) and healthy females (n=50) using ELISA. A subset of those (n=51) was screened for Treg function measured by the STAT5 signalling response to IL-2 using phospho-flow cytometry. Results We found that elevated plasma levels of sIL-2R were positively associated with the severity of SS reflected by a pathologically low salivary flow. Phospho-flow analysis revealed that patients with SS have a significantly lower frequency of pSTAT5+ Tregs upon IL-2 stimulation compared with healthy individuals, while the frequency of Tregs and pSTAT5 in conventional T cells remained unchanged. In addition, we observed more pSTAT5+ Tregs at baseline in patients with SS, which is significantly associated with seropositivity and elevated sIL-2R. Conclusions Our data indicates that Tregs have a weakened immunosuppressive function in patients with SS due to impaired IL-2/IL-2R signalling capacity. This could mediate lymphocytic infiltration into salivary glands inducing sicca symptoms. We believe that sIL-2R could act as a useful indicator for SS and disease severity.

Abstract
We report the measurement of sub-MeV solar neutrinos through the use of their associated Cherenkov radiation, performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso. The measurement is achieved using a novel technique that correlates individual photon hits of events to the known position of the Sun. In an energy window between 0.54 to 0.74 MeV, selected using the dominant scintillation light, we have measured 10 887_{-2103}^{+2386}(stat)±947(syst) (68% confidence interval) solar neutrinos out of 19 904 total events. This corresponds to a ^{7}Be neutrino interaction rate of 51.6_{-12.5}^{+13.9} counts/(day·100 ton), which is in agreement with the standard solar model predictions and the previous spectroscopic results of Borexino. The no-neutrino hypothesis can be excluded with >5σ confidence level. For the first time, we have demonstrated the possibility of utilizing the directional Cherenkov information for sub-MeV solar neutrinos, in a large-scale, high light yield liquid scintillator detector. This measurement provides an experimental proof of principle for future hybrid event reconstruction using both Cherenkov and scintillation signatures simultaneously.

Abstract
There is a critical need to deconvolute the heterogeneity displayed by the minor salivary glands of primary Sjögren’s syndrome (pSS) patients. This is challenging primarily because the disease etiology remains unknown. The hypothesis includes that initial events in the disease pathogenesis target the salivary glands, thereby triggering the development of focal infiltrates (≥50 mononuclear cells) and finally germinal center-like structures. However, the proportion of key mononuclear immune cells residing at these sites, in combination with the overall ratio of morphometric tissue atrophy and adipose infiltration within the minor salivary glands (MSG) parenchyma at distinct phases of inflammatory disease establishment and progression have not been quantified in detail. In this cross-sectional study, we intended to address this problem by stratifying 85 patients into mild (S1), moderate (S2), and severe (S3) stages using the Inflammatory severity index. We found that mild (<3%) and marked (≥3%) levels of atrophy were accompanied by the respective levels of adipose infiltration in the non-SS sicca controls (p <0.01), but not in pSS patients. The percentage of adipose infiltration significantly correlated with the age of patients (r = 0.458, p <0.0001) and controls (r = 0.515, p <0.0001). The CD4+ T helper cell incidence was reduced in the focal infiltrates of the MSG of S2 patients compared to S1 (p <0.01), and in S2 compared to S1 and S3 combined (p <0.05). CD20+ B cells increased from S1 to S3 (p <0.01) and S2 to S3 (p <0.01), meanwhile CD138+ plasma cells diminished in S3 patients compared to both S1 and S2 groups combined (p <0.01). The proportion of patients with anti-Ro/SSA+, anti-La/SSB+, and RF+ increased over the course of inflammatory disease progression and they were significantly more common in the S3 group relative to S1 (p <0.05). On the other hand, S2 patients measured a higher mean salivary flow relative to S1 and S3 patients combined (p <0.05). Our results demonstrate how the proposed Inflammatory severity index stratification revealed pathological cell and tissue-associated aberrations in the salivary component over the course of inflammatory progression, and their correlations to clinical outcomes. This could be directly transferred to the optimization of available diagnostic strategies applied for pSS patients.

Abstract
Psoriasis is a chronic immune-mediated skin disease accompanied by systemic inflammation and comorbidities. We analyzed peripheral blood mononuclear cells (PBMCs) in the search for immune signatures and biomarkers related to psoriasis severity and treatment effect. Thirty-two patients with psoriasis and 10 matched healthy controls were included. PBMCs were collected before and after initiation of anti-TNF, anti-IL-17 or anti-IL-12/23 treatment and analyzed utilizing 26-parameter mass cytometry. The number of circulating Th17, Th22, Th9, and cytotoxic T cells were increased in severe psoriasis. Intracellular pp38 and pERK in T helper cells were associated with disease severity. Differences between responders and nonresponders regarding cell composition and intracellular signaling were identifiable already at inclusion. Biological treatment induced memory cells, restored inhibitory PD-1 function of T cells, and reduced a potential pro-atherogenic profile in monocytes. In conclusion, these results indicate amelioration of systemic inflammation in psoriasis after biological treatment. Such broad immune profiling may enable prospective stratification of patients regarding future treatment response. Successful early intervention may lead to a healthier trajectory with favorable implications on later comorbidities.

Abstract
In the past decades, clinical and experimental evidence has demonstrated that psoriasis is an immune-mediated inflammatory disease of the skin that occurs in genetically susceptible individuals. Psoriasis also shows clear autoimmune pathomechanisms, but specific cellular targets for the onset and maintenance of psoriatic lesions were not established until 2014. Since then, four psoriasis autoantigens were discovered, namely cathelicidin LL-37, melanocytic ADAMTSL5, lipid antigen PLA2G4D and keratin 17. Autoreactive T cells against these autoantigens were found in a number of patients with moderate-to-severe plaque psoriasis. Moreover, the discovery of autoantibodies against LL-37 and ADAMTSL5 and their strong association with psoriatic arthritis (PsA) suggest a potential role of these autoantibodies in the pathogenesis of PsA. This review discusses the current studies on psoriatic autoantigens and the associated circulating autoantibodies and their mechanisms involved in the development and maintenance of psoriatic plaques. Recent autoimmune evidence fuelled the discussion on psoriasis as an autoimmune skin disorder and has the potential to develop new treatment strategies with protective and therapeutic antigen-targeted methods.

Abstract
Psoriasis is a T cell-mediated disease with autoimmune characteristics modulated by genetic susceptibility along with environmental triggers. Inflammatory pathways marked with excessive production of cytokines IL-12 and IL-23, drive differentiation of pathogenic T cell responses resulting in TNF and IL-17 production. These cytokines are an integral part of the TNF/IL-23/IL-17 axis, which is responsible for maintaining inflammation in psoriatic skin. Our improved understanding of the immunopathogenesis led to the development of biological drugs in the treatment of moderate-to-severe disease. Biologics have revolutionized the management of psoriasis, highlighting the central role of TNF/IL-23/IL-17 axis in the physiopathology of the disease. Still, psoriasis usually requires long-term treatment, aiming to fully remove psoriatic lesions without experiencing adverse events. In this review, we discuss the recent findings of all 27 available head-to-head trials investigating the efficacy and safety of systemic and biologic therapies in moderate-to-severe psoriasis vulgaris, as it is thought to provide more useful knowledge than placebo intervention alone. According to our evaluation, inhibitors that specifically target IL-23 or IL-17 are clinically more beneficial than inhibitors of IL-12/IL-23 and TNF. More informative results might be obtained by comparing these more efficient biological agents to each other. In addition, newer therapies for psoriasis using small-molecule drugs may represent important advances compared to well-established biologics as these are less expensive and orally administered.

Abstract
The transcription factor β-catenin is able to induce tolerogenic/anti-inflammatory features in different types of dendritic cells (DCs). Monocyte-derived dendritic cells (moDCs) have been widely used in dendritic cell-based cancer therapy, but so far with limited clinical efficacy. We wanted to investigate the hypothesis that aberrant differentiation or induction of dual pro- and anti-inflammatory features may be β-catenin dependent in moDCs. β-catenin was detectable in both immature and lipopolysaccharide (LPS)-stimulated DCs. The β-catenin inhibitor ICG-001 dose-dependently increased the pro-inflammatory signature cytokine IL-12p70 and decreased the anti-inflammatory signature molecule IL-10. The β-catenin activator 6-bromoindirubin-3′-oxime (6-BIO) dose-dependently increased total and nuclear β-catenin, and this was associated with decreased IL-12p70, increased IL-10, and reduced surface expression of activation markers, such as CD80 and CD86, and increased expression of inhibitory markers, such as PD-L1. 6-BIO and ICG-001 competed dose-dependently regarding these features. Genome-wide mRNA expression analyses further underscored the dual development of pro- and anti-inflammatory features of LPS-matured moDCs and suggest a role for β-catenin inhibition in production of more potent therapeutic moDCs.

Abstract
BACKGROUND AND PURPOSE Previous studies have reported conflicting results regarding possible anticipation in familial E200K Creutzfeldt-Jakob disease (fCJD). Our objective was to use a large database to assess the age of disease onset (AODO) in CJD. METHODS The study population included 477 CJD patients [266 with fCJD, 145 with sporadic CJD (sCJD) and 66 patients of Libyan origin but negative family history] from the Israeli registry of CJD conducted since 1954. In all patients, AODO in relatives and family trees was documented. Comparison of AODO was done using a paired t test and regression using Pearson correlation for birth and year of onset. RESULTS The initial analysis in 52/73 families in which more than one generation was affected revealed an AODO of 63.30 ± 9.44 in the first generation compared to 56.96 ± 8.99 in the second generation (P < 0.001). However, inspection of individual AODO values plotted by year of birth showed a clear rhomboid methodological artifact generated by missing data of many young onset CJD patients who died before the database began to function in 1954 and of many late onset CJD patients missing at the present time since they will only develop the disease in the future. The 'generation' effect completely disappears if analysis is performed by year of disease onset or for the periods in which complete data are available. CONCLUSIONS In this very large dataset, true anticipation in fCJD patients was not detected. It is plausible that previous reports supporting the presence of anticipation are biased by a rhomboid-shaped data availability artifact.

Abstract
Type 1 diabetes (T1D) is largely considered an autoimmune disease leading to the destruction of insulin-producing pancreatic β cells. Further, patients with T1D have 3-4-fold increased risk of developing micro- and macrovascular complications. However, the contribution of immune-related factors contributing to these diabetes complications are poorly understood. Individuals with long-term T1D who do not progress to vascular complications offer a great potential to evaluate end-organ protection. The aim of the present study was to investigate the association of inflammatory protein levels with vascular complications (retinopathy, nephropathy, cardiovascular disease) in individuals with long-term T1D compared to individuals who rapidly progressed to complications. We studied a panel of inflammatory markers in plasma of patients with long-term T1D with (n = 81 and 26) and without (n = 313 and 25) vascular complications from two cross-sectional Scandinavian cohorts (PROLONG and DIALONG) using Luminex technology. A subset of PROLONG individuals (n = 61) was screened for circulating immune cells using multicolor flow cytometry. We found that elevated plasma levels of soluble interleukin-2 receptor alpha (sIL-2R) were positively associated with the complication phenotype. Risk carriers of polymorphisms in the IL2RA and PTPN2 gene region had elevated plasma levels of sIL-2R. In addition, cell surface marker analysis revealed a shift from naïve to effector T cells in T1D individuals with vascular complications as compared to those without. In contrast, no difference between the groups was observed either in IL-2R cell surface expression or in regulatory T cell population size. In conclusion, our data indicates that IL2RA and PTPN2 gene variants might increase the risk of developing vascular complications in people with T1D, by affecting sIL-2R plasma levels and potentially lowering T cell responsiveness. Thus, elevated sIL-2R plasma levels may serve as a biomarker in monitoring the risk for developing diabetic complications and thereby improve patient care.

Abstract
Monocyte-derived dendritic cells (moDC) are an important scientific and clinical source of functional dendritic cells (DC). However, the optimization of the generation process has to date mainly been limited to the variation of soluble factors. In this study, we investigated the impact of the cell culture dish surface on phenotype and cytokine profile. We compared a standard cell culture dish to a non-adherent culture dish for two immunogenic maturation conditions, two tolerogenic conditions, and an unstimulated control. Phenotype, cytokine profile and T cell stimulatory capacity were determined after a 3-day culture. Light microscopy revealed an increase in homotypic cluster formation correlated with the use of non-adherent surfaces, which could be reduced by using blocking antibodies against CD18. All surface markers analyzed showed moderate to strong differences depending on the culture dish surface, including significantly decreased expression of key maturation markers such as CD80, CD86, and CCR7 as well as PD-L1 on cells stimulated with the Jonuleit cytokine cocktail cultured on a non-adherent surface. Significant differences in the secretion of many cytokines were observed, especially for cells stimulated with LPS, with over 10-fold decreased secretion of IL-10, IL12-p40, and TNF-α from the cells cultured on the non-adherent surface. All immunogenic moDC populations showed similar capacity to induce antigen-specific T cells. These results provide evidence that the DC phenotype depends on the surface used during moDC generation. This has important implications for the optimization of DC-based immunotherapy development and underlines that the local surrounding can interfere with the final DC population beyond the soluble factors.

Abstract
Abstract
Background: Dendritic cells (DCs) are the most potent antigen-presenting cells of the immune system and are consequently exploited in cancer immunotherapy in order to present tumor-associated antigens to lymphocytes. The ability of tumor cells to induce tolerogenic DCs and avoid the immune system challenges DC-based immunotherapies. Utilizing buffycoats of healthy blood donors we have investigated the activation of gene expression programs conventionally associated with either pro- or anti-inflammatory features of monocyte-derived DCs.
Methodology: Following isolation of monocytes from buffycoats, various culture conditions were tested to generate immature DCs and to mature and activate them in vitro. Genome-wide gene expression, secretion of cytokines and tryptophan metabolites, surface expression of maturation and activation markers, and functional abilities were analyzed. Specifically, beta-catenin and indoleamine 2,3-dioxigenase 1 (IDO-1) activation were examined using both agonists and inhibitors of those pathways.
Results: A considerable variability among buffycoats of different healthy blood donors was observed regarding DC yield and cytokine secretion. Induction time to generate immature DCs with interleukin-4 and granulocyte-macrophage colony-stimulating factor affected DC differentiation. Several maturation conditions induced strong IDO-1 expression. Activation of beta-catenin during DC maturation induced anti-inflammatory features that could be competed by adding beta-catenin inhibitors during cultivation of the cells. Pro- and anti-inflammatory features often co-existed in mature DCs.
Conclusions: Beta-catenin and IDO-1 activation are prevalent according to different conditions of monocyte-derived DC maturation and associated with anti-inflammatory features. Both pathways can be inhibited by specific antagonists. More robust pro-inflammatory DC generation is desirable for more effective cancer immunotherapy.

Abstract
Primary Sjögren's syndrome (pSS) is associated with polymorphisms and mRNA expression profiles that are indicative of an exaggerated innate and type I IFN immune response. Excessive activation potential of signaling pathways may play a role in this profile, but the intracellular signaling profile of the disease is not well characterized. To gain insights into potentially dysfunctional intracellular signaling profiles of pSS patients we conducted an exploratory analysis of MAPK/ERK and JAK/STAT signaling networks in peripheral blood mononuclear cells (PBMC) from 25 female pSS patients and 25 female age-matched healthy donors using phospho-specific flow cytometry. We analyzed unstimulated samples, as well as samples during a 4 h time period following activation of Toll-like receptor (TLR) 7 and 9. Expression levels of MxA, IFI44, OAS1, GBP1, and GBP2 in PBMC were analyzed by real-time PCR. Cytokine levels in plasma were determined using a 25-plex Luminex-assay. Principal component analysis (PCA) showed that basal phosphorylation profiles could be used to differentiate pSS patients from healthy donor samples by stronger intracellular signaling pathway activation in NK and T cells relative to B cells. Stimulation of PBMC with TLR7 and -9 ligands showed significant differences in the phosphorylation profiles between samples from pSS patients and healthy donors. Including clinical parameters such as extraglandular manifestations (EGM), we observed stronger responses of NF-κB and STAT3 S727 in B cells from EGM-negative patients compared to EGM-positive patients and healthy controls. Plasma cytokine levels were correlated to the basal phosphorylation levels in these patients. In addition, 70% of the patients had a positive IFN score. These patients differed from the IFN score negative patients regarding their phosphorylation profiles and their plasma cytokine levels. In conclusion, we here report increased signaling potentials in peripheral B cells of pSS patients in response to TLR7 and -9 stimulation through STAT3 S727 and NF-κB that correlate with a type I IFN signature. Induction of these pathways could contribute to the generation of a type I IFN signature in pSS. Patients displaying elevated potentiation of STAT3 S727 and NF-κB signaling could therefore benefit from therapies targeting these pathways.

Abstract
Psoriasis is an immune-mediated disease where the IL-23/Th17 axis as well as TNF comprise main targets of biological therapy. Immune profiling has so far not been embraced as a clinical tool. We aimed to investigate relationships between individual serum cytokine levels in 40 psoriasis patients before and after receiving biological therapy and Psoriasis Area and Severity Index (PASI) and Dermatological Life Quality Index (DLQI). Serum concentration of 25 cytokines was determined by Luminex technology. Mean PASI and DLQI decreased by 71% and 65%, respectively. Increase of IL-2 positively correlated with improvement of PASI and DLQI. Moreover, increase of IL-5, IL-10, IL-12, IL-22 and GM-CSF correlated with treatment effect. Notably, logistic regression revealed four times higher risk of having severe psoriasis when IL-17A increased by 1 pg/mL (OR: 4.06, P < 0.05). Selected serum cytokines might constitute useful biomarkers for monitoring disease activity and optimizing therapeutic strategies in psoriasis patients.

Abstract
Numerous trials using dendritic cell (DC)-based vaccinations for the treatment of cancer are being carried out. However, an improvement of the quality of DC used is highly warranted. We here generated human monocyte-derived dendritic cells using a 3 day protocol and stimulated the cells using a combination of OK432 (Picibanil), TLR7/8 ligand CL097, and reduced amounts of prostaglandin (PG)E2. We analyzed phenotype, migratory, and T-cell stimulatory capacity compared to a cytokine cocktail consisting of IL-1β, IL-6, TNF, and PGE2. The OK432 cocktail stimulated cells had a similar mature phenotype with upregulated co-stimulatory molecules, HLA-DR and CCR7 as the cytokine cocktail-matured cells and a similar cytokine profile except increased amounts of IL-12p70. Chemotaxis towards CCL19 was reduced compared to the cytokine cocktail, but increased compared to OK432 alone. The T-cell stimulatory capacity was similar to the cytokine cocktail stimulated cells. In conclusion, the OK432 cocktail has the advantage of inducing IL-12p70 production without impairing phenotype or T-cell stimulatory capacity of the cells and might, therefore, be an advantageous alternative to be used in DC-based immunotherapy.

Abstract
BACKGROUND Psoriasis vulgaris is a chronic, inflammatory skin disease characterized by a dysregulated immune response and it is associated with substantial systemic comorbidities. Biological drugs such as tumour necrosis factor (TNF)-α inhibitors can ameliorate the disease but are expensive. Biosimilar drugs have the same amino-acid sequence as the originator, but differences in manufacturing can affect biological activity, efficacy and tolerability. OBJECTIVES To explore potential differences in intracellular phosphorylation of signalling molecules in peripheral blood cells from patients with psoriasis treated with the TNF-α inhibitor infliximab compared with healthy controls, and to investigate if the phosphorylation pattern was influenced by switching from the originator infliximab to the biosimilar CT-P13. METHODS By flow cytometry, we measured phosphorylation of nuclear factor kappa B, extracellular signal-regulated kinase 1/2, p38 mitogen-activated protein kinase and signal transducer and activator of transcription 3, before and after TNF-α stimulation in monocytes and T, B, natural killer and CD3+ CD56+ cells from 25 patients with psoriasis treated with infliximab and 19 healthy controls. RESULTS At inclusion, phosphorylation levels of peripheral blood mononuclear cells (PBMCs) were increased in patients with psoriasis compared with healthy controls, even though clinical remission had already been achieved. Phosphorylation levels declined in patients on both originator infliximab and biosimilar during continued treatment. No significant differences were detected between the two medications after 12 months. CONCLUSIONS Patients with psoriasis on infliximab have higher activation levels of PBMCs than do healthy controls, possibly reflecting systemic inflammation. Switching from the originator infliximab to biosimilar CT-P13 did not affect phosphorylation levels or clinical parameters, suggesting that CT-P13 is a noninferior treatment alternative to the originator infliximab.

Abstract
Primary Sjögren's syndrome (pSS) is a complex systemic autoimmune disease with heterogeneous disease manifestations. Genetic predisposition, hormonal and environmental factors are all thought to contribute to disease etiology and pathogenesis. A better understanding of the disease pathogenesis is required in order to establish new targeted therapies. We analysed MAPK/ERK and JAK/STAT signalling networks in peripheral blood mononuclear cells (PBMCs) upon stimulation with interferon alpha 2b (IFN‐α2b) by flow cytometry to define potentially dysfunctional intracellular signalling pathways involved in disease pathogenesis. Cells derived from pSS patients displayed small but significant increases in basal phosphorylation levels of numerous signalling proteins compared to cells from healthy donors. The phosphorylation profiles following stimulation with IFNα2b differed significantly between pSS patients and healthy donors, especially regarding STAT1 Y701. PCA further grouped patients according to clinical characteristics. Type I IFN induced gene expression was found to negatively correlate with the IFN‐α2b induced phosphorylation of STAT3 S727 in T cells and positively with pSTAT1 Y701 in B cells. Increases in pSTAT1 Y701 were associated with the presence of autoantibodies. Our results indicate involvement of both STAT3 S727 and STAT1 Y701 pathways in pSS patients. Therapies targeting these pathways might therefore be beneficial for certain subgroups of patients.

Abstract
Cellular therapies with CD4+ T regulatory cells (Tregs) hold promise of efficacious treatment for the variety of autoimmune and allergic diseases as well as posttransplant complications. Nevertheless, current manufacturing of Tregs as a cellular medicinal product varies between different laboratories, which in turn hampers precise comparisons of the results between the studies performed. While the number of clinical trials testing Tregs is already substantial, it seems to be crucial to provide some standardized characteristics of Treg products in order to minimize the problem. We have previously developed reporting guidelines called minimum information about tolerogenic antigen-presenting cells, which allows the comparison between different preparations of tolerance-inducing antigen-presenting cells. Having this experience, here we describe another minimum information about Tregs (MITREG). It is important to note that MITREG does not dictate how investigators should generate or characterize Tregs, but it does require investigators to report their Treg data in a consistent and transparent manner. We hope this will, therefore, be a useful tool facilitating standardized reporting on the manufacturing of Tregs, either for research purposes or for clinical application. This way MITREG might also be an important step toward more standardized and reproducible testing of the Tregs preparations in clinical applications.

Abstract
Borexino is a liquid scintillator detector sited underground in the Laboratori Nazionali del Gran Sasso (Italy). Its physics program, until the end of this year, is focussed on the study of solar neutrinos, in particular from the Beryllium, pp, pep and CNO fusion reactions. Knowing the reaction chains in the sun provides insights towards physics disciplines such as astrophysics (star physics, star formation, etc.), astroparticle and particle physics. Phase II started in 2011 and its aim is to improve the phase I results, in particular the measurements of the neutrino fluxes from the pep and CNO processes. By the end of this year, data taking from the sun will be over and a new project is scheduled to launch: Short distance Oscillation with boreXino (SOX), which uses a Cerium source for neutrinos (100÷150 kCi of activity) and aims to confirm or rule out the presence of sterile neutrinos. This particle is hypothesised to justify the reactor, Gallium and LSND anomalies found and can reject extensions to the standard model. The work presented is a summary of the solar neutrino results achieved so far, which lead not only to a precise study of the processes in the sun, but also to more Standard Model oriented measurements (such as the stability of the charge, i.e. the life time of the electron). Furthermore, the perspectives of the SOX program are discussed showing the experiment sensitivity to a fourth neutrino state covering almost entirely 3σ of the preferred region of the anomalous neutrino experiments, and additional applications of the detector such as the study of geo-neutrinos.

Abstract
An accurate dissection of peripheral blood enumeration is lacking in primary Sjögren's syndrome (pSS). The purpose of this study was to quantify different leucocyte populations in peripheral blood of patients with pSS. Numbers of specific leucocyte subsets were determined in 86 pSS patients and 74 healthy donors quantifying 21 distinct subtypes by flow cytometry. Subgroups of pSS patients were stratified based on presence of extraglandular manifestations (EGMs) and SSA/SSB autoantibodies. Overall, pSS patients manifested decreased lymphocyte subpopulations compared to healthy donors. Such decreases were more pronounced in SSA/SSB positive patients and patients with EGM. Granulocyte and monocyte subpopulations were increased in pSS patients compared to healthy donors, with the greatest increases in SSA/SSB positive patients. Unsupervised hierarchal clustering based on cell quantities was used to further subgroup the pSS patients into four clusters. One of the clusters characterized by higher concentrations of NKT cells, CD56hi NK cells, CD20+ CD38- B cells and CD8+ CD38- T cells was associated with weaker clinical symptoms than the other clusters, possibly marking a milder disease phenotype. In conclusion, our analyses indicate significant alterations in the cellular profiles of peripheral blood leucocytes in patients with pSS and may help to stratify the patients according to disease severity.

Abstract
Toll-like receptors (TLRs) are pattern recognition receptors important for the detection of pathogen-associated molecular patterns. They are localized on cellular membranes, on either the cell surface or the endosomes. Primary Sjögren's syndrome (pSS) is a systemic rheumatic autoimmune disease characterized by lymphocytic infiltrations in exocrine glands resulting in dryness in eyes and mouth. In a majority of patients, autoantibodies against Ro/SSA and/or La/SSB are present. Here we analysed mRNA levels of TLR1-10 and protein expression levels of most of them in human peripheral blood mononuclear cells from 20 patients with pSS and 20 healthy controls. Patients with pSS showed significantly higher mRNA levels of TLR8 than controls, while transcript levels of TLR9 were significantly lower. At the protein level, patients with pSS expressed significantly less TLR5 and significantly more TLR7 compared with healthy controls. TLR7 and 8 are encoded by genes localized on the X chromosome, which is especially interesting regarding the gender imbalance of pSS. The differential expression of various TLR in PBMC of patients with pSS might contribute to an altered recognition of nucleic acids, eventually resulting in the development of autoimmune disease.

Abstract
Cellular therapies with tolerogenic antigen-presenting cells (tolAPC) show great promise for the treatment of autoimmune diseases and for the prevention of destructive immune responses after transplantation. The methodologies for generating tolAPC vary greatly between different laboratories, making it difficult to compare data from different studies; thus constituting a major hurdle for the development of standardised tolAPC therapeutic products. Here we describe an initiative by members of the tolAPC field to generate a minimum information model for tolAPC (MITAP), providing a reporting framework that will make differences and similarities between tolAPC products transparent. In this way, MITAP constitutes a first but important step towards the production of standardised and reproducible tolAPC for clinical application.

Abstract
Phosphoflow cytometry is increasingly being used as a tool for the discovery of biomarkers used in the treatment and monitoring of disease and therapy. The ability to measure numerous phospho-protein targets simultaneously at a single cell level accurately and rapidly provides significant advantages over other methods. We here discuss important considerations required to successfully implement these methods. Three different blood collection tubes (lithium-heparin tubes, CPT with sodium citrate and CPT with sodium heparin) were evaluated, with PBMC isolated through lithium-heparin tubes/lymphoprep displaying reduced basal and increased stimulation induced phosphorylation compared to the other two methods. Further, we provide a protocol outlining an 8 color assay developed for the study of intracellular signaling in peripheral blood mononuclear cells. The assay allows for the quantitative measurement of the phospho-proteins ERK1/2, NF-κB p65, Stat1 (Y701), Stat1 (S727), Stat3 (Y705), Stat3 (S727), Stat4 (Y693), p38 and Stat5 (Y694), as well as the identification of T cells, B cells, natural killer cells and monocytes. The assay additionally incorporates fluorescent cell barcoding, reducing assay costs and increasing throughput while increasing data robustness. Inter-assay precision was assessed over a month long period for all experimental variables (phospho-protein measured, cell type and stimulant). Coefficient of variations (CVs) calculated from process triplicates of normalized median fluorescence intensity (MFI) of the phospho-proteins displayed median CVs under 10% when grouped according to cell type, stimulation agent and phospho-protein measured, while the CV for each triplicate did not exceed 20%.

Abstract
BACKGROUND Creutzfeldt-Jakob disease (CJD) is the most common prion disease in humans. The clinical diagnosis of CJD is supported by a combination of electroencephalogram, MRI, and the presence in the CSF of biomarkers. CSF tau is a marker for neuronal damage and tangle pathology, and is correlated with cognitive status in Alzheimer's disease (AD). OBJECTIVES The aim of this study was to test whether tau levels in the CSF also correlate with the degree of the neurological deficit and cognitive decline in patients with CJD as reflected by various clinical scales that assess disease severity and cognitive performance. METHODS Consecutive patients with familial CJD (fCJD) were examined by a neurologist who performed several tests including minimental status examination (MMSE), frontal assessment battery (FAB), NIH stroke scale (NIHSS), CJD neurological scale (CJD-NS), and the expanded disability status scale (EDSS). CSF tau was tested as part of the workout, and the correlation was tested using Pearson correlation. RESULTS Fifty-two patients with fCJD were recruited to the study (35 males, mean age 59.4 ± 5.7, range 48-75 years). A significant negative correlation was found between CSF tau levels and the cognitive performance of the patients as reflected by their MMSE and FAB scores. In addition, a significant positive correlation was found between tau levels and the clinical disease severity scales of CJD-NS, NIHSS, and EDSS. CONCLUSION The correlation between tau levels and the disease severity and degree of cognitive decline in patients with fCJD suggests that tau can be a biomarker reflecting the extent of neuronal damage.
