Abstract
The overexpression of sialic acids on glycans, called hypersialylation, is a common alteration found in cancer cells. Sialylated glycans can enhance immune evasion by interacting with sialic acid-binding immunoglobulin-like lectin (Siglec) receptors on tumor-infiltrating immune cells. Here, we investigated the effect of sialylated glycans and their interaction with Siglec receptors on myeloid-derived suppressor cells (MDSCs). We found that MDSCs derived from the blood of lung cancer patients and tumor-bearing mice strongly express inhibitory Siglec receptors and are highly sialylated. In murine cancer models of emergency myelopoiesis, Siglec-E knockout in myeloid cells resulted in prolonged survival and increased tumor infiltration of activated T cells. Targeting suppressive myeloid cells by blocking Siglec receptors or desialylation strongly reduced their suppressive potential. We further identified CCL2 as a mediator involved in T-cell suppression upon interaction between sialoglycans and Siglec receptors on MDSCs. Our results demonstrated that sialylated glycans inhibit anticancer immunity by modulating CCL2 expression.

Abstract
The lack of suitable models currently hampers our understanding of how the tumor microenvironment responds to immunotherapy treatment. Here, we present a protocol for ex vivo culture of patient-derived tumor fragments (PDTFs). We describe the steps for tumor collection, generation and cryopreservation of PDTFs, and their subsequent thawing. We detail culture of PDTFs and their preparation for analysis. This protocol preserves the tumor microenvironment's composition, architecture, and cellular interactions, which can be perturbed by ex vivo treatment. For complete details on the use and execution of this protocol, please refer to Voabil et al. (2021).1.

Abstract
Introduction Immunotherapies have improved the prognosis of many cancer patients including patients with advanced melanoma. Immune checkpoint receptors including CTLA-4 and PD-1 have been established as main therapeutic targets for immunotherapy of melanoma. Although monotherapy is effective in melanoma patients, a dual therapy approach has been shown to be most effective. Dual checkpoint blockade, however, increases substantially the risk for immune-related adverse events (irAEs). Methods In this study, we characterized peripheral immune cell subsets in patients with anti-PD-1 monotherapy and with dual immune receptors blockade targeting PD-1 and CTLA-4. Results We found differences in peripheral T cells between patients who developed severe immune-related side effects and patients with mild irAEs. We identified several mainly changes in CD8+ T cell subsets in patients with severe irAE under dual PD-1 and CTLA-4 blockade. Discussion This work suggests that peripheral immune cell dynamics could be associated with severe immune-related side effects in patients receiving immune checkpoint inhibitors. These changes could be used as future biomarkers in early diagnosis of irAEs.

Abstract
Tumor-specific T cells are frequently exhausted by chronic antigenic stimulation. We here report on a human antigen-specific ex vivo model to explore new therapeutic options for T cell immunotherapies. T cells generated with this model resemble tumor-infiltrating exhausted T cells on a phenotypic and transcriptional level. Using a targeted pooled CRISPR-Cas9 screen and individual gene knockout validation experiments, we uncover sorting nexin-9 (SNX9) as a mediator of T cell exhaustion. Upon TCR/CD28 stimulation, deletion of SNX9 in CD8 T cells decreases PLCγ1, Ca2+, and NFATc2-mediated T cell signaling and reduces expression of NR4A1/3 and TOX. SNX9 knockout enhances memory differentiation and IFNγ secretion of adoptively transferred T cells and results in improved anti-tumor efficacy of human chimeric antigen receptor T cells in vivo. Our findings highlight that targeting SNX9 is a strategy to prevent T cell exhaustion and enhance anti-tumor immunity.

Abstract
BACKGROUND Next-generation cancer immunotherapies are designed to broaden the therapeutic repertoire by targeting new immune checkpoints including lymphocyte-activation gene 3 (LAG-3) and T cell immunoglobulin and mucin-domain containing-3 (TIM-3). Yet, the molecular and cellular mechanisms by which either receptor functions to mediate its inhibitory effects are still poorly understood. Similarly, little is known on the differential effects of dual, compared with single, checkpoint inhibition. METHODS We here performed in-depth characterization, including multicolor flow cytometry, single cell RNA sequencing and multiplex supernatant analysis, using tumor single cell suspensions from patients with cancer treated ex vivo with novel bispecific antibodies targeting programmed cell death protein 1 (PD-1) and TIM-3 (PD1-TIM3), PD-1 and LAG-3 (PD1-LAG3), or with anti-PD-1. RESULTS We identified patient samples which were responsive to PD1-TIM3, PD1-LAG3 or anti-PD-1 using an in vitro approach, validated by the analysis of 659 soluble proteins and enrichment for an anti-PD-1 responder signature. We found increased abundance of an activated (HLA-DR+CD25+GranzymeB+) CD8+ T cell subset and of proliferating CD8+ T cells, in response to bispecific antibody or anti-PD-1 treatment. Bispecific antibodies, but not anti-PD-1, significantly increased the abundance of a proliferating natural killer cell subset, which exhibited enrichment for a tissue-residency signature. Key phenotypic and transcriptional changes occurred in a PD-1+CXCL13+CD4+ T cell subset, in response to all treatments, including increased interleukin-17 secretion and signaling toward plasma cells. Interestingly, LAG-3 protein upregulation was detected as a unique pharmacodynamic effect mediated by PD1-LAG3, but not by PD1-TIM3 or anti-PD-1. CONCLUSIONS Our in vitro system reliably assessed responses to bispecific antibodies co-targeting PD-1 together with LAG-3 or TIM-3 using patients' tumor infiltrating immune cells and revealed transcriptional and phenotypic imprinting by bispecific antibody formats currently tested in early clinical trials.

Abstract
Inhibitors of the PD-1-PD-L1 axis have been approved as therapy for many human cancers. In spite of the evidence for their widespread clinical activity, little is known about the immunological alterations that occur in human cancer tissue after PD-1 blockade. We developed and employed a patient-derived tumor fragment platform to dissect the early immunological response of human tumor tissue to ex vivo PD-1 blockade. We observed that the capacity of immune cells to be reactivated ex vivo was predictive of clinical response, and perturbation analyses identified tumor-resident T cells as a key component of this immunological response. In addition, through combined analysis of baseline properties and immune response capacity, we identified a new subgroup of infiltrated tumors that lacks the capacity to respond to PD-1 blockade. Finally, the baseline presence of tertiary lymphoid structures and their components correlated with the capacity of cancers to undergo intratumoral immune cell reactivation.

Abstract
Background Cancer immunotherapy elicits functional activation and changes in immune cell distribution in cancer. Tumour heterogeneity is a reason for treatment failure but is difficult to capture in experimental settings. This proof-of-principle study describes the integrated functional and digital spatial profiling platform iPROFILER to capture in-situ immune activation patterns with high precision. Materials and methods iPROFILER combines an algorithm-based image analysis approach for spatial profiling with functional analyses of patient-derived tumour fragments (PDTFs). This study utilized a folate receptor 1 (FOLR1)xCD3 bispecific antibody in dual-affinity re-targeting (DART) format as a tool for inducing T-cell responses in patient tumour samples, and an in-depth investigation of the immune perturbations induced in the tumour microenvironment was performed. Results Ex-vivo DART stimulation induces upregulation of multiple activation markers in CD4+ and CD8+ T-cell populations and secretion of pro-inflammatory cytokines in FOLR1-positive tumour specimens. This response was reduced or absent in tissue samples that did not express FOLR1. Immunological responses were driven by a strong induction of interferon gamma (IFNγ) and IFNγ-induced chemokines suggestive of activation of cytotoxic or Th1-like T cells. Ex-vivo DART treatment led to a numerical increase in effector T cells and an upregulation of immune activation markers in the tumour microenvironment as captured by digital image analysis. Analysis of immune activation in tumour and stromal regions further supported the potential of the platform to measure local differences in cell-type-specific activation patterns. Conclusions iPROFILER effectively combines functional and spatial readouts to investigate immune responses ex vivo in human tumour samples. Patient-derived tumour fragments preserve tumour composition and architecture ex vivo. Combined functional and spatial profiling captures in-situ immune activation. Ex-vivo DART induces pro-inflammatory immune responses in human tumours. Tumour/stroma analysis reveals local differences in specific activation patterns.

Abstract
Reprogramming tumor infiltrating myeloid cells to elicit pro-inflammatory responses is an exciting therapeutic maneouver to improve anti-tumor responses. We recently demonstrated that a distinct microtubule-targeting drug, plinabulin—a clinical-stage novel agent—modulates dendritic cell maturation and enhances anti-tumor immunity. Here, we investigated the effects of plinabulin on macrophage polarization in vitro and in vivo. Plinabulin monotherapy induced significant tumor growth inhibition in mice bearing subcutaneous MC38 colon cancer. Importantly, the regressing tumors were characterized by an increase in M1-like/M2-like tumor-associated macrophages (TAM) ratio. The efficacy of plinabulin remained unaltered in T cell-deficient Rag2−/− mice, suggesting an important role of macrophages in driving the drug's anti-tumor effect. Exposure of murine and healthy human macrophages to plinabulin induced polarization toward the M1 phenotype, including increased expression of co-stimulatory molecules CD80, CD86 and pro-inflammatory cytokines IL-1β, IL-6, and IL-12. M2-associated immunosuppressive cytokines IL-10 and IL-4 were reduced. This pro-inflammatory M1-like skewing of TAMs in response to plinabulin was dependent on the JNK pathway. Functionally, plinabulin-polarized human M1 macrophages directly killed HuT 78 tumor cells in vitro. Importantly, plinabulin induced a functional M1-like polarization of tumor infiltrating macrophages in murine tumors as well as in tumor samples from ovarian cancer patients, by preferentially triggering M1 proliferation. Our study uncovers a novel immunomodulatory effect of plinabulin in directly triggering M1 polarization and proliferation as well as promoting TAM anti-tumoral effector functions.

Abstract
BACKGROUND The costimulatory receptor 4-1BB (CD137, TNFRSF9) plays an important role in sustaining effective T cell immune responses and is investigated as target for cancer therapy. Systemic 4-1BB directed therapies elicit toxicity or low efficacy, which significantly hampered advancement of 4-1BB-based immunotherapy. Therefore, targeted delivery of 4-1BB agonist to the tumor side is needed for eliciting antitumor efficacy while avoiding systemic toxicity. METHODS We analyzed the immunostimulatory properties of a fibroblast activation protein (FAP)-targeted 4-1BB agonist (FAP-4-1BBL) by assessing tumor-infiltrating lymphocytes' (TIL) activity from patients with non-small cell lung cancer and epithelial ovarian cancer. RESULTS Combination treatment with FAP-4-1BBL and T cell receptor stimulation by either anti-CD3 or T cell bispecific antibodies significantly enhanced TIL activation and effector functions, including T cell proliferation, secretion of proinflammatory cytokines and cytotoxicity. Notably, costimulation with FAP-4-1BBL led to de novo secretion of interleukin (IL)-13. This was associated with cytokine-mediated tumor cell apoptosis, which was partially dependent on IL-13 alpha 1/2 receptors and STAT6 phosphorylation. CONCLUSIONS Our study provides mechanistic insights into T cell stimulation induced by FAP-4-1BBL in primary human tumors and supports the investigation of FAP-4-1BBL compound in early clinical trials.

Abstract
Natural killer (NK) cells are critically involved in anti-tumor immunity by targeting tumor cells. In this study, we show that intratumoral NK cells from NSCLC patients expressed elevated levels of the immune checkpoint receptor PD-1 on their cell surface. In contrast to the expression of activating receptors, PD-1+ NK cells co-expressed more inhibitory receptors compared to PD-1- NK cells. Intratumoral NK cells were less functional compared to peripheral NK cells, and this dysfunction correlated with PD-1 expression. Tumor cells expressing PD-L1 inhibited the functionality of PD-1+ NK cells in ex vivo models and induced PD-1 clustering at the immunological synapse between NK cells and tumor cells. Notably, treatment with PD-1 blockade was able to reverse PD-L1-mediated inhibition of PD-1+ NK cells. Our findings highlight the therapeutic potential of PD-1+ NK cells in immune checkpoint blockade and could guide the development of NK cell-stimulating agents in combination with PD-1 blockade.

Abstract
BACKGROUND/AIM Carbonic anhydrase 12 (CA12) is a membrane-associated enzyme that is highly expressed on many human cancers. It is a poor prognostic marker and hence an attractive target for cancer therapy. This study aimed to develop a humanized CA12-antibody with anti-cancer activity. MATERIALS AND METHODS Antibody libraries were constructed and screened by the Retrocyte display®. Antibody binding and blocking properties were determined by ELISA, flow cytometry and enzymatic activity assays. Spheroid viability was determined by Cell-Titer-Fluor assay. RESULTS We developed a novel humanized CA12-specific antibody, 4AG4, which recognized CA12 as an antigen and blocked CA12 enzymatic activity. Our humanized CA12-antibody significantly inhibited spheroid growth of lung adenocarcinoma A549-cells in vitro by blocking CA12 enzymatic activity. Similar anti-tumor effects were recapitulated with CA12-gene knockout of A549-cells. CONCLUSION Our newly identified humanized CA12-antibody with anti-cancer activity, represents a new tool for the treatment of CA12-positive tumors.

Abstract
Abstract
The M2 phenotype is dominant in tumor associated macrophages (TAMs) and correlates with poor prognosis. As M1 polarized macrophages possess anti-tumor functions, in vivo reprogramming of macrophages is a promising strategy for cancer treatment. We recently demonstrated that microtubule destabilizing chemotherapeutic agents such as plinabulin induce potent dendritic cell maturation and thereby augment anti-tumor immune responses; yet the effects of plinabulin on macrophage polarization remain unknown. Here we demonstrate that plinabulin, which is currently being investigated for both its anti-tumor effect and prevention of chemotherapy-induced neutropenia in phase II/III clinical trials,induces M1 polarization of ex vivo cultured human monocyte-derived M2 macrophages. This was characterized by a reduction in the cell surface expression of M2 markers CD163 and CD206 and an increase in the expression of co-stimulatory M1 markers CD80 and CD86. Phenotypically, plinabulin-polarized human M1 macrophages secreted increasing levels of iNOS and inflammatory cytokines IL-1β, IL-6 and IL-12 while IL-10 and IL-4 secretion decreased. This suggests a functional skewing from immunosuppressive M2 to pro-inflammatory M1 macrophages upon exposure to plinabulin. Similarly, plinabulin induced the M1 polarization of murine FACS sorted F4/80+ intratumoral M2-TAMs, characterized by increased CD80 and decreased CD206 expression. Moreover, systemic treatment (i.p.) of tumor bearing mice with plinabulin led to a significant reduction in the number of tumor-infiltrating TAMs with a concomitant M1 polarization of the remaining TAMs. Indeed, plinabulin treatment of mice bearing subcutaneous MC38 colon cancer or orthotopic EMT6 breast cancer tumors significantly delayed tumor growth. This efficacy of plinabulin remained unaltered in Rag2-/- mice lacking T cells, suggesting that macrophages are required for its anti-tumor activity. These results identify targeting of TAMs by plinabulin as a promising therapeutic strategy. Testing of plinabulin in combination with other macrophage targeting drugs are currently being explored to investigate the dual effect in reprogramming the tumor immune microenvironment.

Abstract
BACKGROUND Treatment with a combination of PD-1 and CTLA-4 targeted checkpoint inhibition has improved outcome of melanoma patients and led to durable remissions but is also associated with significant toxicities. Endocrinopathies such as thyroiditis and hypophysitis are often seen, but other, rarer disturbances have also been described. Endocrinopathies affecting the parathyroid gland are rarely reported and no clear pathomechanism has been proposed. CASE PRESENTATION Here, we report a case of severe hypocalcemia due to an antibody-mediated hypoparathyroidism as an immune-related adverse event (irAE) in a patient who was treated with the anti-PD-1 antibody nivolumab and anti-CTLA-4 antibody ipilimumab. Hypocalcemia was rapidly corrected by substitution, but the endogenous serum parathyroid hormone (PTH) remained low. The patient demonstrated a rapid and profound tumor response to the combination immune checkpoint blockade, but developed a severe colitis that required high-dose intravenous corticosteroid and anti-TNFα therapy. During this strong immunosuppression the PTH level normalized and the calcium levels were stable without substitution. However, during tapering of immunosuppressants, the PTH and calcium levels decreased again to a level requiring calcium substitution. CONCLUSION Our report demonstrates a rare endocrinopathy as a complication of combined PD-1 and CTLA-4 blockade. In addition, it provides evidence from the course of the disease that inflammation within the parathyroid gland is involved in the mechanism.

Abstract
PURPOSE PD-(L)1-blocking antibodies have clinical activity in metastatic non-small cell lung cancer (NSCLC) and mediate durable tumor remissions. However, the majority of patients are resistant to PD-(L)1 blockade. Understanding mechanisms of primary resistance may allow prediction of clinical response and identification of new targetable pathways. EXPERIMENTAL DESIGN Peripheral blood mononuclear cells were collected from 35 patients with NSCLC receiving nivolumab monotherapy. Cellular changes, cytokine levels, gene expression, and polymorphisms were compared between responders and nonresponders to treatment. Findings were confirmed in additional cohorts of patients with NSCLC receiving immune checkpoint blockade. RESULTS We identified a genetic variant of a killer cell immunoglobulin-like receptor (KIR) KIR3DS1 that is associated with primary resistance to PD-1 blockade in patients with NSCLC. This association could be confirmed in independent cohorts of patients with NSCLC. In a multivariate analysis of the pooled cohort of 135 patients, the progression-free survival was significantly associated with presence of the KIR3DS1 allele (HR, 1.72; 95% confidence interval, 1.10-2.68; P = 0.017). No relationship was seen in cohorts of patients with NSCLC who did not receive immunotherapy. Cellular assays from patients before and during PD-1 blockade showed that resistance may be due to NK-cell dysfunction. CONCLUSIONS We identified an association of the KIR3DS1 allelic variant with response to PD-1-targeted immunotherapy in patients with NSCLC. This finding links NK cells with response to PD-1 therapy. Although the findings are interesting, a larger analysis in a randomized trial will be needed to confirm KIRs as predictive markers for response to PD-1-targeted immunotherapy.

Abstract
Abstract
Reinvigoration of tumor-specific T-cells by cancer immunotherapies, in particular PD-1/PD-L1 blocking agents, has greatly improved clinical outcome in multiple cancer types. Nevertheless, durable clinical benefit is currently limited to a small number of patients. To achieve a better understanding of the immunologic determinants of response to anti-PD-1 therapy, we assessed transcriptional and functional profiles of tumor-infiltrating lymphocyte (TIL) subsets from non-small cell lung cancer specimens. Thereby, we identified a transcriptionally distinct CD8 TIL pool with enriched capacity for tumor recognition. This TIL pool, termed PD-1T TILs, is characterized by bright PD-1 expression and constitutive CXCL13 secretion, which can mediate immune cell recruitment to tertiary lymphoid structures. Notably, the presence of PD-1T TILs correlates with response and survival in a small cohort of lung cancer patients treated with PD-1 blockade. To assess the role of PD-1T TILs and CXCL13 for response to PD-1 blockade in other cancer types, we developed a platform using human tumor explants to visualize immunologic responses to anti-PD-1 on a patient-specific level. Analysis of the cellular and soluble tumor microenvironment composition as well as of treatment-induced changes in tumor-infiltrating immune cells revealed immunologic responses to anti-PD-1 in 5 different cancer types. Of note, responding tumors in different tumor types were characterized by a clear enrichment in both PD-1T TILs and CXCL13 production. Collectively, our data reveal a distinct state of PD-1 bright lymphocytes that are enriched for tumor-reactivity in human cancer, making them an attractive proxy for the antitumor potential of the intratumoral T-cell pool. Furthermore, we established technology using human tumor explants to measure the immunologic response to T-cell checkpoint inhibition on a personalized basis. Finally, with this approach we identified PD-1T TILs and CXCL13 as determinants for response to anti-PD-1 in multiple cancer types, opening potential new avenues for therapeutic intervention and improved patient selection.

Abstract
Cancer immunotherapy with antibodies targeting immune checkpoints such as the PD-1/PD-L1 pathway have emerged as breakthrough treatment for multiple solid tumors with high response rates and durable remissions. Despite the benefit for patients and encouraging safety profile, severe inflammatory reactions are observed in some patients. Such immune-related adverse events (irAEs) frequently lead to temporary or permanent cessation of the treatment and require systemic immunosuppression yet underlying mechanisms of irAEs are not known in detail. Here, we describe the T cell-mediated immune reaction in irAE lesions of four patients that developed pneumonitis during therapy with a PD-1 blocking antibody. Immunohistochemical analysis was performed to map the environment of the inflammatory lesions. Tumor infiltrating T cell clones were identified by sequencing the T cell receptor, and comparison with clones from peripheral blood or secondary lymphoid organs. A significant overlap of clones infiltrating irAE lesions and tumors was found. The most prevalent clones were also expanded in peripheral blood, but only a minor fraction of clonal overlap was found. Our findings suggest that irAE lesions in patients under PD-1 blockade are infiltrated by T cells with similar specificity as tumor-infiltrating T cells. These results raise the possibility that the immune response is elicited in these patients against antigens shared by the tumor and distant organs affected by irAEs.

Abstract
Dysfunctional T cells present in malignant lesions are characterized by a sustained and highly diverse expression of inhibitory receptors, also referred to as immune checkpoints. Yet, their relative functional significance in different cancer types remains incompletely understood. In this study, we provide a comprehensive characterization of the diversity and expression patterns of inhibitory receptors on tumor-infiltrating T cells from patients with non-small cell lung cancer. In spite of the large heterogeneity observed in the amount of PD-1, Tim-3, CTLA-4, LAG-3, and BTLA expressed on intratumoral CD8(+) T cells from 32 patients, a clear correlation was established between increased expression of these inhibitory coreceptors and progression of the disease. Notably, the latter was accompanied by a progressively impaired capacity of T cells to respond to polyclonal activation. Coexpression of several inhibitory receptors was gradually acquired, with early PD-1 and late LAG-3/BTLA expression. PD-1 blockade was able to restore T-cell function only in a subset of patients. A high percentage of PD-1(hi) T cells was correlated with poor restoration of T-cell function upon PD-1 blockade. Of note, PD-1(hi) expression marked a particularly dysfunctional T-cell subset characterized by coexpression of multiple inhibitory receptors and thus may assist in identifying patients likely to respond to inhibitory receptor-specific antibodies. Overall, these data may provide a framework for future personalized T-cell-based therapies aiming at restoration of tumor-infiltrating lymphocyte effector functions.

Abstract
T-cell bispecific antibodies (TCBs) are a novel therapeutic tool designed to selectively recruit T-cells to tumor cells and simultaneously activate them. However, it is currently unknown whether the dysfunctional state of T-cells, embedded into the tumor microenvironment, imprints on the therapeutic activity of TCBs. We performed a comprehensive analysis of activation and effector functions of tumor-infiltrating T-cells (TILs) in different tumor types, upon stimulation by a TCB targeting folate receptor 1 and CD3 (FolR1-TCB). We observed a considerable heterogeneity in T-cell activation, cytokine production and tumor cell killing upon exposure to FolR1-TCB among different FolR1-expressing tumors. Of note, tumors presenting with a high frequency of PD-1hi TILs displayed significantly impaired tumor cell killing and T-cell function. Further characterization of additional T-cell inhibitory receptors revealed that PD-1hi TILs defined a T-cell subset with particularly high levels of multiple inhibitory receptors compared with PD-1int and PD-1neg T-cells. PD-1 blockade could restore cytokine secretion but not cytotoxicity of TILs in a subset of patients with scarce PD-1hi expressing cells; in contrast, patients with abundance of PD-1hi expressing T-cells did not benefit from PD-1 blockade. Our data highlight that FolR1-TCB is a promising novel immunotherapeutic treatment option which is capable of activating intratumoral T-cells in different carcinomas. However, its therapeutic efficacy may be substantially hampered by a pre-existing dysfunctional state of T-cells, reflected by abundance of intratumoral PD-1hi T-cells. These findings present a rationale for combinatorial approaches of TCBs with other therapeutic strategies targeting T-cell dysfunction.

Abstract
CD40 stimulation on antigen-presenting cells (APC) allows direct activation of CD8(+) cytotoxic T cells, independent of CD4⁺ T-cell help. Agonistic anti-CD40 antibodies have been demonstrated to induce beneficial antitumor T-cell responses in mouse models of cancer and early clinical trials. We report here that anti-CD40 treatment induces programmed death ligand-1 (PD-L1) upregulation on tumor-infiltrating monocytes and macrophages, which was strictly dependent on T cells and IFNγ. PD-L1 expression could be counteracted by coadministration of antibodies blocking the PD-1 (programmed death-1)/PD-L1 axis as shown for T cells from tumor models and human donors. The combined treatment was highly synergistic and induced complete tumor rejection in about 50% of mice bearing MC-38 colon and EMT-6 breast tumors. Mechanistically, this was reflected by a strong increase of IFNγ and granzyme-B production in intratumoral CD8⁺ T cells. Concomitant CTLA-4 blockade further improved rejection of established tumors in mice. This study uncovers a novel mechanism of acquired resistance upon agonistic CD40 stimulation and proposes that the concomitant blockade of the PD-1/PD-L1 axis is a viable therapeutic strategy to optimize clinical outcomes.

Abstract
BACKGROUND The evidence on the role of environmental factors in the development of type 1 diabetes is conflicting. Reducing potential bias and the variety of exposures, we investigated the association between type 1 diabetes risk and nutritional and environmental exposures in pre-school children. METHODS This nationwide population-based case-control study included 760 cases under 5 years of age newly diagnosed with type 1 diabetes during 1992-1995. From the general population, 1,871 controls were randomly selected and individually matched on age ( +/- 1 year), sex, and residence. Information on infant diet, foetal, perinatal and socio-economic factors, and familial diabetes was obtained by a parent-administered questionnaire. Data were analysed by multiple conditional logistic regression. RESULTS Duration of breastfeeding and age at introduction of bottle-feeding were inversely associated with type 1 diabetes risk according to a dose-response relationship (trend test p < 0.05). Adjusted odd ratios (95% CI) for a long breastfeeding period and a late introduction of bottle-feeding (>or=5 month versus < 2 weeks) were 0.71 (0.54-0.93) and 0.80 (0.62-1.04), respectively. Familial type 1 diabetes, maternal age > 40 years, and low birth weight were found more frequently among diabetic than among control children. Current cow's milk consumption, higher social status, and a larger family were associated with a reduced diabetes risk. Up to one half of the diabetic cases in the population could be attributed to modifiable exposures. CONCLUSIONS Our findings indicate that infant feeding is associated with type 1 diabetes risk and that a considerable part of new type 1 diabetic cases is potentially preventable.

This nationwide case-control study included 760 cases newly diagnosed with type 1 diabetes under five years of age during 1992-1995. 630 controls of the same age were selected from the case families' acquaintance. Information on infant diet, foetal, perinatal and socio-economic factors, and family history of diabetes was obtained by a parent-administered questionnaire. Data were analysed by multiple unconditional logistic regression. Duration of breastfeeding and age at introduction of bottle-feeding were inversely associated with type 1 diabetes risk according to a dose-response relationship (trend test p<0.05). Adjusted odd ratios (95%-CI) for a short breastfeeding period and an early introduction of formula feeding (<5 vs. > or =5 months) were 1.31 (1.01-1.69) and 1.34 (1.03-1.74), respectively. Familial type 1 diabetes was found more frequently among diabetic than among control children. Higher social status, late introduction of solid food (> or =5 month), and higher current cow's milk consumption (> or =200 ml/d) were associated with a reduced diabetes risk. A considerable proportion of the diabetic risk among preschool children was explained by modifiable exposures. Our findings indicate that infant feeding is causally associated with type 1 diabetes risk and that a considerable part of new type 1 diabetic cases is potentially preventable.

Abstract
Attention difficulties and poor balance are both common sequel following a brain injury. This study aimed to determine whether brain injured adults had greater difficulty than controls in performing a basic balance task while concurrently completing several different cognitive tasks varying in visuo-spatial attentional load and complexity. Twenty brain injured adults and 20 age-, sex- and education level-matched controls performed a balance-only task (step stance held for 30 s), five cognitive-only tasks (simple and complex non-spatial, visuo-spatial, and a control articulation task), and both together (dual tasks). Brain injured adults showed a greater centre of pressure (COP) excursion and velocity in all conditions than controls. Brain injured adults also demonstrated greater interference with balance when concurrently performing two cognitive tasks than control subjects. These were the control articulation and the simple non-spatial task. It is likely that distractibility during these simple tasks contributed to an increase in COP motion and interference with postural stability in stance. Performing visuo-spatial tasks concurrently with the balance task did not result in any change in COP motion. Dual task interference in this group is thus unlikely to be due to structural interference. Similarly, as the more complex tasks did not uniformly result in increased interference, a reduction in attentional capacity in the brain injured population is unlikely to be the primary cause of dual task interference in this group.

Abstract
AIMS/HYPOTHESIS According to the Th1/Th2 paradigm Type 1 diabetes and atopic diseases are assumed to be mutually exclusive on the individual level. We analysed the association between Type 1 diabetes and atopic diseases in a case-control design in order to test the hypothesis that atopic diseases in early childhood could protect against Type 1 diabetes. METHODS We carried out a nationwide population-based case-control study enrolling 760 cases newly-diagnosed with Type 1 diabetes under five years of age between July 1992 and December 1995 and 1871 controls randomly selected from the general population and individually matched on sex, age and place of residence. Information on atopic diseases was obtained by a mailed parent-administered questionnaire. Data were analysed by multivariate logistic regression adjusting for potential confounders (family history of diabetes, social status, duration of overall breast feeding, number of children in family, maternal age at delivery). RESULTS Atopic eczema was less frequent in diabetic (13.3%) than in non-diabetic children (18.0%) and was significantly associated with a reduced risk of Type 1 diabetes. The adjusted odds ratio was 0.71 (95% CI 0.53-0.96). Hay fever and asthma were not significantly associated with diabetes risk (OR 0.98 (95% CI 0.47-2.01) and 1.46 (95% CI 0.70-3.06), respectively). CONCLUSION/INTERPRETATION In this large population-based case-control study in pre-school children an inverse association was observed between atopic eczema and Type 1 diabetes. Thus, in accordance with the Th1/Th2 paradigm development of atopic eczema in early childhood could be protective against childhood Type 1 diabetes.

Abstract
In this paper the use of Clifford algebra in the parametrization of point groups in spaces of various dimensions is shown. Higher-dimensional spaces are of great interest especially when modulated crystals or quasicrystals are studied. While the quaternion units, which are useful to parametrize rotations in 3 dimensions, can be identified with rotations, the basic Clifford units may be regarded as mirrors from which all proper and improper symmetry operations can be generated. The practical implementation of this method of parametrization is demonstrated for the group of the hypercube in the 4-dimensional space, and generalisations to spaces of dimensions higher than 4 are suggested.

Abstract
AIMS/HYPOTHESIS To estimate the national incidence of Type I (insulin-dependent) diabetes mellitus in children under 5 years of age in Germany and to analyse temporal, seasonal, and geographical patterns of the diabetes incidence. METHODS During 1993-1995 newly diagnosed subjects were prospectively registered by the hospital-based 'German Paediatric Surveillance Unit' with monthly inquiries in all paediatric departments in Germany. Level of ascertainment was estimated by capture-recapture-analysis using two independent regional data sources. RESULTS During 1993-1995 the national incidence was 8.10 (95 %-CI: 7.61, 8.61) per 100 000 person-years, ranging in-between lower rates in west European countries and higher rates in northern Europe. Degree of ascertainment was about 85 %. Male to female ratio was 1.11 (95 %-CI: 0.98, 1.25). Compared with results of previous regional studies in the east and the south-west of Germany a 3- and 1.3-fold incidence increase was observed, respectively. Multivariate Poisson regression analysis showed season, geographical region, and interactions of age at onset with sex and calendar year to be independent significant predictors of the incidence. Incidence variation by age was different between boys and girls. A significant incidence increase by calendar year was found in 3- and 4-year-old children only. In summer and fall the incidence was higher than in winter and springtime, in the northern parts of the country higher than in the southern parts. CONCLUSION/INTERPRETATION This study reports first national incidence data of Type I diabetes in children under the age of 5 years in Germany. Observed marked temporal, seasonal, and geographical incidence variations strongly support the causal role of environmental factors in disease aetiology.

Abstract
Between 1 November 1993 and 31 October 1996, admissions to paediatric departments for Bordetella pertussis complications were reported to a nationwide, hospital-based active surveillance system. The case definition included pertussis complicated by pneumonia, apnoea requiring assisted ventilation, seizures, encephalopathy or a combination of these. Two hundred sixteen cases of pertussis complications were registered. 57.4% of them were in infants, 50.9% of them less than 6 months old. There were five deaths, three previously healthy children died. At the time of hospital admission, 106 cases would have been eligible for at least three doses of pertussis vaccine, only four (3.8%) had received the recommended number of immunisations. From the second quarter of 1995, the reported number of cases declined. The decrease coincides with an improvement of pertussis vaccination coverage between 1992 and 1995 due to an increased use of acellular vaccines. The reduction of complicated pertussis was observed even in age-groups too young for the recommended vaccinations. The observed decrease could be due to the increase in vaccination coverage with interruption of the chain of transmission to the younger age-groups, to a cyclic decrease in pertussis cases, or to a combination of both. Continued surveillance will provide information on the epidemiological trend of hospitalisations for pertussis complications in the first European country to have introduced vaccination with acellular vaccines on a large scale.

Abstract
PURPOSE of the study was to detect vessels indirectly in conspicuous focal findings of the breast by means of measurement of blood flow by using colour-coded duplex sonography (CCDS) and to examine whether additional criteria can be defined to determine the pathological relevance of breast tumours. MATERIALS AND METHODS In a prospective study 149 patients were investigated, in whom either palpable breast lesions had been noticed or focal findings in imaging diagnostics. The perfusion in the focus and its surroundings (if present) was demonstrated and documented by means of CCDS. The investigation results were compared and contrasted with the histological findings after the operation. RESULTS Indirect detection of the vessels depended on the size of the malignant tumours and was successful in 41.7% of cases with a tumour diameter of < or = 1 cm, in 90% of cases with a diameter of 1-2 cm and in 100% of cases with a diameter of > 2 cm. Carcinoma and metastases could be detected with a sensitivity of 87.5% and overall specificity of 56.9%. No typical perfusion pattern allowing appraisal of the pathologic relevance was seen. Postoperative scars did not show perfusion in any case. CONCLUSIONS CCDS is of limited suitability only for determining the relevance of breast tumours, but provides additional diagnostic information especially on T1 tumours having a diameter between 1 and 2 cm. According to our results obtained so far, CCDS appears to be reliable and informative in differential diagnosis of tumour recurrence and an older scar.

Abstract
S-fimbriated Escherichia coli, which cause sepsis and meningitis in the newborn, bind to sialic acid-containing glycoprotein structures on the surface of human buccal epithelial cells. The dependence of this binding on host age was examined. S-fimbriated E. coli adhered in comparable numbers to cells in newborns, infants, children and adults (23.0 +/- 8.6; 23.1 +/- 11.5; 24.7 +/- 7.9; 28.9 +/- 8.8). Thus, the increased susceptibility of neonates to infections caused by S-fimbriated E. coli cannot be explained by enhanced adhesion to epithelial cells.
