Abstract
Drug-Induced Enterocolitis Syndrome (DIES) is a drug-induced hypersensitivity reaction non-IgE mediated involving the gastrointestinal system that occurs 2 to 4 h after drug administration. Antibiotics, specifically amoxicillin or amoxicillin/clavulanate, represent the most frequent drugs involved. Symptoms include nausea, vomiting, abdominal pain, diarrhea, pallor, lethargy, and dehydration, which can be severe and result in hypovolemic shock. The main laboratory finding is neutrophilic leukocytosis. To the best of our knowledge, 12 cases of DIES (9 children-onset and 3 adult-onset cases) were described in the literature. DIES is a rare clinically well-described allergic disease; however, the pathogenetic mechanism is still unclear. It requires to be recognized early and correctly treated by physicians.

Abstract
We previously developed a test for detecting naturally occurring protein-induced skin sensitization based on the markers and criteria of the human cell-line activation test (h-CLAT) and showed that the h-CLAT was useful for assessing the allergenic potency of proteins. However, test proteins were contaminated with varying amounts of lipopolysaccharide (LPS), which might have contributed to the stimulation of CD86 and CD54 expression. In this study, we developed a method to exclude the effects of LPS in the assessment of skin sensitization by naturally occurring proteins. We tested two inhibitors [the caspase-1 inhibitor acetyl-Tyr-Val-Ala-Asp-chloromethylketone (Ac-YVAD-cmk; hereafter referred to as YVAD), which can mitigate the LPS-induced increases in CD54 expression, and polymyxin B (PMB), which suppresses the effect of LPS by binding to its lipid moiety (i.e., the toxic component of LPS)]. After a 24 hr exposure, YVAD and PMB reduced LPS-induced CD86 and CD54 expression. In particular, the effect of PMB was dependent upon pre-incubation time and temperature, with the most potent effect observed following pre-incubation at 37°C for 24 hr. Moreover, only pre-incubation with cell-culture medium (CCM) at 37°C for 24 hr showed an inhibitory effect similar to that of PMB, with this result possibly caused by components of CCM binding to LPS. Similar effects were observed in the presence of ovalbumin (with 1070 EU/mg LPS) and ovomucoid, and lysozyme (with 2.82 and 0.234 EU/mg LPS, respectively) in CCM. These results indicated that PMB and CCM effectively eliminated the effects of LPS during assessment of protein allergenicity, thereby allowing a more accurate evaluation of the potential of proteins to induce skin sensitization.

Abstract
Recently, animal testing has been affected by increasing ethical, social, and political concerns regarding animal welfare. Several in vitro safety tests for evaluating skin sensitization, such as the human cell line activation test (h-CLAT), have been proposed. However, similar to other tests, the h-CLAT has produced false-negative results, including in tests for acid anhydride and water-insoluble chemicals. In a previous study, we demonstrated that the cause of false-negative results from phthalic anhydride was hydrolysis by an aqueous vehicle, with IL-8 release from THP-1 cells, and that short-time exposure to liquid paraffin (LP) dispersion medium could reduce false-negative results from acid anhydrides. In the present study, we modified the h-CLAT by applying this exposure method. We found that the modified h-CLAT is a promising method for reducing false-negative results obtained from acid anhydrides and chemicals with octanol-water partition coefficients (LogKow) greater than 3.5. Based on the outcomes from the present study, a combination of the original and the modified h-CLAT is suggested for reducing false-negative results. Notably, the combination method provided a sensitivity of 95% (overall chemicals) or 93% (chemicals with LogKow > 2.0), and an accuracy of 88% (overall chemicals) or 81% (chemicals with LogKow > 2.0). We found that the combined method is a promising evaluation scheme for reducing false-negative results seen in existing in vitro skin-sensitization tests. In the future, we expect a combination of original and modified h-CLAT to be applied in a newly developed in vitro test for evaluating skin sensitization.

Abstract
OBJECTIVES Dendritic cells (DCs) are antigen-presenting cells that participate in the immune response; recently, it has been reported that growth hormone (GH) promotes their maturation. The aim of this study was to investigate mechanisms by which GH acts on DC maturation and activation. MATERIALS AND METHODS Human peripheral blood monocytes (HPBMs) were induced to become immature DCs and treated with GH to obtain mature DCs. An osteosarcoma mouse model was established by injection of LM8 cells to investigate anti-tumour effect of GH-induced DCs in vivo. RESULTS After administration of GH, DCs reduced miR-200a expression and nuclear Nrf2 accumulation; miR-200a down-regulation inhibited DC maturation. Nrf2 ubiquitination level was increased by Keap1 overexpression in murine bone marrow derived dendritic cells (BMDCs), which was cancelled by miR-200a in GH exposed cells. In vivo, tumour volume was significantly reduced by GH-treated DCs and the effect was reversed by overexpression of miR-200a. CONCLUSIONS GH promoted maturation and activation of DCs, and regulation of miR-200a played a part in this process by modulation of the Keap1/Nrf2 pathway.

Abstract
Drug-induced hypersensitivity reactions can cause a variety of serious diseases by involving drug-specific T-cells. Many of these reactions have been explained by the hapten concept, which postulates that small chemical compounds need to bind covalently to proteins to be recognized by the immune system. Due to their chemical reactivity, haptens stimulate the innate immunity by binding covalently to endogenous proteins and form so called hapten-carrier complexes, which are antigenic and induce T-cell responses. In recent years, a new concept has been developed since drug-induced hypersensitivity reactions were also observed with chemically unreactive drugs. This concept implies direct and reversible interactions of the drug between T-cell receptors (TCR) and major histocompatability complex (MHC) molecules. Therefore it was termed pharmacological interactions with immune receptors (p-i concept). Early observations on drug reacting T-cell clones (TCC) let believe that drugs bind first to the T-cell receptor since HLA molecules could be exchanged without affecting the drug reactivity. However, MHC molecules were always required for full activation of TCC. According to its strong HLA-B*5701 association, recent data on abacavir suggest that a drug could first bind to the peptide binding groove of the MHC molecule. The thereby modified HLA molecule can then be recognized by specific T-cells. Consequently, two types of reactions based on the p-i mechanism may occur: on the one hand, drugs might preferentially bind directly to the TCR, whereas in defined cases with strong HLA association, drugs might bind directly to the MHC molecule.

Abstract
PROBLEM Pregnancy requires that the maternal immune system adapt to prevent rejection of the fetal semi-allograft. This immunologic adaptation may contribute to pregnancy-related alterations in disease susceptibility and severity of infections from viral pathogens such as influenza virus. METHOD OF STUDY As part of a larger study investigating the maternal systemic immune response during pregnancy, peripheral blood was collected three times during pregnancy and twice post-partum to measure serum levels of 23 cytokines, chemokines, and growth factors. This longitudinal study design allowed each woman's post-partum blood draw to serve as her own comparison, thus controlling for interpersonal variability in expression levels. RESULTS When compared to the post-partum samples, significant pregnancy-related changes in IFNγ, TNFα, VEGF, GCSF, Eotaxin, and MCP-1 expression were observed. These changes have significant immunologic effects in vivo and in culture. CONCLUSION Pregnancy-associated changes to steady state serum cytokines may have important immunologic consequence.

Abstract
The accelerated migration of Langerhans cells (LCs) out of the epidermis and up-regulation of maturation markers, upon treatment with subtoxic concentrations of chemicals, were used as the criteria to determine the potential of allergenic chemicals capable of inducing a hapten-specific delayed-type hypersensitivity reaction. Here we report the findings of a study in which seven chemicals, coded and tested in a blind fashion, were classified as contact allergens or non-allergens using the human organotypic skin explant culture (hOSEC) model. All chemicals that were identified as a contact sensitizer on decoding induced a definite decrease in the number of CD1a and HLA-DR-positive epidermal LCs in the epidermis of the skin explants, as determined by both semiquantitative immunohistochemistry and quantitative flow cytometric analysis. A significant increase in the number of CD83(+) cells was accompanied by up-regulation of activation molecules in the epidermis of hOSEC exposed specifically to contact allergens. In contrast, there were only minor alterations in epidermal LC numbers, expression of CD83 and other activation markers by LCs when the biopsies were treated with non-toxic concentrations of non-allergenic irritants and vehicles. The data suggest that an increased epidermal LC migration and maturation accompanied by increased expression of activation markers could be used as end-point determinants to screen allergens in a non-animal alternative hOSEC model.

Abstract
Delayed immunologic recovery after allogeneic bone marrow transplantation (BMT) represents a major cause of morbidity and mortality that limits the overall success of the transplantation procedure. Recent clinical data suggest that a subset of donor dendritic cells may inhibit the graft-versus-tumor activity of donor T cells. We studied the immunoregulatory activity of donor dendritic cells in allogeneic BMT between major histocompatibility complex-disparate strains of mice. Bone marrow grafts enriched or depleted of CD11b- and CD11b+ dendritic cell subsets by immunomagnetic cell sorting were combined with small numbers of congenic splenic T cells. Recipients of CD11b-depleted bone marrow had significant posttransplantation expansion of donor spleen-derived CD4+ memory T cells compared with recipients of unmanipulated bone marrow. CD11b depletion enhanced the antitumor activity of the splenic donor T cells without producing significant graft-versus-host disease and resulted in long-term survival after a supralethal dose of T-cell leukemia administered after BMT. Expansion of donor spleen-derived T cells was proportional to the number of CD11b- dendritic cells in the bone marrow graft and was associated with increased levels of serum interferon-gamma. Thus, manipulating the content of donor antigen-presenting cells in allogeneic BMT is a novel strategy to activate donor memory T cells and enhance allogeneic graft-versus-leukemia effects with minimal graft-versus-host disease.

Abstract
The human organotypic skin explant culture (hOSEC) model is a promising alternative in vitro model for screening contact allergens. In this model, the chemical-induced migration of Langerhans cells (LCs) out of the epidermis, evaluated after a 24-h exposure period, is used as a measure of sensitizer potential. As skin irritants can also induce LC migration it is essential that concentrations of test chemicals are used that are not even weakly irritant. Using the hOSEC irritation model chemicals are classified as weak irritants if they are toxic after a 48-h exposure period. Toxicity is determined by methyl green-pyronine (MGP) staining of hOSEC. We studied three frequently used non-sensitizing skin irritants and six potent or frequent human sensitizers in a dose-response. A complete discrimination between non-sensitizers and contact sensitizers was obtained for the chemicals tested when the concentrations used were lower than the weak irritant concentrations. Frequency of positive allergen reactions in patch test of human populations correlated with the difference between weak irritant concentrations and the lowest concentration inducing significant LC migration. Sensitizer potency correlated with chemical irritancy as determined by keratinocyte death. For the compounds tested, the hOSEC model predicted allergenicity in humans better than the guinea pig maximization test and the mouse local lymph node assay.

Abstract
Dendritic cells (DCs) consist of a heterogeneous population of hematopoietic cells characterized by their unique dendritic morphology, their efficient antigen-presenting capability to activate naïve CD4+ and CD8+ T cells, as well as their lack of lineage-specific markers. Functional properties comparing umbilical cord blood monocyte-derived and umbilical cord blood stem cell-derived DCs have not yet been investigated. Human umbilical cord blood CD14+ monocytes and CD34+ stem cells were induced to differentiate into dendritic cells using 100 ng/mL granulocyte-macrophage colony-stimulating factor (GM-CSF), 25 ng/mL interleukin (II)-4, 2.5 ng/mL tumor necrosis factor alpha (TNF-alpha) and 100 ng/mL GM-CSF, 25 ng/mL stem cell factor, and 2.5 ng/mL TNF-alpha, respectively. Differentiated dendritic cells were CD80+, CD86+, CD83+, CD54+, CD1a+, CD11b+, CD11c+, HLA-DR+, CD34-, CD3-, CD19-, CD14-, and CD16-. Reverse transcription polymerase chain reaction revealed that differentiating monocytes initially expressed CD86 mRNA while CD80 mRNA appeared on Day 2. Differentiating stem cells expressed both CD80 and CD86 mRNA on Day 2 of culture. Mixed lymphocyte reaction was employed to evaluate the two types of lineage-derived DCs. Monoclonal antibodies (mabs) to CD80 and CD86 were employed to assess their costimulatory roles. CD14 and CD34 derived DCs prior to the functional assay were stimulated for 18 h with 0.1 and 1.0 mg/mL Escherichia coli lipopolyssacharide, respectively. A decrease in stimulation as depicted by decreased T-cell activation was significant with mabs to both CD80 and CD86 on monocyte-derived DCs while only mabs to CD86 induced decreased T-cell activation by stem cell-derived DCs. The varied functional role of CD80 and CD86 costimulatory molecules is associated with DC differentiation from distinct cord blood-isolated hematopoietic lineages. These studies demonstrate that DC association with distinct hematopoietic lineages is of relevance in transplantation and vaccine therapies.

Abstract
Dendritic cells (DCs) consist of a heterogeneous population of hematopoietic cells characterized by their unique dendritic morphology, their efficient antigen-presenting capability to activate naive CD4(+) and CD8(+) T cells, and their lack of lineage specific markers. Functional properties comparing umbilical cord blood monocyte-derived and umbilical cord blood stem cell-derived DCs have not yet been investigated. CD14(+) monocytes and CD34(+) stem cells were isolated from human umbilical cord blood and were induced to differentiate into dendritic cells using 100 ng/mL granulocyte-macrophage colony stimulating factor (GM-CSF), 25 ng/mL IL-4, 2.5 ng/mL tumor necrosis factor-alpha (TNF-alpha), 100 ng/mL GM-CSF, 25 ng/mL stem cell factor, and 2.5 ng/mL TNF-alpha, respectively. Flow cytometric analysis revealed that the 14-day-old dendritic cells were CD80(+), CD86(+), CD83(+), CD54(+), CD1a(+), CD11b(+), CD11c(+), HLA-DR(+), CD34(-), CD3(-), CD19(-), CD14(-), and CD16(-). Reverse transcription polymerase chain reaction was employed to detect expression of mRNA for CD80 and CD86. Differentiating monocytes initially expressed CD86 while CD80 appeared on day 2. Differentiating stem cells expressed CD80 and CD86 on day 2 of culture. The surface expression of CD80 and CD86 was studied over the course of differentiation. Mixed lymphocyte reaction was employed to evaluate the two types of lineage-derived DCs. Prior to the functional assay, CD14(+) and CD34(+) derived DCs were stimulated for 18 h with 0.1 mg/mL and 1.0 mg/mL E. coli lipopolyssacharide, respectively.

Macrophage colony-stimulating factor has not been considered as a factor responsible for dendritic cell or Langerhans cell development from hematopoietic progenitor cells. In this study, we examined whether macrophage colony-stimulating factor could be used instead of granulocyte-macrophage colony-stimulating factor for the in vitro development of Langerhans cells from hematopoietic progenitor cells. We replaced granulocyte-macrophage colony-stimulating factor with macrophage colony-stimulating factor from a serum-free culture containing granulocyte-macrophage colony-stimulating factor, stem cell factor, Flt3 ligand, tumor necrosis factor-alpha, and transforming growth factor-beta1. This serum-free culture medium containing macrophage colony-stimulating factor, but not granulocyte-macrophage colony-stimulating factor (macrophage colony-stimulating factor culture), could induce CD1a+ Birbeck granule+ Langerin+ E-cadherin+ factor-like XIIIa Langerhans cells. As a control, the culture of hematopoietic progenitor cells in this culture medium depleted of macrophage colony-stimulating factor or transforming growth factor-beta1 resulted in far fewer or null CD1a+ cells, respectively. Macrophage colony-stimulating factor increased the number of CD1a+ cells in a concentration-dependent fashion. These macrophage colony-stimulating factor-induced Langerhans cells were different from granulocyte-macrophage colony-stimulating factor-induced Langerhans cells in their decreased expression of CD11c and their immature phenotype. The decreased expression of CD11c, however, was recovered by culturing them with granulocyte-macrophage colony-stimulating factor, while they acquired a mature phenotype qby granulocyte-macrophage colony-stimulating factor, tumor necrosis factor-alpha, interleukin-1alpha, or lipo-polysaccharide. Macrophage colony-stimulating factor-induced Langerhans cells could stimulate allogeneic T cells. Interestingly, we could keep the growth and immature phenotypes of macrophage colony-stimulating factor-induced Langerhans cells for at least 28 d of culture. These studies demonstrated that macrophage colony-stimulating factor in cooperation with transforming growth factor-beta1 could induce Langerhans cell development from hematopoietic progenitor cells in vitro without granulocyte-macrophage colony-stimulating factor, which suggests the possibility that macrophage colony-stimulating factor plays a part in the Langerhans cell development in vivo. In addition, the culture using macrophage colony-stimulating factor presents a novel culture system to enable a large-scale and long-term culture of immature Langerhans cells.

Abstract
The properties of various vaccine-adjuvant formulations that are capable of inducing both systemic and common mucosal immunity subsequent to their intradermal administration are described. Effective mucosal adjuvants, including bacterial toxins, chemical enhancers of cyclic AMP, and the active form of vitamin D3, all shared the ability to promote dendritic cell migration from the skin to Peyer's patches subsequent to antigen induced maturation. Our data suggests that skin dendritic cells may function as effective antigen presenting cells for the induction of mucosal immune responses, if microenvironmental conditions are appropriately manipulated subsequent to their stimulation by antigen.

Abstract
Contact hypersensitivity is a major public health concern in most industrial countries, which is why predictive tests which could identify potential allergens are needed. We have established an in vitro approach for the detection of primary immune response. This model uses Langerhans-like dendritic cells (LLDC) derived from cord blood progenitors and autologous T lymphocytes, isolated from the same blood sample. Treatment of day 12-14 LLDC, with strong haptens trinitrobenzene sulfonic acid (TNP), fluorescein isothiocyanate (FITC) or Bandrowski's base (BB), results in the proliferation of T lymphocytes, whereas weak allergens and irritants, such as sodium dodecyl sulfate (SDS) are ineffective. The use of immature (day 8) LLDC and the addition of a 48 h stage of incubation after hapten contact, result in phenotypic maturation of LLDC in addition to lymphocyte activation in all the cultures with strong haptens. The 48 h stage of incubation, results in sensitization and in some cases the induction of T cell proliferation to citronellal (1/8), coumarine (1/8) and to a prohapten p-phenylenediamine (pPDA; 2/8). The phenotype of DC after 48 h of contact with a strong hapten, becomes that of mature DC (CD83(+), CD86(+) and HLA-DR(++)). With fragrance molecules, weak haptens and prohaptens, a comparable phenotype is observed only when T lymphocytes are activated. These data suggest that the unresponsiveness observed with weak haptens, may be the consequence on an incomplete maturation of LLDC.
