Abstract
The existing information supports the use of this material as described in this safety assessment. 3,7-Dimethyl-3,6-octadienal was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog citral (CAS # 5392-40-5) show that 3,7-dimethyl-3,6-octadienal is not expected to be genotoxic and provided a calculated margin of exposure (MOE) >100 for the repeated dose toxicity and developmental and reproductive endpoints. Data from the read-across analog citronellal (CAS # 106-23-0) provided 3,7-dimethyl-3,6-octadienal a No Expected Sensitization Induction Level (NESIL) of 7000 μg/cm2 for the skin sensitization endpoint. The phototoxicity/photoallergenicity endpoints were evaluated based on ultraviolet (UV) spectra; 3,7-dimethyl-3,6-octadienal is not expected to be phototoxic/photoallergenic. The local respiratory toxicity endpoint was evaluated using the threshold of toxicological concern (TTC) for a Cramer Class I material, and the exposure to 3,7-dimethyl-3,6-octadienal is below the TTC (1.4 mg/day). The environmental endpoints were evaluated; 3,7-dimethyl-3,6-octadienal was found not to be persistent, bioaccumulative, and toxic (PBT) as per the International Fragrance Association (IFRA) Environmental Standards, and its risk quotients, based on its current volume of use in Europe and North America (i.e., Predicted Environmental Concentration/Predicted No Effect Concentration [PEC/PNEC]), are <1.

Abstract
In vitro methods that can replace animal testing in the identification of skin sensitisers are now a reality. However, as cell culture and related techniques usually rely on animal-derived products, these methods may be failing to address the complete replacement of animals in safety assessment. The objective of this study was to identify the animal-derived products that are used as part of in vitro methods for skin sensitisation testing. Thus, a systematic review of 156 articles featuring 83 different in vitro methods was carried out and, from this review, the use of several animal-derived products from different species was identified, with the use of fetal bovine serum being cited in most of the methods (78%). The use of sera from other animals, monoclonal antibodies and animal proteins were also variously mentioned. While non-animal alternatives are available and methods free of animal-derived products are emerging, most of the current methods reported used at least one animal-derived product, which raises ethical and technical concerns. Therefore, to deliver technically and ethically better in vitro methods for the safety assessment of chemicals, more effort should be made to replace products of animal origin in existing methods and to avoid their use in the development of new method protocols.

Abstract
This is the report of a workshop organised by the European Centre for the Validation of Alternative Methods (ECVAM). ECVAM's main goal, as defined in 1993 by its Scientific Advisory Committee, is to promote the scientific and regulatory acceptance of alternative methods that are of importance to the biosciences and which replace, reduce or refine the use of laboratory animals. One of the first priorities set by ECVAM was the implementation of procedures that would enable it to become well informed about the state-of-the-art of non-animal test development and validation, and the potential for the possible incorporation of alternative tests into regulatory procedures. It was decided that this would be best achieved by the organization of ECVAM workshops on specific topics, at which small groups of invited experts would review the current status of various types of in vitro tests and their potential uses, and make recommendations about the best ways forward (Anonymous, 1994). The workshop on "The use of in vitro systems for evaluating Immunotoxicity" was held at ECVAM (Ispra), Italy, on 24th-26th November 2003. The participants represented academia, national organizations, international regulatory bodies and industry. The aim of the workshop was to review the state-of-the-art in the field of in vitro immunotoxicology, and to develop strategies towards the replacement of in vivo testing. At the end of this report are listed the recommendations that should be considered for prevalidation and validation of relevant and reliable procedures, that could replace the use of animals in chemical and cosmetics toxicity testing.

Abstract
Skin sensitization remains a major environmental and occupational health hazard. Animal models have been used as the gold standard method of choice for estimating chemical sensitization potential. However, a growing international drive and consensus for minimizing animal usage have prompted the development of in vitro methods to assess chemical sensitivity. In this paper, we examine existing approaches including in silico models, cell and tissue based assays for distinguishing between sensitizers and irritants. The in silico approaches that have been discussed include Quantitative Structure Activity Relationships (QSAR) and QSAR based expert models that correlate chemical molecular structure with biological activity and mechanism based read-across models that incorporate compound electrophilicity. The cell and tissue based assays rely on an assortment of mono and co-culture cell systems in conjunction with 3D skin models. Given the complexity of allergen induced immune responses, and the limited ability of existing systems to capture the entire gamut of cellular and molecular events associated with these responses, we also introduce a microfabricated platform that can capture all the key steps involved in allergic contact sensitivity. Finally, we describe the development of an integrated testing strategy comprised of two or three tier systems for evaluating sensitization potential of chemicals.

Abstract
Assessment of allergenic potential of chemicals is performed using animal models, such as the murine local lymph node assay, which does not distinguish between respiratory and contact allergens. Progress in understanding the mechanisms of skin sensitization, provides us with the opportunity to develop in vitro tests as an alternative to in vivo sensitization testing. The aim of the present study was to evaluate the possibility to use intracellular interleukin-18 (IL-18) production to assess in vitro the contact sensitization potential of low molecular weight chemicals. The human keratinocyte cell line NCTC2455 was used. Cells were exposed to contact allergens (cinnamaldehyde, dinitrochlorobenzene, glyoxal, isoeugenol, p-phenylediamine, resorcinol, tetramethylthiuram disulfide, 2-mercaptobenzothiazole, 4-nitrobenzylbromide), to proaptens (cinnamyl alcohol, eugenol), to respiratory allergens (diphenylmethane diisocyanate, trimellitic anhydride, ammonium hexachloroplatinate) and to irritants (sodium lauryl sulphate, salicylic acid, phenol). Cell associated IL-18 were evaluated 24 later. At not cytotoxic concentrations (cell viability higher of 75%, as assessed by MTT reduction assay), all contact sensitizers, including proaptens, induced a dose-related increase in IL-18, whereas both irritants and respiratory failed. Similar results were also obtained using primary human keratinocytes. Results were reproducible, and the method could be transferred to another laboratory, suggesting the potential use of the test in immunotoxicity testing strategies. Overall, results obtained indicated that cell-associated IL-18 may provide an in vitro tool for identification and discrimination of contact versus respiratory allergens and/or irritants.

Abstract
Langerhans cells (LC) are key mediators of contact allergenicity in the skin. However, no in vitro methods exist which are based on the activation process of LC to predict the sensitization potential of chemicals. In this study, we have evaluated the performances of MUTZ-3, a cytokine-dependent human monocytic cell line, in its response to sensitizers. First, we compared undifferentiated MUTZ-3 cells with several standard human cells such as THP-1, KG-1, HL-60, K-562, and U-937 in their response to the strong sensitizer DNCB and the irritant SDS by monitoring the expression levels of HLA-DR, CD54, and CD86 by flow cytometry. Only MUTZ-3 and THP-1 cells show a strong and specific response to sensitizer, while other cell lines showed very variable responses. Then, we tested MUTZ-3 cells against a wider panel of sensitizers and irritants on a broader spectrum of cell surface markers (HLA-DR, CD40, CD54, CD80, CD86, B7-H1, B7-H2, B7-DC). Of these markers, CD86 proved to be the most reliable since it detected all sensitizers, including benzocaine, a classical false negative in local lymph node assay (LLNA) but not irritants. We confirmed the MUTZ-3 response to DNCB by real-time PCR analysis. Taken together, our data suggest that undifferentiated MUTZ-3 cells may represent a valuable in vitro model for the screening of potential sensitizers.

Abstract
Current approaches to skin sensitisation risk assessment are dependent upon the availability of information regarding two fundamental parameters. Firstly, data relating to the relative skin sensitising potency of the chemical, and secondly, information regarding likely conditions of human exposure. During the past two decades, much has been achieved in terms of refining methods capable of informing these parameters. For example, the development of the local lymph node assay (LLNA) has made it possible to predict skin sensitising hazard, and to determine relative skin sensitising potency, in a way that was not possible previously. Taken together with accurate information about predicted exposure, such potency data can be used to facilitate the derivation of effective risk assessments. However, although the LLNA provides an integrated assessment of skin sensitising activity, it does require the use of experimental animals and there is growing enthusiasm for designing robust alternative approaches that will reduce or obviate that need. Progress is being made in defining alternative experimental strategies that avoid animal use, but it is clear that accurate characterisation of skin sensitisation hazards will require the effective integration of various sources of information. For this reason, we exemplify here one possible approach that, in theory, provides a framework for not only the identification of skin sensitising chemicals, but also the estimation of relative sensitising potency. This paradigm depends upon development of an understanding of the various biological, biochemical and chemical factors that impact on the allergenic properties of chemicals and the acquisition of skin sensitisation, and an ability to measure these in vitro.

Abstract
The intracellular mechanisms involved in the early phase of dendritic cell (DC) activation upon contact with chemical sensitizers are not well known. The strong skin sensitizer 2,4-dinitrofluorobenzene (DNFB) was shown to induce the activation of mitogen-activated protein kinases (MAPK) in DC. In the present study, we investigated a putative role for oxidative stress in DNFB-induced MAPK activation and upregulation of the costimulatory molecule CD40. In a DC line generated from fetal mouse skin, DNFB induced a significant increase in protein oxidation, measured by the formation of carbonyl groups, while it had almost no effect on lipid peroxidation. The antioxidants glutathione and vitamin E, which inhibit protein and lipid oxidation, respectively, were used to assess the role of oxidative stress in DNFB-induced MAPK activation. Glutathione, but not vitamin E, inhibited DNFB-induced p38 MAPK and ERK1/2 phosphorylation, whereas none of the antioxidants interfered significantly with the DNFB-induced upregulation of CD40 protein levels. Taken together, these results indicate that DNFB activates p38 MAPK and ERK1/2 via production of reactive oxygen species, and that protein oxidation plays an important role in MAPK activation.

Abstract
BACKGROUND The intracellular mechanisms involved in the activation of DCs during sensitization in allergic contact dermatitis (ACD) are not known. OBJECTIVE Here, we investigated the effect of a strong sensitizer, 2,4-dinitrofluorobenzene (DNFB) on the activity of MAPKs in a dendritic cell (DC) line generated from fetal mouse skin (FSDC), and the results were correlated with the expression of a costimulatory molecule upregulated upon DC maturation, CD40. METHODS Phosphorylation of ERK1/2 (pERK1/2) and p38 MAPK (pp38 MAPK), and CD40 protein levels, were determined by Western blot. Cellular localization of pERK1/2 and pp38 MAPK were determined by immunocytochemistry using phospho-specific antibodies. RESULTS Although with different kinetics, DNFB activated ERK1/2 and p38 MAPK, and induced the translocation of the phosphorylated forms of the kinases to the nucleus. In addition, DNFB upregulated significantly CD40 protein levels in FSDC. However, 2,4-dichloronitrobenzene (DCNB), an inactive analogue of DNFB, did not affect significantly the phosphorylation of MAPKs and CD40 protein levels. SB203580 and SB202190, inhibitors of the p38 MAPK activity, inhibited DNFB-induced CD40 upregulation, although this effect did not reach statistical significance. In contrast, PD 98059 and U0126, inhibitors of mitogen or extracellular signal-regulated kinase (MEK), had no effect on the CD40 upregulation induced by DNFB. CONCLUSIONS Taken together, these results indicate that the strong sensitizer DNFB activates ERK1/2 and p38 MAPK signaling pathways, and upregulates CD40 protein levels. However, MAPKs do not play a major role in the induction of CD40, one of the phenotypic markers of DC maturation.

Abstract
Immune-mediated hypersensitivity reactions include exaggerated humoral or cell mediated responses to specific antigens and may culminate in adverse, potentially life threatening effects. The immune status of the host and presence of infections or other disorders can alter the kind and extent of immune mediated side effects in individuals. Such variability in the immune status may influence the type of idiosyncratic reaction(s) that patients manifest. The issues typically encountered from a drug development standpoint include the potential for contact hypersensitivity, respiratory sensitivity, systemic hypersensitivity, photoallergy, and pseudoallergy. There are no accepted in vitro or in vivo models available to measure and predict all types of hypersensitivity reactions in humans. There is a need for the development of preclinical models to predict all types of hypersensitivity reactions in humans. The FDA immunotoxicology guidance document recommends doing preclinical testing in animal models for topical and inhalational drugs before initiation of multiple dose studies in humans. Any signs of potential immune related drug hypersensitivity should be further evaluated in an attempt to further understand the potential for hypersensitivity reactions in humans. In summary, existing preclinical models have limited capability for prediction of drug allergy in humans except for topical and inhalational drugs. Additional tools are needed to evaluate drugs in early development and improve performance of existing assays.

Abstract
Chemical haptens and metal ions interact with proteins and thereby become recognizable by T and B lymphocytes. They induce the production of proinflammatory cytokines and chemokines by various cell types due to triggering of innate immune responses. This is an important prerequisite for the activation of the adaptive immune system and the development of diseases like allergic contact dermatitis and adverse drug and autoimmune reactions. Our increasing knowledge about the molecular basis of hapten and metal ion recognition by T cells and about the pathomechanisms of contact hypersensitivity and chemical-induced autoimmune reactions allows concomitant progress in the development of modern strategies for immunotherapy and will hopefully enable more specific intervention in hapten- and metal ion-induced human diseases in the future.

Abstract
In the present study, reconstructed human epidermis (RHE) was used as an in vitro model to discriminate 1-chloro-2,4-dinitrobenzene (DNCB), nickel sulfate (NiSO(4)), oxazolone (OXA), 2,4-dinitrofluorobenzene (DNFB) and 2,4,6-trinitrobenzenesulfonic acid (TNBS) as skin sensitizers from benzalkonium chloride (BC), benzoic acid (BA) and sodium lauryl sulfate (SLS) as skin irritants. Our criteria were (a) the differential IL-1alpha and IL-8 synthesis and release (b) cytotoxicity assessment by MTT assay. When the RHE are topically treated with the sensitizers, very low levels of extra- and intracellular IL-1alpha are observed although they induce significant cytotoxicity. In contrast, they exhibit a sharp maximum of IL-8 release. In the presence of the tested irritants, we observe the inverse cytokine release profile, although they induce dose-dependent cytotoxicity profiles similar to those observed with the sensitizers. Finally, IL-1alpha mRNA upregulation is observed after topical application of both sensitizers and irritants, but only the latter significantly increase extracellular IL-1alpha. In conclusion, our results suggest that the associated determination of IL-8, with IL-1alpha, and MTT conversion are at least necessary to discriminate and classify, in a single assay, irritant and sensitizing agents and represent a potential in vitro alternative to two classical in vivo assays.

Abstract
Novel transcript profiling technologies allow simultaneous measurement of the changes in expression of many hundreds or many thousands of genes. The availability of these methods has brought about revolutionary changes in many areas of investigative biology, where analyses of patterns of gene expression, rather than of individual genes, are being employed. The application of these technologies to toxicology (toxicogenomics) offers new opportunities for both mechanistic toxicity research and predictive toxicology. Here we provide an overview of the basic approaches used in this field. The development of a series of toxicology-specific microarrays in our own laboratory is discussed, together with an example of one area of mechanistic research, chemical allergy, where we believe judicious application of toxicogenomics will make an important contribution.

CD40-CD40 ligand (L) interactions play a pivotal role in immune-mediated inflammatory responses via the activation of antigen-presenting cells (APCs). To investigate the effects of continuous activation of resident tissue APCs, in this case the Langerhans cells (LCs) of the skin, CD40L expression was targeted to the basal keratinocytes of the epidermis of mice using the keratin-14 promoter. Approximately 80% of the transgenic (Tg) mice spontaneously developed dermatitis on the ears, face, tail, and/or paws. Compared with littermates, Tgs had a >90% decrease in epidermal LCs yet increased numbers within the dermis suggestive of enhanced emigration of CD40-activated LCs. Tgs also displayed massive regional lymphadenopathy with increased numbers of dendritic cells and B cells. Moreover, a decrease in IgM and an increase in IgG1/IgG2a/IgG2b/IgE serum concentrations was detectable. Screening for autoantibodies revealed the presence of antinuclear antibodies and anti-dsDNA antibodies implicative of systemic autoimmunity. Accordingly, renal Ig deposits, proteinuria, and lung fibrosis were observed. Adoptive transfer of T cells from Tgs to nonTg recipients evoked the development of skin lesions similar to those found in the Tgs. Dermatitis also developed in B cell-deficient CD40L Tg mice. These findings suggest that in situ activation of LCs by CD40L in the skin not only leads to chronic inflammatory dermatitis but also to systemic mixed-connective-tissue-like autoimmune disorders, possibly by breaking immune tolerance against the skin.

Abstract
Langerhans cells are the most potent antigen-presenting cells in the skin and play a critical role in the induction of contact allergy. Research on the phenotypical and functional changes of LCs occurring after application of skin sensitizers indicated their use as an in vitro model for the screening of chemicals. In the present investigations, LCs from human skin explants served as the test system. The application of this cell system has been aggravated by the difficulty in isolating sufficient numbers of live LCs from skin. This disadvantage was overcome by the culture of immature dendritic cells from peripheral mononuclear blood cells. These cells can serve as a replacement for LCs as they bind haptens and show phenotypical and functional changes similar to LCs. The sensitizers NiSO(4), dinitrochlorobenzene, 2,4,6-trinitrobenzene sulfonic acid, alpha-hexylcinnamaldehyde and eugenol were applied. Both the expression of surface markers and the induction of intracellular interleukin-1 beta (IL-1 beta) were analyzed. No clear-cut results could be established for intracellular cytokine production, only NiSO(4) induced a remarkable number of IL-1 beta-positive cells. However, all skin sensitizers caused an up-regulation of the co-stimulatory molecule CD86, of intercellular adhesion molecule CD54 and of the HLA-DR antigen. The irritant sodium dodecyl sulfate (SDS) and the vehicle dimethyl sulfoxide (DMSO) had no effect.

Abstract
The development of in vitro methods for the identification of skin sensitizers based upon analysis of Langerhans cell (LC) function has been constrained by the fact that these cells represent only a minority population in the skin that, once isolated, alter their phenotype spontaneously and rapidly. Methods have been developed recently that allow the expansion in culture using appropriate cytokine conditions of LC-like dendritic cells (DCs) from certain tissues, including human peripheral blood. It has been demonstrated that culture of human blood-derived LC-like cells with selected potent contact allergens such as 2,4-dinitrofluorobenzene (DNFB) stimulates selective phenotypic changes, including the up-regulation of interleukin 1 beta (IL-1 beta) mRNA expression, under conditions where skin irritants are without effect. However, in our own previous investigations, we have observed that there appear to be differences between blood donors with respect to the responsiveness of DCs to DNFB-induced changes in IL-1 beta expression, differences that could compromise the utility of this approach as a screening method for contact allergens. We have therefore investigated donor variability in DC responsiveness to a panel of known human contact allergens (DNFB; paraphenylene diamine, PPD; methyl- chloroisothiazolinone/methylisothiazolinone, CMIT), to the skin irritant benzalkonium chloride and to the mitogen phorbol myristate acetate (PMA). Dendritic cells derived from all donors expressed IL-1 beta mRNA constitutively. Treatment of DCs isolated from donors with a responder phenotype to DNFB with PPD or CMIT resulted also in up-regulation of IL-1 beta mRNA expression, although such changes were always comparatively modest, generally resulting in a twofold induction compared with vehicle-treated controls. Dendritic cells derived from donors with a non-responder phenotype to DNFB failed also to respond to these additional contact allergens under conditions where the mitogen PMA caused similar increases in IL-1 beta expression to those observed for allergen-responsive donors. Benzalkonium chloride failed to provoke changes in the expression of this cytokine in any donor examined, irrespective of their responder phenotype. The temporal stability of the responder/non-responder DC phenotype was confirmed, with stable phenotypes with respect to DNFB-induced changes in IL-1 beta mRNA expression observed over a period of some 18 months. Fifty per cent (6/12) of donors tested over this period displayed a responder phenotype. These data demonstrate that chemical allergens do stimulate consistent changes in IL-1 beta mRNA expression in the proportion of donors who have a responsive phenotype, and that such responses are apparently selective for allergen using the relatively narrow range of materials assessed to date. However, the modest response to very strong contact allergens, coupled with the difficulties of responder/non-responder phenotypes, means that in its present form this approach does not lend itself to the routine assessment of skin sensitizing activity.

Abstract
Allergic contact dermatitis (ACD) is a cell-mediated immune response to small molecular weight chemicals that contact and penetrate the skin. There are a variety of characteristics that determine whether a chemical can function as a contact sensitizer (or allergen) including the ability to penetrate into the skin, react with protein and be recognized as antigenic by immune cells. The ultimate challenge for developing non-animal test methods for skin sensitization testing will be applying our mechanistic understanding of ACD to the design of predictive in vitro alternative test methods. Specifically, the in vitro approach should be designed so that a chemical's potential to penetrate the skin, react with protein/peptide (biotransformation may be required) and initiate an antigen-specific immune response is incorporated in the test methods developed. In this review, we have focused on cellular-based assays that have been developed or proposed for assessing a chemical's skin sensitization potential in vitro. All of the promising leads to date are based on observations made from in vivo studies conducted in animals and humans, and therefore have a strong mechanistic foundation. However, it remains to be demonstrated whether a single in vitro test, or several in vitro tests in combination, which model the critical steps in sensitization, can replace animal experiments for predicting contact allergic reactions in humans. Regardless, the future looks promising with continued development of our understanding of the chemical and biological aspects of allergic contact dermatitis, and most importantly, with the application of genomics/proteomics to this field on the immediate horizon.

Abstract
Novel approaches to testing of skin sensitizing chemicals have made use of immature dendritic cells (DCs) cultured from different hematopoietic progenitors. These cells resemble Langerhans cells (LCs), which are the most potent antigen presenting cells in the skin. Former research has focused on the phenotypic and functional changes of LCs after application of skin sensitizers. But it has proven difficult to isolate sufficient numbers of LCs from skin. This disadvantage is overcome by cultures of immature DCs providing high numbers of reactive cells. The aim of the present investigation was to test the response of DC cultures established from different blood donors to known sensitizers, an irritant and a vehicle. The sensitizers NiSO(4), dinitrochlorobenzene (DNCB), 2,4,6 trinitrobenzene sulfonic acid (TNBS), alpha-hexylcinnamaldehyde (Cinn) and eugenol (Eu) induced the up-regulation of the co-stimulatory molecule CD86, of intercellular adhesion molecule CD54 and of the HLA-DR antigen. The irritant sodium dodecyl sulfate (SDS) and the vehicle dimethyl sulfoxide (DMSO) had no effect. A high rate of responders within blood donors was found for NiSO(4), TNBS, Cinn and Eu, while DNCB was less effective. The augmentation of surface marker expression in dendritic cells obtained from peripheral human blood seems to be a promising readout in prescreening for strong and moderate sensitizers. This test could thus help to reduce animal numbers for in vivo testing.
