Abstract
The resistant and recalcitrant nature of severe allergic contact dermatitis (ACD) makes its management challenging. With advances in the understanding of the cellular and molecular pathogenesis of ACD, newer therapeutic targets are becoming apparent. In particular, the use of biologics has gained momentum, given the specificity of their action. This article aims to review the presently available data on the use of biologics in ACD. English-language-based literature available on the use of biological therapy was thoroughly probed in the following databases as on October 14, 2019: PubMed, Google Scholar, The Cochrane library, Embase, Scopus, and EBSCO. The following keywords were used: "contact dermatitis", "allergens", "delayed-type hypersensitivity reaction", "biologics", "biological therapy", "monoclonal antibodies", "patch testing", "TNF-α inhibitors", "infliximab", "adalimumab", "etanercept", "dupilumab", "omalizumab", "secukinumab", "ustekinumab", "rituximab".

Abstract
Allergic contact dermatitis is a common disease within the family of delayed-type hypersensitivity reactions. In more severe cases of allergic contact dermatitis, topical steroids may prove insufficient, and systemic therapeutic agents are often used. Even when systemic therapies such as cyclosporine lead to improvement, withdrawal of these agents is challenging and can lead to undesirable morbidities. Currently, there are no systemic treatments indicated for the treatment of widespread recalcitrant contact dermatitis. This review discusses the targets of in-use off-label systemic medications and potential therapeutics in the pipeline.

Abstract
Antibody light chains (LCs), formerly considered a waste product of immunoglobulin synthesis, are currently recognized as important players in the activation of the immune response. However, very little is known about the possible immune regulatory functions of LCs. Recently, we reported that hapten-specific LCs coat miRNA-150-carrying exosomes produced by CD8+ suppressor T cells downregulating the contact hypersensitivity (CHS) reaction in an antigen-specific manner, in mice tolerized by intravenous administration of a high dose of hapten-coupled syngeneic erythrocytes. Thus, the current studies aimed at investigating the role of hapten-specific LCs in antigen-specific, exosome-mediated suppression of CHS effector cells. Suppressor T cell-derived exosomes from tolerized B-cell-deficient µMT-/-, NKT-cell-deficient Jα18-/-, and immunoglobulin-deficient JH-/- mice were nonsuppressive, unless supplemented with LCs of specificity strictly respective to the hapten used for sensitization and CHS elicitation in mice. Thus, these observations demonstrate that B1-cell-derived LCs, coating exosomes in vivo and in vitro, actually ensure the specificity of CHS suppression. Our research findings substantially expand current understanding of the newly discovered, suppressor T cell-dependent tolerance mechanism by uncovering the function of antigen-specific LCs in exosome-mediated, cell⁻cell communication. This express great translational potential in designing nanocarriers for specific targeting of desired cells.

Abstract
PURPOSE OF REVIEW The environment for the developing children is complex as they are exposed to a variety of activities and settings where potential environmental allergens may be encountered. Recent evidence supports the clinical benefit of patch testing young children suffering from recalcitrant dermatitis. While patch testing has been recently approved by the Food and Drug Administration in children ages 6-18 years old, patch testing strategies for young children of preschool age (between 2 and 6 years old) have yet to be defined. RECENT FINDINGS Allergic contact dermatitis is underdiagnosed among pediatric patients, particularly those suffering from concomitant atopic dermatitis as the interplay between the two diseases is complex. Recent reports in literature supported the clinical value, safety, and efficacy of patch testing pediatric patients. This review provides an overview of specific pediatric allergens, special considerations, practical modifications, and systematic exposure-driven guidance approaches toward patch testing preschoolers.

Abstract
We used a recently developed ambiguous-cue interpretation (ACI) paradigm to investigate whether 'optimism' and 'pessimism' as behavioural traits may be interrelated with immune functions in rodents. To this aim, in a series of ACI tests (cognitive bias screening, CBS), we identified rats that displayed 'pessimistic' and 'optimistic' traits. We found significant differences in immune biomarkers between 'optimistic' and 'pessimistic' animals. Moreover 'pessimism' was associated with significantly lower relative weight of the spleen and thymus, significantly decreased proliferative activity of splenocytes. Pessimism was associated with an increased production of interleukin-(IL)1β and IL-4, activin A, l-selectin, interferon (IFN)-γ and some chemokines and receptors for advanced glycation endproducts. The findings indicate an inflammatory profile in "pessimistic" animals.

A subset of AID-dependent B-1a cells initiates hypersensitivity and pneumococcal pneumonia resistance. Ann N Y Acad Sci 2015; 1362:200-14.

Abstract
We propose that there is a special B-1a B cell subset ("sB-1a" cells) that mediates linked processes very early after immunization to initiate cutaneous contact sensitivity (CS), delayed-type hypersensitivity (DTH), and immune resistance to pneumococcal pneumonia. Our published data indicate that in CS and DTH, these initiating processes are required for elicitation of the delayed onset and late-occurring classical T cell-mediated responses. sB-1a cells resemble memory B2 cells, as they are stimulated within 1 h of immunization and depend on T helper cytokines-uniquely IL-4 from hepatic iNKT cells--for activation and rapid migration from the peritoneal cavity to the spleen to secrete IgM antibody (Ab) and Ab-derived free light chains (FLCs) by only 1 day after immunization. Unlike conventional B-1a (cB-1a) cell-produced IgM natural Ab, IgM Ab produced by sB-1a cells has high Ag affinity owing to immunoglobulin V-region mutations induced by activation-induced cytidine deaminase (AID). The dominant cB-1a cells are increased in immunized AID-deficient mice but do not mediate initiation, CS, or pneumonia resistance because natural Ab has relatively low Ag affinity because of unmutated germ-line V regions. In CS and DTH, sB-1a IgM Ag affinity is sufficiently high to mediate complement activation for generation of C5a that, together with vasoactive mediators such as TNF-α released by FLC-sensitized mast cells, activate local endothelium for extravascular recruitment of effector T cells. We conclude by discussing the possibility of functional sB-1 cells in humans.

Abstract
The endogenous estrogens are important modulators of the immune system and its functions. However, their effects are rather complex and many aspects have not been studied. In this study, we used the 1-chloro-2,4-dinitrobenzene (DNCB)-induced contact dermatitis as a disease model and investigated the effect of estriol (E3), along with two other estrogens, 17β-estradiol and estrone, on the pathogenesis of contact hypersensitivity. A series of parameters, such as ear swelling, skin inflammation, antigen-specific immunoglobulins, and lymphocyte compositions in peripheral lymphoid organs, were evaluated in mice following development of contact dermatitis. We found that administration of all three estrogens elicited strong inhibition of DNCB-induced dermatitis, while E3 exerted the strongest suppressive effect. Administration of E3 alleviated dermatitis, and this effect was accompanied by decreases in serum DNCB-specific immunoglobulins, such as IgA, IgG1, IgG2a, and IgG2b. Besides, treatment with E3 reduced B cell population, especially IgG-producing cells in the peripheral lymphoid organs following the induction of dermatitis. These observations consistently suggest that the antibody (Ab)-mediated humoral immune reactions play a critical role in the pathogenesis of DNCB-induced contact dermatitis. The results from this study demonstrate, for the first time, that estrogen administration has a strong suppressive effect on the pathogenesis of contact dermatitis. These findings offer important insights concerning the pathogenic role of antigen-specific Abs in contact dermatitis and the treatment of chemical-induced, Ab-mediated skin hypersensitivity reactions in humans.

Abstract
Haptens are small molecule irritants that bind to proteins and elicit an immune response. Haptens have been commonly used to study allergic contact dermatitis (ACD) using animal contact hypersensitivity (CHS) models. However, extensive research into contact hypersensitivity has offered a confusing and intriguing mechanism of allergic reactions occurring in the skin. The abilities of haptens to induce such reactions have been frequently utilized to study the mechanisms of inflammatory bowel disease (IBD) to induce autoimmune-like responses such as autoimmune hemolytic anemia and to elicit viral wart and tumor regression. Hapten-induced tumor regression has been studied since the mid-1900s and relies on four major concepts: (1) ex vivo haptenation, (2) in situ haptenation, (3) epifocal hapten application, and (4) antigen-hapten conjugate injection. Each of these approaches elicits unique responses in mice and humans. The present review attempts to provide a critical appraisal of the hapten-mediated tumor treatments and offers insights for future development of the field.

Abstract
In 2057 consecutive subjects admitted to the Department of Pathology, Section of Immunology of the Verona University Hospital, CD19+ and CD5/CD19 double positive cells were determined to assess the behaviour of total peripheral B-lymphocytes and B-1a (CD5+) compartments in humans during aging. We show that the absolute number of total B lymphocytes increases about three-fold from the baseline conditions in the first year of life and progressively decreases until adult age. A slower decrease was detected from the adult age onwards. A similar behaviour has been observed within the B-1a subset of B-lymphocytes, although the decrease after the adult age seems more pronounced. Possible physiological explanations and/or implications for the disease states are taken into account.

Abstract
Allergic contact dermatitis (ACD) is one of the most common skin diseases, consisting of sensitization and elicitation phases. With the advancement of technology and the discovery of new types of immune cells, our knowledge of the immunological mechanisms of contact hypersensitivity (CHS) as a murine model of ACD has expanded significantly in the past decade. For example, by introducing regulatory T cells, CD4(+) T-helper 17 cells, and Langerin-positive dermal dendritic cells, the initiation and termination mechanism of CHS has been revealed. In addition, the role of mast cells in CHS, long a matter of debate, has become apparent by developing conditional mast cell-deficient mice. Moreover, the role of the innate immunity system, such as that of Toll-like receptor signaling, has made a breakthrough in this field. In this review, we will integrate the recent advancement of immunological mechanisms of both the sensitization and elicitation phases of CHS into the classic view, and we will discuss updated mechanisms on its development and future directions.

Abstract
Prior studies of classical 24 h responses in TNP-Cl (picryl chloride) allergic contact sensitivity (CS), showed mediation by Th1 cells in CBA mice, and established that 24 h elicitation of responses requires an early 2 h CS-initiating component dependent on iNKT cells, IL-4 and B-1 B cells. Here, we studied the other form of cytotoxic T cell (Tc1) CS in DNFB sensitized BALB/c mice and determined that similar CS-initiation also is required. We systematically tested each step of the initiation pathway in this model. Thus, DNFB Tc1 CS was significantly impaired in iNKT cell deficient CD1d(-/-) and Jα18(-/-) mice, IL4Rα(-/-) and STAT-6(-/-) mice, and also in pan B-cell deficient JH(-/-) mice. Further, the Tc1 DNFB CS-initiating component, like Th1 response to TNP-Cl, was elicited by only 1-day after immunization, due to B-1 cells. In summary, we show that CS-Initiation also is required in Tc1 CS. Further, we have newly determined regulatory support of both the early and late components of DNFB induced Tc1 CS by iNKT cells and γδ-T cells. In summary, both iNKT cells and assisting γδ-T cells are involved in initiating and effector phases of DNFB induced CS.

Abstract
Inflammation is a crucial step in the development of allergic contact dermatitis. The primary contact with chemical allergens, called sensitization, and the secondary contact, called elicitation, result in an inflammatory response in the skin. The ability of contact allergens to induce allergic contact dermatitis correlates to a great extent with their inflammatory potential. Therefore, the analysis of the sensitizing potential of a putative contact allergen should include the examination of its ability and potency to cause an inflammation. In this study, we examined the inflammatory potential of different weak contact allergens and of the strong sensitizer 2,4,6-trinitrochlorobenzene (TNCB) in vitro and in vivo using the contact hypersensitivity model, the mouse model for allergic contact dermatitis. Cytokine induction was analysed by PCR and ELISA to determine mRNA and protein levels, respectively. Inflammation-dependent recruitment of skin-homing effector T cells was measured in correlation with the other methods. We show that the sensitizing potential of a contact allergen correlates with the strength of the inflammatory response. The different methods used gave similar results. Quantitative cytokine profiling may be used to determine the sensitizing potential of chemicals for hazard identification and risk assessment.

Abstract
Natural killer T (NKT) cells are known to be specifically activated by α-galactosylceramide (α-GalCer) via their interaction with CD1d. At that time, NKT cells mediate autoreactivity and eventually induce hepatic injury. As these immune responses resemble acute autoimmune hepatitis, it was examined whether autoantibody production and the activation of autoantibody-producing B-1 cells were accompanied by this phenomenon. Autoantibodies against Hep-2 cells and double-stranded DNA were detected in sera as early as day 3 (showing a peak at day 14) when mice were treated with α-GalCer. On day 3, B220(low) cells appeared in the liver. These B220(low) cells were CD5(-) (i.e. B-1b cells) and CD69(+) (an activation marker). Primarily, such B220(low) cells were present in the peritoneal cavity, but the proportion of B220(low) cells increased with the administration of α-GalCer even at this site. In parallel with the appearance of B220(low) cells in the liver, hepatic lymphocytes acquired the potential to produce autoantibodies in in vitro cell culture in the presence of lipopolysaccharide. These results suggested that hepatic injury induced by α-GalCer administration resembled acute autoimmune hepatitis and that the major effector lymphocytes were NKT cells with autoreactivity and autoantibody-producing B-1 cells.

Abstract
Allergic contact dermatitis (ACD), one of the commonest occupational diseases, is a T-cell-mediated skin inflammation caused by repeated skin exposure to contact allergens, i.e. nonprotein chemicals called haptens. Allergic contact dermatitis, also referred to as contact hypersensitivity, is mediated by CD8+ T cells, which are primed in lymphoid organs during the sensitization phase and are recruited in the skin upon re-exposure to the hapten. Subsets of CD4+ T cells endowed with suppressive activity are responsible for both the down-regulation of eczema in allergic patients and the prevention of priming to haptens in nonallergic individuals. Therefore, ACD should be considered as a breakdown of the skin immune tolerance to haptens. Recent advances in the pathophysiology of ACD have demonstrated the important role of skin innate immunity in the sensitization process and have revisited the dogma that Langerhans cells are mandatory for CD8+ T-cell priming. They have also introduced mast cells as a pivotal actor in the magnitude of the inflammatory reaction. Finally, the most recent studies address the nature, the mode and the site of action of the regulatory T cells that control the skin inflammation with the aim of developing new strategies of tolerance induction in allergic patients.

Abstract
BACKGROUND Dinitrochlorobenzene-induced contact hypersensitivity is widely considered as a cell-mediated rather than antibody-mediated immune response. At present, very little is known about the role of antigen-specific antibodies and B cells in the development of dinitrochlorobenzene-induced hypersensitivity reactions, and this is the subject of the present investigation. METHODOLOGY/PRINCIPAL FINDINGS Data obtained from multiple lines of experiments unequivocally showed that the formation of dinitrochlorobenzene-specific Abs played an important role in the development of dinitrochlorobenzene-induced contact hypersensitivity. The appearance of dinitrochlorobenzene-induced skin dermatitis matched in timing the appearance of the circulating dinitrochlorobenzene-specific antibodies. Adoptive transfer of sera containing dinitrochlorobenzene-specific antibodies from dinitrochlorobenzene-treated mice elicited a much stronger hypersensitivity reaction than the adoptive transfer of lymphocytes from the same donors. Moreover, dinitrochlorobenzene-induced contact hypersensitivity was strongly suppressed in B cell-deficient mice with no DNCB-specific antibodies. It was also observed that treatment of animals with dinitrochlorobenzene polarized Th cells into Th2 differentiation by increasing the production of Th2 cytokines while decreasing the production of Th1 cytokines. CONCLUSIONS/SIGNIFICANCE In striking contrast to the long-held belief that dinitrochlorobenzene-induced contact hypersensitivity is a cell-mediated immune response, the results of our present study demonstrated that the production of dinitrochlorobenzene-specific antibodies by activated B cells played an indispensible role in the pathogenesis of dinitrochlorobenzene-induced CHS. These findings may provide new possibilities in the treatment of human contact hypersensitivity conditions.

Abstract
BACKGROUND The inflammation of atopic eczema (AE) is orchestrated not only by T cells predominantly but also B cells, eosinophils and dendritic cells. Recently, a role of invariant natural killer T (NKT) cells has been reported in bronchial asthma and allergy. Natural killer T cells express a restricted repertoire of T-cell receptor alpha/beta and produce interferon (IFN)-gamma and/or interleukin (IL)-4 upon activation. AIM OF THE STUDY To determine the presence of NKT cells in lesional AE skin in comparison with other eczematous disorders and to analyse their cytokine expression. METHODS Immunofluorescence stainings were carried out using antibodies recognizing NKT cells, CD3+ and CD4+ cells, IFN-gamma and IL-4. RESULTS Natural killer T cells have been detected in small numbers in the majority of AE specimens as well as in atopy patch test (APT) reactions, allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD). In AE, the proportion of NKT cells among CD3+ cells was approximately 5%. NKT cells expressed both IFN-gamma and IL-4 in AE, APT and ACD but predominantly IFN-gamma in ICD. CONCLUSION Natural killer T cells are part of the inflammatory infiltrate of AE as well as APT, ACD and ICD, suggesting a pathogenic role of NKT cells in eczematous skin disorders. The pattern of IFN-gamma and IL-4 cytokine expression by NKT cells varied depending on the type of eczematous disease.

Abstract
BACKGROUND AND PURPOSE The phenolic compounds isoprenylhydroquinone glucoside (IHG), 3,5-dicaffeoylquinic acid (DCA), and its methyl ester (DCE) have previously been shown to inhibit both contact hypersensitivity (CHS) and peroxynitrite reactivity. The present work seeks to establish a relationship between the anti-inflammatory effect and the release of cytokines and tyrosine nitration in skin. EXPERIMENTAL APPROACH Murine CHS was developed by means of sensitization and challenge with dinitrofluorobenzene (DNFB) or oxazolone. Ear swelling was measured 24 and 96 h after challenge. Interleukin (IL)-1beta, IL-4, and tumour necrosis factor (TNF)-alpha were measured by ELISA; and the expression of inducible nitric oxide synthase (iNOS) was detected by Western blotting. Histological samples were analysed for 3-nitrotyrosine. KEY RESULTS In the oxazolone model, DCE reduced the 24 h swelling by 54% whereas the effect of DCA was lower (40% inhibition). All the test compounds reduced IL-1beta values 24 h after challenge with DNFB or oxazolone, DCE particularly inhibited IL-4 production (74% and 78%, respectively; P<0.01). Tyrosine nitration was also markedly reduced by DCE. In general, the test compounds limited the presence of polymorphonuclear (PMN) leukocytes in the skin. CONCLUSIONS AND IMPLICATIONS These results suggest that the effect of 3,5-dicaffeoylquinic esters on CHS is associated with a decrease in the production of interleukins, but not with the inhibition of iNOS expression. Moreover, esterification of the carboxyl group at C-1 enhanced protection against tyrosine nitration in the skin.

Abstract
Glucocorticoids (GCs) are widely used in the treatment of allergic skin conditions despite having numerous side effects. Here we use Cre/loxP-engineered tissue- and cell-specific and function-selective GC receptor (GR) mutant mice to identify responsive cell types and molecular mechanisms underlying the antiinflammatory activity of GCs in contact hypersensitivity (CHS). CHS was repressed by GCs only at the challenge phase, i.e., during reexposure to the hapten. Inactivation of the GR gene in keratinocytes or T cells of mutant mice did not attenuate the effects of GCs, but its ablation in macrophages and neutrophils abolished downregulation of the inflammatory response. Moreover, mice expressing a DNA binding-defective GR were also resistant to GC treatment. The persistent infiltration of macrophages and neutrophils in these mice is explained by an impaired repression of inflammatory cytokines and chemokines such as IL-1beta, monocyte chemoattractant protein-1, macrophage inflammatory protein-2, and IFN-gamma-inducible protein 10. In contrast TNF-alpha repression remained intact. Consequently, injection of recombinant proteins of these cytokines and chemokines partially reversed suppression of CHS by GCs. These studies provide evidence that in contact allergy, therapeutic action of corticosteroids is in macrophages and neutrophils and that dimerization GR is required.

Abstract
In cutaneous contact sensitivity there is an early elicited innate cascade of complement, mast cells, and platelets activated via IgM Abs. This response is required to initiate the elicitation of acquired classical contact sensitivity by leading to local recruitment of effector T cells. We recently performed in vivo experiments showing that collaboration is required between innate-like invariant Valpha14+ NKT cells (iNKT) and the innate-like B-1 B cell subset to induce this initiation process. Contact sensitization triggers iNKT cells to produce IL-4 to coactivate the B-1 cells along with specific Ag for production of the initiating IgM Abs. We now describe in vitro collaboration of iNKT and B-1 cells. Normal peritoneal B-1 cells, incubated in vitro with soluble Ag, and with 1-h in vivo immune iNKT cells producing IL-4, are activated to mediate the contact sensitivity-initiation cascade. The three components of this process can be activated by different Ag. Thus, 1-h iNKT cell activation, B-1 cell stimulation, and generation of immune effector T cells can be induced by sensitization with three different Ag to respectively generate IL-4 and Ag-specific IgM Abs, to recruit the Ag-specific effector T cells. These findings have relevance to allergic and autoimmune diseases in which infections can trigger exacerbation of T cell responses to allergens or to autoantigens.
