    Title translation AR101: therapy for peanut allergy finally in view?
    Abstract AR101: therapy for peanut allergy finally in view? Worldwide, the incidence of peanut allergy is increasing. Spontaneous tolerance only occurs in a small percentage of children who are allergic to peanuts. To date, no treatment for this potentially life-threatening condition has been proven effective. However, the recently published results of the PALISADE trial on oral immunotherapy with AR101 are promising. As AR101 has many side effects, and as it is unclear if tolerance persists after therapy is stopped, there is still a long way to go before AR101 can be added to the standard treatment for peanut allergy.

    Abstract Hypersensitivity reactions are overreactions of the immune system clinically seen as allergic and autoimmune diseases. Gell and Coombs originally described four different types of hypersensitivity reactions almost 60 years ago, and their description still applies in large parts. However, some modifications and extensions have been included in original definition. Especially in allergic diseases, it became clear that often, multiple types of hypersensitivity reaction can occur simultaneously. This improved insight is not only important for a better understanding of hypersensitivity disorders, but is especially of importance for improved diagnostics and directing therapeutic interventions.

    Abstract Despite the growing use of flow cytometry to analyze the functional characteristics of basophils, the intracellular signaling cascades that control their ability to elaborate various pro-allergic and inflammatory mediators and cytokines remain comparatively obscure. Additionally, some studies require the analysis of pro-allergic and inflammatory mediators, such as histamine, LTC4, and various basophil-derived cytokines (e.g., IL-4 and IL-13). Elucidation of intracellular signaling proteins by Western blotting, cytosolic free calcium concentration by spectrofluorophotometry, and detection of mediator releases, as well as analysis of gene expressions by RT-PCR, generally requires relatively large numbers of purified basophils. In selected assays, flow cytometry enables the analysis of relatively low cell numbers and purity for the expression of intracellular signaling proteins or measurement of cytosolic free calcium concentrations by basophil-specific gating strategies. Unfortunately, many aspects of signal transduction relevant to human basophils cannot be readily extrapolated from the use of basophil or mast cell lines. This chapter therefore focuses on how to employ primary human basophils for studying mediator releases and signaling characteristics.

    Abstract Atopic dermatitis (AD) or eczema is the most common chronic inflammatory skin disease. It is a multifactorial disease with local and systemic immune changes. Current therapies focus on restoring the local skin barrier or inhibiting immune responses. In this issue of the European Journal of Immunology, Sehra et al. [Eur. J. Immunol. 2016. 46:2609-2613] describe a mouse model with T-cell-specific expression of constitutively active Stat6 in Flaky tail mice, which have mutations in the Flg and Tmem79 genes. The authors describe that it is the combination of changes in the skin barrier proteins filaggrin and Tmem79, together with Th2 cytokine signaling in the constitutively active Stat6 transgene, that drives the immune-pathomechanism in AD. These results are consistent with human studies where it is demonstrated that diminished filaggrin expression in skin is a predisposing factor for AD, but is neither required nor sufficient for disease indicating that additional factors are required for disease development. The current mouse model by Sehra et al. could be instrumental in evaluation new therapeutic strategies for AD.

    Abstract Atopic dermatitis (AD) is a chronic inflammatory skin disease for which new targeted therapies are currently available. Due to the increased rates of ocular surface disease (OSD) reported during treatment with these new targeted treatments, more insight into the occurrence and pathomechanism of OSD in moderate-to-severe AD patients is needed. Therefore, this review's first part highlights that most patients with moderate-to-severe AD already have characteristics of OSD before starting targeted treatment. Remarkably, not all AD patients with OSD report ocular symptoms. OSD in AD is associated with less conjunctival goblet cells (GC) compared to healthy controls. In addition, OSD severity in AD patients is associated with high AD activity, the presence of eyelid and/or facial eczema, and high levels of AD-related severity biomarkers in tear fluid. The second part of this review highlights that pre-existing ocular pathology (e.g. in combination with the use of ophthalmic medication or eyelid eczema) may be associated with the development of dupilumab-associated ocular surface disease (DAOSD). During dupilumab treatment, DAOSD (which can be new-onset OSD or worsening of pre-existing OSD) is observed in approximately one-third of the dupilumab-treated AD patients. Anti-inflammatory ophthalmic treatment improves DAOSD, and dose reduction of dupilumab may also be an effective treatment option. The pathomechanism of DAOSD is still not fully elucidated. In a prospective study low, but stable conjunctival GC numbers were observed in moderate-to-severe AD patients, before and during dupilumab treatment. However, the Mucin 5 AC (MUC5AC) expression of GCs decreased during dupilumab treatment, suggesting an impairment of the GC function by dupilumab treatment. In addition, higher dupilumab tear fluid levels were found in dupilumab-treated AD patients with moderate-to-severe OSD compared to patients with no or mild OSD, whereas the dupilumab serum levels are similar. Clinicians should be aware of the frequent occurrence of OSD in moderate-to-severe AD patients, and a low-threshold referral to an ophthalmologist is recommended.

    Abstract Research in allergy has a long history in the Netherlands, although the relation with immunology has not always been appreciated. In many aspects Dutch researchers have made major contribution in allergy research. This ranges from the first characterization of house dust mite as an important allergen, the first characterization of human Th2 and Th1 T cell clones, to the development of diagnostic test systems. In this overview Aalberse and Knol have made an overview of the major contributions of Dutch immunologists in allergy.
