    ABSTRACT: A major impetus to initiating the Human Genome Project was the belief that information encoded in the human genome would "accelerate progress in understanding disease pathogenesis and in developing new approaches to diagnosis, treatment, and prevention in many areas of medicine". Alopecia areata (AA) is a notable example of how understanding the genetic basis of a disease can have an impact on the care of patients in a relatively short time. Our first genome-wide association study in AA identified an initial set of common variants that increase risk of AA, some of which are shared with other autoimmune diseases. Thus, there has already been rapid progress in the translation of this information into new therapeutic strategies for patients, as drugs are already on the market for some of these disorders that can now be tested in AA. Informed by the progress achieved with genetic studies for mechanistically aligned autoimmune diseases, we are poised to carry this work forward and interrogate the underlying disease mechanisms in AA. Importantly, future genetic studies aimed at identifying additional susceptibility genes will further establish the foundation for the application of precision medicine in the care of AA patients.

    ABSTRACT: Alopecia areata (AA) is a cell-mediated autoimmune disease that targets actively growing hair follicles in mammals, including humans and mice. Development of the C3H/HeJ spontaneous mouse model AA nearly 20 years ago provided a much needed tool to test the hypotheses and ultimately serve as a preclinical model for drug testing. Discoveries in both human AA patients and the mouse model supported each other and lead to discoveries on the incredibly complex genetic basis of this disease. The discovery that A/J, MRL/MpJ, SJL/J, and SWR/J strains also develop AA now allows genome-wide association mapping studies to expand the list of genes underlying this disease. Potential new targets for unraveling the pathogenesis of AA include the role of retinoic acid metabolism in the severity of disease and hair shaft proteins that may be either the inciting antigen or ultimate target of the immune reaction leading to breakage of the shaft causing clinical alopecia. Comparing these model systems with human and mouse clinical disease, for both discovery and validation of the discoveries, continues to resolve the complex questions surrounding AA.

    ABSTRACT: Although alopecia areata (AA) is not life threatening, it may lead to severe psychological disturbances, reducing the quality of life in all ages. Thus, a new animal model is needed for shedding more light onto the pathogenesis of this cell-mediated, organ-specific autoimmune disease to identify more effective therapeutic strategies. Recently, we succeeded in developing a new humanized mouse model of AA, which includes transplantation of healthy human scalp skin obtained from normal volunteers on to severe-combined immunodeficient mice. This is followed by intradermal injection of either autologous or allogeneic peripheral blood mononuclear cells, which had been cultured with high dose of IL-2 and enriched for natural killer group 2D-positive (NKG2D+) and CD56+ cells. This protocol leads to rapid and predictable development of focal hair loss, with all the characteristic clinical, histological, and immunohistochemical features of AA. This humanized mouse AA model underscores the functional importance of NKG2D+ and CD56+ cells in AA pathogenesis and promises to be instrumental for identifying novel AA treatment strategies.

    ABSTRACT: Although the association between alopecia areata (AA), psoriasis, and other autoimmune diseases has been well reported in the literature, an association with metabolic syndrome has not been reported. We present two young women with the combination of severe psoriasis, androgen excess, metabolic syndrome, thyroiditis, and AA. Both women ultimately progressed to treatment-resistant alopecia universalis. This constellation of autoimmunity and metabolic syndrome presents a therapeutic challenge while highlighting the need for full laboratory assessment of AA patients. Careful selection of biological treatment regimens may offer therapeutic benefit for both their psoriasis and AA while giving us experience with the newer biologics in AA.

    ABSTRACT: Alopecia areata, alopecia totalis, and alopecia universalis likely represent a constellation of related diseases with similar, yet distinct heritability markers. There is currently no known curative therapy that works universally for all patients. Pharmacogenomic research enables the pharmaceutical industry to understand variability of patient responses to drugs during clinical drug development and during post-marketing surveillance. Understanding the genetic basis for patient response/non-response can enable the development of individualized therapies for those patients with an inherited basis for altered response to drug therapy. There are multiple examples of drugs that now contain a recommendation for genetic testing before dosing in their drug labels, directing clinicians to obtain genetic information for each individual patient in order to help direct drug therapy.

    ABSTRACT: Alopecia areata (AA) is an autoimmune condition characterized by T cell-mediated attack of the hair follicle. The inciting antigenic stimulus is unknown. A dense perbulbar lymphocytic infiltrate and reproducible immunologic abnormalities are hallmark features of the condition. The cellular infiltrate primarily consists of activated T lymphocytes and antigen-presenting Langerhans cells. The xenon chloride excimer laser emits its total energy at the wavelength of 308 nm and therefore is regarded as a "super-narrowband" UVB light source. Excimer laser treatment is highly effective in psoriasis, another T cell-mediated disorder that shares many immunologic features with AA. The excimer laser is superior in inducing T cell apoptosis in vitro compared with narrowband UVB, with paralleled improved clinical efficacy. The excimer laser has been used successfully in patients with AA. In this context, evaluation of the potential benefit of 308-nm excimer laser therapy in the treatment of AA is clinically warranted. Herein, the use of a common treatment protocol with a specifically designed module to study the outcome of excimer laser treatment on moderate-to-severe scalp AA in adults is described.

    ABSTRACT: Cutaneous delivery of therapeutics represents a proven and attractive option for treating a variety of dermatologic conditions with minimal systemic side effects. Although there have been many innovations in drug delivery systems, the number of effective cutaneous drugs remains small, primarily because of the stratum corneum permeability barrier. Overcoming this barrier safely and reversibly to deliver large hydrophilic drugs cutaneously is one of the major challenges in the field of dermatologic therapy.

    ABSTRACT: Few dermatologic conditions carry as much anxiety and emotional distress as hair loss resulting from a disease condition such as alopecia areata or as a result of cytotoxic drug treatment, e.g., after chemotherapy. Bimatoprost 0.03% solution is a Food and Drug Administration-approved prescription product indicated for the treatment of eyelash hypotrichosis. The product was investigated in a double-masked, randomized, and placebo-controlled study in patients who had significant eyelash loss or hypotrichosis as a result of chemotherapy. Once-daily treatment with bimatoprost ophthalmic solution 0.03% to the upper eyelid margin restored eyelash growth and prominence more quickly than the slower, natural course of recovery observed in the vehicle control subjects. The eyelash prominence measured using a validated Global Eyelash Assessment (GEA) scale demonstrated a statistically significant increase over placebo following 6 months of treatment. Efficacy was also demonstrated using a validated objective digital image analysis methodology to show significant increase in eyelash length, thickness/fullness, and darkness in these patients. Bimatoprost was found to be well tolerated over the 1-year treatment period.

    ABSTRACT: IL-15 has a pivotal role in life and death of natural killer (NK) and CD8 memory T cells. IL-15 signals through a heterotrimeric receptor involving the common gamma chain (γc) shared with IL-2, IL-4, IL-7, IL-9, and IL-21, IL-2/IL-15 receptor β (IL-15Rβ) shared with IL-2 and a private IL-15Rα subunit. IFN- or CD40 ligand-stimulated dendritic cells coordinately express IL-15 and IL-15Rα. Cell surface IL-15Rα presents IL-15 in trans to cells that express IL-2/IL-15Rβ and γc. IL-15 is being used to treat patients with metastatic malignancy. However, IL-15 is an inflammatory cytokine involved in immunological memory including that to self, thereby playing a role in autoimmune diseases. These insights provide the scientific basis for clinical strategies directed toward diminishing IL-15 action. Dysregulated IL-15 expression was demonstrated in patients with rheumatoid arthritis, inflammatory bowel disease, psoriasis, celiac disease, and alopecia areata. The monoclonal antibody Hu-Mik-β-1 targets the cytokine receptor subunit IL-2/IL-15Rβ (CD122), blocks IL-15 transpresentation, and is being used in clinical trials in patients with autoimmune diseases. In parallel, clinical trials have been initiated involving the Jak2/3 (Janus kinase-2/3) inhibitor tofacitinib and Jak1/2 inhibitor ruxolitinib to block IL-15 signaling.

    ABSTRACT: Previous genetic epidemiological studies of psoriasis and alopecia areata demonstrated strong heritability in first-degree relatives and in twins. In recent years, these two conditions have emerged as two skin diseases that are starting to yield their secrets through genome-wide association studies. Both diseases manifest prominent human leukocyte antigen (HLA) associations, psoriasis primarily with major histocompatibility complex (MHC) Class 1, specifically HLA-Cw6, and alopecia areata primarily with MHC Class II. Despite these differences in HLA associations, both diseases have in common a prominent role for CD8+ lymphocytes. The purpose of this brief review is to present the recent developments in the genetics of psoriasis.

    ABSTRACT: Reported is a patient with severe alopecia areata, multiple autoimmune diseases (chronic lymphocytic thyroidis, primary ovarian failure), and Down syndrome. She had a poor response to topical treatment with glucocorticoids and minoxidil, but showed some improvement with glucocorticoid injections. At the time of evaluation, she had hair loss on 85-90% of her scalp. She was treated initially with oral prednisone 50 mg per day for 2 weeks, followed by a 3-month course of prednisone 10 mg per day and cyclosporine 125 mg (4 mg kg(-1)) two times per day. She responded well with excellent regrowth of hair on the scalp, and prednisone was tapered and ultimately discontinued. Importantly, her parents noted marked improvement in sense of well-being. Several months after discontinuing treatment, she developed hyperpigmentation on the trunk consistent with confluent and reticulated papillomatosis; she has several known risk factors for this disorder, but it is not clear if this is related to her previous treatment.

    ABSTRACT: Alopecia areata is an autoimmune skin disease resulting in the loss of hair on the scalp and elsewhere on the body. The disease most often occurs in childhood and affects males and females of all ages. The National Alopecia Areata Foundation conducts research summits every 2 years to review progress and create new directions in its funded and promoted research. The Foundation brings together scientists from all disciplines to get a broad and varied perspective. These summits are part of the Foundation's main strategic initiative, the Alopecia Areata Treatment Development Program to accelerate progress toward a viable alopecia areata treatment.

    ABSTRACT: Cytokines have pivotal roles in the maintenance of an appropriate immune response. Targeting cytokine receptors has been an effective means of treating immune-related disorders. In the past few years, research efforts have been directed toward cytokines' intracellular signaling pathways and, in particular, the JAK-STAT (Janus kinase-signal transducers and activation of transcription) signaling cascade. Recently, spearheaded by the development of effective drugs in cancer treatment, it has become clear that the targeting of intracellular protein kinases is a very attractive and feasible possibility for the treatment of autoimmune disorders. The targeting of the Janus kinases (JAKs) has been quite successful and two JAK inhibitors are now approved to be used in humans. Interestingly, although some of the inhibitors developed and tested to date have been shown to target more than one kinase, this promiscuity does not appear to be problematic. Novel second-generation, more specific inhibitors are under development, and in the next few years, we expect this class of drugs to become a powerful tool in the hands of clinician treating autoimmune diseases.

    ABSTRACT: The existing literature on alopecia areata (AA) clearly demonstrates patients' concerns related to physical symptoms, emotional well-being, mental health, social functioning, and other dimensions of daily functioning. Although questionnaires such as the Skindex-16 and the Dermatology Life Quality Index have been used, these questionnaires were validated for skin conditions other than AA as a chronic condition. The goals of this study are to develop a measure of quality of life, symptoms, and their impact for patients with AA called the Alopecia Areata Symptom Impact Scale (AASIS) and to provide psychometric evidence for its use. We used data from 1,400 patients from the National Alopecia Areata Registry together with clinical experts' reviews and quantitative approaches. The preliminary version of the AASIS with 13 items was administered to about 210 patients with AA. Results indicated that the AASIS measures three underlying constructs related to AA. These dimensions were impact of AA, hair loss, and physical skin symptoms. The internal consistency reliabilities of these subscales are 0.93, 0.86, and 0.81, respectively. Cognitive debriefing results showed that patients find the AASIS items easy to understand, clear, and concise. Preliminary evidence suggests that the AASIS is a reliable and valid measure of the symptoms and their impact in patients with AA.

    ABSTRACT: Alopecia areata (AA) may represent a CD8+T cell-mediated, organ-specific autoimmune disease in which as yet elusive autoantigens are recognized, once they become exposed by ectopic major histocompatibility complex class I expression by anagen hair follicles (HFs) that have lost their relative immune privilege (IP). On this basis, AA research is chiefly challenged with identifying the autoreactive CD8+T cells and their cognate autoantigens as well as key inducers of HF-IP collapse and "HF-IP guardians" that prevent and/or can restore IP collapse. However, natural killer group 2D-positive (NKG2D+) cells (incl. NK, NKT, and CD8+T cells) and NKG2D-activating ligands from the MICA (MHC I-related chain A) family may also have a key role in AA pathogenesis, as a massive infiltrate of IFN-γ-secreting NKG2D+ cells alone suffices to induce the AA phenotype. Therefore, we speculate that AA may represent a stereotypic, but distinct HF response pattern to inflammatory insults associated with HF-IP collapse.

    ABSTRACT: Alopecia areata is a common form of hair loss in which autoimmune-mediated destruction of hair follicles causes patchy hair loss, for which there is no adequate therapy. Parathyroid hormone (PTH) induces the hair cycle and promotes hair growth. PTH-CBD is a fusion protein of PTH and a bacterial collagen-binding domain (CBD), leading to targeted delivery to and retention in the skin collagen. We tested the effects of a single dose of PTH-CBD (low or high dose) on an animal model for alopecia areata, the C3H/HeJ engrafted mouse. In all the treated animals, there was a rapid (1-4 days) increase in hair growth, with sustained effects observed over a 2-month period (7/10 total treated mice<40% hair loss based on gray scale analysis, vs. 2/5 in vehicle control animals). Histological examination revealed massive stimulation of anagen VI hair follicles in treated animals despite an ongoing immune response. PTH-CBD thus shows promise as a therapy for alopecia areata, likely in conjunction with a mild immune suppressant, such as hydrocortisone cream.
