Megjegyzések:	Background Alopecia areata (AA) is an autoimmune disorder whose pathogenesisinvolves the collapse of the relati ve immune privilege (IP) of the hair follicle(HF). Given that vasoactive intestinal peptide (VIP) is an immunoinhibitory neu-ropeptide released by perifollicular sensory nerve ?bres, which play a role in IPmaintenance, it may modulate human HF-IP and thus be therapeutically relevantfor AA.Objectives To answer the following questions: Do human HFs express VIP recep-tors, and does their stimulation protect from or restore experimentally inducedHF-IP collapse? Is VIP signalling defective in AA HFs?Methods Firstly, VIP and VIP receptor (VPAC1, VPAC2) expression in human scalpHFs and AA skin was assessed. In HF organ culture, we then explored whetherVIP treatment can restore and/or protect from interferon-c-induced HF-IP col-lapse, assessing the expression of the key IP markers by quantitative (immuno-)histomorphometry.Results Here we provide the ?rst evidence that VIP receptors are expressed in theepithelium of healthy human HFs at the gene and protein level. Furthermore,VIP receptor protein expression, but not VIP+nerve ?bres, is signi?cantly down-regulated in lesional hair bulbs of patients with AA, suggesting defects in VIPreceptor-mediated signalling. Moreover, we show that VIP protects the HF fromexperimentally induced IP collapse in vitro, but does not fully restore it once col-lapsed.Conclusions These pilot data suggest that insuf?cient VIP receptor-mediated sig-nalling may contribute to impairing HF-IP in patients with AA, and that VIP is apromising candidate ♭HF-IP guardian' that may be therapeutically exploited toinhibit the progression of AA lesions.

Megjegyzések:	From birth, we are constantly exposed to bacteria, fungi and viruses, some of which are capable of transiently or permanently inhabiting our different body parts as our microbiota. The majority of our microbial interactions occur during and after birth, and several different factors, including age, sex, genetic constitution, environmental conditions and lifestyle, have been suggested to shape the composition of this microbial community. Propionibacterium acnes is one of the most dominant lipophilic microbes of the postadolescent, sebum-rich human skin regions. Currently, the role of this bacterium in the pathogenesis of the most common inflammatory skin disease, acne vulgaris, is a topic of intense scientific debate. Recent results suggest that Westernization strongly increases the dominance of the Propionibacterium genus in human skin compared with natural populations living more traditional lifestyles. According to the disappearing microbiota hypothesis proposed by Martin Blaser, such alterations in the composition of our microbiota are the possible consequences of socioeconomic and lifestyle changes occurring after the industrial revolution. Evanescence of species that are important elements of the human ecosystem might lead to the overgrowth and subsequent dominance of others because of the lack of ecological competition. Such changes can disturb the fine-tuned balance of the human body and, accordingly, our microbes developed through a long co-evolutionary process. These processes might lead to the transformation of a seemingly harmless species into an opportunistic pathogen through bacterial dysbiosis. This might have happened in the case of P. acnes in acne pathogenesis.
