Abstract
The human papillomavirus (HPV), of which more than 200 different types have so far been identified, is an infectious disease impacting skin and mucous membranes. Several genera exist with distinct clinical impact. However, with ornamental tattoos increasing in popularity, a number of mostly cutaneous side effects have also been reported, such as infections, allergic reactions, or even a rise of malignant tumours within the tattoo. We report the first case of a β1-HPV-type infection in cutaneous lesions in terms of verrucae vulgares near a tattoo in an immunocompetent adult without pre-existing conditions, and discuss possible relationships and etiologic concerns of this association.

Abstract
Psoriasis is a chronic inflammatory disease affecting mainly the skin but which can be complicated by psoriatic arthritis (PsA).This autoimmune skin disorder concerns 2-5% of the world population. To date, the physiopathology of psoriasis is not still completely elucidated but many researches are ongoing which have led for example to the discovery of the Th17/Th22 pathway. The conventional therapeutic approaches (local or systemic route) appeal to various classes of drugs with complex mechanisms of action and non-negligible side effects. Although there is no therapy capable to cure psoriasis, the current goal is to relieve symptoms as longer as possible with a good benefit/risk ratio. That is one of the principal limits of conventional antipsoriatic drugs. New formulations based on nanoencapsulation are a promising opportunity to answer to this limit by offering an optimization of the conventional antipsoriatic drug use (higher activity, lower side effects and frequency of application, etc.). Herein, we tried to put in perspective the mechanistic insights (histological and immunological views) proposed into scientific literature these last years in order to have a better comprehension of psoriasis physiopathology resulting in skin lesions and PsA. The therapeutic armamentarium and the different strategies in the management of psoriasis are discussed in greater details. To finish, the field of encapsulation in nanoparticles is broached in order to put forward recent advances in innovative skin drug delivery systems (ISDDSs) of antipsoriatic active agents for a better efficacy, safety and compliance.

Abstract
Psoriasis is a multifactorial disease that involves genetic, immunological and environmental factors. During the last decade, several studies by genome scan on families or cases/controls helped to highlight more than ten loci "PSORS" located on different chromosomes and containing several candidate genes. Psoriasis appears as a genetic disease that follows the mixed model with the involvement of a major gene (PSORS1) and a set of minor genes with a variable penetrance depending on the locus. Genetic data have focused on the involvement of the immune system in the pathogenesis of psoriasis. It is now accepted that psoriasis is an immunological disease involving the response profiles TH1 and TH17. Much remains to be done to better elucidate the mechanisms involved in the genesis of psoriatic lesions to find new therapeutic targets.

Abstract
Whereas the antibody response to the anogenital human papillomaviruses (HPVs) is known to be mainly type-specific, correlated with the presence of viral DNA and mainly directed to conformational epitopes of the virion, it is not known if this applies also to the antibody response to cutaneous HPVs. For 434 non-immunosuppressed patients with skin lesions (squamous cell carcinoma and basal cell carcinoma of the skin, actinic keratosis and benign skin lesions), we compared HPV DNA status with seroreactivity to HPV pseudovirions (PsV) and to GST-L1 fusion proteins from HPV types -5, -6, -15, -16, -32 and -38. Biopsies from the skin lesions were tested for the presence of HPV DNA using three different PCR methods, with typing by sequencing. Serum samples from subjects with HPV DNA-positive biopsies and randomly selected serum samples from subjects with HPV DNA-negative biopsies were also tested with neutralization assays with HPV5, -38 and -76 PsV. Agreement of the three serological methods varied from poor to moderate. Type-specific seroprevalences among patients positive for the same type of HPV DNA (sensitivity of serology) was improved with the PsV-based method (mean of 40 %, maximum 63 %) compared with the GST-L1 method (mean of 20 %, maximum of 25 %). Neutralization was the most sensitive assay for HPV38 (50 %). In summary, cutaneous HPVs also appear to induce a type-specific antibody response that correlates with the presence of HPV DNA and that can be detected with improved sensitivity using PsV-based serology.

Abstract
Invasive squamous cell carcinoma (SCC) of the skin is one of the most common cancers in the United States, with no proven means for prevention other than systemic retinoids, which have significant toxicity, and sunscreen. We sought to determine the risk factors for invasive SCC on the face or ears in a high-risk population comprising 1,131 veterans in the Veterans Affairs Topical Tretinoin Chemoprevention (VATTC) Trial. Participants were required to have been diagnosed with at least two keratinocyte carcinomas (KCs) in the 5 years prior to enrollment. The median duration of follow-up was 3.7 years. Twenty-three percent of the participants developed a new invasive SCC, and the cumulative risk of invasive SCC was 30% at 5 years. The following factors independently predicted for new invasive SCCs: number of invasive SCCs and number of in situ SCCs in the 5 years prior to enrollment, actinic keratoses count at enrollment, a history of ever use of topical 5-fluorouracil, and total occupational time spent outdoors. In contrast, the use of angiotensin-convering enzyme inhibitors or angiotensin receptor blockers during the study and a history of warts anywhere on the body were found to protect against new invasive SCCs. These independent predictors remained the same for all SCCs (invasive and in situ combined). The number of basal cell carcinomas in the 5 years prior to enrollment, sunburns, sun sensitivity, and recreational sun exposure were not associated with new SCCs. These findings identify key risk factors for additional SCCs in patients with multiple prior KCs, and suggest that a history of warts may be associated with reduced SCC risk.

Abstract
Cutaneous human papillomaviruses (HPVs) have been associated with squamous cell carcinoma (SCC) in case-control studies, but there are limited data from prospective studies assessing whether virus exposure predicts risk of future cancer development. Two major biobanks, the Southern Sweden Microbiology Biobank (1971-2003) and the Janus Biobank (1973-2003) in Norway, containing samples from 850,000 donors, were searched for incident skin cancer for up to 30 years using registry linkages. Altogether, 2,623 donors with samples taken before diagnosis of SCC or basal cell carcinoma (BCC) of the skin were identified. Prediagnostic samples and samples from 2,623 matched controls were tested for antibodies against 33 types of HPV. Baseline seropositivity to HPV types in genus β species 2 was associated with SCC risk (odds ratio = 1.3, 95% confidence interval: 1.1, 1.7); this was also the case for samples taken more than 18 years before diagnosis (odds ratio = 1.8, 95% confidence interval: 1.1, 2.8). Type-specific persistent seropositivity entailed elevated point estimates for SCC risk for 29 HPV types and decreased point estimates for only 3 types. After multiple hypothesis adjustment, HPV 76 was significantly associated with SCC risk and HPV 9 with BCC risk. In summary, seropositivity for certain HPV types was associated with an increased risk for future development of SCC and BCC.

Abstract
High-risk α mucosal types of human papillomavirus (HPV) cause anogenital and oropharyngeal cancers, whereas β cutaneous HPV types (e.g. HPV8) have been implicated in non-melanoma skin cancer. Although antibodies against the capsid protein L1 of HPV are considered as markers of cumulative exposure, not all infected persons seroconvert. To identify common genetic variants that influence HPV seroconversion, we performed a two-stage genome-wide association study. Genome-wide genotyping of 316 015 single nucleotide polymorphisms was carried out using the Illumina HumanHap300 BeadChip in 4811 subjects from a central European case-control study of lung, head and neck and kidney cancer that had serology data available on 13 HPV types. Only one association met genome-wide significance criteria, namely that between HPV8 seropositivity and rs9357152 [odds ratio (OR) = 1.37, 95% confidence interval (CI) = 1.24-1.50 for the minor allele G; P=1.2 × 10(-10)], a common genetic variant (minor allele frequency=0.33) located within the major histocompatibility complex (MHC) II region at 6p21.32. This association was subsequently replicated in an independent set of 2344 subjects from a Latin American case-control study of head and neck cancer (OR=1.35, 95% CI=1.18-1.56, P=2.2 × 10(-5)), yielding P=1.3 × 10(-14) in the combined analysis (P-heterogeneity=0.87). No heterogeneity was noted by cancer status (controls/lung cancer cases/head and neck cancer cases/kidney cancer cases). This study provides a proof of principle that genetic variation plays a role in antibody reactivity to HPV infection.

Abstract
BACKGROUND Recent studies revealed that Betapapillomavirus (betaPV) infections are highly prevalent. Skin diseases such as psoriasis, characterized by keratinocyte hyperproliferation, and atopic dermatitis (AD), dominated by cutaneous inflammation, might have an impact on viral life cycle and immune response induction. OBJECTIVES To investigate whether betaPV infection is different in psoriasis and AD. METHODS Twenty-seven patients with psoriasis and 17 with AD were included for betaPV genotyping using eyebrow hairs, and for seroresponse determination. RESULTS BetaPV DNA was found significantly more often in patients with psoriasis than in those with AD (100% vs. 81%, P=0·022) and the mean number of betaPV types was higher (4·8 vs. 2·1 types, P=0·002). In contrast, the seroprevalence in patients with AD was significantly higher compared with that in patients with psoriasis (88% vs. 56%, P=0·023). Type-specific concordance of serological response to the betaPV type detected in eyebrow hairs was 27% in patients with psoriasis and 47% in those with AD (P=0·019). CONCLUSIONS We speculate that the condition of the skin and the immunological state of the patients have an important impact on the life cycle of betaPV.

Abstract
BACKGROUND It is currently unclear whether betapapillomaviruses (betaPV) play a role in the etiology of cutaneous squamous cell carcinoma (SCC). We investigated the association between betaPV antibodies and subsequent SCC in a population-based cohort study. METHODS Serum samples were collected in 1992 and/or 1996 from 1,311 participants of the community-based Nambour Skin Cancer Study. These were tested for the presence of L1 antibodies against 21 different betaPV types. Histologically diagnosed SCCs were ascertained through three full-body skin examinations and linkage with the local pathology laboratories. We used age- and sex-adjusted Cox proportional hazards models to analyze the relationship between betaPV antibodies and SCC occurrence from 1992 until 2007. RESULTS SCC was newly diagnosed in 150 people. No associations were found between the presence of any betaPV L1 antibodies and the occurrence of SCC (HR = 1.0), and stratification by sex, skin color, and sunburn propensity did not affect these results. However, among people who were less than 50 years old in 1992, the presence of betaPV antibodies was associated with a two-fold increased risk of SCC. There was no significant association between antibodies to any individual betaPV type examined and the later development of SCC. CONCLUSIONS Whether betaPV infection of the skin, and indirectly betaPV antibodies, are involved in the oncogenic process in the general population remains unclear, and this longitudinal study provides only limited support. IMPACT This study emphasizes the need for additional longitudinal studies of HPV (human papilloma virus) and SCC, to avoid the possibility of reverse causality in case--control studies.

Abstract
Information about serostability of cutaneous HPV types over time is very limited. We investigated seroprevalence and serostability of 37 different HPV types over 4½ years in an Australian population-based study. Sera and data were analyzed for 390 people who had never been diagnosed with SCC and had blood collected in 1992, 1993 and 1996. Eighty-six percent of participants were seropositive to at least one of the 37 HPV types at baseline. HPV-4 was the type with the highest seroprevalence (41%), followed by HPV-38 and HPV-8 (both 33%). Over 90% of people retained their baseline serostatus during the 4½ year follow-up. Highest serostability was observed for HPV-88 (99.7% stayed seropositive or seronegative), while HPV-65 was least stable with 17% altering their serostatus during follow-up. Seroprevalence to cutaneous HPV types are relatively stable over time, and a single measure can be used as a reasonable marker of long-term antibody status.

Abstract
Betapapillomavirus (betaPV) DNA and seroresponses are highly prevalent in the general population and both are frequently used as infection markers in epidemiological studies to elucidate an association with cutaneous squamous cell carcinoma (SCC). Little is known about the natural history of betaPV infection and the aspects of infection that drive antibody responses. To investigate the relationship between these markers, this study assessed whether the presence or persistence of betaPV DNA in eyebrow hairs and L1 antibodies of the same betaPV type co-occurred more frequently than would be expected by chance in both a cross-sectional assessment and a longitudinal study. betaPV DNA in plucked eyebrow hairs and L1 antibodies in serum were measured in 416 participants of the Australian community-based Nambour Skin Cancer Study in 1996. Similar data were available for a subset of 148 participants in 2003. Observed co-occurrence of betaPV DNA and antibodies was compared with expected values based on prevalence. A case-wise concordance index was used to calculate the overall concordance of betaPV DNA and antibodies of the same type. No significant associations were found between the presence or persistence of betaPV DNA and antibody responses. The age and sex of the host did not influence the association, and nor did SCC status or a history of sunburns. It was concluded that betaPV antibody responses in adults are not primarily driven by betaPV infection as measured in eyebrow hairs. Other factors, such as viral load, may play a more pivotal role in the induction of detectable seroresponses.

Abstract
A case-control study was conducted in 140 people with histology proven cutaneous squamous cell carcinoma (SCC) and 454 controls, nested within 2 cohorts of organ transplant recipients (OTR) recruited in London and Oxford between 2002 and 2006. All participants had a skin examination, completed a questionnaire and had serum tested for antibodies against the L1 antigen of 34 HPV types using Luminex technology. SCC was more common in men than women (odds ratio [OR] = 1.7, 95% confidence interval [CI]: 1.1-2.8, p = 0.02) and in people with susceptibility to burn easily (OR = 3.0, 95%CI: 1.9-4.8; p < 0.001). The risk increased with increasing age (p-trend < 0.001), increasing time since transplant (p-trend < 0.001), increasing self-reported number of sunburns as a child (p-trend < 0.001) and with the presence of viral warts (p < 0.001). As expected, antibodies against HPV 16 were associated with a self-reported history of an abnormal cervical smear among women (OR 5.1, 95%CI: 2.6-10.2) and antibodies against HPV 6 were associated with a self-reported history of genital warts (OR 4.0, 95%CI: 2.2-7.2). However, no clear associations between any of the HPV types examined (including cutaneous betaHPVs) and SCC were identified. For example, the seroprevalence of HPV 5 was 15% among cases and 9% among controls (p = 0.09) and the seroprevalence of HPV 8 was 23% among cases and 21% among controls (p = 0.6). Nor was seropositivity to multiple types associated with SCC. These serological data do not provide evidence for a role for HPV in the aetiology of cutaneous SCC among OTR in two UK-based populations.

Abstract
Cutaneous human papillomavirus type 8 (HPV8) is carcinogenic in patients with epidermodysplasia verruciformis. Transgenic mice with the complete early region (CER) of HPV8 spontaneously developed papillomas, dysplasia and squamous cell carcinomas of the skin. To characterize the role of individual early genes in carcinogenesis, the E6 and E6/E7 genes were expressed separately in transgenic mice. Nearly all HPV8-E6-positive mice spontaneously developed multifocal tumours, characterized by papillomatosis, hyperkeratosis and varying degrees of epidermal dysplasia. In 6 % of the cases, the tumours became malignant, comparable with HPV8-CER mice. Thus, in the murine epidermis, E6 is the major oncogene necessary and sufficient to induce spontaneous tumour development up to the level of squamous cell carcinoma. To evaluate the synergistic effects of UV light and wound healing, the skin of HPV8 mice was irradiated with UVA/UVB light or wounded with punch biopsies. These treatments induced papillomatosis in HPV8-CER and -E6 mice within 3 weeks. Irradiation with UVA alone did not induce papillomatosis and UVB alone had a weaker effect than UVA/UVB, indicating a synergistic role of UVA in UVB-induced papillomatosis. An HPV8 infection persisting over decades in interaction with sun burns and wound healing processes may be a relevant cause of skin cancer in humans.

Abstract
Infections by human papillomaviruses (HPVs) are the most frequently occurring sexually transmitted diseases. The crucial role of genital oncogenic HPV in cervical carcinoma development is now well established. In contrast, the role of cutaneous HPV in skin cancer development remains a matter of debate. Cutaneous beta-HPV strains show an amazing ubiquity. The fact that a few oncogenic genotypes cause cancers in patients suffering from epidermodysplasia verruciformis is in sharp contrast to the unapparent course of infection in the general population. Our recent investigations revealed that a natural barrier exists in humans, which protects them against infection with these papillomaviruses. A central role in the function of this HPV-specific barrier is played by a complex of the zinc-transporting proteins EVER1, EVER2, and ZnT-1, which maintain cellular zinc homeostasis. Apparently, the deregulation of the cellular zinc balance emerges as an important step in the life cycles not only of cutaneous but also of genital HPVs, although the latter viruses have developed a mechanism by which they can break the barrier and impose a zinc imbalance. Herein, we present a previously unpublished list of the cellular partners of EVER proteins, which points to future directions concerning investigations of the mechanisms of action of the EVER/ZnT-1 complex. We also present a general overview of the pathogenesis of HPV infections, taking into account the latest discoveries regarding the role of cellular zinc homeostasis in the HPV life cycle. We propose a potential model for the mechanism of function of the anti-HPV barrier.

Abstract
Evidence of a possible association of cutaneous human papillomavirus (HPV) types, especially members of the genus Betapapillomavirus, and the development of non-melanoma skin cancer (NMSC) is accumulating. Vaccination with virus-like particles (VLPs) consisting of self-assembled L1, the major capsid protein, has been introduced to control anogenital HPV infection. This study examined the serological relationship between betapapillomavirus (beta-PV) types 5 and 8 and the new type HPV-92, which has recently been isolated from a basal cell carcinoma containing a high number of viral genomes. Following expression by recombinant baculoviruses, the L1 protein of HPV-92 self-assembled into VLPs that elicited high-titre antibodies after immunization, similar to VLPs from HPV-5 and -8. Haemagglutination inhibition (HAI) assays were used as a surrogate method for the detection of virion-neutralizing antibodies, which correlates with protection from infection. Antisera raised against HPV-5 and -8 VLPs displayed HAI activity not only against the homologous type, but also against heterologous HPV types 5, 8 and 92, whereas HAI activity of antisera against HPV-92 VLP was restricted to the homologous type. The results of neutralization assays using HPV-5 pseudovirions were consistent with those from HAI assays. Cross-neutralizing immune responses by VLP vaccination against heterologous HPV types may provide broader protection against the multiplicity of HPV types detected in NMSC. If a close link to HPV infection can be conclusively established, these results may provide a basis for further evaluation of VLPs of beta-PVs as candidates for a prophylactic skin-type HPV vaccine, aimed at reducing the incidence of NMSC.

Abstract
Human papillomaviruses (HPV) are found in almost all squamous epithelia where they can cause hyperproliferative disease of mucosa and skin. Mucosal HPV types, such as HPV6 and HPV16, are known to cause anogenital warts and dysplasia or neoplasia, respectively. These HPV types have been studied extensively, and for some of them recently preventive vaccines have become available. Although HPV that populate the skin were the first identified HPV types, knowledge of the pathogenicity of HPV in the cornified epithelia stayed behind. What the majority of cutaneous HPV types do, for instance those belonging to the beta genus (betaPV), is largely unknown. As the number of reports that describe epidemiological associations between markers of betaPV infection and skin cancer gradually increases, the need for basic knowledge about these viruses grows as well. This review aims to picture what is currently known about betaPV with respect to infection, transmission and transformation, in order to envisage their potential role in cutaneous carcinogenesis.

Abstract
BACKGROUND We investigated the role of infection with genital and cutaneous human papillomavirus types (HPV) in the aetiology of ocular surface squamous neoplasia (which includes both conjunctival intraepithelial neoplasia (CIN) and carcinoma) using data and biological material collected as part of a case-control study in Uganda. RESULTS Among 81 cases, the prevalence of genital and cutaneous HPV types in tumour tissue did not differ significantly by histological grade of the lesion. The prevalence of genital HPV types did not differ significantly between cases and controls (both 38%; Odds ratio [OR] 1.0, 95% confidence interval [CI] 0.4-2.7, p = 1.0). The prevalence of cutaneous HPV types was 22% (18/81) among cases and 3% (1/29) among controls (OR 8.0, 95% CI 1.0-169, p = 0.04). CONCLUSION We find no evidence of an association between genital HPV types and ocular surface squamous neoplasia. The prevalence of cutaneous HPV was significantly higher among cases as compared to controls. Although consistent with results from two other case-control studies, the relatively low prevalence of cutaneous HPV types among cases (which does not differ by histological grade of tumour) indicates that there remains considerable uncertainty about a role for cutaneous HPV in the aetiology of this tumour.

Abstract
BACKGROUND Human papillomaviruses (HPVs) of the beta genus (beta-PV), especially HPV5 and HPV36, are proposed to play a pathogenic role in psoriasis, but many previous studies have failed to control for potential confounders, including treatment. OBJECTIVES To re-examine the relationship between beta-PV and psoriasis addressing limitations present in previous studies and analyse intra-patient concordance for carriage of HPV. METHODS Plucked eyebrow hairs and forearm skin scrapes were collected from 20 newly diagnosed, previously untreated adult patients with psoriasis and 23 normal controls. A combination of type-specific and degenerate polymerase chain reaction methods was used to achieve comprehensive HPV DNA detection. RESULTS The prevalence of HPV in hair and skin from psoriasis patients was higher than in controls (83.3% vs. 46.7%, respectively, P < 0.03 corrected for age and clustering). HPV5 or HPV36 were not over-represented. The profile of diverse beta-PV types was comparable in the two groups. Intra-patient concordance for HPV DNA at separate sites was high (P < 0.00001). CONCLUSIONS Our data do not support a specific causal role for HPV5 or HPV36 in psoriasis, but suggest that psoriatic skin may be more permissive for viral presence than normal skin. High intra-patient concordance for specific HPV types at separate sites, together with the ubiquity of HPV DNA in normal human skin, suggests that an individual becomes colonized with a particular beta-PV profile presumably to the exclusion of other types. To what extent this HPV profile is then causal in the subsequent development of hyperproliferative skin disease is unknown.

Abstract
The natural history of infections with many human papillomavirus (HPV) types is poorly understood. Here, we describe for the first time the age- and sex-dependent antibody prevalence for 29 cutaneous and five mucosal HPV types from 15 species within five phylogenetic genera (alpha, beta, gamma, mu, nu) in a general population. Sera from 1,797 German adults and children (758 males and 1,039 females) between 1 and 82 years (median 37 years) were analysed for antibodies to the major capsid protein L1 by Luminex-based multiplex serology. The first substantial HPV antibody reactions observed already in children and young adults are those to cutaneous types of the genera nu (HPV 41) and mu (HPV 1, 63). The antibody prevalence to mucosal high-risk types, most prominently HPV 16, was elevated after puberty in women but not in men and peaked between 25 and 34 years. Antibodies to beta and gamma papillomaviruses (PV) were rare in children and increased homogeneously with age, with prevalence peaks at 40 and 60 years in women and 50 and 70 years in men. Antibodies to cutaneous alpha PV showed a heterogeneous age distribution. In summary, these data suggest three major seroprevalence patterns for HPV of phylogenetically distinct genera: antibodies to mu and nu skin PV appear early in life, those to mucosal alpha PV in women after puberty, and antibodies to beta as well as to gamma skin PV accumulate later in life.

Abstract
Cutaneous human papillomaviruses (HPV) are common in nonmelanoma skin cancers, benign skin lesions, and healthy skin. Increased seroprevalences for cutaneous HPV among nonmelanoma skin cancer patients have been described. To determine whether antibodies to cutaneous HPV are related to presence of the virus and/or to skin disease, we collected serum and biopsies from both lesions and healthy skin from 434 nonimmunosuppressed patients (72 squamous cell carcinomas, 160 basal cell carcinomas, 81 actinic keratoses, and 121 benign lesions). Biopsies were analyzed for HPV DNA by PCR, cloning, and sequencing. Serum antibodies to the major capsid protein L1 of HPV 1, 5, 6, 8, 9, 10, 15, 16, 20, 24, 32, 36, 38, and 57 as well as to the oncoproteins E6 and E7 of HPV 8 and 38 were detected using a multiplexed fluorescent bead-based assay. Type-specific seroprevalence among patients with the same type of HPV DNA (sensitivity of serology) varied from 0% to at most 28%. Presence of HPV DNA and antibodies to the same HPV type was not significantly correlated. However, seropositivity to any HPV type was significantly more common among patients positive for HPV DNA of any HPV type (odds ratio, 1.90; 95% confidence interval, 1.55-2.34). Seroprevalences were similar among the different patient groups but was, for most HPV types, somewhat higher among squamous cell carcinoma patients than among basal cell carcinoma patients (P < 0.01). In conclusion, additional studies are required to clarify the biological meaning of seropositivity as a marker of cutaneous HPV infection and skin disease.

Abstract
Epidermodysplasia verruciformis (EV) is a genodermatosis associated with skin cancers that results from a selective susceptibility to related human papillomaviruses (EV HPV). Invalidating mutations in either of two genes (EVER1 and EVER2) with unknown functions cause most EV cases. We report that EVER1 and EVER2 proteins form a complex and interact with the zinc transporter 1 (ZnT-1), as shown by yeast two-hybrid screening, GST pull-down, and immunoprecipitation experiments. In keratinocytes, EVER and ZnT-1 proteins do not influence intracellular zinc concentration, but do affect intracellular zinc distribution. EVER2 was found to inhibit free zinc influx to nucleoli. Keratinocytes with a mutated EVER2 grew faster than wild-type keratinocytes. In transiently and stably transfected HaCaT cells, EVER and ZnT-1 down-regulated transcription factors stimulated by zinc (MTF-1) or cytokines (c-Jun and Elk), as detected with luciferase assays. To get some insight into the control of EV HPV infection, we searched for interaction between EVER and ZnT-1 and oncoproteins of cutaneous (HPV5) and genital (HPV16) genotypes. HPV16 E5 protein binds to EVER and ZnT-1 and blocks their negative regulation. The lack of a functional E5 protein encoded by EV HPV genome may account for host restriction of these viruses.

Abstract
Bovine papillomavirus (BPV), the causative agent of papillomas in cattle, has been shown to play a major role in the pathogenesis of equine sarcoids in horses. BPV has also been detected occasionally in normal equine skin. In this study, presence and activity of BPV in normal skin and peripheral blood of 4 groups of horses were evaluated: sarcoid-affected horses, horses living in contact with sarcoid-affected horses, horses living in contact with papilloma-affected cattle and control horses. From each horse, 3 samples on 4 locations were collected: a swab of the intact skin surface and both a swab and a biopsy after decontamination. BPV DNA was found in the normal skin of 24 of 42 horses (57%). Mainly sarcoid-affected horses and horses living in contact with cattle were carriers (73%), but BPV DNA was also detected in 50% of the horses living in contact with sarcoid-affected horses and in 30% of the control population. BPV mRNA was detected in 58% of the samples positive for BPV DNA, although in a much lower quantity compared to sarcoids. In most of the BPV DNA positive samples mild acanthosis, slight basophilic cytoplasmic swelling of the epidermal layers and/or thickening of the basal membrane were noticed, but these observations were also present in several BPV DNA negative normal skin samples. BPV DNA could not be detected in peripheral blood. These findings suggest latent infection and a wide-spread occurrence of BPV in the horse population.

While both variants and types of human papillomavirus (HPV) are common, subtypes (2-10% sequence divergence in the L1 gene) have been considered to be rare. We searched GenBank and in-house databases using a 440 nt L1 fragment and identified 7, 30 and 10 subtypes/putative subtypes in the HPV genera Alpha, Beta and Gamma, respectively. The number of types/putative types in each genus was 54, 58 and 103. Thus, there appears to exist at least 47 different subtypes/putative subtypes of HPV and they seem to be particularly common in the genus Beta-papillomavirus.

Abstract
In a prospective pilot study nested in the EPIC-Oxford cohort, we examined the seroprevalence of antibodies against the L1 antigen of 38 human papilloma virus (HPV) types among 39 cases of cutaneous squamous cell carcinoma (SCC) for whom plasma was collected prior to diagnosis (incident) and 80 controls. Fifteen cases having already developed SCC at blood collection (prevalent) were also tested. There were no statistically significant differences in the seroprevalence of antibodies against any of the HPV types examined between incident cases and controls, nor was there a difference in the seroprevalence of multiple infections. However, consistent with results from published case-control studies, the seroprevalence of many beta-HPV types was higher among prevalent cases than among either incident cases or controls. For example the seroprevalence of antibodies against HPV-8 was 20% (16/80) in controls, 23% (9/39) among incident cases and 40% (6/15) among prevalent cases. Among the incident cases only, the seroprevalence was 16% (5/32) among those for whom blood was collected 18+ months prior to diagnosis, but 57% (4/7) among those for whom diagnosis was within 18 months of blood collection, a pattern seen for many of the HPV types. This might suggest that if HPV is involved in the aetiology of SCC, the process occurs close to the time of diagnosis, or that the antibody response observed in people with SCC is a consequence of tumor formation. Further and larger prospective studies are needed to clarify the role of HPV in the aetiology of cutaneous SCC.

Abstract
Epidermodysplasia verruciformis (EV) is a rare autosomal recessive genodermatosis associated with a high risk of skin carcinoma. EV results from an abnormal susceptibility to infection by specific human papillomavirus (HPV) genotypes (beta-papillomaviruses) which include the potentially oncogenic HPV5. EV-specific HPVs are considered as harmless for the general population. EV was recently found to be caused by invalidating mutations in two adjacent, related, novel genes, EVER1/TMC6 and EVER2/TMC8. EVER genes encode transmembrane proteins located in the endoplasmic reticulum, which are likely to function as modifiers of ion transporters or channels and to be involved in signal transduction. It was proposed that EV was a primary defect of innate immunity. Our hypothesis is that EVER proteins act as restriction factors for EV-specific HPVs in keratinocytes, and that EV represents a primary deficiency of intrinsic immunity against certain papillomaviruses.

Abstract
The human papillomaviruses (HPVs) exist as more than 100 distinct types. While variants of HPV are common, only few HPV subtypes have been reported. HPV type 38 has been proposed to be associated with nonmelanoma skin cancer (NMSC), with reported prevalences of up to 55%. A subtype of HPV38 was cloned, completely sequenced and found to have a 96% sequence similarity to prototype HPV38 in the L1 open reading frame. The presence of prototype HPV38 and HPV38b[FA125] was examined in paired biopsies of tape-stripped skin lesions and healthy skin from 269 immunocompetent patients by real-time PCR. Prototype HPV38 and HPV38b[FA125] were present in seven (3%) and five (2%) lesions, respectively, in viral loads ranging from one copy per 150 cells to one copy per 70,000 cells. In summary, we found that HPV38 is heterogeneous and is one of so far only few HPVs that contain subtypes. The heterogeneity needs to be considered in studies of the biology of this virus.

Abstract
The cottontail rabbit papillomavirus (CRPV) a and b subtypes display a conserved E8 open reading frame encoding a 50-amino-acid hydrophobic protein, with structural similarities to the E5 transmembrane oncoprotein of genital human PVs (HPVs). CRPV E8 has been reported to play a role in papilloma growth but not to be essential in papilloma formation. Here we report that the knockout of E8 start codon almost prevented wart induction upon biobalistic inoculation of viral DNA onto rabbit skin. The scarce warts induced showed very slow growth, despite sustained expression of E6 and E7 oncogenes. This points to an essential role of E8 in disturbing epidermal homeostasis. Using a yeast two-hybrid screen, we found that E8 interacted with the zinc transporter ZnT1, protocadherin 1 (PCDH1), and AHNAK/desmoyokin, three proteins as yet unrelated to viral pathogenesis or cell transformation. HPV16 E5 also interacted with these proteins in two-hybrid assay. CRPV E8 mainly localized to the Golgi apparatus and the early endosomes of transfected keratinocytes and colocalized with ZnT1, PCDH1, and AHNAK. We showed that ZnT1 and PCDH1 formed a complex and that E8 disrupted this complex. CRPV E8, like HPV16 E5, increased epidermal growth factor (EGF)-dependent extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation and both the EGF-dependent and the EGF-independent activity of activating protein-1 (AP-1). Competition experiments with a nonfunctional truncated ZnT1 protein showed that E8-ZnT1 interaction was required for AP-1 activation. Our data identify CRPV E8 as a key player in papilloma induction and unravel novel cellular targets for inducing the proliferation of keratinocytes.

Abstract
Human papilloma virus type 5 (HPV-5) has been associated closely with psoriatic skin in Polish patients, while findings from other countries have indicated a more limited prevalence. The results of the present study, in which a type-specific nested PCR was used, indicated that scales of plaque-type psoriatic skin from 54 Italian patients had a high prevalence (74.1%) of HPV-5 DNA in lesional areas, and a reduced prevalence (33.3%) in non-lesional skin (33.3%), compared to 0% of 20 healthy subjects and 3.6% in the lesional areas of 28 patients with various other dermatological diseases. Individuals negative for HPV-5 DNA had a less severe disease. No correlation was found between the presence of HPV DNA and a patient's age or sex. The data demonstrated a statistically significant association between psoriasis and HPV-5, although results in other geographical areas suggest variable virus spread or ethnic variation in virus colonisation.

Abstract
Cutaneous epidermodysplasia verruciformis (EV)-associated human papillomaviruses (HPVs) are found frequently in skin cancers especially in immunosuppressed people. They are also detectable in the normal skin and hair follicles of a proportion of individuals who have no immune defect. The available evidence to link HPVs causally with skin carcinogenesis is not conclusive, but includes epidemiological, molecular and immunological studies.

Abstract
BACKGROUND The relation between human papillomavirus (HPV) and extragenital Bowen's disease (BD) is controversial. METHODS This study used in situ hybridisation to evaluate the rate of HPV in extragenital cutaneous BD and investigated possible relations with immune status and exposure of skin to light. RESULTS HPV DNA was detected in 58% of 69 samples from 50 patients. The percentage of HPV detection was not significantly higher in exposed (55%) than unexposed areas (65%), and no difference in HPV rate was found between immunosuppressed and immunocompetent patients. CONCLUSION Thus, this study confirms the high rate of HPV detection in extragenital cutaneous BD and suggests that there is no apparent relation concerning exposed areas and immune status.

Abstract
Papillomavirus was identified in pigmented epidermal plaques (PEP) from three dogs: a miniature schnauzer with hyperadrenocorticism and hypoglobulinemia, an American Staffordshire terrier with hypoglobulinemia, and a Pomeranian with unconfirmed hypothyroidism. Squamous cell carcinoma (SCC) arose within several plaques in the Pomeranian. Clinical improvement coincided in the first two cases with treatment of the concurrent disease and the administration of low-dose oral interferon-α. This is the first report of PEP in an American Staffordshire terrier and a Pomeranian. The potential for malignant transformation of PEP to SCC emphasizes the need for recognition and clinical management of PEP.

Abstract
We have shown previously in psoriasis a very high prevalence of epidermodysplasia verruciforms-associated human papillomavirus 5 (EVHPV5) DNA and antibodies to human papillomavirus 5 (HPV5) virus-like particle (VLP) L1, and we suggested that this benign hyperproliferative disorder could be a reservoir for EVHPVs. Here we provide new data confirming the expression of EVHPVs in psoriasis and present our hypothesis on their possible involvement in the immunopathogenesis of the disorder. The new important finding was detection by radioimmunoprecipitation assay of a very high prevalence of antibodies to E6/E7 HPV5 oncoproteins, known to enhance keratinocyte proliferation. More recently, EV genes were identified, EVER1 and EVER2, whose mutations are responsible for epidermodysplasia verruciformis. Eidermodysplasia verruciforms-associated human papillomaviruses are harmless to the general population as a result of genetic restriction, which in psoriasis appears to be partly alleviated, and this may allow the viral gene expression. We hypothesize that induction of keratinocyte proliferation in psoriasis by various stimuli initiates the EVHPV life cycle with expression of early (E6/E7) and late (L1) viral proteins. The early proteins may, in turn, enhance the keratinocyte proliferation, and the late proteins could serve as target for specific-B- and T-cell-mediated responses. Immune responses against the viral antigens in the epidermis may result in the chemoattraction of leukocytes and Munro abscess formation, as well as in production of the psoriatic process. The novel immunomodulatory therapies could also inhibit immune responses against EVHPV proteins, leading to decreased cytokine production, keratinocyte proliferation and EVHPV expression. Thus the beneficial effect of these therapies is not discordant with the propose hypothesis of possible involvement of EVHPVs in the immunopathogenesis of psoriasis.

Abstract
PURPOSE OF REVIEW The human papillomavirus is a ubiquitous 55-nm DNA virus that causes a variety of clinical disease states in children, commonly referred to as warts. The natural history of warts is spontaneous regression through the development of a complex blend of cell-mediated and humoral immunity. Although spontaneous immunity can develop, as many as one third of children will have persistent human papillomavirus infection beyond 2 years. Therapeutic modalities are manifold, primarily because no therapy is universally effective. The purpose of this review is to update the reader with the latest information on the human papillomavirus and its therapeutics in children. RECENT FINDINGS Recently, encouraging research has been conducted in human papillomavirus, including destructive and immunologic therapies. Vaccines tailored to genital human papillomavirus strains are just coming into clinical use. SUMMARY Manipulation of the immune system through medications or vaccination will likely help contain human papillomavirus in the future and prevent secondary human papillomavirus oncogenesis of the skin and cervix.

Abstract
Ultraviolet radiation (UVR) is associated with an increased risk of squamous cell carcinoma (SCC), which is in part due to immunomodulation. In addition, human papilloma virus (HPV), especially the epidermodysplasia verruciformis (EV)-associated types, may be involved. In view of the capacity of UVR to impair host resistance to infections, we investigated the relationship between solar exposure and the prevalence of cutaneous HPV. In a case-control study on skin cancer (320 controls and 156 patients) a lifetime-retrospective questionnaire on sun exposure was administered. The presence of DNA of HPV types 5, 8, 15, 20, 24, and 38 in plucked eyebrow hair and type-specific seroreactivity were assessed and analyzed in relation to estimated exposure. Sunburn episodes in the past, especially at age 13-20 y, appeared to be associated with an enhanced risk of EV-HPV DNA positivity. In contrast, a higher lifetime sun exposure was associated with a lower risk of HPV infection. These results indicate that UVR at erythematogenic doses increases the risk of EV-HPV infection, possibly due to impaired host resistance to HPV and/or a direct effect of UVR on viral replication. The favorable association between lifetime sun exposure and HPV prevalence, however, underscores the enigmatic role of HPV in skin carcinogenesis.

Abstract
BACKGROUND Human papillomaviruses (HPVs) are found in normal skin and in benign and malignant skin conditions. Epidermodysplasia verruciformis (EV) HPV types are those most plausibly linked to the development of squamous cell carcinomas of the skin. OBJECTIVES To assess the risk of nonmelanoma skin cancer (NMSC) associated with the presence of EV HPV in normal skin in immunocompetent (IC) individuals and renal transplant recipients (RTRs). METHODS Using a degenerate and nested polymerase chain reaction technique, HPV DNA was sought in 124 normal skin samples from sun-exposed and nonsun-exposed sites, from 39 IC individuals and 38 RTRs, both with and without NMSC. Data were analysed using the Mantel-Haenszel test and by logistic regression analysis. RESULTS HPV DNA was detected in 58/67 (87%) and 20/57 (35%) samples from renal transplant and IC patients, respectively. There was no difference in either the prevalence or spectrum of HPV types found in sun-exposed and nonsun-exposed normal skin. However, there was significant association between NMSC and the presence of EV HPV DNA. Multivariate analysis provided an odds ratio of 6.41 (95% confidence interval 1.79-22.9) for the association of EV HPV DNA in normal skin (irrespective of site) and NMSC status, even after stratifying for patient group and adjusting for the clustering effect of multiple sampling. Conversely, there was no association between skin cancer status and the presence of cutaneous or mucosal HPV types in either sun-exposed or nonsun-exposed skin. CONCLUSIONS HPV DNA is widespread in normal adult skin, particularly in transplant patients. In our study, the presence of EV but not cutaneous HPV DNA in normal skin was significantly associated with NMSC status and may prove to be of predictive value for skin cancer risk. These data provide reason to focus on EV HPV types as causal agents in skin cancer.
