Pasteur’s work on fermentations has variously influenced the conception that veterinarians had of the origin of virulent diseases. Jean-Baptiste Chauveau asserted as early as 1866 the specificity of contagious diseases and their exogenous origin. Henri Bouley was initially a supporter of the spontaneity of these diseases. He became an advocate of t...
We study a patient with the human papilloma virus (HPV)-2-driven “tree-man” phenotype and two relatives with unusually severe HPV4-driven warts. The giant horns form an HPV-2-driven multifocal benign epithelial tumor overexpressing viral oncogenes in the epidermis basal layer. The patients are unexpectedly homozygous for a private CD28 variant. The...
Significance
Recurrent respiratory papillomatosis is a disease caused by the human papillomavirus that leads to growth of warts in the throat. We report 2 brothers with a form of this disease that involves a mutation in the NLRP1 gene. This study provides a genetic explanation for our patients’ disease and suggests that other people may suffer from...
Patients with epidermodysplasia verruciformis (EV) and biallelic null mutations of TMC6 (encoding EVER1) or TMC8 (EVER2) are selectively prone to disseminated skin lesions due to keratinocyte-tropic human β-papillomaviruses (β-HPVs), which lack E5 and E8. We describe EV patients homozygous for null mutations of the CIB1 gene encoding calcium- and i...
Epidermodysplasia verruciformis (EV) is an autosomal recessive skin disorder with a phenotype conditional on human beta-papillomavirus (beta-HPV) infection. Such infections are common and asymptomatic in the general population, but in individuals with EV, they lead to the development of plane wart-like and red or brownish papules or pityriasis vers...
Epidermodysplasia verruciformis (EV) is characterized by persistent cutaneous lesions caused by a specific group of related human papillomavirus genotypes (EV-HPVs) in otherwise healthy individuals. Autosomal recessive (AR) EVER1 and EVER2 deficiencies account for two thirds of known cases of EV. AR RHOH deficiency has recently been described in tw...

Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by persistent flat warts or pityriasis versicolor-like lesions caused by betapapillomaviruses (EV-HPVs). Autosomal recessive EVER1 and EVER2 deficiencies account for EV in most patients. The mechanisms by which mutations in these partners of the Zinc transporter ZnT1 impair...
Epidermodysplasia verruciformis (EV) is a rare genetic disorder characterized by increased susceptibility to specific human papillomaviruses, the betapapillomaviruses. These EV-HPVs cause warts and increase the risk of skin carcinomas in otherwise healthy individuals. Inactivating mutations in epidermodysplasia verruciformis 1 (EVER1) or EVER2 have...
The outcomes of infection by human papillomaviruses (HPV), both oncogenic and non oncogenic, show major interindividual variability The underlying genetic factors and mechanisms are poorly known, but their complexity is illustrated by epidermodysplasia verruciformis (EV), a rare autosomal recessive genodermatosis associated with a high risk of non...
Human papillomaviruses (HPVs) constitute a large and highly heterogeneous group of over 100 genotypes distributed in 25 species and five genera of the family Papillomaviridae. Their small, nonenveloped, icosahedral capsid contains a double-stranded, covalently closed, circular DNA molecule of 7500–8000 bp. The viral genome is divided into a noncodi...
Epidermodysplasia verruciformis (EV) is a rare, autosomal recessive genodermatosis associated with a high risk of skin carcinoma (MIM 226400). EV is characterized by the abnormal susceptibility of otherwise healthy patients to infection by specific, weakly virulent human papillomaviruses (HPVs), including the potentially oncogenic HPV-5. Inactivati...
Epithelial tumours of the lacrimal sac are rare but important entities that may carry grave prognoses. In this study the prevalence and possible role of human papillomavirus (HPV) infection in epithelial tumours of the lacrimal sac were evaluated.
Five papillomas and six carcinomas of the lacrimal sac were investigated for the presence of HPV using...
We identified sequences from two distantly related papillomaviruses in genital warts from two Burmeister's porpoises, including a PV antigen-positive specimen, and characterized Phocoena spinipinnis papillomavirus type 1 (PsPV-1). The PsPV-1 genome comprises 7879 nt and presents unusual features. It lacks an E7, an E8 and a bona fide E5 open readin...
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 fo...
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...

This study was undertaken to investigate the impact of highly active antiretroviral therapy (HAART) on the regression of cervical intraepithelial neoplasia (CIN) in HIV-infected women.
Prospective study of 168 HIV-infected women with evidence of CIN until regression to a lower grade or to normality (end-point) or until surgical treatment or last vi...
Patients suffering from epidermodysplasia verruciformis are prone to nonmelanoma skin cancers, due to an inherited abnormal susceptibility to the oncogenic human papillomavirus type 5. Genotoxic sunlight ultraviolet B radiations are likely to be a cofactor. Lesions of two human-papillomavirus-type-5-infected epidermodysplasia verruciformis patients...
In a very interesting and provocative article, Antonsson et al. reported a high prevalence of known or as-yet-uncharacterized human papillomavirus (HPV) genotypes on the healthy skin of immunosuppressed and immunocompetent individuals, as detected by a PCR approach (1). This demonstrates unambiguously the ubiquity and great multiplicity of cutaneou...
We previously reported the partial characterization of two cottontail rabbit papillomavirus (CRPV) subtypes with strikingly divergent E6 and E7 oncoproteins. We report now the complete nucleotide sequences of these subtypes, referred to as CRPVa4 (7,868 nucleotides) and CRPVb (7,867 nucleotides). The CRPVa4 and CRPVb genomes differed at 238 (3%) nu...
