- IFN-γ-inducible protein 16 (IFI16) is an immunological DNA sensor proposed to act in the cyclic GMP-AMP synthase-stimulator of IFN genes pathway. Because mice do not have a clear ortholog of IFI16, this system is not suitable for genetic studies of IFI16. In this study, we have compared the dependency on IFI16, cyclic GMP-AMP synthase, and stimulator of IFN genes for type I IFN induction by a panel of pathogenic bacteria and DNA viruses. The IFN response induced by HSV-2 was particularly dependent on IFI16. In a cohort of patients with genital herpes and healthy controls, the minor G allele of the IFI16 single nucleotide polymorphism rs2276404 was associated with resistance to infection. Furthermore, the combination of this allele with the C allele of rs1417806 was significantly overrepresented in uninfected individuals. Cells from individuals with the protective GC haplotype expressed higher levels of IFI16 and induced more IFN-β upon HSV-2 infection. These data provide genetic evidence for a role for IFI16 in protection against genital herpes.

- Lichen sclerosus is a chronic inflammatory disease associated with substantial morbidity. Knowledge of the aetiology and progression of lichen sclerosus is therefore needed. In this cross-sectional study, 100 male patients diagnosed with lichen sclerosus were interviewed and examined. Since there is a possible link between lichen sclerosus and autoimmunity, blood tests were analysed for thyroid disease, antinuclear antibodies and antibodies to extracellular matrix protein 1, but autoimmunity was found to be infrequent. In 72 participants active genital lichen sclerosis was observed and complications were common; 27 patients had preputial constriction and 12 meatal engagement. In total, 13 patients needed a referral to the Department of Urology, including 1 patient with suspected penile cancer. In conclusion, despite available treatment with ultra-potent steroids and circumcision, LS in males is frequently complicated by phimosis and meatal stenosis. However, the disease can also go into remission, as seen in 27% of our patients.
