ANKRD1 regulates innate immune responses against herpes simplex virus 1: A potential role in eczema herpeticum.

Atopic dermatitis (AD) is a common inflammatory skin disease. A subset of AD is susceptible to disseminated herpes simplex virus (HSV) infection, a complication termed as eczema herpeticum(ADEH+). The immune mechanisms causing ADEH+ remain elusive. Using RNA-sequencing, we recently found that ankyrin repeat domain 1 (ANKRD1) was significantly induced in human peripheral blood mononuclear cells (PBMCs) upon HSV-1 stimulation; and its induction in ADEH+ was significantly reduced as compared to AD patients without a history of EH (ADEH-).
