Description

Human herpesvirus type 8 (HHV-8) is the likely etiological agent of Kaposi’s sarcoma (KS). HHV-8 DNA sequences have been found in Kaposi’s sarcoma lesions, primary effusion lymphoma, and multicentric Castleman’s disease via polymerase chain reaction and in situ hybridization. Latent nuclear antigen (LNA-1, LNA, LANA-1), also known as ORF73, is a 222- or 234 kD protein that is consistently expressed in HHV-8 infected cells. Anti-HHV-8 labels the latent nuclear antigen protein via immunohistochemistry.
