背景信息

Kaposi's sarcoma-associated herpesvirus (KSHV), a gammaherpesvirus linked to several malignancies, encodes ORF45 as an immediate-early protein critical for viral pathogenesis. ORF45 plays multifaceted roles in immune evasion by antagonizing interferon regulatory factor 7 (IRF7)-mediated antiviral responses and enhancing viral replication. It also interacts with cellular kinases to modulate host signaling pathways. Antibodies targeting KSHV ORF45 are essential tools for studying its expression, localization, and function during viral infection. These antibodies enable detection of ORF45 in infected cells via techniques like Western blot, immunofluorescence, and immunohistochemistry, aiding research on viral lifecycle stages and host-pathogen interactions. Due to ORF45's low abundance and transient expression, developing specific antibodies requires careful antigen design, often using recombinant protein fragments or synthetic peptides. Validated ORF45 antibodies help dissect mechanisms of KSHV-mediated oncogenesis, immune suppression, and latency-reactivating strategies. They also contribute to diagnostic assays for KSHV-associated diseases, including Kaposi's sarcoma and primary effusion lymphoma. Recent studies further utilize these antibodies to explore ORF45's role in exosome-mediated viral spread and its potential as a therapeutic target.
