VP35抗体

The Lloviu virus (LLOV) is a pathogenic filovirus identified in bat populations in southern Europe (1-3). It belongs to the Filoviridae family, members of which (e.g., Ebola, Marburg) are known to cause fatal hemorrhagic diseases in primates, including humans (4). Transcription and replication of filoviruses requires formation of a ribonucleoprotein (RNP) complex, composed of nucleoprotein (NP) together with viral polymerase enzymes and cofactors. Viral Protein 35 (VP35), a polymerase cofactor, is one of the key components of the RNP complex in filoviruses (5). In addition to its role in promoting viral replication, research studies in both bat and human cells have shown that Lloviu virus VP35 can suppress the host innate immune response to viral infection, in part through suppression of the interferon response (6). These immunosuppressive functions of Lloviu virus VP35 are consistent with those observed for VP35 homologs in other filovirus species (7,8).
