Abstract
Langya Henipavirus (LayV) infection is an emerging zoonotic disease that has been causing respiratory symptoms in China since 2019. For virus entry, LayV's genome encodes the fusion protein F and the attachment glycoprotein G. However, the structural and functional information regarding LayV-G remains unclear. In this study, we revealed that LayV-G cannot bind to the receptors found in other HNVs, such as ephrin B2/B3, and it shows different antigenicity from HeV-G and NiV-G. Furthermore, we determined the near full-length structure of LayV-G, which displays a distinct mushroom-shaped configuration, distinguishing it from other attachment glycoproteins of HNV. The stalk and transmembrane regions resemble the stem and root of mushroom and four downward-tilted head domains as mushroom cap potentially interact with the F protein and influence membrane fusion process. Our findings enhance the understanding of emerging HNVs that cause human diseases through zoonotic transmission and provide implication for LayV related vaccine development.

[PMID: 38282399 DOI: 10.1002/rmv.2520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 01/16/2024] [Accepted: 01/17/2024] [Indexed: 01/30/2024]
Abstract
First reported in August 2022, the Langya virus (LayV) has emerged as a potential global health threat in the post-COVID-19 era. Preliminary reports show that 35 patients near Shandong and Henan, China experienced a febrile acute LayV infection. We conducted this review following the PRISMA protocol to synthesise current knowledge on LayV's characteristics in terms of molecular, clinical, and public health perspectives. This virus belongs to the Paramyxoviridae family and carries a non-segmented, single-stranded negative-sense RNA genome. Shrews may be the natural reservoir of the virus. Clinical symptoms range from mild flu-like symptoms to severe manifestations involving pneumonia, haematological disorders, and organ dysfunction. Diagnostic methods include PCR and ELISA assays. Despite the absence of established treatments, antiviral drugs such as ribavirin and chloroquine may be useful in some cases. In light of prevention, a comprehensive approach that emphasises multidisciplinary collaboration is crucial for early surveillance and response. Urgent global efforts are needed for vaccine development and preparedness against this potential pandemic threat. As the viral dynamics remain uncertain, a proactive approach is vital to mitigate the impact of not only LayV but also future threats on a large scale in long term.
