Article Abstract
Lassa fever virus (LASV) can cause life-threatening hemorrhagic fevers for which there are currently no vaccines or targeted treatments. The late Prof. Stefan Kunz, along with others, showed that the high-affinity host receptor for LASV, and other Old World and clade-C New World mammarenaviruses, is matriglycan-a linear repeating disaccharide of alternating xylose and glucuronic acid that is polymerized uniquely on α-dystroglycan by like-acetylglucosaminyltransferase-1 (LARGE1). Although α-dystroglycan is ubiquitously expressed, LASV preferentially infects vascular endothelia and professional phagocytic cells, which suggests that viral entry requires additional cell-specific factors. In this review, we highlight the work of Stefan Kunz detailing the molecular mechanism of LASV binding and discuss the requirements of receptors, such as tyrosine kinases, for internalization through apoptotic mimicry.

Lassa virus (LASV) is circulating in rodents in several countries in West Africa and is the causative agent of the zoonotic disease Lassa fever. Several vaccine candidates have been successfully tested in preclinical and clinical research, while no LASV-specific vaccines or antiviral treatments have been licensed to date. Approximately 500,000 human cases of Lassa fever are estimated to occur every year.

Sin Nombre virus (SNV) is the main causative agent of hantavirus cardiopulmonary syndrome (HCPS) in North America. SNV is transmitted via environmental biological aerosols (bioaerosols) produced by infected deer mice (). It is similar to other viruses that have environmental transmission routes rather than a person-to-person transmission route, such as avian influenza (e.

Background: Lassa fever is an acute viral haemorrhagic disease endemic to West Africa, with Nigeria, Sierra Leone, and Liberia bearing the greatest burden. Despite repeated outbreaks and rising incidence, a regional synthesis of epidemiologic indicators remains lacking. This systematic review and meta-analysis aimed to estimate pooled attack rates (proportion of a population affected during an outbreak), case fatality rates (CFRs), and identify consistent risk factors associated with Lassa fever in West Africa.

Lassa fever hemorrhagic virus (LFHV) outbreaks in Nigeria continue to increase. With the possibility of a potentially deadly pandemic and the absence of a vaccine, an effective candidate drug that presents with no adverse effects and better clinical outcomes is urgently needed; hence, the aim of the study. Retrieved ligands: 5-(Methylene) evodiamine, N-(2-Fluorobenzoyl) evodiamine, N-[[2-(3-chlorophenyl)-5-(trifluoromethyl) pyrazol-3-yl]methyl]-2-(1-methyl-2,3-dihydroindol-5-yl) propanamide (NCTPMMDP), lauric acid, and sofosbuvir, and the target protein, 3MX5, were prepared and utilised for docking, molecular dynamics simulation, ADMET profiling, and DFT using standard protocols.
