A potential broad‐spectrum neutralizing antibody against Betacoronavirus

open access: yesJournal of Medical Virology, 2023
Three pandemics caused by human Betacoronavirus had broken out in the past two decades. Severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) was one of the novel epidemic strains which caused the third pandemic, coronavirus disease 2019 (COVID‐19)

Loading of Oregano Oil in Natural Nanogel and Preliminary Studies on Its Antiviral Activity on Betacoronavirus 1. [PDF]

open access: yesMolecules
Oregano oil was successfully encapsulated into chitosan–albumin nanogel via emulsification and electrostatic gelation. The system was characterized with a mean diameter around 26 nm, narrow size distribution (PDI = 0.242) and approximately 40 ...

Pre-pandemic artificial MERS analog of polyfunctional SARS-CoV-2 S1/S2 furin cleavage site domain is unique among spike proteins of genus Betacoronavirus. [PDF]

open access: yesBMC Genom Data
SARS-CoV-2 spike (S) glycoprotein furin cleavage site is a key determinant of SARS-CoV-2 virulence and COVID-19 pathogencity. Located at the S1/S2 junction, it is unique among sarbecoviruses but frequently found among betacoronaviruses.

Discovery and characterization of a pan-betacoronavirus S2-binding antibody.

open access: yesStructure
Three coronaviruses have spilled over from animal reservoirs into the human population and caused deadly epidemics or pandemics. The continued emergence of coronaviruses highlights the need for pan-coronavirus interventions for effective pandemic ...

Betacoronavirus Infection Outbreak, São Paulo, Brazil, Fall 2023

open access: yesEmerging Infectious Diseases
We report a human coronavirus OC43 infection outbreak in hospitalized patients and healthcare workers in São Paulo, Brazil, occurring after SARS-CoV-2 cases disappeared. Infection was associated with healthcare workers in 5 (29.4%) patients.

Detection of avian, murine, bovine, shrew, and bat coronaviruses in wild mammals from Mexico [PDF]

open access: yesVirology Journal
Coronaviruses infect a wide range of animal and human hosts. Some human coronaviruses, such as SARS-CoV, MERS-CoV, and SARS-CoV-2, originated in animals, with bats often serving as ancestral hosts.

DNA vaccine targeting betacoronavirus spike protein blocks neuroinvasion and neuroinflammation in swine via dual antiviral-immunomodulatory action. [PDF]

open access: yesNPJ Vaccines
Porcine hemagglutinating encephalomyelitis virus (PHEV), a neurotropic betacoronavirus, causes fatal neurological disease in piglets, yet no licensed vaccines exist.

E3 Ubiquitin Ligase Smurf1 Regulates the Inflammatory Response in Macrophages and Attenuates Hepatic Damage during Betacoronavirus Infection. [PDF]

open access: yesPathogens
The E3 ubiquitin ligase Smurf1 catalyzes the ubiquitination and proteasomal degradation of several protein substrates related to inflammatory responses and antiviral signaling. This study investigated the role of Smurf1 in modulating inflammation induced

Crystal structure of the membrane (M) protein from a bat betacoronavirus

open access: yesPNAS Nexus, 2023
The membrane (M) protein is the most abundant structural protein of coronaviruses including MERS-CoV, SARS-CoV, and SARS-CoV-2, and plays a central role in virus assembly through its interaction with various partner proteins. However, mechanistic details
