  ABSTRACT Middle East respiratory syndrome coronavirus (MERS-CoV) causes a highly lethal respiratory infection for which no vaccines or antiviral therapeutics are currently available . Understanding the immune response is critical for designing effective therapeutics . Here, we comprehensively characterized the dynamics of B-cell responses in severely infected MERS-CoV patients and survivors with SARS-CoV-2 exposure history . Infected patients developed robust neutralizing antibody responses within 1 month of illness , with moderate-to-high cross-neutralization activity against SARS-CoV-2 . The enhanced neutralization activity coincided with an increased abundance of specific mutated, class-switched IgG clones. Notably, one such clone was detected at moderate prevalence in both patients, and its expansion was accompanied by high neutralization activity against both viruses . Conversely, MERS-CoV survivors demonstrated higher neutralization activity against MERS-CoV after vaccinati...

  Abstract SARS-CoV-2 rapidly adapts to new hosts following cross-species transmission; this is highly relevant as unique within-host variants have emerged following infection of susceptible wild and domestic animal species . Furthermore, SARS-CoV-2 transmission from animals (e.g., white-tailed deer, mink, domestic cats, and others) back to humans has been observed , documenting the potential of animal-derived variants to infect humans. Here, we investigate SARS-CoV-2 evolution and host-specific adaptation during an outbreak in Amur tigers (Panthera tigris altaica), African lions (Panthera leo), and spotted hyenas (Crocuta crocuta) at Denver Zoo in 2021 . SARS-CoV-2 genomes from longitudinal samples from 16 individuals are evaluated for within-host variation and genomic signatures of selection, and we determine that the outbreak was likely initiated by a single spillover of a rare Delta sublineage . Within-host virus populations rapidly expand and diversify, and we detect signature...

  ABSTRACT The secondary thrombotic/vascular clinical syndrome of COVID-19 suggests that SARS-CoV-2 infects the endothelium ; however, robust in vitro infection of endothelial cells by various strains of SARS-CoV-2 remains to be demonstrated and continues to be debated. Here, we revisit the question of endothelial cell permissiveness to SARS-CoV-2 using isolated endothelial cells ( from the lung, aorta, and endothelial cell progenitors ), and additionally, to overcome limitations associated with cultured cells , using native endothelial cells within living precision cut human lung slices and single-cell RNA sequencing to track viral presence. Cellular infection in endothelial monocultures was determined using fluorescence imaging. Mediator release was measured by ELISA, and gene expression was assessed by RT-qPCR. Infection in lung slices was determined using single-cell RNA sequencing, capturing molecular identifiers that aligned to the SARS-CoV-2 viral genome (for lung slices). E...

{Summary} Context   Over five years since the detection of the first COVID-19 cases , SARS-CoV-2 continues to circulate globally, causing acute illness, hospitalization, and death , alongside prolonged negative impacts on individuals, health systems , and economies , including post-COVID-19 condition (PCC or Long COVID).  While global population-level immunity has increased significantly through both infection and vaccination, the virus continues to evolve, challenging control efforts and underscoring the need for long-term, sustainable disease management .  Confirming earlier warnings from MERS-CoV and SARS-CoV-1 , SARS-CoV-2 has demonstrated the pandemic potential of coronaviruses , which remain one of the most consequential infectious disease threats of our time .  Purpose of the strategic plan   This plan sets out WHO’s strategic framework to support Member States in the sustained, integrated, evidence-based management of coronavirus disease threats , includ...

  ABSTRACT The evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in antigenically distinct variants that challenge vaccine-induced immunity. The KP.2 monovalent mRNA vaccine was deployed in 2024 to address immune escape by emerging SARS-CoV-2 subvariants . We assessed neutralizing antibody responses in 56 adults with varied exposure histories following KP.2 vaccination against emerging variants including LP.8.1, LF.7.1, NB.1.8.1, XFG, and BA.3.2 . While KP.2 vaccination enhanced neutralization against homologous variants, substantial reductions in neutralizing activity were observed against emerging Omicron variants across all exposure groups. Exposure history showed some influence on neutralization breadth , with self-reported vaccination-only participants exhibiting better cross-neutralization compared to individuals with hybrid immunity . Antigenic cartography revealed substantial antigenic distances between KP.2 and emerging variants, highli...

  Abstract The membrane (M) protein of coronaviruses is essential for maintaining structural integrity during membrane virion budding and viral pathogenesis . Given its high conservation in lineages within the betacoronavirus genus , such as sarbecoviruses , the M protein presents as an attractive therapeutic target ; however, developing broad-spectrum antivirals targeting coronaviruses such as MERS-CoV is challenging due to lower sequence conservation and limited structural information available beyond that of the SARS-CoV-2 M protein . In this study, we report 3-3.2 Å resolution structures of MERS-CoV M protein, engineered with a SARS-CoV-2-like antibody interface, representing the first human merbecovirus M protein structure , and SARS-CoV M protein structures, with and without a previously identified SARS-CoV-2 M protein inhibitor, JNJ-9676. We highlight the structural differences between the MERS-CoV, SARS-CoV and SARS-CoV-2 M proteins, and present insights into the conservati...
