Antigenic Site-Specific Competitive Antibody Responses to the Fusion Protein of Respiratory Syncytial Virus Were Associated With Viral Clearance in Hematopoietic Cell Transplantation Adults.

Front Immunol 2019 29;10:706. Epub 2019 Mar 29.

Department of Molecular Virology and Microbiology, Baylor College of Medicine, Houston, TX, United States.

Recent studies of human sera showed that the majority of the respiratory syncytial virus (RSV) neutralizing antibodies are directed against pre-fusion conformation of the fusion (F) protein of RSV and revealed the importance of pre-fusion antigenic site Ø specific antibodies. However, detailed analysis of multiple antigenic site-specific competitive antibody responses to RSV F protein and their contribution to virus clearance in humans are lacking. We prospectively enrolled a cohort of RSV infected hematopoietic cell transplantation (HCT) adults ( = 40). Read More

Confined Polymers as Self-Avoiding Random Walks on Restricted Lattices.

Polymers (Basel) 2018 Dec 15;10(12). Epub 2018 Dec 15.

Institute for Optoelectronic Systems and Microtechnology (ISOM) and ETSI Industriales, Universidad Politécnica de Madrid, José Gutiérrez Abascal, 2, 28006 Madrid, Spain.

Polymers in highly confined geometries can display complex morphologies including ordered phases. A basic component of a theoretical analysis of their phase behavior in confined geometries is the knowledge of the number of possible single-chain conformations compatible with the geometrical restrictions and the established crystalline morphology. While the statistical properties of unrestricted self-avoiding random walks (SAWs) both on and off-lattice are very well known, the same is not true for SAWs in confined geometries. Read More

Association of Rhinovirus C Bronchiolitis and Immunoglobulin E Sensitization During Infancy With Development of Recurrent Wheeze.

JAMA Pediatr 2019 Apr 1. Epub 2019 Apr 1.

Department of Emergency Medicine, Massachusetts General Hospital, Harvard Medical School, Boston.

Importance: Rhinovirus infection in early life, particularly with allergic sensitization, is associated with higher risks of developing recurrent wheeze and asthma. While emerging evidence links different rhinovirus species (eg, rhinovirus C) to a higher severity of infection and asthma exacerbation, to our knowledge, little is known about longitudinal associations of rhinovirus C infection during infancy with subsequent morbidities.

Objective: To examine the association of different viruses (respiratory syncytial virus [RSV], rhinovirus species) in bronchiolitis with risks of developing recurrent wheeze. Read More

Laboratory of Vector Control Research, Unit Transmission Reservoir and Pathogen Diversity, Institute Pasteur of Guadeloupe, Les Abymes, Guadeloupe, France.

Zika virus (ZIKV), discovered in the Zika Forest of Uganda in 1947, is a mosquito-borne flavivirus related to yellow fever, dengue and West Nile viruses. From its discovery until 2007, only sporadic ZIKV cases were reported, with mild clinical manifestations in patients. Therefore, little attention was given to this virus before epidemics in the South Pacific and the Americas that began in 2013. Read More

Offspring Microbiomes Differ Across Breeding Sites in a Panmictic Species.

Front Microbiol 2019 6;10:35. Epub 2019 Feb 6.

Institute of Evolutionary Ecology and Conservation Genomics, University of Ulm, Ulm, Germany.

High dispersal rates are known to homogenize host's population genetic structure in panmictic species and to disrupt host local adaptation to the environment. Long-distance dispersal might also spread micro-organisms across large geographical areas. However, so far, to which extent selection mechanisms that shape host's population genetics are mirrored in the population structure of the enteric microbiome remains unclear. Read More

The respiratory syncytial virus vaccine landscape: lessons from the graveyard and promising candidates.

Lancet Infect Dis 2018 Oct 18;18(10):e295-e311. Epub 2018 Jun 18.

Laboratory of Translational Immunology, University Medical Centre Utrecht, Utrecht, Netherlands; Department of Paediatrics, Wilhelmina Children's Hospital, University Medical Centre Utrecht, Utrecht, Netherlands; Respiratory Syncytial Virus Network (ReSViNET) Foundation, Zeist, Netherlands. Electronic address:

The global burden of disease caused by respiratory syncytial virus (RSV) is increasingly recognised, not only in infants, but also in older adults (aged ≥65 years). Advances in knowledge of the structural biology of the RSV surface fusion glycoprotein have revolutionised RSV vaccine development by providing a new target for preventive interventions. The RSV vaccine landscape has rapidly expanded to include 19 vaccine candidates and monoclonal antibodies (mAbs) in clinical trials, reflecting the urgency of reducing this global health problem and hence the prioritisation of RSV vaccine development.

Clinical and echocardiographic factors associated with mitral plasticity in patients with chronic inferior myocardial infarction.

Eur Heart J Cardiovasc Imaging 2018 05;19(5):508-515

Department of Out patients Care, Echocardiography, Nuclear medicine National Instituto of Cardiology Ignacio Chávez, Juan Badiano No.1, Colonia Sección XVI, Tlalpan, Mexico City 14080, Mexico.

Aims: Ischaemic mitral regurgitation (IMR) is consequence of left ventricular (LV) remodelling after myocardial infarction. In some cases, the mitral valve enlarges to compensate for LV remodelling and tenting, improving its coaptation; a process termed 'plasticity'. We sought to identify clinical and echocardiographic factors associated with plasticity in patients with chronic inferior myocardial infarction (CII). Read More

Establishing Correlates of Protection for Vaccine Development: Considerations for the Respiratory Syncytial Virus Vaccine Field.

Viral Immunol 2018 03 16;31(2):195-203. Epub 2018 Jan 16.

6 Department of Molecular Virology and Microbiology, Baylor College of Medicine , Houston, Texas.

Correlates of protection (CoPs) can play a significant role in vaccine development by assisting the selection of vaccine candidates for clinical trials, supporting clinical trial design and implementation, and simplifying tests of vaccine modifications. Because of this important role in vaccine development, it is essential that CoPs be defined by well-designed immunogenicity and efficacy studies, with attention paid to benefits and limitations. The respiratory syncytial virus (RSV) field is unique in that a great deal of information about the humoral response is available from basic research and clinical studies. Read More
