Rapid generation of multivirus-specific T lymphocytes for the prevention and treatment of respiratory viral infections.

Haematologica 2019 Apr 19. Epub 2019 Apr 19.

Center for Cell and Gene Therapy, Baylor College of Medicine, Houston, TX, USA

Respiratory tract infections due to community-acquired respiratory viruses including respiratory syncytial virus, Influenza, parainfluenza virus 3 and human metapneumovirus are detected in up to 40% of allogeneic hematopoietic stem cell transplant recipients in whom they cause severe symptoms including pneumonia and bronchiolitis and can be fatal. Given the lack of effective antivirals and the data from our group demonstrating that adoptively transferred ex vivo-expanded virus-specific T cells can be clinically beneficial for the treatment of both latent (Epstein-Barr virus, cytomegalovirus, BK virus, human herpesvirus 6) and lytic (adenovirus) viruses, we investigated the potential for extending this immunotherapeutic approach to respiratory viruses. We now describe a system that rapidly generates a single preparation of polyclonal (CD4+ and CD8+) virus-specific T cells reactive against 12 antigens derived from 4 viruses (respiratory syncytial virus, Influenza, parainfluenza virus 3 and human metapneumovirus) that commonly cause post-transplant morbidity and mortality.

[Update on the management of bronchiolitis].

Rev Med Liege 2019 Apr;74(4):175-178

Service de Pédiatrie, CHU Liège, Belgique.

Bronchiolitis is one of the main reasons for hospitalization, or outpatient visits, in the paediatric population, especially among infants in the winter season. Despite the high incidence of the disease, ideal medical work up and treatment are still a matter of debate in the literature and among physicians. However, the most recent guidelines and review of literature do agree on some points. Read More

An obligatory role for club cells in preventing obliterative bronchiolitis in lung transplants.

JCI Insight 2019 Apr 16;5. Epub 2019 Apr 16.

Obliterative bronchiolitis (OB) is a poorly understood airway disease characterized by the generation of fibrotic bronchiolar occlusions. In the lung transplant setting, OB is a pathological manifestation of bronchiolitis obliterans syndrome (BOS), which is a major impediment to long-term recipient survival. Club cells play a key role in bronchiolar epithelial repair, but whether they promote lung transplant tolerance through preventing OB remains unclear. Read More

Contribution of Fcγ Receptor-Mediated Immunity to the Pathogenesis Caused by the Human Respiratory Syncytial Virus.

Front Cell Infect Microbiol 2019 29;9:75. Epub 2019 Mar 29.

Millennium Institute on Immunology and Immunotherapy, Departamento de Genética Molecular y Microbiología, Facultad de Ciencias Biológicas, Pontificia Universidad Católica de Chile, Santiago, Chile.

The human Respiratory Syncytial Virus (hRSV) is the leading cause of severe acute lower respiratory tract infections (ALRTIs) in humans at all ages and is the main cause of hospitalization due to pneumonia, asthma, and bronchiolitis in infants. hRSV symptoms mainly develop due to an excessive host immune and inflammatory response in the respiratory tissue. hRSV infection during life is frequent and likely because of non-optimal immunological memory is developed against this virus.

Perspectives in veterinary medicine: Description and classification of bronchiolar disorders in cats.

J Vet Intern Med 2019 Apr 13. Epub 2019 Apr 13.

Department of Pathobiology and Diagnostic Investigation, College of Veterinary Medicine, Michigan State University, East Lansing, Michigan.

This Perspectives in Veterinary Medicine article seeks to define, describe putative causes, and discuss key diagnostic tests for primary and secondary bronchiolar disorders to propose a classification scheme in cats with support from a literature review and case examples. The small airways (bronchioles with inner diameters <2 mm), located at the transitional zone between larger conducting airways and the pulmonary acinus, have been overlooked as major contributors to clinical syndromes of respiratory disease in cats. Because the trigger for many bronchiolar disorders is environmental and humans live in a shared environment with similar susceptibility, understanding these diseases in pet cats has relevance to One Health.

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

Therapeutic Targeting Steroid Resistant Pro-Inflammatory NK and NKT-Like Cells in Chronic Inflammatory Lung Disease.

Int J Mol Sci 2019 Mar 26;20(6). Epub 2019 Mar 26.

Lung Research Unit, Department of Thoracic Medicine, Royal Adelaide Hospital, Adelaide 5001, Australia.

The innate immune system drives the initiation of inflammation and progression to chronic inflammation in two important chronic inflammatory lung diseases involving the small airways, chronic obstructive pulmonary disease (COPD) and bronchiolitis obliterans syndrome (BOS), following lung transplantation. Recently natural killer T cell like (NKT-like) cells, which represent a bridge between the innate and adaptive immune response as well as the innate natural killer cell (NK) cells, have been shown to be important cells in these two chronic lung diseases. Importantly these cells have been shown to be resistant to commonly used anti-inflammatory drugs such as glucocorticoids and as such their inflammatory nature has been difficult to suppress.

Prophylactic digoxin treatment reduces IL-17 production in vivo in the neonatal calf and moderates RSV-associated disease.

PLoS One 2019 25;14(3):e0214407. Epub 2019 Mar 25.

Department of Diagnostic Medicine and Pathobiology, Kansas State University, Manhattan, Kansas, United States of America.

Respiratory syncytial virus (RSV) is a leading cause of morbidity and mortality in human infants. Bovine RSV infection of neonatal calves is pathologically and immunologically similar to RSV infection in infants, and is therefore a useful preclinical model for testing novel therapeutics. Treatment of severe RSV bronchiolitis relies on supportive care and may include use of bronchodilators and inhaled or systemic corticosteroids. Read More
