Journal ArticleDOI
Poxviruses and Immune Evasion
Bruce T. Seet,James B. Johnston,Craig R. Brunetti,John W. Barrett,Helen Everett,Cheryl M. Cameron,Joanna Sypula,Steven H. Nazarian,Alexandra Lucas,Grant McFadden +9 more
TL;DR: Because of their anti-inflammatory nature, many of these poxvirus proteins hold promise as potential therapeutic agents for acute or chronic inflammatory conditions.
Journal ArticleDOI
The T1/35kDa family of poxvirus-secreted proteins bind chemokines and modulate leukocyte influx into virus-infected tissues.
Kathryn Graham,Alshad S. Lalani,Joanne Macen,Traci L. Ness,Michele Barry,Li Ying Liu,Alexandra Lucas,Ian Clark-Lewis,Richard W. Moyer,Grant McFadden +9 more
TL;DR: In rabbits infected with a mutant rabbitpox virus, there was an increased number of extravasating leukocytes in the deep dermis during the early phases of infection, suggesting that members of the T1/35kDa class of secreted viral proteins bind multiple members ofThe chemokine superfamily in vitro and modulate the influx of inflammatory cells into virus-infected tissues in vivo.
Journal ArticleDOI
Myxoma virus M-T7, a secreted homolog of the interferon-gamma receptor, is a critical virulence factor for the development of myxomatosis in European rabbits.
Karen L. Mossman,Patrick N. Nation,Joanne Macen,Michael Garbutt,Alexandra Lucas,Grant McFadden +5 more
TL;DR: It is concluded that M-T7 functions early in infection to retard inflammatory cell migration into infected tissues and disrupt the communication between sentinel immune cells at the site of primary virus infection in the subdermis and lymphocytes in the secondary lymphoid organs, thereby disabling the host from mounting an effective cellular immune response.
Journal ArticleDOI
Virus-Encoded Serine Proteinase Inhibitor SERP-1 Inhibits Atherosclerotic Plaque Development After Balloon Angioplasty
Alexandra Lucas,Li Ying Liu,Joanne Macen,Piers Nash,Erbin Dai,Michael W. Stewart,Kathryn Graham,Wai S. Etches,Lynn K. Boshkov,Patric N. Nation,Dennis Humen,Marita Hobman,Grant McFadden +12 more
TL;DR: Purified SERP-1, a virus-encoded secreted glycoprotein, reduces plaque growth after primary balloon-mediated injury and is associated with a focal reduction in macrophage infiltration immediately after injury.
Journal ArticleDOI
Secreted Immunomodulatory Viral Proteins as Novel Biotherapeutics
TL;DR: Viral immunomodulatory proteins that have been tested as anti-inflammatory reagents in animal models of disease caused by excessive inflammation or hyperactivated immune pathways are reviewed.
