pubmed:abstractText |
We have compared chemokine secretion from human lung A549 cells infected with simian virus 5 (SV5) with other members of the Rubulavirus genus of paramyxoviruses. High levels of the chemokines interleukin-8 (IL-8) and macrophage chemoattractant protein-1 (MCP-1) were secreted from A549 cells infected with Human parainfluenza virus type 2 (HPIV-2) but not from cells infected with wild-type (WT) SV5. The lack of IL-8 secretion from SV5-infected cells was not due to a global block in all signal transduction pathways leading to IL-8 secretion, since SV5-infected A549 cells secreted IL-8 after stimulation with exogenously added tumor necrosis factor alpha or by coinfection with HPIV-2. A previously described, recombinant SV5 containing substitutions in the shared region of the P/V gene (rSV5-P/V-CPI-) induced IL-8 secretion by a mechanism that was dependent on viral gene expression. By contrast, an SV5 variant isolated from persistently infected cells (Wake Forest strain of Canine parainfluenza virus) induced IL-8 secretion by a mechanism that was largely not affected by inhibitors of viral gene expression. Together, these data demonstrate that SV5 is unusual compared to other closely related paramyxoviruses, since SV5 is a very poor inducer of the cytokines IL-8 and MCP-1. The isolation of two recombinant SV5 mutants that are defective in preventing chemokine induction will allow an identification of mechanisms utilized by WT SV5 to avoid activation of host cell innate immune responses to infection.
