The proinflammatory cytokine IL-1 was marginally secreted by mock-infected and TB40/E-infected monocytes incubated with NDV and IFN- however was hugely upregulated by uninfected cells in response to LPS (Fig. 5), whilst this was not correct for virus-infected cells. The cytokines CXCL10 and CCL8 had been made to considerable levels by mock-infected monocytes in response to NDV, IFN- , and LPS, yet TB40/E-infected cells failed to make each CXCL10 and CCL8 following secondary challenge (Fig. five). While the chemokine CX3CL1 was secreted at low levels by both mockinfected and TB40/E-infected monocytes, only secondary challenge with LPS brought on elevated production of CX3CL1 in virusinfected cells (Fig. 5), whereas mock-infected cells secreted CX3CL1 in response to all treatment options.

The results demonstrate that latently infected monocytes respond selectively to triggers of innate immunity. This implies that latent HCMV alters the cellular function in the monocyte to benefit carriage from the virus and inhibit premature reactivation with the virus and/or immune detection. Most importantly, TB40/E-infected monocytes failed to upregulate IFN(see Table S3 inside the supplemental material) in response to second-250 200 150 one hundred 50 0 600 450 300 150 0CX3CLMock NDV IFN LPS IL60 CXCL10 45 30 15 0 (10-2) Mock NDV IFN LPS 120 IL10 90 60 30 0 (10-1) Mock NDV IFN LPS 80 CCL8 60 40 20 0 (10-2) Mock NDV IFN LPS TB40/EMock NDV IFN LPS CCLpg/ml100 60 0 (10-2) Mock NDV IFN LPS MockFIG 5 Latent HCMV alters monocyte responses to activators of innate immunity.
