FIG. 8.
Cytokine production by WNV-specific CD8+ T lymphocytes is not affected by depletion of SCS macrophages. CCL- or PBSL treated B6 mice (n=6) were inoculated in the FP with 107 IU RepliVAX WN. Lymphocytes from spleen and pLN were harvested on day 5 (n=2) or day 7 pi (n=4), stimulated and assayed for production of cytokines as described in methods. (A) Representative staining for IFN-γ and TNF-α in splenocytes stimulated with NS4B peptide, irrelevant peptide, or medium. The mean (± SD) frequency (B, D, F, H) or total cell number (C, E, G, I) of cytokine producing CD8+ T cells from the spleen or pLN are shown (*p <0.05).
