Abstract | The purpose of this study was to look for associations between a newly described class of suppressors of cytokine signaling (SSI/SOCS) andcytokine expression in the uterine cervix from HIV/HPV coinfected women. We examined the pro-inflammatory cytokines TNF-α and IL-6 since their expressions are linked and responsible for many aspects of both localized and systemic inflammatory responses. Further, expression of SSI/SOCS has been implicated in the negative feedback regulation of cytokine receptor signaling. PCR-amplified HIV-1 cDNA was noted mainly in the stroma, showing a perivascular distribution, and most of the infected cells colabeled with the macrophage marker CD68. The distribution of IL-6 and TNF-α was in the same area to HIV-1 and much greater than normal cervices from women with no evidence of viral infection. SOCS/SSI-1 and -3 mRNA positive cells in the uterine cervix were commonly detected in these noninfected cervical tissues; however, very few cells that contained SOCS were evident in areas where HIV-1, TNF-α, and IL-6 expressing cells were found. This suggests that viral-related suppression of SOCS/SSI-1-3 expression may be a factor in the marked local enhancement of TNF-α and IL-6 production which, in turn, may help facilitate viral spread; however, further studies should be done in order to elucidate the exact mechanisms of SOCS in the cervix. | |
