Abstract:
PURPOSE:To investigate cytokine mRNA expression during the inflammatory process induced in the contralateral eyes by uniocular inoculation of herpes simplex virus type 1 (HSV-1) via the anterior chamber. METHODS:BALB/c mice were inoculated in the anterior chamber with 5 x 10(4) plaque-forming units of HSV-1 (KOS). mRNA was extracted from the inflamed posterior segments of the uninoculated eyes at 0 (control), 9, 11, 14, and 21 days postinoculation (p.i.). Reverse transcription-polymerase chain reaction was performed for semiquantitative analysis of mRNA expression of interleukin (IL)-1beta, IL-2, IL-4, IL-10, IL-12p35, IL-12p40, interferon (IFN)gamma, tumor necrosis factor (TNF)alpha, transforming growth factor (TGF)beta2 and induced nitric oxide synthase (iNOS). RESULTS:Peak mRNA expression of iNOS was observed at day 14 p.i. The time profiles of mRNA expression for IL-1beta, IL-2, IL-4, IL-10, IFN-gamma, TNFalpha were similar to that of iNOS, while TGFbeta2, IL-12p35, and IL-12p40 demonstrated a reverse pattern. CONCLUSIONS:The kinetics of the analyzed cytokines synchronized with the clinicopathological activity of the experimental murine HSV-1 retinitis. The immunosuppressive cytokines TGFbeta2 and IL-10 demonstrated different peaks of mRNA expressions suggesting that the down-regulation phase of the inflammatory process was controlled by several factors working at different phases.
