Rapid clearance of syngeneic transplanted hepatocytes following transduction with E-1-deleted adenovirus indicates early host immune responses and offers novel ways for studying viral vector, target cell and host interactions.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To distinguish between transduced cell clearance and transgene regulation following adenoviral gene transfer, we infected F344 rat hepatocytes with an E-1-deleted adenovirus (Ad beta gal) and studied cell survival in the liver of dipeptidyl peptidase IV-deficient (DPPIV-) F344 rats. Transplanted cells were localized with histochemical staining for DPPIV and transgene expression localized with staining for beta-galactosidase (lacZ). The transgene was expressed in 90-100% hepatocytes without impairment in cell viability in vitro, although transplanted cells were cleared mostly within 1 day by infiltrates containing activated macrophages, CD4+ or CD8+ lymphocytes, and phagocytes. When Ad beta gal-transduced hepatocytes were transplanted repeatedly at 14-day intervals, transplanted cells were cleared rapidly each time. LacZ expression following Ad beta gal administration to intact animals was associated with apoptosis and unscheduled DNA synthesis in the liver. To determine whether adenoviral antigen expression activated consequential MHC-restricted liver injury, we transplanted Ad beta gal-hepatocytes followed subsequently by transplantation of nontransduced hepatocytes. Transplanted cells expressing Ad beta gal were rapidly cleared as before, whereas nontransduced hepatocytes engrafted with progressive liver repopulation. The findings indicated that adenovirally transduced cells are cleared early in the host liver. Use of ex vivo strategies will facilitate analysis of modified adenoviral vectors in the context of immunoregulatory, cellular and viral mechanisms.
