Immuno-potentiating pathway of HBsAg-HBIG immunogenic complex visualized.
Article in Human vaccines & immunotherapeutics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Chronic viral hepatitis B (CHB) is a major global health problem. A therapeutic vaccine for CHB comprised of yeast-derived recombinant HBsAg-anti-HBs immunogenic complexes (YIC) has been devloped by us. A series of clinical trials has shown its therapeutic efficacy in decreasing HBV viral load and converting serum HBeAg-positive to anti-HBe-positive status in a subpopulation of CHB patients. Herein, we present a study of the immuno-potentiating mechanisms of YIC revealed by live-cell imaging technology. We studied internalization and dissociation of YIC in cells in vitro, and antigen presentation and T cell stimulation in mice. We found that after YIC was internalized via the Fcγ receptors (FcγR) of antigen presenting cells, it was subsequently transferred through early and late endosomal into lysosomal compartments. The dissociation of YIC was mainly observed in the late endosome. Furthermore when YIC were injected into mice, the populations of IFN-γ- and TNF-α-producing CD8+ and CD4+ T cells were higher in the YIC group than in controls receiving antigen or antibody alone. These observations supplement the known mechanisms of YIC action as a therapeutic vaccine for CHB.
