Surface-bound matrix metalloproteinase-8 on macrophages: Contributions to macrophage pericellular proteolysis and migration through tissue barriers.
Article in Physiological reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveMMP-8 binds to surface-bound tissue inhibitor of metalloproteinase-1 (TIMP-1) on PMNs to promote pericellular proteolysis during the development of inflammatory diseases associated with tissue destruction. Little is known about the biology of MMP-8 in macrophages. We tested the hypotheses that: (1) MMP-8 and TIMP-1 are also expressed on the surface of activated macrophages, (2) surface-bound MMP-8 on macrophages promotes TIMP-resistant pericellular proteolysis and macrophage migration through tissue barriers, and (3) MMP-8 binds to surface-bound TIMP-1 on macrophages.
methodsSurface MMP-8 and TIMP-1 levels were measured on human monocyte-derived macrophages (MDM) and/or murine macrophages using immunostaining, biotin-labeling, and substrate cleavage methods. The susceptibility of membrane-bound Mmp-8 on activated macrophages from wild-type (WT) mice to TIMPs was measured. Migration of WT and Mmp-8
resultsLipopolysaccharides and a cluster of differentiation 40 ligand increased surface MMP-8 and/or TIMP-1 staining and surface type I collagenase activity on MDM and/or murine macrophages. Activated Mmp-8
conclusionsMMP-8 and TIMP-1 are expressed on the surface of activated human MDM and murine macrophages, but Mmp-8 is unlikely to bind to surface-bound Timp-1 on these cells. Surface-bound MMP-8 contributes to TIMP-resistant monocyte/macrophage pericellular proteolysis and macrophage migration through collagen-containing tissue barriers.
