Tetrandrine regulates NAADP-mediated calcium signaling through a LIMP-2-dependent and sphingosine-mediated mechanism.
Article in Nature communications, 2025. 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
Tetrandrine (Tet) is a potent inhibitor of Ebola virus replication by blocking NAADP-dependent calcium release through endolysosomal two-pore channels (TPCs) and a moderately potent anti-tumor agent. Using a clickable photoaffinity probe, we identify lysosomal integral membrane protein-2 (LIMP-2) as a direct target of Tet and a key regulator of this calcium signaling. Tet binds LIMP-2's ectodomain, inhibiting lysosomal cholesterol and sphingosine transport, which alters lipid metabolism. Tet treatment and LIMP-2 depletion inhibit NAADP-dependent calcium release, reversible by removing lysosomal cholesterol and sphingosine. Sphingosine triggers lysosomal calcium release via TPCs and restores this signaling in Tet-treated or LIMP-2-deficient cells, revealing a LIMP-2-regulated, sphingosine-dependent lysosomal calcium pathway. At higher doses, Tet induces apoptosis through unfolded protein response activation independently of LIMP-2. These findings highlight Tet as a LIMP-2 inhibitor, elucidate its role in calcium signaling and cell death, and suggest therapeutic potential for Tet and LIMP-2 inhibitors in antiviral treatments.
