Cannabinoid Receptor Type 2 Agonist JWH-133 Stimulates Antiviral Factors and Decreases Proviral, Inflammatory, and Neurotoxic Proteins in HIV-Infected Macrophage Secretome.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Although antiviral therapy has improved quality of life, around 50% of people with HIV (PWH) experience neurodegeneration and cognitive decline. This is prompted in part by the migration of HIV-infected monocyte-derived macrophages (MDMs) to the brain, leading to neuronal death. Previous studies in our lab have shown that HIV-infected MDMs secrete cathepsin B (CATB), which is a pro-inflammatory neurotoxic enzyme that is reduced by the addition of cannabinoid receptor-2 (CB2R) agonist JWH-133 to cell cultures. In this study, we aimed to identify the proteins secreted (secretome) by HIV-infected macrophages exposed to JWH-133 and quantify them using tandem mass tag (TMT) mass spectrometry. Frozen 13-day MDM supernatants from (1) an MDM negative control; (2) HIV+MDM, and (3) HIV+MDM-JWH-133 were compared in triplicate by mass spectrometry (LC/MS/MS) and analyzed for protein identification. Subsequently, the same samples were labeled by TMT labeling and quantified by LC/MS/MS. After a database search, 528 proteins were identified from all groups. Thereafter, proteins with more than three unique peptides and more than 10% coverage were selected for protein identification. Venn diagrams revealed one unique protein secreted by MDM-HIV, 10 unique proteins in HIV+MDM-JWH-133, and 15 common proteins in the three groups. CATB was unique to HIV+MDM. HIV+MDM exposed to JWH-133 showed proteins related to metabolism, cell organization, antiviral activity, and stress response. TMT analysis revealed 1454 proteins with abundance for statistical analysis based on FC ≥ |1.5| and
