Cell type-specific autophagy in human leukocytes: signatures of aging, sex, and nutrient restriction.
Article in Autophagy reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Macroautophagy (referred to here as autophagy) is thought to play a critical role in aging and age-related disease, making it a priority for development of targeted human therapies. We developed a flow cytometry-based method to measure autophagic flux in 19 subpopulations from whole blood, using chloroquine (CQ) to inhibit lysosomal degradation, and the autophagy protein MAP1LC3B (microtubule associated protein 1 light chain 3 beta) isoform II/LC3B-II to measure autophagic flux (the acquisition and degradation of autophagic cargo over time). Autophagic flux varies by cell type and is higher in whole blood compared with RPMI culture media. Basal autophagic flux shows sex- and age-specific variations. Further, monocytes, but not T cells, respond robustly to amino acid starvation by increasing autophagy, with older individuals exhibiting stronger responses, particularly in non-classical monocytes. These findings underscore the importance of cell type-specific autophagy measurements to understand the effects of aging, sex and nutrition, to develop targeted interventions for age-related diseases.
