A self-powered chloroplast-driven nanophotosystem for treating skin photoaging through rejuvenating mitochondria and revitalizing senescent fibroblasts.
Article in Journal of nanobiotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Skin aging is an inevitable biological process caused by cellular senescence and overexposure to harmful environmental factors such as ultraviolet (UV) radiation. Senescent fibroblasts with proliferation arrest, mitochondrial dysfunction and nicotinamide adenine dinucleotide phosphate (NADPH) depletion have been proposed as a major mechanism driving skin photoaging, but the specific therapies are currently lacking. Inspired by the self-powering potential of plant-derived photosynthetic system, we herein fabricated a novel nanophotosynthetic platform that integrated Chlorella-derived nanothylakoid units (NTUs) with hyaluronic acid (HA)-based microneedles (MNs) to specifically target senescent fibroblasts for treating skin photoaging. By equipped with photosynthesis (PS)-I/II and quinolinate phosphoribosyltransferase (QPRT), the NTU-MN photosystem remarkably increased mitochondrial biogenesis and adenosine triphosphate (ATP) generation, resumed NAD(P)H pool and increased cellular anabolism, addressing the heighted bioenergetic and biosynthetic requirement for highly turnover of fibroblasts during photoaging. Furthermore, with skin penetrating ability of MNs and camouflaging of fibroblast membranes, topical application of the nanophotosystem facilitated the intradermal release of NTUs, leading to regeneration of damaged tissues, increased collagen synthesis, decreased senescence-associated secretory phenotype (SASP), and hence alleviated photoaging of skin. Thus, we developed a "green nanoplatform" with significantly anti-aging efficacy, biocompatibility, and biosafety, opening new avenues for light-driven therapies for degenerative diseases.
