Abstract

The aging of the immune system drives systemic aging and the pathogenesis of age‐related diseases. However, a significant knowledge gap remains in understanding immune‐driven aging, especially in brain aging, due to the limited current in vitro models of neuroimmune interaction. Here, the authors report the development of a human brain organoid microphysiological analysis platform (MAP) to discover the dynamic process of immune‐driven brain aging. The organoid MAP is created by 3D printing that confines organoid growth and facilitates cell and nutrition perfusion, promoting organoid maturation and their committment to forebrain identity. Dynamic rocking flow is incorporated into the platform that allows to perfuse primary monocytes from young (20 to 30‐year‐old) and aged (>60‐year‐old) donors and culture human cortical organoids to model neuroimmune interaction. The authors find that the aged monocytes increase infiltration and promote the expression of aging‐related markers (e.g., higher expression of p16) within the human cortical organoids, indicating that aged monocytes may drive brain aging. The authors believe that the organoid MAP may provide promising solutions for basic research and translational applications in aging, neural immunological diseases, autoimmune disorders, and cancer.

  • Monocytes derived from patients with AD and age-matched controls may exhibit age-relevant phenotypes, given that aging is the primary risk factor for AD.

    “The use of primary human monocytes also has several advantages: (i) their human origin enables the study of human-specific disease phenotypes and molecular mechanisms, (ii) monocytes derived from patients with AD may contain cell-intrinsic properties specific to that patient, and (iii) monocytes derived from patients with AD and age-matched controls may exhibit age-relevant phenotypes, given that”

    The Results (Investigation of Monocyte-Driven Brain Aging; page unavailable) report aging-related changes when monocytes from older donors were cultured with brain organoids, supporting the possibility of age-relevant phenotypes. The Experimental Section (Isolation of Monocytes from Human PBMCs; page unavailable) specifies that donors were healthy young and elderly people, not patients with AD and age-matched controls. The cited passages also do not establish that aging is the primary risk factor for AD. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
