CNS-wide Sexually Dimorphic Induction of the Major Histocompatibility Complex 1 Pathway With Aging.

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
The major histocompatibility complex I (MHCI) pathway, which canonically functions in innate immune viral antigen presentation and detection, is functionally pleiotropic in the central nervous system (CNS). Alternative roles include developmental synapse pruning, regulation of synaptic plasticity, and inhibition of neuronal insulin signaling; all processes altered during brain aging. Upregulation of MHCI components with aging has been reported; however, no systematic examination of MHCI cellular localization, expression, and regulation across CNS regions, life span, and sexes has been reported. In the mouse, MHCI is expressed by neurons and microglia, and MHCI components and receptors (H2-K1, H2-D1, β2M, Lilrb3, Klra2, CD247) display markedly different expression profiles across the hippocampus, cortex, cerebellum, brainstem, and retina. MHCI components, receptors, associated inflammatory transcripts (IL1α, IL1β, IL6, TNFα), and TAP (transporter associated with antigen processing) components are induced with aging and to a greater degree in female than male mice across CNS regions. H2-K1 and H2-D1 expression is associated with differential CG and non-CG promoter methylation across CNS regions, ages, and between sexes, and concomitant increased expression of proinflammatory genes. Meta-analysis of human brain aging data also demonstrates age-related increases in MHCI. Induction of MHCI signaling could contribute to altered synapse regulation and impaired synaptic plasticity with aging.
