Subcutaneous fat is more than a storage tank. In a Cell Metabolism mouse study, skin injury prompts macrophages to make fat cells release fatty acids; hair follicle stem cells take up these monounsaturated fatty acids via CD36, switch on Pgc1-alpha for energy, and exit dormancy to regrow hair, forming a macrophage-to-adipocyte-to-follicle metabolic relay.
IgA nephropathy is the most common primary glomerulonephritis worldwide. In a mouse study, antroquinonol, a purified compound from Antrodia camphorata mycelium, switched three pathways at once, activating Nrf2, restraining T cells, and silencing the NLRP3 inflammasome, easing kidney damage.

## You cut the seafood, so why is your uric acid still high? Most high uric acid is not something you ate: roughly **90%** of the problem is a kidney unable to
Resveratrol, rapamycin, and diet all claim to fight aging, so why do the effects vary so much? Studies in 2026 show anti-aging interventions succeed or fail depending on sex, life stage, and genetic background, pushing geroscience from a lifespan race toward hallmark-informed prioritization.
mTORC1 is the most famous molecular switch in aging research, yet how it gets turned on at the Golgi has stayed murky. A 2026 study shows the Golgi protein YIF1A recruits RNF126 to degrade G3BP1/2, releasing the brake on mTORC1; cells with YIF1A knocked down resist induced senescence, and worm experiments reveal the pathway tunes lifespan in both directions.
Four 2026 studies converge on one conclusion: brain aging is not the brain's problem alone. Peripheral CD8⁺ EMRA T-cell immunosenescence, plasma glucose with Mendelian Randomization causal evidence, and arterial wall cellular heterogeneity collapse are converging on the aging brain — while intracranial microglia and oligodendrocytes inflammage in near-perfect synchrony (Pearson r≈0.98). Understanding this multi-source siege reframes what prevention might realistically look like.
113 studies. Clear biological activity, inconclusive clinical benefit. A close read of the 2026 PRISMA review: what NR/NMN actually do, what they don't, and what often gets left out of the conversation.
