Rejuvenation Roundup April 2026

Aging is a multifaceted topic, and it’s becoming more and more clear that the only way to deal with it is piece by piece. Here’s what pieces our industry has put together in April.

Advocacy and Analysis

It’s Springtime and the Rejuvenation Field Is Flourishing: For those of us in the Northern Hemisphere, spring is here.

Life Bio’s Trial: Is the FDA Warming to Rejuvenation?: If this technique works in resetting the biological age of the human eye, the entire multibillion-dollar longevity industry could move to the center of mainstream medicine.

A Combination NAD+ Treatment Has Benefits for Mice: Researchers have found that simultaneously supplying NAD+ through NMN and reducing its loss through apigenin restores muscle function and bone structure to aged mice.

Affecting a Signaling Pathway Alleviates Alzheimer’s in Mice: The overexpression of somatostatin (SST), a neuropeptide produced in neurons and acting mostly on microglia, lowers inflammation and amyloid β burden, improving cognitive abilities in a mouse model of Alzheimer’s.

A Single Sauna Session Causes White Blood Cell Mobilization: A new study shows that hitting a sauna for 30 minutes causes a transient spike in the number of circulating white blood cells. The researchers suggest that this exercise-like effect might provide health benefits by improving immune surveillance.

Vitamin C Alleviates Aging in Cynomolgus Monkeys: A recent study described a process called ferro-aging, in which iron accumulation leads to oxidative damage and cellular senescence. This process can be delayed by Vitamin C.

Targeting an Appetite Hormone Receptor for Stronger Muscles: In Aging Cell, researchers have described how suppressing the ghrelin receptor improves muscle function and fights sarcopenia in older mice.

Engineered Stem Cells Become Lifelong Protein Factories: Researchers have genetically engineered blood stem cells to produce B cells that can churn out rare broad-action antibodies to fight HIV, malaria, and flu.

How Inflammaging Is Linked to Epigenetic Aging: A paper in Cell Genomics has described how age-related systemic inflammation is related to epigenetic aging as measured by four established clocks.

Rapamycin Might Blunt Exercise Response in Humans: According to a new study, rapamycin probably interferes with exercise, blunting its effects in older human subjects. This result, however, might be specific to the particular protocol.

The Immune System Ages Differently in Men and Women: An investigation into the aging immune system identified age-related changes, including sex-dependent differences, in immune cell subpopulations and gene expression.

Reprogrammed Cardiomyocytes Soften the Blow in Heart Attack: A new study has found that partial reprogramming mitigates the damage of myocardial infarction in mice by helping heart muscle cells to complete division.

A Robust Senescence Response Helps Wounds Heal: A team of scientists has examined how younger and older mice heal from wounds and found that more robust senescent cell activation in younger animals helps them heal faster.

Obesity’s Effects on the Immune System May Linger for Years: A new study has suggested that T cells might retain a pro-inflammatory phenotype long after normal weight is regained following a period of obesity.

A Popular Senolytic Treatment Causes Brain Damage in Mice: A new study calls for caution in using the well-known senolytic treatment of dasatinib and quercetin (D+Q), showing that it causes damage in certain regions of the brain, similar to what is observed in multiple sclerosis.

Daytime Napping and Mortality Association in Older Adults: A recent study found an association between longer and more frequent daytime napping and higher mortality risk.

Electromagnetic field-inducible in vivo gene switch for remote spatiotemporal control of gene expression: Overall, a remotely controlled EMF-inducible gene switch represents a versatile and effective biomedical platform.

Why dietary interventions fail or succeed in ageing: Metabolic resilience as the missing integrative framework: This perspective supports a shift towards resilience-oriented endpoints, improved biological stratification, and the integration of functional phenotypes into study design.

Epigenetic Age Feedback as a Catalyst for Sustained Lifestyle Change: One-Year Results from the EU iHelp Study: The marked variation between epigenetic clocks highlights the importance of selecting models designed for clear communication when used in public-facing health interventions.

The effects of metformin and exercise training on cardiorespiratory, blood pressure, and metabolic adaptations across the spectrum of glucose dysregulation: Compared with exercise alone, metformin was associated with smaller improvements in VO2peak, attenuated reductions in systolic blood pressure, and attenuated reductions in diastolic blood pressure.

Effects of high-load, velocity-intentional variable resistance training combined with creatine supplementation: Creatine supplementation confers complementary, modality-specific benefits and supports their use in combination to high-speed resistance exercise to promote healthy aging.

An Extracellular Matrix Aging Clock Based on Circulating Matrisome Proteins Predicts Biological Aging and Disease: These findings establish circulating ECM proteins as sensitive biomarkers of aging and disease and suggest that targeting ECM remodeling may offer new strategies for promoting healthy aging.

Harnessing viral strategies to reverse cognitive dysfunction through the integrated stress response: This treatment reversed cognitive and synaptic deficits in mouse models of Down syndrome, Alzheimer’s disease, and aging.

Combined effects of a low-dose multi-target supplement (CaHMB, CBP, and HA) on delaying musculoskeletal aging: The low-dose combination of CaHMB, CBP, and HA provides comprehensive benefits against age-related muscle and bone loss, likely by modulating the muscle–bone axis, and outperforms individual components.
