Medical Review Identifies Major Breakthroughs in Peptide Therapy Research: AI Tools, Anti-Aging Vaccines, and Oral Delivery Systems Lead 2025 Advances
The peptide therapy field experienced a transformative year in 2025, with breakthroughs spanning AI-assisted drug discovery, anti-aging immunotherapy, and oral delivery systems that could dramatically expand patient access to peptide treatments, according to a comprehensive research roundup published by AllAboutPeptides.com [https://allaboutpeptides.com/year-in-review-peptide-therapy-research-2025/].
The analysis, conducted under the medical oversight of Dr. Michael Fortunato, MD, a board-certified anesthesiologist specializing in hormone optimization, synthesizes peer-reviewed studies across mitochondrial therapeutics, metabolic health interventions, and longevity science published throughout 2025.
"What we're seeing is peptide therapeutics maturing from single-target interventions into sophisticated tools for addressing the complex biology of aging," said Dr. Fortunato. "The convergence of AI-powered discovery, novel delivery mechanisms, and immune-based approaches marks a turning point for the field."
Anti-Aging Vaccine Shows Multi-System Benefits
Among the year's most innovative developments, researchers at multiple institutions developed a peptide vaccine targeting CD38-an enzyme that depletes cellular NAD+ levels during aging. The vaccine improved glucose tolerance, reduced senescent cell burden, and enhanced NAD+ metabolism in aged mice, representing a shift from daily supplementation to long-lasting immune-mediated protection against age-related decline.
The study [https://onlinelibrary.wiley.com/doi/10.1111/acel.70026], published in Aging Cell, demonstrated that immunological approaches to slowing aging could provide sustained benefits without requiring continuous treatment-a potential game-changer for longevity interventions.
Artificial Intelligence Accelerates Peptide Discovery
Machine learning tools emerged as powerful accelerators for peptide research. The Anti-Aging Peptide Predictor (AAGP), developed by Datta and colleagues and published in Scientific Reports, integrates physicochemical and compositional features to identify anti-aging peptide candidates with high specificity, dramatically reducing discovery timelines and costs.
"AI-assisted peptide design could cut years off the development cycle," Dr. Fortunato noted. "What previously required extensive laboratory screening can now be predicted computationally, allowing researchers to focus resources on the most promising candidates."
Oral Delivery Systems Overcome Major Barrier
Advances in oral delivery formulations addressed peptide therapy's biggest practical challenge: bioavailability. New approaches to protecting peptides from gastrointestinal degradation could eliminate the need for injections, improving patient compliance and expanding access to peptide-based treatments for metabolic diseases.
Mitochondrial Peptides Target Cardiovascular Aging
Mitochondrial-derived peptides (MDPs) including humanin and MOTS-c demonstrated powerful effects on cardiovascular aging by modulating apoptosis, inflammation, and oxidative stress. Research published in Current Cardiology Reviews [https://www.eurekaselect.com/article/148940] revealed these peptides show dual potential as both therapeutics and biomarkers for cardiovascular disease.
Additional 2025 highlights include:
- FGF21 extending lifespan and improving insulin sensitivity in obese mice through pathways independent of traditional metabolic signaling
- Marine-derived collagen peptides from cod demonstrating lifespan extension and enhanced stress resistance in model organisms
- Elamipretide improving cardiac and skeletal muscle function in aged mice without altering traditional molecular aging markers
- Plant-derived bioactive peptides showing promise for metabolic dysfunction-associated fatty liver disease
"The breadth of sources-from marine organisms to velvet antler to AI-designed sequences-demonstrates how diverse approaches are converging on common aging mechanisms," said Dr. Fortunato. "As our understanding grows more nuanced and delivery technologies improve, peptide therapies are positioned to play a central role in extending human healthspan."

Peptide Modifications For PEGylation
PEGylation is the process of covalently attaching polyethylene glycol (PEG) polymer chains to peptides. By increasing their molecular mass and shielding them from proteolytic enzymes, PEGylation improves the pharmacokinetics of peptides and proteins. PEGylation reduces renal clearance and results in more sustained absorption after subcutaneous administration, as well as restricted distribution. PEGylations have been shown to significantly improve water solubility, biocompatibility, immunogenicity, and other physico-chemical properties. It is an established…
