Targeting Cellular Senescence

A physician-guided approach to one of the biological hallmarks of aging.

As we age, damaged and dysfunctional cells can accumulate rather than being cleared normally. These senescent cells may release inflammatory and signaling molecules that affect surrounding tissues, a phenomenon increasingly studied in aging, metabolic disease, musculoskeletal health, and other age-related conditions.

At the Institute for Human Optimization, senotherapeutic strategies are considered selectively within a broader longevity medicine program, not as a universal anti-aging treatment.

What Are Senescent Cells?

When Cells Stop Dividing, but Don’t Disappear

Senescence is a state in which a cell stops dividing in response to stress or damage but remains active, sending signals to the tissue around it.

  1. Step 01

    Healthy cell

    Divides and functions normally within its tissue.

  2. Step 02

    Stress or damage

    DNA damage, oxidative stress, or other cellular insults.

  3. Step 03

    Senescent cell

    Stops dividing but is not cleared normally, so it can accumulate.

  4. Step 04

    SASP

    Releases inflammatory and signaling molecules.

  5. Step 05

    Tissue effects

    A persistent signaling environment that may affect surrounding tissue.

An important nuance

Cellular senescence is not inherently harmful. It plays important roles in processes including wound healing and tumor suppression. The concern is the age-related accumulation of senescent cells and their persistent signaling environment.

Useful roles

Wound healing and tumor suppression.

The concern

Accumulation with age and a persistent inflammatory signaling environment.

Senolytics vs. Senomorphics

Two Different Strategies

Senolytics

Target Senescent Cells

Senolytic compounds are being investigated for their ability to selectively promote the clearance of certain senescent cells.

Because senescent cells take time to accumulate again, investigational approaches generally use intermittent exposure rather than continuous treatment.

ClearanceIntermittent exposure
Senomorphics

Modify Senescent-Cell Signaling

Senomorphic strategies take a different approach. Rather than eliminating senescent cells, they attempt to modify pathways involved in the inflammatory secretions associated with cellular senescence, including the senescence-associated secretory phenotype (SASP).

SignalingSASP modulation

Both strategies remain areas of active research. Neither is a proven treatment for aging.

Why Cellular Senescence Matters

One of the Hallmarks of Aging

Cellular senescence is recognized as one of the biological hallmarks of aging. Researchers are studying how senescent-cell biology relates to several areas of health.

  • Research area

    Metabolic Health

    Insulin sensitivity and fat-tissue biology.

  • Research area

    Musculoskeletal Aging

    Bone, joint, and muscle tissue.

  • Research area

    Immune Aging

    Immune function and chronic, low-grade inflammation.

  • Research area

    Vascular Biology

    Blood vessel function and vascular aging.

  • Research area

    Frailty & Physical Function

    Strength, mobility, and resilience with age.

  • Research area

    Neurodegenerative Biology

    Research into brain aging.

These associations do not mean that senolytic therapy has been proven to prevent or treat these conditions.

Not Everyone Needs Senolytics

We Don’t Treat Aging With a Prescription Pad.

Senescent cells serve biological functions, and current research does not support indiscriminate senolytic treatment for every healthy adult.

At the Institute, the question isn’t simply
“How old are you?”
It’s
“Is there evidence that targeting cellular senescence makes biological and clinical sense for you?”

What we consider

The focus is on patients whose evaluation suggests a higher senescent-cell burden, rather than treating everyone.

  • Inflammatory markers
  • Metabolic health
  • Physical function
  • Body composition
  • Bone health
  • Medical history
  • Medication interactions
  • Research-oriented aging & senescence markers
Our Senotherapeutic Process

Four Stages, One Question at a Time

Each stage has to justify the next. Many patients complete the evaluation and never proceed to treatment, and that is a valid outcome.

Stage 01

Biological Evaluation

We begin by understanding your biology, health history, and goals before any intervention is considered.

  • Medical history
  • Medication review
  • Metabolic health
  • Inflammatory biomarkers
  • Body composition
  • Physical function
  • Relevant aging biomarkers

Evaluation may include laboratory testing such as a CBC and CMP, metabolic and inflammatory markers, functional measurements, DEXA, and, where appropriate, research-grade aging or senescence markers.

Stage 02

Determine Biological Suitability

Not every patient proceeds.

The physician evaluates potential benefit, contraindications, medication interactions, and whether there is sufficient rationale for intervention.

  • Potential benefit
  • Contraindications
  • Medication interactions
  • Sufficient rationale
Stage 03

Personalized Senotherapeutic Strategy

Depending on your biology and medical history, the physician may consider different investigational approaches.

Senolytic · investigational

Dasatinib + Quercetin

An investigational senolytic combination with some of the most developed human translational evidence for senescent-cell targeting.

Senolytic · investigational

Fisetin

A naturally occurring flavonoid under investigation as a senolytic, with an emerging but currently limited human evidence base.

mTOR modulation · research

Rapamycin / Sirolimus

An mTOR-modulating medication being studied in aging biology that may influence pathways associated with cellular senescence and the SASP.

None of these agents is FDA approved to treat aging. Agent selection, dosing, and scheduling are individualized by your physician.

Stage 04

Measure. Reassess. Decide.

If we intervene in biology, we measure biology.

Treatment isn’t simply prescribed and forgotten. Patients undergo appropriate safety monitoring after any new agent is introduced, followed by longitudinal reassessment against their own baseline. Together, you and your physician decide whether to continue, adjust, or stop.

  • hs-CRP
  • IL-6
  • Fasting insulin
  • HbA1c
  • Lipids
  • Body composition
  • DEXA
  • Grip strength
  • Gait speed
  • Functional capacity
  • Biological-age measures

Outcomes are interpreted longitudinally and in clinical context, not as isolated numbers.

The Evidence

From Cellular Biology
to Human Translation

Senotherapeutics represent an emerging area of geroscience focused on the biology of cellular senescence. Early human studies have demonstrated measurable biological activity, while ongoing clinical research continues to evaluate how these changes may translate into improvements in health, function, and healthy aging.

An evolving field moving from biological discovery toward clinical translation.

Biological Activity 01

Senescent Cell Targeting

Human studies of certain investigational senolytic approaches have demonstrated measurable changes in markers associated with cellular senescence and the senescence-associated secretory phenotype.

Human Translation 02

Functional & Clinical Outcomes

Early clinical studies have reported signals across select functional and biological outcomes. Results vary by population and endpoint, reinforcing the importance of thoughtful patient selection and continued research.

Active Research 03

Healthspan & Longevity

Whether targeting cellular senescence can meaningfully influence long-term healthspan or lifespan in humans remains an important area of investigation. Long-term clinical outcomes have not yet been established.

The IFHO Approach

Follow the evidence as it evolves, select patients thoughtfully, measure outcomes, and adjust accordingly.

Senotherapeutic strategies remain investigational for longevity and healthy aging. Evidence summaries reflect the current state of research and are reviewed as new clinical data emerge.
