Senomorphic Agents: Multi-Target Strategies To Tame The Senescence-Associated Secretory Phenotype For Healthy Ageing
As we age, some of our cells enter a state called “senescence,” where they stop dividing but remain active. While these senescent cells can be beneficial in certain situations, their accumulation over time contributes to aging and age-related diseases. A key problem with these cells is something called the “senescence-associated secretory phenotype,” or SASP. Think of SASP as a cocktail of inflammatory molecules, growth factors, and enzymes that senescent cells release into their surroundings. This cocktail can cause chronic inflammation, damage nearby healthy tissues, and accelerate the aging process throughout the body.
Scientists are exploring different strategies to combat the negative effects of senescent cells. One approach involves “senolytics,” which are drugs that selectively kill these senescent cells. Another promising strategy focuses on “senomorphics.” Instead of eliminating senescent cells, senomorphics aim to neutralize their harmful SASP. These agents work by targeting various pathways within the senescent cells to reduce or alter the problematic substances they secrete. By taming the SASP, senomorphics can help reduce inflammation, protect tissues from damage, and potentially delay the onset of age-related diseases, contributing to a healthier lifespan without necessarily removing the senescent cells themselves.
