What forms part of the senescence associated secretory phenotype, or SASP?
The diverse arrays of proteins secreted by senescent cells have been described to influence aging and to have both pro-tumorigenic and anti-tumorigenic influences on the surrounding microenvironment. Further characterization of these proteins, known as the senescence-associated secretory phenotype (SASP), and their regulators is required to understand and further manipulate such activities. The senescence-associated secretory phenotype (SASP) is characterized by IL1B, CXCL8, CCL2, TNF, CCL27 and other pro-inflammatory factors including a novel SASP component CLEC11A.
