The IGF System and Aging - Takeaways - MDSpire

The Role of the IGF System in the Aging Process

Share

1

IGF signaling plays a crucial role in the aging process, influencing cellular senescence and age-related diseases.
2

The IGF system comprises various receptors, ligands, binding proteins, and inhibitors that regulate IGF activity in a complex manner.
3

IGF-IR mediates cell survival and differentiation, while IGF-IIR primarily functions to attenuate IGF signaling.
4

High-affinity IGF binding proteins modulate IGF action and can have context-dependent effects on cellular processes.
5

Proteolytic cleavage of IGFBPs by specific proteinases regulates IGF signaling, highlighting the intricate control of the IGF system.
