GlossaryIntegrin

Integrins are transmembrane proteins that play a crucial role in cell adhesion, signaling, and communication within the extracellular matrix. In the context of hair biology, integrins are involved in the regulation of hair follicle development, cycling, and the interaction between hair follicle cells and their surrounding environment. Their relevance to hair loss lies in their influence on the health and function of hair follicles; disruptions in integrin signaling can contribute to conditions such as alopecia and other forms of hair thinning. Key distinguishing characteristics of integrins include their ability to bind to specific ligands and their role in mediating cellular responses to mechanical and biochemical signals.
