    GlossaryGap Junctions

    Gap junctions are specialized intercellular connections that allow for direct communication between adjacent cells through the exchange of ions and small molecules. In the context of hair biology, they play a crucial role in maintaining the homeostasis of hair follicle cells and facilitating the signaling necessary for hair growth and cycling. Key distinguishing characteristics of gap junctions include their formation by connexin proteins, which assemble to create channels that bridge the cytoplasmic space between cells, enabling coordinated cellular responses that are vital for healthy hair follicle function. Disruption of gap junction communication can contribute to hair loss and other hair disorders.
