Nabosignalering

Nabosignalering, often translated as neighbor signaling, is a phenomenon observed in biological systems where cells communicate with their immediate surroundings to coordinate activities. This communication typically involves the release of signaling molecules by a cell, which then diffuse a short distance to bind with receptors on neighboring cells. These receptors then trigger a response within the receiving cell, influencing its behavior, gene expression, or differentiation.

The concept is fundamental to understanding tissue development, immune responses, and wound healing. For instance, during embryonic development, nabosignalering helps cells organize into distinct tissues and organs by guiding their migration and specialization. In the immune system, it allows immune cells to coordinate their attack against pathogens or to initiate inflammatory responses at the site of infection.

The signaling molecules involved in nabosignalering can vary widely, including small peptides, lipids, and even ions. The short-range nature of this communication ensures that responses are localized and specific to the immediate cellular environment. This contrasts with endocrine signaling, where hormones travel through the bloodstream to affect distant target cells. Nabosignalering is a critical mechanism for maintaining tissue homeostasis and orchestrating complex multicellular processes.
