CCL23 also known as macrophage inflammatory protein 3 is a chemokine involved in immune response regulation. It has a molecular weight of approximately 15-16 kDa and is secreted by various cells such as macrophages dendritic cells and endothelial cells. CCL23 is expressed mostly in the bone marrow and lymph nodes but it also localizes in tissues like the liver and lungs under certain conditions. It plays an important role in mediating chemotaxis directing the migration of cells toward infection sites.

Biological function summary

CCL23 functions in the recruitment of immune cells especially eosinophils and monocytes to areas where immune responses are necessary. This chemokine is not known to be part of a larger protein complex but its ability to interact with specific receptors on cell surfaces makes it integral to immune signaling. During immune activation CCL23 contributes to the inflammatory cascade influencing both acute and chronic inflammatory responses.

Pathways

The signaling functions of CCL23 integrate within the chemokine signaling pathway and the broader immune response pathway. CCL23 interacts closely with proteins such as CCR1 which acts as its receptor and influences cellular responses via this receptor-mediated signaling. Additionally CCL23 shares mechanistic parallels with other chemokines like CCL22 though they may attract different subsets of cells they participate in coordinated immune activities.

CCL23 has relevance to conditions such as rheumatoid arthritis and allergic reactions. In these diseases elevated levels of CCL23 and its interaction with other proteins such as CCR1 contribute to the recruitment and activation of inflammatory cells. This chemokine's role in immune cell trafficking and inflammation makes it a target for therapeutic interventions aimed at modulating immune responses in such disorders.
