Kemokin

Kemokin is a classification of small signaling proteins known as chemokines, which play a crucial role in the immune system by directing the migration of immune cells to sites of inflammation, infection, or injury. These molecules belong to the larger family of cytokines and are characterized by their ability to induce directed chemotaxis in nearby responsive cells.

Chemokines are categorized into four main subfamilies based on the arrangement of conserved cysteine residues: CXC, CC, CX3C, and XC. Kemokin, specifically, is often used as a term in certain languages and regions to refer to chemokines, though in broader scientific contexts, the term "chemokine" is more universally applied.

Functionally, kemokins bind to specific G-protein-coupled receptors on the surface of target cells, triggering signaling pathways that lead to cell movement. This process is essential in immune surveillance, inflammation, and the development of immune responses. Kemokins also contribute to the recruitment of various immune cells including lymphocytes, monocytes, eosinophils, and neutrophils.

The dysregulation of kemokin production has been associated with various pathological conditions, including autoimmune diseases, chronic inflammatory disorders, and cancer. Due to their pivotal role in immune regulation, kemokins are considered potential targets for therapeutic intervention in various inflammatory and autoimmune diseases.

Research continues to explore the diverse functions of kemokins, their receptors, and their potential as biomarkers or therapeutic targets in disease management.
