Jelzanyagokat, which translates to "signaling substances" or "signaling molecules," refers to a diverse group of chemical compounds that cells use to communicate with each other. This intercellular communication is fundamental to the proper functioning of multicellular organisms, coordinating various physiological processes.

These substances can be classified based on their origin, target, and mode of action. Hormones, for example, are signaling molecules produced by endocrine glands that travel through the bloodstream to target cells far away. Neurotransmitters are released by neurons at synapses and act locally on adjacent cells. Cytokines are signaling molecules involved in immune responses and inflammation. Growth factors stimulate cell growth, proliferation, and differentiation.

The process of cell signaling typically involves three key components: the signaling molecule itself, a receptor on the target cell that binds to the molecule, and a series of intracellular events triggered by this binding. These events can lead to changes in gene expression, enzyme activity, or cell shape, ultimately altering the behavior of the target cell.

Dysregulation of signaling pathways can lead to various diseases, including cancer, diabetes, and autoimmune disorders. Research into jelzanyagokat is crucial for understanding these diseases and developing targeted therapies.
