Juxtacrine signalling — thumb|Notch mediated juxtacrine signal between adjacent cells.In biology, juxtacrine signaling is a type of intercellular communication which is transmitted via oligosaccharide, lipid or protein components of a cell membrane and may affect either … Wikipedia
Signaling molecule — A signaling molecule is a chemical involved in transmitting information between cells. Such molecules are released from the cell sending the signal, cross over the gap between cells by diffusion, and interact with specific receptors in another… … Wikipedia

Cell signaling — is part of a complex system of communication that governs basic cellular activities and coordinates cell actions. [Witzany, G. (2000). Life: The Communicative Structure. Norderstedt, Libri BoD.] The ability of cells to perceive and correctly… … Wikipedia
Endocrine system — In physiology, the endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body. The endocrine system is in contrast to the exocrine system, which secretes its chemicals using … Wikipedia
Autocrine signalling — Autocrine signaling is a form of signaling in which a cell secretes a hormone, or chemical messenger (called the autocrine agent) that binds to autocrine receptors on the same cell, leading to changes in the cell. This can be contrasted with… … Wikipedia
Cell surface receptor — The seven transmembrane α helix structure of a G protein coupled receptor Cell surface receptors (membrane receptors, transmembrane receptors) are specialized integral membrane proteins that take part in communication between the cell and the… … Wikipedia
Cytokine — Cytokines (Greek cyto , cell; and kinos, movement) are small cell signaling protein molecules that are secreted by the glial cells of the nervous system and by numerous cells of the immune system and are a category of signaling molecules used… … Wikipedia

Ligand (biochemistry) — Myoglobin (blue) with its ligand heme (orange) bound. Based on PDB 1MBO For other uses of Ligand , see Ligand (disambiguation). In biochemistry and pharmacology, a ligand (from the … Wikipedia
Co-receptor — A co receptor is a cell surface receptor that binds a signalling molecule in addition to a primary receptor in order to facilitate ligand recognition and initiate biological processes, such as entry of a pathogen into a host cell. Contents 1 Co… … Wikipedia
