WebReceptors allow the cells to recognize specific ligands and to receive extracellular messages. They can be classified into five families: 1) receptors for lipidic or lipophilic ligands; 2) the seven transmembrane receptors which mediate their messages by transduction through the activation of G-proteins, effectors and second messengers to … WebJul 9, 2014 · The immune system does much more than simply protect us from infection. It can tell the difference between the body's own cells and those belonging to invaders. Immune system cells can tell the difference …

WebJun 22, 2024 · 1. Reception: A cell detects a signaling molecule from the outside of the cell. A signal is detected when the chemical signal (also known as a ligand) binds to a receptor protein on the surface of the cell or inside the cell. 2. Transduction: When the signaling molecule binds the receptor it changes the receptor protein in some way. Webreceptor: [ re-sep´tor ] 1. a molecule on the cell surface (cell-surface or membrane receptor) or within a cell, usually in its nucleus (nuclear receptor) that recognizes and binds with specific molecules, producing some effect in the cell; e.g., the cell-surface receptors of immunocompetent cells that recognize antigens, complement ...
