Second messengers trigger physiological changes at cellular level such as proliferation, differentiation, migration, survival, apoptosis and depolarization. They are one of the triggers of intracellular signal transduction cascades.

2022年5月14日 · Second messengers are molecules that relay signals received at receptors on the cell surface — such as the arrival of protein hormones, growth factors, etc. — to target molecules in the cytosol and/or nucleus. But in addition to their job as relay molecules, second messengers serve to greatly amplify the strength of the signal. Binding of a ...

第二信使（Second messenger）在生物学里是胞内信号分子，负责细胞内的信号转导以触发生理变化，如增殖， 细胞分化 ，迁移，存活和细胞凋亡。因此第二信使是细胞内的信号转导的启动组成部件之一。

第二信使（英语：Second messenger）在生物学里是胞内信号分子，负责细胞内的信号转导以触发生理变化，如 增殖 （ 英语 ： Cell growth ） 、细胞分化、迁移、存活和细胞凋亡。

Second messengers are small molecules and ions that relay signals received by cell-surface receptors to effector proteins. They include a wide variety of chemical species and have diverse properties that allow them to signal within membranes (e.g., ...

The Second Messenger System is an intracellular mechanism mediated by calcium ions that brings about changes in genes and proteins involved in memory storage, influencing the formation of dendritic spines and participating in dendritic plasticity. AI generated definition based on: The Biology of Thought, 2015

Second messenger, molecule inside cells that acts to transmit signals from a receptor to a target. The term second messenger was coined upon the discovery of these substances in order to distinguish them from hormones and other molecules that function outside the cell as “first messengers” in the

2025年1月12日 · Second messengers are indispensable in orchestrating cellular communication, bridging the gap between external cues and the cell’s internal machinery. When a signaling molecule binds to a receptor, it sets off a chain reaction that culminates in the production of second messengers.

Second messenger systems provide incredibly powerful mechanisms for the transformation of stimuli from merely electrical and biochemical signals into stable, long-lasting, and memory-specific neuronal representations. The brain uses the second messengers, calcium and cyclic adenosine monophosphate (cAMP), to effectively transmit synaptic ...

Second messenger systems provide incredibly powerful and specific ways for stimuli to be transformed from merely electrical and biochemical processes into stable, long-lasting, and memory-specific neuronal representations. This chapter focuses on the ways in which neurons use second messenger systems, with particular emphasis on calcium and ...
