The changes elicited by ligand binding (or signal sensing) in a receptor give rise to a biochemical cascade, which is a chain of biochemical events known as a signaling pathway. When signaling pathways interact with one another they form networks, which allow cellular responses to be coordinated, often by combinatorial signaling events. [2]
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
In addition to its role in synaptic plasticity described above, PI3K-AKT signaling pathway also has an important role in brain growth, which is altered when PI3K signaling is disturbed. For example, intracranial volume is also associated with this pathway, in particular with AKT3 intronic variants. [39]
NMDA receptors are permeable to calcium ions, which can trigger intracellular signaling pathways that lead to changes in synaptic strength. [14] 2. AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors: These receptors mediate the majority of fast excitatory synaptic transmission in the brain.
These neurotransmitters bind to a variety of receptors on the postsynaptic cell membrane. In response to neurotransmitter binding, these postsynaptic receptors can undergo conformational changes that may open a transmembrane channel subunit either directly, or indirectly via a G-Protein signaling pathway.
An important feature of the second messenger signaling system is that second messengers may be coupled downstream to multi-cyclic kinase cascades to greatly amplify the strength of the original first messenger signal. [3] [4] For example, RasGTP signals link with the mitogen activated protein kinase (MAPK) cascade to amplify the allosteric ...
