The intracellular signaling network is composed of numerous signaling pathways, which transmit extracellular signals into the cells to influence cellular metabolism and gene expression, leading to changes in proliferation, differentiation, transformation, and programmed cell death.

The intracellular signaling mechanisms by which cholecystokinin (CCK) and other secretagogues regulate pancreatic acinar function are more complex than originally realized. CCK couples through heterotrimeric G proteins of the G family to lead to an increase in intracellular free Ca, which shows spatial and temporal patterns of signaling. The actions of Ca are mediated in part by activation of

Signaling pathways are often very complex because of the interplay between different proteins. Intracellular signaling mechanisms and activities of human herpesvirus 8interleukin-6. Chen D(1), Sandford G, Nicholas J. Author information: (1)Department of Oncology, Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins University School of Medicine, Baltimore, Maryland 21287, USA. Human herpesvirus 8 (HHV-8)-encoded viral interleukin-6 (vIL-6) has beenimplicated as a key factor in virus-associated neoplasia because of itsproproliferative and survival effects and also in view of its Various neuropeptides and neurotransmitters impinging on SCN neurons can activate receptors and ion channels on the plasma membrane to trigger intracellular signaling events. Activation of G-protein coupled receptors (GPCRs) can signal via G s , G i , and G q proteins to activate adenylyl cyclase (AC), inhibit AC, or activate phospholipase Cβ (PLCβ), respectively. In an attempt to further investigate the activation of eosinophils induced by IL-33, we elucidated the intracellular signaling mechanisms regulating the survival, adhesion, and cytokine and An important phenomena that happens in the intracellular portion of signaling is signal amplification.

Intracellular Signaling Mechanisms Involved in the Biological Effects of the Xanthophyll Carotenoid Astaxanthin to Prevent the Photo-aging of the Skin in a Reactive Oxygen Species Depletion-independent Manner: The Key Role of Mitogen and Stress-activated Protein Kinase 1 Genji Imokawa*1,2 Intracellular signaling enables a modification of the incoming signals or stimuli in terms of amplification, sensitivity, and divergence. Moreover, ligand–receptor binding is seldom connected to a single signaling pathway. Intracellular signals can diverge and address different pathways which furthermore may interact with each other (cross talk). 2005-09-21 Intracellular Signaling Mechanisms Involved in the Biological Effects of the Xanthophyll Carotenoid Astaxanthin to Prevent the Photo‐aging of the Skin in a Reactive Oxygen Species Depletion‐independent Manner: The Key Role of Mitogen and Stress‐activated Protein Kinase 1 2012-05-21 2004-09-20 Apart from these intracellular signals, the damaged cells send intercellular signals to their neighbour cells. The signals can be transmitted through gap junction for cells in direct contact or through the release of soluble factors in the extracellular media.

During signal amplification, a few number of receptors are initially activated. The intracellular response results in multiple secondary messengers to be activated, thereby amplifying the initial signal. Intracellular signaling mechanisms in photodynamic therapy.
