Learn how signals are relayed inside a cell starting from the cell membrane receptor. The chains of molecules that relay intracellular signals are known as intracellular signal transduction pathways.

Virus vectors were pro- Intracellular Signaling. Intracellular signaling can induce a conformational change that disrupts the transmembrane domain interaction and extends the extracellular region, thereby exposing the ligand binding site and increasing ligand affinity [52–58]. From: Lung Epithelial Biology in the Pathogenesis of Pulmonary Disease, 2017. Related terms: Intracellular signaling is an important mechanism by which cells can respond to their environment and extracellular cues. Cells can sense their environment and modify gene expression, mRNA splicing, protein expression and protein modifications in order to respond to these extracellular cues. Intracellular signaling pathways are a source for drug target search not only in antiparasitic drug development but also in other fields including inflammation, neurodegeneration and cancer (Cunningham et al., 2008; Lugnier, 2006; Savai et al., 2010).

The first step in signaling is the binding of the first messenger to the cell surface receptor. The binding results in the activation of the receptor (via a change in x or conformation). The receptor can now react with the effectors (signaling proteins - enzymes or ion channels).

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.

The OXTR, a 7-transmembrane G protein-coupled receptor capable of binding to either Gα i or Gα q proteins, activates a set of signaling cascades, such as the MAPK, PKC, PLC, or CaMK pathways, which converge on transcription factors like CREB or MEF-2. The cellular response to OXT includes regulation of neurite outgrowth, cellular viability, and increased survival.

Intracellular Signaling In intracellular signaling the signals are transmitted across the membrane of cells. The intracellular component of signal propagation, also known as signal transduction, is receptor-specific. A given receptor will activate only very specific sets of downstream signaling components, thereby maintaining the specificity of the incoming signal inside the cell. Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in transcription, translation, protein modifications, enzyme activation, cellular metabolism, mitosis, and/or apoptosis. Intracellular Signalling Proteins, Volume 116, presents an overview of the current developments in mechanisms of intracellular signaling and involvement of these mechanisms in the development of a number of disorders and diseases. Impaired mitochondrial function and accumulation of DNA damage have been recognized as hallmarks of age-related diseases. Mitochondrial dysfunction initiates protective signalling mechanisms coordinated at nuclear level particularly by modulating transcription of stress signalling factors.
