Intracellular signaling mechanisms

The signals can be transmitted through gap junction for cells in direct contact or through the release of soluble factors in the extracellular media. 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.

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. These adapters activate other intracellular molecules such as IRAK1, IRAK4, TBK1, and IKKi that amplify the signal, eventually leading to the induction or suppression of genes that cause certain responses.

Intracellular signaling pathways are therefore increasingly being studied as targets for novel antiviral therapies. Theoretically, each host factor required for a step of the viral life cycle could represent a potential target, but cytotoxicity could be a major concern [ 3 ].

Understanding the signaling mechanisms in PDT may provide means to modulate the PDT effects at the molecular level and potentiate its antitumor effectiveness. An important phenomena that happens in the intracellular portion of signaling is signal amplification. 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.

will provide groundbreaking insights into those mechanisms that regulate cellular Intracellular signaling: Various agonist-triggered membrane receptors use inositol phospholipid hydrolysis as the first step of intracellular cascades that continue downstream via calcium and protein kinase C-mediated signaling. The membrane receptors activate a specific zinc-containing phospholipase C (EC3.1.4.3) that releases two signaling compounds: diacyl glycerol and inositol-1,4,5-triphosphate. Our research has characterized the intracellular stress signaling mechanism(s) that are involved in the up-regulated expression of genes encoding cyclooxygenase (COX2), interleukin (IL)-8, granulocyte macrophage colony stimulatory factor (GM-CSF), and transglutaminase (TGase)1 in UVB-exposed keratinocytes as well as in the stimulated transcription and/or translation of melanogenic factors, including microphthalmia-associated transcription factor (MITF), in stem cell factor (SCF)-treated Binding initiates a signaling pathway When a ligand binds to a cell-surface receptor, the receptor’s intracellular domain (part inside the cell) changes in some way.

Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately results in a cellular response.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used.

Signal molecules that can be released through various ways like membrane-diffusion, exocytosis or cell damage. In some cases the signal molecules remain attached with cell-surface, a mode that helps in juxtacrine signaling (discussed below).

Moreover, ligand–receptor binding is seldom connected to a single signaling pathway.
