Insights

Immune cells use cytokines to communicate, triggering signal pathways like Jak-Stat. This review details signal transduction via class II cytokine receptors, including interferons and interleukin-10.

Area of Science:

  • Immunology
  • Cellular Biology
  • Molecular Signaling

Background:

  • Immune system cells communicate via cell-to-cell contact or mediators like cytokines.
  • Cytokines transmit signals through specific cell surface receptors, initiating intracellular signal transduction.
  • Signal transduction pathways regulate diverse biological activities essential for immune responses.

Purpose of the Study:

  • To review the Janus kinase-Signal transducer and activator of transcription (Jak-Stat) pathway.
  • To detail signal transduction through class II cytokine receptors.
  • To discuss related molecules including tissue factor and novel receptors.

Main Methods:

  • Review of existing literature on cytokine signaling and the Jak-Stat pathway.
  • Detailed description of signal transduction mechanisms for specific cytokine receptors.
  • Discussion of molecular complexes and receptor families.

Main Results:

  • The Jak-Stat pathway is a key mechanism for signal transduction initiated by cytokine binding to class II receptors.
  • Specific examples include signal transduction for Type I interferons (IFN-alpha, IFN-beta, IFN-omega), Type II interferon (IFN-gamma), and interleukin-10 (IL-10).
  • The study also addresses the tissue factor-factor VIIa complex and new class II cytokine receptor family members.

Conclusions:

  • The Jak-Stat pathway is crucial for mediating the biological effects of various cytokines.
  • Understanding signal transduction through class II cytokine receptors provides insight into immune regulation.
  • Further research into related molecular complexes and receptors can uncover new aspects of immune signaling.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Amplifying Signals via Second Messengers

Many receptor binding ligands are hydrophilic; they do not cross the cell membrane but bind to cell-surface receptors. Thus, their message must be relayed by second messengers present in the cell cytoplasm. There are several second messenger pathways, each with its own way of relaying information. For example, the G protein-coupled receptors can activate both phosphoinositol and cyclic AMP (cAMP) second messenger pathways. The phosphoinositol pathway is active when the receptor induces...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
