Insights

Toll-like receptor (TLR) signaling requires strict regulation to prevent host damage. This review explores how post-translational modifications, including phosphorylation and ubiquitination, control TLR pathway activity.

Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Signaling

Background:

  • Toll-like receptor (TLR) signaling is crucial for innate immunity.
  • Dysregulated TLR responses can lead to severe host pathology.
  • Tight control mechanisms are essential for managing TLR-mediated immunity.

Purpose of the Study:

  • To review the role of post-translational modifications in regulating TLR signaling.
  • To highlight phosphorylation, ubiquitination, and de-ubiquitination as key regulatory events.
  • To discuss how these modifications impact TLR pathway components.

Main Methods:

  • Literature review of studies on TLR signaling and post-translational modifications.
  • Focus on phosphorylation, ubiquitination, and de-ubiquitination events.
  • Analysis of signaling molecules within TLR pathways.

Main Results:

  • Post-translational modifications represent a critical control layer for TLR signaling.
  • Phosphorylation and ubiquitination/de-ubiquitination dynamically regulate TLR pathway components.
  • These modifications fine-tune the immune response, preventing excessive or insufficient activation.

Conclusions:

  • Post-translational modifications are indispensable for maintaining homeostasis in TLR signaling.
  • Targeting these modifications offers potential therapeutic strategies for immune-related disorders.
  • Understanding these regulatory mechanisms is key to controlling TLR-mediated inflammation.

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
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 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...
