Summary
Immune checkpoint inhibitors, like anti-PD-L1/PD1 antibodies, are transforming cancer treatment. This review explores the crucial, yet understudied, intracellular signaling pathways regulated by PD1 and the effects of blocking these pathways.
Area of Science:
- Oncology
- Immunology
- Molecular Biology
Background:
- Immune checkpoint inhibitors (ICIs) are revolutionizing cancer therapy.
- Antibodies targeting PD-L1/PD1 interactions show high efficacy and low toxicity.
- The intracellular signaling pathways regulated by PD-L1 and PD1 remain poorly understood.
Purpose of the Study:
- To review current knowledge on PD1-dependent intracellular signaling pathways.
- To discuss the consequences of disrupting PD1 signal transduction in cancer treatment.
Main Methods:
- Literature review of PD1-dependent signaling.
- Analysis of the impact of PD1 pathway disruption.
Main Results:
- PD1 signaling regulates key intracellular pathways in T cells.
- Disruption of PD1 signaling can enhance anti-tumor immunity.
Conclusions:
- Understanding PD1 intracellular signaling is critical for optimizing cancer immunotherapy.
- Targeting PD1 pathways offers potential for improved cancer treatment strategies.

01:19Interactions Between Signaling Pathways
7.4K
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...

01:22Amplifying Signals via Enzymatic Cascade
18.7K
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...

01:20The JAK-STAT Signaling Pathway
13.3K
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...

01:15Amplifying Signals via Second Messengers
8.9K
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...

01:16TGF - β Signaling Pathway
10.7K
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...

01:11IP3/DAG Signaling Pathway
15.2K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...
