Summary
Immune checkpoint inhibitors (ICIs) improve cancer therapy, but low response rates persist. Understanding T-cell receptor and immune checkpoint signaling kinetics offers new strategies to enhance ICI efficacy.
Area of Science:
- Immunology
- Cancer Biology
- Computational Biology
Background:
- Immune checkpoint inhibitors (ICIs) targeting CTLA-4 and PD-1 are crucial cancer therapeutics.
- Despite advances, response rates for many cancers remain suboptimal, necessitating improved therapeutic strategies.
Purpose of the Study:
- To review T-cell receptor (TCR) signaling and its intersection with immune checkpoint (IC) signaling pathways.
- To highlight the kinetic regulation of these pathways by ICs and its implications for ICI efficacy.
Main Methods:
- Review of current literature on TCR and IC signaling.
- Focus on spatiotemporal dynamics and kinetic regulation.
- Integration of insights from computational modeling and advanced experimental techniques.
Main Results:
- Immune checkpoints modulate TCR signaling, impacting T-cell activation.
- Kinetic regulation of signaling pathways by ICs is a critical factor in ICI response.
- Spatiotemporal dynamics offer molecular insights into ICI mechanisms.
Conclusions:
- Understanding the dynamic interplay between TCR and IC signaling is key to improving ICI efficacy.
- Targeting kinetic aspects of immune checkpoints presents novel therapeutic opportunities.
- Advanced modeling and experimental methods are crucial for deciphering these complex interactions.

01:19Interactions Between Signaling Pathways
6.9K
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...

01:22T Cell Activation and Clonal Selection
14.1K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

01:20The JAK-STAT Signaling Pathway
10.5K
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...

01:22Amplifying Signals via Enzymatic Cascade
15.5K
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...

01:15Receptor Downregulation in MVBs
2.5K
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...

01:07Cell Signaling Feedback Loops
7.0K
Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...
