Erythrocyte signal transduction pathways and their possible functions
Current Opinion in Hematology
|March 1, 1997
Summary
Human red blood cells (erythrocytes) possess signaling pathways. These pathways may be remnants from precursor cells or enable erythrocytes to interact with other blood and vessel cells.
Area of Science:
- Hematology
- Cell biology
- Signal transduction
Background:
- Mature human erythrocytes possess various receptors and effectors.
- These components mediate signal transduction pathways, similar to those in nonerythroid cells.
Purpose of the Study:
- To investigate the potential roles of signaling pathways in mature erythrocytes.
- To explore if these pathways are vestiges or functional elements for cell-cell communication.
Main Methods:
- Analysis of erythrocyte surface receptors and intracellular signaling components.
- Comparison of erythrocyte signaling elements with those in precursor cells and other cell types.
Main Results:
- Erythrocytes exhibit a diverse array of signaling molecules.
- Some signaling components appear to be remnants from erythrocyte precursors.
- Other elements suggest a role in erythrocyte interactions with hematopoietic and endothelial cells.
Conclusions:
- Erythrocyte signaling machinery has dual origins: vestiges and functional adaptations.
- These functional pathways likely facilitate erythrocyte communication with other cells in the vascular system.

01:24Intracellular Signaling Cascades
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

01:19Interactions 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...

01:15Amplifying 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...
01:22Amplifying 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...
01:26Signal 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...
