Dynamic phosphatase-recruitment controls B-cell selection and oncogenic signaling
Biorxiv : the Preprint Server for Biology
|March 30, 2023
Summary
CD25 on B-cells, not as an IL2-receptor, forms an inhibitory complex to control B-cell receptor signaling. This finding impacts understanding of B-cell development, autoimmunity, and B-cell malignancies like leukemia and lymphoma.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- CD25 surface expression increases during B-cell receptor (BCR) signaling and antigen encounter.
- CD25 is known as an IL2-receptor chain on T and NK cells, but its role on B-cells was unclear.
- Increased CD25 expression is observed in B-cell leukemia (B-ALL) and lymphoma.
Conclusions:
- CD25 functions as a crucial regulator of BCR signaling feedback on B-cells, distinct from its role in the IL2 receptor.
- CD25 plays opposing roles in B-cell malignancies, with high expression correlating with poor outcomes in B-ALL and favorable outcomes in lymphoma.
- CD25's phosphatase-recruiting function is essential for preventing autoimmunity and controlling oncogenic signaling in B-cell cancers.

Amplifying Signals via Enzymatic Cascade
8.6K
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...

mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Receptor Downregulation in MVBs
2.1K
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...

Interactions Between Signaling Pathways
6.3K
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...

PI3K/mTOR/AKT Signaling Pathway
3.8K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

Mitogens and the Cell Cycle
6.6K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
