Summary
B cell activation involves metabolic reprogramming, crucial for proliferation and survival. The PI3K signaling pathway integrates receptor signals with cell metabolism, nutrient uptake, and biosynthesis.
Area of Science:
- Immunology
- Cell Biology
- Metabolic Signaling
Background:
- B cell growth and proliferation depend on B cell receptor and cytokine signaling.
- The PI3K signaling pathway is vital for B cell activation, differentiation, and survival.
- Activated B cells reprogram metabolism to meet energetic and biosynthetic needs.
Purpose of the Study:
- To review metabolic changes in activated B cells.
- To discuss B cell adaptation strategies under metabolic stress.
- To highlight the role of PI3K signaling in B cell metabolism.
Main Methods:
- Literature review of B cell signaling and metabolism.
- Analysis of PI3K pathway's role in B cell metabolic regulation.
- Discussion of nutrient acquisition, utilization, and biosynthesis in B cells.
Main Results:
- Activated B cells exhibit significant metabolic reprogramming.
- PI3K signaling integrates external stimuli with internal metabolic processes.
- B cells employ strategies to adapt to metabolic stress during activation.
Conclusions:
- PI3K signaling is a central regulator of B cell metabolism and activation.
- Understanding B cell metabolic adaptation is key to controlling immune responses.
- Metabolic reprogramming is essential for B cell function and survival.

01:22PI3K/mTOR/AKT Signaling Pathway
6.1K
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...

01:31The Intrinsic Apoptotic Pathway
9.1K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

01:11IP3/DAG Signaling Pathway
15.6K
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...

03:03mTOR Signaling and Cancer Progression
5.0K
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.

01:20The JAK-STAT Signaling Pathway
13.7K
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...

01:28Insulin: The Receptor and Signaling Pathways
5.6K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...
