1West China Second University Hospital, Sichuan University, Chengdu 610041, China.
Summary
Brain-derived neurotrophic factor (BDNF) protects neurons from hypoxia-induced toxicity by promoting cell growth and survival. BDNF activates key signaling pathways, including MAPK and CaMK, highlighting complex cellular crosstalk.
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Context:
- Brain-derived neurotrophic factor (BDNF) is abundant in brain tissue.
- BDNF functions as an activity-dependent neuronal survival factor.
- In vitro studies demonstrate BDNF's protective role against hypoxia-induced neurotoxicity in cortical neurons.
Purpose:
- To elucidate the cellular responses induced by BDNF.
- To investigate the signaling pathways activated by BDNF.
- To explore the cross-talk between BDNF-mediated signaling pathways.
Summary:
- BDNF promotes neuronal survival and prevents hypoxia-induced neurotoxicity.
- It triggers cellular responses including growth, survival, differentiation, and anti-apoptosis.
- BDNF primarily activates mitogen-activated protein kinase (MAPK) and Ca2+/calmodulin-dependent kinase (CaMK) signaling pathways.
- Complex cross-talk exists among these activated signaling pathways.
Impact:
- Provides insights into the neuroprotective mechanisms of BDNF.
- Highlights the role of MAPK and CaMK pathways in neuronal survival.
- Suggests potential therapeutic targets for neurological disorders involving neurotoxicity.

01:07MAPK Signaling Cascades
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
01:00Enzyme-linked Receptors
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

01:22PI3K/mTOR/AKT Signaling Pathway
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 rapamycin-insensitive companion...
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...

03:03mTOR Signaling and Cancer Progression
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.

01:42Microtubule Associated Proteins (MAPs)
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...
