Abstract:
BDNF and its associated tropomyosin-related kinase receptor B (TrkB) nurture vessels and nerves serving the heart. However, the direct effect of BDNF/TrkB signaling on the myocardium is poorly understood. Here we report that cardiac-specific TrkB knockout mice (TrkB−/−) display impaired cardiac contraction and relaxation, showing that BDNF/TrkB signaling acts constitutively to sustain in vivo myocardial performance. BDNF enhances normal cardiomyocyte Ca2+ cycling, contractility, and relaxation via Ca2+/calmodulin-dependent protein kinase II (CaMKII). Conversely, failing myocytes, which have in

Abstract:
Brain-derived neurotrophic factor (BDNF) binds to its cell surface receptor TrkB to regulate differentiation, development, synaptic plasticity, and functional maintenance of neuronal cells. Binding of BDNF triggers TrkB dimerization and autophosphorylation, which provides docking sites for adaptor proteins to recruit and activate downstream signaling molecules. The molecular mechanisms underlying BDNF–TrkB endocytic trafficking crucial for spatiotemporal control of signaling pathways remain to be elucidated. Here we show that retrolinkin, a transmembrane protein, interacts with endophilin A1 a

Brain-derived neurotrophic factor (BDNF) and TrkB receptor signaling contribute to the central nervous system (CNS) control of energy balance. The role of hindbrain BDNF/TrkB receptor signaling in energy balance regulation is examined here.

To localize the neurons mediating the energy balance effects of hindbrain ventricle-delivered BDNF, ventricle subthreshold doses were delivered directly to medial nucleus tractus solitarius (mNTS). mNTS BDNF administr

Abstract Pediatric high-grade gliomas (pHGG) are a devastating group of diseases that urgently require novel therapeutic options. We have previously demonstrated that pHGGs hijack mechanisms of brain development and plasticity to their advantage. Here, we investigated the role of microenvironmental BDNF on pediatric gliomas, independent of the NTRK fusion events commonly identified in infant HGG.

In a combined animal and human study, we have previously found that a 5-day treatment that enhances cortical plasticity also facilitates brain-derived neurotrophic factor (BDNF)-tyrosine receptor kinase B (TrkB) signaling and increases activated TrkB and N-methyl-d-aspartate receptor (NMDAR) association in both the cortex and the peripheral lymphocytes.

Abstract:
Brain-derived neurotrophic factor (BDNF) and its receptor tropomyosin-related kinase receptor type B (TrkB) are widely distributed in multiple regions of the human brain. Specifically, BDNF/TrkB is highly expressed and activated in the dopaminergic neurons of the substantia nigra and plays a critical role in neurophysiological processes, including neuro-protection and maturation and maintenance of neurons. The activation as well as dysfunction of the BDNF-TrkB pathway are associated with neurodegenerative diseases. The expression of BDNF/TrkB in the substantia nigra is significantly reduced in

Here we show that α-Syn selectively interacts with TrkB receptors and inhibits BDNF/TrkB signaling, leading to dopaminergic neuronal death. α-Syn binds to the kinase domain on TrkB, which is negatively regulated by BDNF or Fyn tyrosine kinase.

Abstract:
Muscles are the enriched reservoir of proteins in the body. During any workout or exercise, the demand in the form of energy is essentially required by the muscle. Energy expenditure of skeletal muscle is more dependent on the type of demand. There is particular homeostasis within the body that avoid surplus energy expenditure and this prevents any muscle loss. Muscle atrophy is termed as the loss of skeletal muscle mass due to immobility, malnutrition, medications, aging, cancer cachexia, variety of injuries or diseases that impact the musculoskeletal or nervous system. Hence, atrophy within the skeletal muscle initiates further cause fatigue, pain, muscle weakness, and disability in human subjects. Therefore, starvation and reduced muscle mass further initiate numerous signaling pathways including inflammatory, antioxidant signaling, mitochondria bio-energetic failure, AMP-activated protein kinase (AMPK), Sirtuin 1(SIRT1), BDNF/TrkB/PKC, Autophagy, ubiquitin-proteasome systems, etc. Here, in this chapter, we will mention molecular mechanisms involved in therapeutic targets and available Pharmacological Interventions with the latest updates.

Abstract:
Diet impacts anxiety in two main ways. First anxiety can be caused by deficiencies in antioxidants, neurotransmitter precursors, amino acids, cations and vitamins and other cofactors. Second, anxiety can be reduced by anxiolytic nutraceuticals which are food molecules that bind to molecular targets of the amygdala and the hypothalamus-pituitary–adrenal axis (HPA-axis). Anxiety is a feeling of fear that arises from a perceived threat and can be a beneficial coping mechanism to threats and stressors. However excessive anxiety is a disorder that interferes with healthy responses to stressors. The amygdala is responsible for assigning value to a threat or stressor and triggering the HPA-axis to support the body wide system responses to the threat. The amygdala also communicates with the neuroplastic learning and memory centers of the hippocampus to fix or set a learned value to the threat. Interestingly, many anxiolytic nutraceuticals that show benefits in human clinical trials have neurotrophic activity and increase neuronal plasticity. Moreover, anxiolytic nutraceuticals either act like the neurotrophins, nerve growth factor (NGF), brain derived neurotrophic factor (BDNF and neurotrophin-3 (NT3) by either directly binding to or potentiating the tyrosine receptor kinase (TRK) family of receptors (TRKA, TRKB and TRKC) and activating the ERK1/2 signal transduction pathway associated with neurite outgrowth and neural plasticity. This chapter will explore the neuritogenic activity of clinically proven plant-based anxiolytic nutraceuticals and examine the commonality of TRKA-C receptors and the ERK1/2 signaling pathway in the pharmacological and nutraceutical treatment of anxiety disorders.
