Article Abstract
Traumatic brain injury (TBI) is major neurological burden globally, and effective treatments are urgently needed. TBI is characterized by a reduction in energy metabolism and synaptic function that seems a primary cause of neuronal dysfunction. R13, a small drug and BDNF mimetic showed promising results in improving spatial memory and anxiety-like behavior after TBI. Additionally, R13 was found to counteract reductions in molecules associated with BDNF signaling (p-TrkB, p-PI3K, p-AKT), synaptic plasticity (GluR2, PSD95, Synapsin I) as well as bioenergetic components such as mitophagy (SOD, PGC-1α, PINK1, Parkin, BNIP3, and LC3) and real-time mitochondrial respiratory capacity. Behavioral and molecular changes were accompanied by adaptations in functional connectivity assessed using MRI. Results highlight the potential of R13 as a therapeutic agent for TBI and provide valuable insights into the molecular and functional changes associated with this condition.

Microglia are resident immune cells of brain, which serves as a driver of the innate immunity within the central nervous system (CNS). The NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome is a multiprotein complex that is critical component of the innate immunity and hyperactivation of inflammasome under various conditions contributing to the pathogenesis of neurodegenerative diseases (NDs). 7,8-Dihydroxyflavone (7,8-DHF) have become the focus of attention in studies on NDs due to exert its neurotrophic effects in the CNS.

Microglia-mediated neuroinflammation plays a crucial role in memory and cognitive deficits and the development of early mild cognitive impairment (MCI) associated with Alzheimer's disease (AD). Paeoniflorin (PF) has been established as an effective antioxidant and anti-apoptotic agent. This study investigated the protective effects of PF on neuroinflammation, amyloidogenesis, and memory impairments in lipopolysaccharide (LPS)-stimulated BV-2 microglial cells and a C57BL/6 J amnesic mouse model.

The Vps10p-domain receptors SorCS1-3 have been repeatedly associated with the development of neurological and psychiatric disorders. They have emerged as key regulators of synaptic activity and neurotrophic signaling, but the underlying molecular mechanism remains poorly understood. Here we report that the SorCS2 intracellular domain (ICD) contains a triple serine motif that potentially functions as a signaling switch to induce intracellular signaling in hippocampal neurons.

Alzheimer's disease (AD) remains one of the most debilitating neurodegenerative disorders, with its pathological hallmark being progressive cognitive decline and memory loss. Recent research has illuminated the crucial role of the brain-derived neurotrophic factor (BDNF) in the central nervous system (CNS), highlighting its impact on neurogenesis, synaptic plasticity, and neuronal survival. Dysregulation of the BDNF signaling axis, particularly the imbalance between its precursor form and mature BDNF, is strongly implicated in the pathophysiology of AD.

Among neurotrophins, including nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4/5), BDNF has been extensively studied for its physiological role in cell survival and synaptic regulation in the central nervous system's (CNS's) neurons. BDNF binds to TrkB (a tyrosine kinase) with high affinity, and the resulting downstream intracellular signaling cascades play crucial roles in determining cell fate, including neuronal differentiation and maturation of the CNS neurons. It has been well demonstrated that the downregulation/dysregulation of the BDNF/TrkB system is implicated in the pathogenesis of neurologic and psychiatric disorders, such as Alzheimer's disease (AD) and depression.
