Classic experiments with peripheral sympathetic neurons established an absolute dependence upon NGF for survival. A forgotten problem is how these become resistant to deprivation of trophic factors. The question whether and can survive in the absence support. However, mechanism not understood switch their phenotype lose on factors, such as BDNF. Here, we approach by considering requirements support hippocampal from central nervous system. We developed cellular assays assess factor dependency identified factors that rescue They include enhanced expression a subunit receptor (Neurotrophin Receptor Homolog, NRH) increase glucocorticoid neurons. results are significant since levels activity responsible many neuropsychiatric conditions. Resistance may be relevant underlying basis longevity, well important element preventing neurodegeneration.

Chronic pain and mental health disorders, such as depression anxiety, frequently co-occur share underlying mechanisms involving neuronal excitability synaptic transmission. The inwardly rectifying potassium channel 4.1 (Kir4.1), predominantly expressed in glial cells, is crucial for maintaining extracellular glutamate homeostasis. Dysregulation of Kir4.1 leads to altered activity, contributing both chronic disorders. In pain, downregulation impairs buffering clearance, increasing enhancing signaling through peripheral central sensitization. impaired function disrupts neurotrophic factor secretion neuroinflammatory pathways, leading mood disturbances. This review primarily summarizes findings from preclinical studies examine the relationship between pathogenesis discussing its molecular structure, expression patterns, functional roles. Furthermore, we explore therapeutic strategies targeting Kir4.1, including pharmacological modulators gene therapy approaches, emphasizing potential a novel target.

Abstract Satellite glial cells are important for proper neuronal function of primary sensory neurons which they provide homeostatic support. Most research on satellite cell has been performed with in vitro studies, but recent advances calcium imaging and transgenic mouse models have enabled this first vivo study single-cell inflammation neuropathic pain. We found that naïve conditions, do not respond a time-locked fashion to firing. In painful inflammatory states, we detected signals subset cells, only suprathreshold stimulation the sciatic nerve. Surprisingly, therefore, conclude most seem develop at arbitrary intervals directly linked activity patterns. More line expectations, our experiments also revealed number active was increased under conditions or nerve injury. This could reflect requirement support across dorsal root ganglion neuron populations, more during such states.

Neuropeptide Y (NPY) is best known for its effects in the brain as an orexigenic and anxiolytic agent reducing energy expenditure. NPY also co-expressed with norepinephrine (NE) sympathetic neurons. Although generally considered to modulate noradrenergic responses, specific roles autonomic physiology remain under-appreciated. Here, we show that sympathetic-derived essential metabolic cardiovascular regulation mice. NE are 90% of prevertebral neurons only 43% paravertebral NPY-expressing primarily innervate blood vessels peripheral organs. Sympathetic-specific deletion elicits pronounced defects mice, including reductions insulin secretion, glucose tolerance, cold pupil size elevated heart rate, while notably, however, basal pressure was unchanged. These findings provide insight into target tissue-specific functions derived from imply potential involvement diseases.

Nerve signaling within the tumor microenvironment (TME) plays a critical role in initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior activation upon injury cancer onset, this review specifically focuses on how sympathetic nerves rewire TME. Within tumors, closely interact with various TME components, combined often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes. In turn, such as myeloid cells, lymphoid extracellular matrix (ECM), endothelial associated fibroblasts (CAFs), Schwann secrete neurotrophic axon guidance factors that influence both outgrowth cell behavior, further exacerbating progression metastasis.

Abstract Ventricular arrhythmias in cardiac channelopathies are linked to autonomic triggers, which sub-optimally targeted current management strategies. Improved molecular understanding of and cellular signalling could refine therapies target the specific pathways relevant aetiologies as well central nervous system centres involved regulation. This review summarizes key anatomical physiological aspects its impact on ventricular primary inherited arrhythmia syndromes. Proarrhythmogenic effects potential therapeutic targets defined conditions including Brugada syndrome, early repolarization long QT catecholaminergic polymorphic tachycardia will be examined. Pharmacological interventional neuromodulation options for these discussed. Promising new include inhibitory excitatory G-protein coupled receptors, neuropeptides, chemorepellents/attractants vagal sympathetic nuclei system. Novel strategies utilizing invasive non-invasive deep brain/brain stem stimulation rapidly growing field chemo-, opto-, or sonogenetics allowing cell-specific targeting reduce presented.
