BDNF/TrkB Signaling Inhibition Suppresses Astrogliosis and Alleviates Mechanical Allodynia in a Partial Crush Injury Model.

Neuropathic pain presents a formidable clinical challenge due to its persistent nature and limited responsiveness to conventional analgesic treatments. While significant progress has been made in understanding the role of spinal astrocytes in neuropathic pain, their contribution and functional changes following a partial crush injury (PCI) remain unexplored. In this study, we investigated structural and functional changes in spinal astrocytes during chronic neuropathic pain, employing a partial crush injury model.

Pharmacological Evidence Suggests That Slo3 Channel Is the Principal K Channel in Boar Spermatozoa.

Sperm ion channels are associated with the quality and type of flagellar movement, and their differential regulation is crucial for sperm function during specific phases. The principal potassium ion channel is responsible for the majority of K ion flux, resulting in membrane hyperpolarization, and is essential for sperm capacitation-related signaling pathways. The molecular identity of the principal K channel varies greatly between different species, and there is a lack of information about boar K channels.
