Monitoring the activity of the central nervous system with the 14C-2-deoxyglucose method of Sokoloff was utilized to explore the possibility to develop a model for the study of central nervous system reaction to peripheral trauma. Preliminary evidence indicates that the activation caused by tactile stimuli to one hindlimb nerve is that expected from earlier physiologic studies. However, an increase of stimulation intensity to recruit nociceptive (pain) fibers seems to abolish the changes, indicating that inhibitory systems have been activated.

Dural perforation and life-threatening central nervous system complications associated with septic arthritis of the lumbar facet joint: illustrative case.

Background: Septic arthritis of the lumbar facet joint (SALFJ) is a rare condition that can lead to serious complications. The authors present an uncommon case in which SALFJ resulted in bacterial meningitis (BM) with hydrocephalus and pyogenic ventriculitis, causing a disturbance of consciousness. Reports describing perforation of the dura mater by an epidural abscess are rare, and the present case offers valuable insights into the management of complex and severe complications arising from SALFJ.

Some animals can regenerate large missing regions of their nervous system, requiring mechanisms to restore the pattern, numbers, and wiring of diverse neuron classes. Because injuries are unpredictable, regeneration must be accomplished from an unlimited number of starting points. Coordinated regeneration of neuron-glia architecture is thus a major challenge and remains poorly understood.

The endocannabinoid system (ECS), regulating such processes as energy homeostasis, inflammation, and muscle function, centers around cannabinoid receptors, including CB1. These receptors are mainly located in the central nervous system and skeletal muscles. Hyperactivity of CB1 receptors is linked to metabolic disorders and chronic inflammation, highlighting their potential as therapeutic targets for muscle hypertrophy and metabolic health.

This proceedings article summarizes the inaugural "T Cells in the Brain" symposium held at Columbia University. Experts gathered to explore the role of T cells in neurodegenerative diseases. Key topics included characterization of antigen-specific immune responses, T cell receptor (TCR) repertoire, microbial etiology in Alzheimer's disease (AD), and microglia-T cell crosstalk, with a focus on how T cells affect neuroinflammation and AD biomarkers like amyloid beta and tau.
