Conserved multisensory integration of social cues in the thalamus.

The recognition of conspecifics, animals of the same species, and keeping track of changes in the social environment is essential to all animals. While molecules, circuits, and brain regions that control social behaviors across species are studied in-depth, the neural mechanisms that enable the recognition of social cues are largely obscure. Recent evidence suggests that social cues across sensory modalities converge in a thalamic area conserved across vertebrates.

Duchenne muscular dystrophy (DMD), an X-linked neuromuscular disorder, characterised by progressive immobility, chronic inflammation and premature death, is caused by the loss of the mechano-transducing signalling molecule, dystrophin. In non-contracting cells, such as neurons, dystrophin is likely to have a functional role in synaptic plasticity, anchoring post-synaptic receptors. Dystrophin-expressing hippocampal neurons are key to cognitive functions such as emotions, learning and the consolidation of memories.

Previous studies have shown that arachidonoyl-lysophosphatidylinositol (LPI-20:4) produced an increase in the inflammatory mediators NLPR3 (inflammasome - 3 marker) and IL-1b in neurons from both rat dorsal root ganglion (DRG) and hippocampal cultures. Because LPI is comprised of a family of lipid structures that vary in fatty acyl composition, the current work examined neuroinflammatory responses to various LPI structures in DRG and hippocampal cultures as assessed by high content fluorescent imaging.

Nitric oxide (NO) is an essential molecule in biomedicine, recognized for its antibacterial properties, neuronal modulation, and use in inhalation therapies. The effectiveness of NO-based treatments relies on precise control of NO concentrations tailored to specific therapeutic needs. Electrochemical generation of NO (E-NOgen) via nitrite (NO ) reduction offers a scalable and efficient route for controlled NO production, while also addressing environmental concerns by reducing NO pollution and maintaining nitrogen cycle balance.
