Microglial modulation of neuronal network function and plasticity.

Microglia are the resident immune cells of the central nervous system (CNS), which have been classically viewed as involved in CNS responses to damage and tissue repair. However, microglia are constantly sensing neuronal network activity and changes in the CNS milieu, establishing complex state-dependent microglia-neuron interactions that impact their functions. By doing so, microglia perform a wide range of physiological roles, including brain homeostasis maintenance, control of neural connectivity, network function modulation, as well as functional and morphological plasticity regulation in health and disease.

Synthesis of Enantiopure - and -Fused Octahydroisoindole-1-Phosphonic Acids from Octahydroisoindolones.

Phosphonic analogs of octahydroisoindole-1-carboxylic acids are bicyclic proline derivatives of interest in drug design and enzymatic mechanism studies. Here we report the stereoselective synthesis of the - and -fused octahydroisoindole system using oxazoloisoindolone lactam and 1,2-cyclohexanedicarboxylic anhydride as advanced chiral precursors, respectively, yielding enantiopure octahydroisoindolone intermediates with the desired stereochemistry at the ring junction. Finally, using these intermediates, the target (1,3a,7a)- and (1,3a,7a)-octahydroisoindole-1-phosphonic acids and their enantiomers were obtained with complete stereocontrol via highly diastereoselective addition of trimethyl phosphite to chiral -acyliminium ions as the key step.

The optimal color space enables advantageous smartphone-based colorimetric sensing.

Smartphone-based colorimetric (bio)sensing is a promising alternative to conventional detection equipment for on-site testing, but it is often limited by sensitivity to lighting conditions. These issues are usually avoided using housings with fixed light sources, increasing the cost and complexity of the on-site test, where simplicity, portability, and affordability are a priority. In this study, we demonstrate that careful optimization of color space can significantly boost the performance of smartphone-based colorimetric sensing, enabling housing-free, illumination-invariant detection.
