Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.
A binary cell fate decision to be or not to be stomata is regulated by multiple peptide ligands, each triggering a unique subcellular dynamics of their shared receptor.
Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.
Glutamatergic projections from basolateral to central amygdala, implicated in neuropsychiatric disorders, develop rapidly during early postnatal period and their development is modulated via endogenously active kainate receptors.
In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.
