Aqueous solubility of cystic fibrosis drug ivacaftor is ~200-fold lower, whereas the potency of its stimulatory effect on the CFTR channel is >100-fold higher, than reported, and is fully reversible.
Building on previous work (Huang et al., 2016), we show that translational control by p-eIF2α is a defense mechanism that prevents persistent cocaine-induced synaptic synaptic potentiation underlying compulsive drug seeking.
Enhanced glutamatergic synaptic plasticity in mesolimbic dopaminergic neurons may contribute to repeatedly stressed rats becoming more vulnerable to addiction.
The small molecule NMDA-receptor antagonist MK801 has been genetically targeted to specific cell types in brain tissue to examine the role of NMDA receptors in cocaine-induced synaptic plasticity.
Zebrafish mutants and human endothelial cell experiments reveal that GIPC family endocytic adaptors bind to the Semaphorin receptor PLEXIND1, a critical regulator of vascular development, to negatively modulate its signaling.
An in vivo drug screen of FDA-approved compounds in zebrafish identified host-directed therapies against mycobacterial infection, including the drug clemastine, which targets the P2RX7-inflammasome axis to enhance bacterial control.
Parvalbumin-containing inhibitory neurons are crucial for expression of plasticity in adult visual cortex that supports visual recognition memory, but not for expression of ocular dominance plasticity that results from monocular deprivation.
The conditional reduction of glutaminase in mouse dopamine neurons selectively attenuates glutamate cotransmission at phasic frequencies, revealing the role of dopamine neuron glutamate cotransmission in the attribution of motivational salience.
