Plant meristems: A ménage à trois to end it all

Ménage à trois

Ménage à trois

Glioblastoma is an aggressive primary brain cancer. Given our interest in novel immunotherapies, we have recently shown that inhibiting CTLA-4, PD-L1 and IDO results in a dramatic survival advantage in mice with brain tumors. Our preclinical study supports the rapid translation of this approach into phase I clinical trial.

GABAA, NMDA and AMPA receptors: a developmentally regulated 'ménage à trois'.

The main ionotropic receptors (GABAA, NMDA and AMPA) display a sequential participation in neuronal excitation in the neonatal hippocampus. GABA, the principal inhibitory transmitter in the adult CNS, acts as an excitatory transmitter in early postnatal stage. Glutamatergic synaptic transmission is first purely NMDA-receptor based and lacks functional AMPA receptors. Therefore, initially glutam...

Synaptic Ménage à Trois

Regulation of neurotransmitter receptor localization is critical for synaptic function and plasticity. In this issue of Neuron, Matsuda and colleagues (Matsuda et al., 2016) uncover a transsynaptic complex consisting of neurexin-3, C1q-like proteins, and kainate receptors that drives glutamate receptor clustering at hippocampal synapses.

Acetaldehyde, Motivation and Stress: Behavioral Evidence of an Addictive ménage à trois

Acetaldehyde (ACD) contributes to alcohol's psychoactive effects through its own rewarding properties. Recent studies shed light on the behavioral correlates of ACD administration and the possible interactions with key neurotransmitters for motivation, reward and stress-related response, such as dopamine and endocannabinoids. This mini review article critically examines ACD psychoactive propert...
