CRMP2 conditional knockout changes axonal function and ultrastructure of axons in mice corpus callosum.

Collapsin response mediator protein 2 (CRMP2) is a member of a protein family, which is highly involved in neurodevelopment, but most of its members become heavily downregulated in adulthood. CRMP2 is an important factor in neuronal polarization, axonal formation and growth cone collapse. The protein remains expressed in adulthood, but is more region specific.

Parabrachial Interleukin-6 Reduces Body Weight and Food Intake and Increases Thermogenesis to Regulate Energy Metabolism.

Chronic low-grade inflammation and increased serum levels of the cytokine IL-6 accompany obesity. For brain-produced IL-6, the mechanisms by which it controls energy balance and its role in obesity remain unclear. Here, we show that brain-produced IL-6 is decreased in obese mice and rats in a neuroanatomically and sex-specific manner.

A single dose of cocaine potentiates glutamatergic synaptic transmission onto locus coeruleus neurons.

The brainstem locus coeruleus (LC), the primary norepinephrinergic (NE) nucleus in the brain, has been implicated in the abuse of drugs such as opioids. However, whether and how the LC-NE system is involved in cocaine addiction remains elusive. Here, we demonstrated cocaine-evoked synaptic plasticity of glutamatergic transmission onto LC neurons as one of the earliest traces occurring after a single injection of cocaine.
