Cerebellin-2 regulates a serotonergic dorsal raphe circuit that controls compulsive behaviors.

Mol Psychiatry 2021 Jun 22. Epub 2021 Jun 22.

Department of Molecular Cellular Physiology and Howard Hughes Medical Institute, Stanford University School of Medicine, 265 Campus Dr., Stanford, CA, 94305, USA.

Cerebellin-1 (Cbln1) and cerebellin-2 (Cbln2) are secreted glycoproteins that are expressed in distinct subsets of neurons throughout the brain. Cbln1 and Cbln2 simultaneously bind to presynaptic neurexins and postsynaptic GluD1 and GluD2, thereby forming trans-synaptic adhesion complexes. Genetic associations link cerebellins, neurexins and GluD's to neuropsychiatric disorders involving compulsive behaviors, such as Tourette syndrome, attention-deficit hyperactivity disorder (ADHD), and obsessive-compulsive disorder (OCD).

Fluoxetine for Stroke: A Mixed Bag of Outcomes.

J Clin Psychiatry 2021 Jun 8;82(3). Epub 2021 Jun 8.

Department of Clinical Psychopharmacology and Neurotoxicology, National Institute of Mental Health and Neurosciences, Bangalore, India.

Stroke is the leading neurologic cause of burden operationalized in terms of disability-adjusted life-years. After stroke, motor deficits, cognitive deficits, and depression cause loss of independence, disability, decreased functioning, and reduced quality of life; these persist into the long term. There are theoretical grounds to consider that, through neuroplasticity and other mechanisms, such impairments can be prevented or attenuated by the early introduction of a selective serotonin reuptake inhibitor such as fluoxetine.
