TLDR
Pup behavioral alterations, including trembling, difficulty in righting, and fearfulness were reversed by the serotonin synthesis inhibitor parachlorophenylalanine, and adults manifested a distinct behavioral syndrome, including enhanced aggression in males.Abstract:
Deficiency in monoamine oxidase A (MAOA), an enzyme that degrades serotonin and norepinephrine, has recently been shown to be associated with aggressive behavior in men of a Dutch family. A line of transgenic mice was isolated in which transgene integration caused a deletion in the gene encoding MAOA, providing an animal model of MAOA deficiency. In pup brains, serotonin concentrations were increased up to ninefold, and serotonin-like immunoreactivity was present in catecholaminergic neurons. In pup and adult brains, norepinephrine concentrations were increased up to twofold, and cytoarchitectural changes were observed in the somatosensory cortex. Pup behavioral alterations, including trembling, difficulty in righting, and fearfulness were reversed by the serotonin synthesis inhibitor parachlorophenylalanine. Adults manifested a distinct behavioral syndrome, including enhanced aggression in males.read more

Developmental coordination disorder: is clumsy motor behavior caused by a lesion of the brain at early age?
TL;DR: Perinatal adversities play an evident etiological role in the development of complex MND, suggesting that it might be attributed to a lesion of the brain at early age, and in line with this idea is the finding thatcomplex MND shows a strong correlation with attention and learning problems.

TL;DR: The role of COMT in dopamine elimination is still minimal in conditions when DAT is inhibited, and attenuation of hyperlocomotion was observed after cocaine treatment in genetic background COMT-deficient male mice.

TL;DR: In this paper, the relationship between stress-induced MAO A and the transcription factor Kruppel-like factor 11 (KLF11), also called TIEG2, was elucidated.

Reactive oxygen species-responsive drug delivery systems for the treatment of neurodegenerative diseases.
TL;DR: This review article discusses the biology of ROS in both healthy and diseased nervous systems and recent developments in ROS- responsive, drug delivery system design to assist efforts to make better decisions about designing ROS-responsive, neural drug delivery systems, including the selection of ROS- responsiveness functional groups.
Journal ArticleDOI
Cellular expression of mRNAs encoding monoamine oxidases A and B in the rat central nervous system
TL;DR: In situ hybridization with 35S‐labelled oligonucleotide probes reveals further the potential of various cell populations to synthesize the isoenzymes, and homologous and heterologous patterns of expression as well as coexpression of MAO mRNAs are described.

Behavioral despair in mice: a primary screening test for antidepressants
Porsolt Rd,Bertin A,Jalfre M +2 more
TL;DR: The mouse procedure is more rapid and less costly than that with rats and is thus more suitable for the primary screening of antidepressant drugs, suggesting that the procedure is selectively sensitive to antidepressant treatments.

Functional role of type I and type II interferons in antiviral defense.

TL;DR: Comparison of mice lacking either type I or type II IFN receptors showed that, at least in response to some viruses, both IFN systems are essential for antiviral defense and are functionally nonredundant.

TL;DR: The author describes how his methods of investigation with celloidin embedded material prepared with the Golgi method and Nissl staining revealed for the first time the “barrel fields” of the mouse cerebral cortex that are activated by stimulation of the facial vibrissae (whiskers).

Abnormal behavior associated with a point mutation in the structural gene for monoamine oxidase A
TL;DR: Analytical results indicate that isolated complete MAOA deficiency in this family is associated with a recognizable behavioral phenotype that includes disturbed regulation of impulsive aggression.
