Delayed Outgrowth in Response to the BDNF and Altered Synaptic Proteins in Neurons From SHR Rats.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity symptoms. Neuroimaging studies have revealed a delayed cortical and subcortical development pattern in children diagnosed with ADHD. This study followed up on the development in vitro of frontal cortical neurons from Spontaneously hypertensive rats (SHR), an ADHD rat model, and Wistar-Kyoto rats (WKY), control strain, over their time in culture, and in response to BDNF treatment at two different days in vitro (DIV).

Sex differences in maternal odor preferences and brain levels of GAP-43 and sonic hedgehog proteins in infant SHR and Wistar Kyoto rats.

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that presents sex differences in the severity and presentation of symptoms, whose neurobiological basis is still unknown. Both Growth-associated Protein 43 (GAP-43) and Sonic hedgehog (Shh) are considered essential proteins for the appropriate brain development, but their participation in ADHD neurobiology have not been investigated yet. In this study, we hypothesized that alterations in these proteins could be related to behavioral traits to ADHD phenotype.

The Age of Brain Organoids: Tailoring Cell Identity and Functionality for Normal Brain Development and Disease Modeling.

Over the past years, brain development has been investigated in rodent models, which were particularly relevant to establish the role of specific genes in this process. However, the cytoarchitectonic features, which determine neuronal network formation complexity, are unique to humans. This implies that the developmental program of the human brain and neurological disorders can only partly be reproduced in rodents.

Neuromodulation and neuroprotective effects of chlorogenic acids in excitatory synapses of mouse hippocampal slices.

The increased healthspan afforded by coffee intake provides novel opportunities to identify new therapeutic strategies. Caffeine has been proposed to afford benefits through adenosine A receptors, which can control synaptic dysfunction underlying some brain disease. However, decaffeinated coffee and other main components of coffee such as chlorogenic acids, also attenuate brain dysfunction, although it is unknown if they control synaptic function.
