And Now for some news ….
Neurotransmitters and the Gut Brain Axis
A study published in the Journal of Cellular Physiology, looked at the role of Neurotransmitters and the Gut Brain Axis.
Neurotransmitters, including catecholamines and serotonin, play a crucial role in maintaining homeostasis in the human body. Studies on these neurotransmitters mainly revolved around their role in the “fight or flight” response, transmitting signals across a chemical synapse and modulating blood flow throughout the body. However, recent research has demonstrated that neurotransmitters can play a significant role in the gastrointestinal (GI) physiology.
Norepinephrine (NE), epinephrine (E), dopamine (DA), and serotonin have recently been a topic of interest because of their roles in the gut physiology and their potential roles in GI and central nervous system pathophysiology. These neurotransmitters are able to regulate and control not only blood flow, but also affect gut motility, nutrient absorption, GI innate immune system, and the microbiome.
Furthermore, in pathological states, such as inflammatory bowel disease (IBD) and Parkinson’s disease, the levels of these neurotransmitters are dysregulated therefore causing a variety of GI symptoms.
Research in this field has shown that exogenous manipulation of catecholamine serum concentrations can help in decreasing symptomology and/or disease progression.
In this review article, the authors discuss the current state-of-the-art research and literature regarding the role of neurotransmitters in regulation of normal GI physiology, their impact on several disease processes, and novel work focused on the use of exogenous hormones and/or psychotropic medications to improve disease symptomology.

Physical exercise as an epigenetic modulator of brain plasticity and cognition
A large amount of evidence has demonstrated the power of exercise to support cognitive function, the effects of which can last for considerable time.
An emerging line of scientific evidence indicates that the effects of exercise are longer lasting than previously thought up to the point to affect future generations. The action of exercise on epigenetic regulation of gene expression seem central to building an “epigenetic memory” to influence long-term brain function and behavior.
In a recent review article, the authors discuss new developments in the epigenetic field connecting exercise with changes in cognitive function, including DNA methylation, histone modifications and microRNAs (miRNAs).
The understanding of how exercise promotes long-term cognitive effects is crucial for directing the power of exercise to reduce the burden of neurological and psychiatric disorders.
