Going with the Flow: Sensorimotor Integration Along the Zebrafish GI Tract

Area of Science:

• Neuroscience
• Developmental Biology
• Gastroenterology

Background:

• Sensorimotor integration in the gastrointestinal (GI) tract is vital for gut function but poorly understood in neurodevelopmental disorders (NDDs).
• Autism spectrum disorder (ASD) frequently involves GI symptoms, suggesting altered sensorimotor processing along the GI tract.

Purpose of the Study:

• To investigate the functional circuits of digestion in vivo using zebrafish models.
• To elucidate mechanisms underlying GI-related symptoms in ASD by examining sensorimotor integration.
• To explore potential therapeutic strategies for mitigating GI distress in NDDs.

Main Methods:

• Utilizing zebrafish for their genetic tractability and molecularly defined models.
• Employing optogenetics and calcium imaging due to zebrafish's developmental optical transparency.
• Examining key digestive reflex arcs: swallowing, nutrient-sensing, absorption, peristalsis, and evacuation.

Main Results:

• (Study is proposed, results not yet available in abstract)

Conclusions:

• Understanding zebrafish GI sensorimotor circuits can provide insights into ASD and other NDDs.
• Zebrafish offer a powerful model for studying conserved digestive processes and developing NDD therapeutics.
• This research aims to bridge the gap in knowledge regarding NDDs and GI dysfunction.
