Gastrulation01:56

Gastrulation

58.5K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Enteric Nervous System: Regulation of GI Motor Activity

759
The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs.
During periods of fasting, the ENS initiates the migrating myoelectric complex, a...

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.
