Nausea is an uncomfortable sensation that accompanies many therapeutics, especially diabetes treatments involving glucagon-like peptide-1 receptor (GLP1R) agonists. Recent studies in mice have revealed that GLP1R-expressing neurons in the area postrema play critical roles in nausea. Here, we characterized a ligand-conjugated saporin that can efficiently ablate GLP1R cells from humans, mice, and the Suncus murinus, a small animal model capable of emesis. This new tool provides a strategy to manipulate specific neural pathways in the area postrema in the Suncus murinus and may help elucidate roles of area postrema GLP1R neurons in emesis during therapeutics involving GLP1R agonists.

Introduction: The area postrema, located on the floor of the fourth ventricle, regulates vomiting, fluid balance, osmoregulation, and immunomodulation. First documented in 1896, it has been a subject of scientific interest ever since. Area postrema syndrome (APS) is characterised by intractable nausea, vomiting, or hiccups, typically associated with neuromyelitis optica spectrum disorder (NMOSD).

Our internal sensory systems encode various gut-related sensations, such as hunger, feelings of fullness, and nausea. These internal feelings influence our eating behaviors and play a vital role in regulating energy balance. Among them, the neurological basis for nausea has been the least well characterized, which has hindered comprehension of the connection between these sensations.

Among contributors to diffusible signaling are portal systems which join two capillary beds through connecting veins. Portal systems allow diffusible signals to be transported in high concentrations directly from one capillary bed to the other without dilution in the systemic circulation. Two portal systems have been identified in the brain.

An 80-year-old man with aquaporin-4-antibody-positive neuromyelitis optica spectrum disorder presented with a 2-week history of cough and hiccups, followed by progressive bilateral lower limb weakness, a bandlike burning sensation in the upper body, and urinary retention. Magnetic resonance imaging showed area postrema and thoracic central medullary lesions. Thorax computed tomography showed bilateral upper lung lobe consolidations.

Introduction: Although neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody disease (MOGAD) are rare diseases, they pose a significant burden on both society and the healthcare system. This study aims to discuss the demographics and patient characteristics of these diseases in a single center in the United Arab Emirates (UAE).

Methods: This is a retrospective, descriptive study that included patients with either NMOSD or MOGAD treated at Rashid Hospital, UAE during the period between January 2019 and January 2024.
