Impaired Skeletal Development by Disruption of Presenilin-1 in Pigs and Generation of Novel Pig Models for Alzheimer's Disease
Uh et al., Journal of Alzheimer's Disease. 2024.
https://pubmed.ncbi.nlm.nih.gov/39177593/
This study explored the effects of presenilin 1 (PSEN1) disruption on vertebral malformations in male and female PSEN1 mutant pigs. Researchers observed significant skeletal impairments and early deaths in pigs with a PSEN1 null mutation, mirroring phenotypes seen in mouse models of Alzheimer’s disease (AD). This porcine model provides valuable insights into pathological hallmarks of PSEN1 mutations in AD, offering a robust platform of therapeutic exploration. The findings establish pigs as an essential translational model for AD, enabling advanced studies on pathophysiology and treatment development for human skeletal and neurological conditions.

Interneuron Origins in the Embryonic Porcine Medial Ganglionic Eminence
Casalia et al., Journal of Neuroscience. 2021.
https://pubmed.ncbi.nlm.nih.gov/33637558/
The authors report that transcription factor expression patterns in porcine embryonic subpallium are similar to rodents. Their findings reveal that porcine embryonic MGE progenitors could serve as a valuable source for interneuron-based xenotransplantation therapies. They demonstrate that porcine medial ganglionic eminence exhibits a distinct transcriptional and interneuron-specific antibody profile, in vitro migratory capacity, and are amenable to xenotransplantation. This is the first comprehensive examination of embryonic interneuron origins in the pig; because a rich neurodevelopmental literature on embryonic mouse medial ganglionic eminence exists (with some additional characterizations in monkeys and humans), their work allows direct neurodevelopmental comparisons with this literature. Supported by ORIP (U42OD011140) and NINDS.
