immune system
abnormal thymus morphology ( J:141379 )
• GFP expressing cells are less complex in shape compared to GFP expressing cells in heterozygous mice
• GFP expressing cells tend to be localized uniformly within each medulla or enriched in the medulla center rather than enriched in the cortico-medullary junction as in heterozygous mice
absent Hassall's corpuscle ( J:141379 )
• Hassall's corpuscle-like structures are absent
abnormal thymus physiology ( J:141379 )
• the numbers of medullary thymic epithelial cells expressing involucrin are significantly reduced, especially at 4 and 8 weeks of age
autoimmune response ( J:141379 )
• display autoimmune pathology with onset at 4 to 6 weeks of age
