reproductive system
• normal phenotype at birth
• pathological changes develop with age in testes
|
• decreased fertility due to pathological changes that develop in testes with age
|
adipose tissue
• aging mice develop lymphocytic infiltrates in adipose tissue
|
immune system
• aging mice develop lymphocytic infiltrates in adipose tissue
|
• elevated antinuclear antibodies in 6-8 month old mice relative to age matched controls
|
• aging mice develop lymphocytic infiltrates in the stroma
|
• aging mice develop lymphocytic infiltrates in the stroma
|
• aging mice develop lymphocytic infiltrates in the stroma
• early stage changes include mild and focal lymphocyte infiltrations with occasional plasma cells, around centrilobular thin walled vessels
• middle phase changes include thick and continuous infiltrates expanding around vessels and bronchioli and expanding into inter-alveolar compartment
• late stage changes include substantial accumulation of immunoglobulin producing plasma cells with Russell bodies, filling of alveoli with macrophage, necrotizing pseudogranulomatous nodules
• advanced lesions in 15% of mice by 6-12 months and in 48% by 12-24 months
|
• lymphocytic interstitial pneumonia is part of late stage changes
|
• aging mice develop lymphocytic infiltrates in the stroma
