mortality/aging
• in L. monocytogenes-infected mice
|
immune system
N |
• mice exhibit normal serum cytokine production
|
• by 8 weeks of age
|
• bone marrow cells exhibit increased granulocyte/macrophage colony formation compared with wild-type cells
|
• enlarged lysosomes containing undigested materials
|
• at 3 weeks of age, mice exhibit increased macrophage in the spleen compared with wild-type mice
• mice exhibit macrophage infiltration in multiple organs (including spleen, liver, pancreas and intestine) that worsens with age unlike in wild-type mice
• however, treatment with anti-macrophage colony-stimulating factor antibodies reduces splenic macrophage numbers
|
• macrophage proliferation and apoptosis are increased compared to in wild-type mice
• bone marrow-derived macrophage exhibit delayed degradation of apoptotic thymocytes and bacterial killing compared with wild-type cells
• bone marrow-derived macrophage challenged with exogenous apoptotic thymocytes exhibit an accumulation of adenosine in whole-cell extracts and purified lysosomal fraction
• however, bone marrow-derived macrophage exhibit normal phagocytosis and phagosome-lysosome fusion
|
• mice exhibit an increase in the absolute number of apoptotic macrophage compared with wild-type mice
|
• by 8 weeks of age
|
• L. monocytogenes-infected mice exhibit increased bacterial load and lethality compared with wild-type mice
|
• in L. monocytogenes-infected mice
|
hematopoietic system
• by 8 weeks of age
|
• bone marrow cells exhibit increased granulocyte/macrophage colony formation compared with wild-type cells
|
• extramedullary myelopoiesis without an acute inflammatory response due to defects in hematopoietic cells
|
• enlarged lysosomes containing undigested materials
|
• at 3 weeks of age, mice exhibit increased macrophage in the spleen compared with wild-type mice
• mice exhibit macrophage infiltration in multiple organs (including spleen, liver, pancreas and intestine) that worsens with age unlike in wild-type mice
• however, treatment with anti-macrophage colony-stimulating factor antibodies reduces splenic macrophage numbers
|

|
cellular
• mice exhibit an increase in the absolute number of apoptotic macrophage compared with wild-type mice
|
• accumulation of adenosine in whole-cell extracts and purified lysosomes derived from splenic macrophage indicate impaired lysosomal nucleoside export
|
neoplasm
• in moribund mice
• however, treatment with anti-macrophage colony-stimulating factor antibodies partially rescues histocytic phenotype
