immune system

• diptheria toxin (DT) administration induced depletion of plasmacytoid dendritic cells (pDC)
• depletion efficiency in blood, spleen, liver and lymph nodes is approximately 90% 24-48 hrs after DT treatment
|
|
• decreased frequencies and numbers of antigen-specific CD8+ T cells in DT-treated mice infected with recombinant VSV expressing ovalbumin (VSV-OVA)

small spleen
(
J:166504
)
|
• spleens from VSV-OVA infected DT-treated mice are smaller and have fewer cells than controls
|
|
• spleens from VSV-OVA infected DT-treated mice are smaller and have fewer cells than controls
|
|
• 2.5 fold increase in number of IFNg-producing NK cells in DT-treated (pDC-depleted) mice as compared to untreated control
• increase in frequency of NK1.1+ and Ly49H+ NK cells in DT-treated (pDC-depleted) mice during later phase of murine cytomegalovirus (MCMV) infection as compared to untreated control
|
|
• Ly49H+ NK cells from DT-treated (pDC-depleted) mice are less efficient at killing target cells
|
|
• less specific lysis is observed in antigen-specific CD8+ T cells found in VSV-OVA infected DT-treated mice
|
|
• increased frequencies of IFNg-producing NKT cells found in spleens and livers of DT-treated (pDC-depleted) mice
|
|
• reduction in serum CCL4 observed in VSV-OVA infected DT-treated mice 24 hours post infection (p.i.)
|
|
• DT-treated (pDC-depleted) mice exhibit decreased serum IFNa secretion 36 hours post MCMV infection although no differences are observed at 48 hours p.i.
• DT-treated (pDC-depleted) mice exhibit decreased serum IFNa secretion 6 hours post infection with recombinant VSV expressing ovalbumin (VSV-OVA) but not at 12 or 24 hours p.i.
|
|
• DT-treated (pDC-depleted) mice exhibit a 3-4x increase in serum IFNg secretion as compared to untreated controls 48 hours after MCMV at 104 pfu, but not at 105 pfu
|
|
• increase in IL12 producing CD11chi cells in DT-treated mice as compared to control
• increase in serum IL12 in DT-treated mice
|
|
• intraperitoneal infection with murine cytomegalovirus (MCMV) in DT-treated (pDC-depleted) mice results in significantly higher viral titers in spleen and liver 3 days post infection (3 p.i.) as compared to untreated controls
• salivary glands from MCMV infected DT-treated mice at 8 p.i. have elevated viral loads at 104 pfu, but not at 105 pfu as compared to untreated controls
• infection with recombinant VSV results in higher viral titers in spleen at 6 hours p.i. as compared to untreated controls, but VSV is undetectable in periphery after 24 hours
