MAIN OUTCOME MEASURE(S): Microscopic evaluation to assess the presence and localization of IL-10 throughout the menstrual cycle in both eutopic endometrial and adenomyotic tissues of women with adenomyosis and compare it with IL-10 expression in the normal endometrium. | |||||||||||||||
| |||||||||||||||
|
Dendritic cells isolated from MHV68 infected mice express IL-10 transcripts, and dendritic cells infected ex vivo secrete IL-10 only when concurrently stimulated with LPS [36]. | |||||||||||||||
| |||||||||||||||
|
Cells transduced with pBluescriptIISK were stimulated with 100 ng/mL of LPS following nucleofection as indicated. 48 hours post-nucleofection, supernatants were harvested and secreted IL-10 measured by ELISA (BD Biosciences).

|
In primary murine B cells, M2-driven proliferation was dependent on the B cell's ability to secrete IL-10 and respond to IL-10 signaling. | |||||||||||||||
| |||||||||||||||
|
It has been shown that ex vivo stimulation of MHV68 latently infected splenocytes with MHV68-infected antigen presenting cells resulted in IL-10 secretion peaking at the onset of splenic latency, and B cells were shown to be responsible for a significant portion of the IL-10 secreted [47]. | |||||||||||||||
| |||||||||||||||
|
M2 protein expression leads to secretion of IL-10 | |||||||||||||||
| |||||||||||||||
|
Untreated A20 cells secrete significant levels of IL-10, which were only modestly enhanced by LPS treatment (Figure 4F). | |||||||||||||||
| |||||||||||||||
|
These results provide strong evidence that M2 induction of IL-10 secretion, either from latently infected B cells or some other latency reservoir (e.g., infected macrophages or dendritic cells), contributes significantly to the serum levels of IL-10 observed during MHV68 infection following either intranasal or intraperitoneal virus inoculation.

| |||||||||||||||
|
Finally, to further assess the ability of M2 expression to up-regulate IL-10 secretion from B cells, we transfected the murine A20 B cell line with either a control expression vector (pIRES-EGFP) or an M2 expression vector (pM2-IEGFP) and assessed IL-10 secretion by ELISA (Figure 4F). | |||||||||||||||

It has been shown that ex vivo stimulation of MHV68 latently infected splenocytes with MHV68-infected antigen presenting cells resulted in IL-10 secretion peaking at the onset of splenic latency, and B cells were shown to be responsible for a significant portion of the IL-10 secreted [47]. | |||||||||||||||
| |||||||||||||||
|
Thus, we hypothesize that during M2-mediated reactivation there is concurrent IL-10 secretion, locally dampening the ability of the MHV68-specific CD8+ T cells to clear the infected cells, leading to enhanced establishment and reactivation from latency. | |||||||||||||||
| |||||||||||||||
|
These data demonstrate that M2 expression in primary murine B cells leads to enhanced secretion of several cytokines, most notably IL-10. | |||||||||||||||
| |||||||||||||||
|
Finally, to further assess the ability of M2 expression to up-regulate IL-10 secretion from B cells, we transfected the murine A20 B cell line with either a control expression vector (pIRES-EGFP) or an M2 expression vector (pM2-IEGFP) and assessed IL-10 secretion by ELISA (Figure 4F). | |||||||||||||||
| |||||||||||||||
|
In addition, transfection of the control expression vector had no impact of the levels of IL-10 secreted by A20 cells (Figure 4F). | |||||||||||||||
| |||||||||||||||
|
Interestingly, these investigators showed that M2 is transcribed by infected dendritic cells, although they did not demonstrate that IL-10 secretion was mediated by M2 [36]. | |||||||||||||||
| |||||||||||||||
|
VMD2-IL10 transgenic mice expressed high levels of secreted IL-10 in the retina, and were prone to develop CNV following laser-injury [3]. | |||||||||||||||
| |||||||||||||||
|
This is in agreement with our findings, as one can expect that released IL-10 in wildtype mice is inactivated by MMP-8. | |||||||||||||||
| |||||||||||||||
|
SYBR Green detection (Power SYBR® Green PCR Master Mix, Applied Biosystems, Warrington, UK), was used for Il1rn, Il1b, Il10, and Tnf. | |||||||||||||||
| |||||||||||||||
|
This indicates that intact peritoneal macrophages of SWISS mice are important for limiting PMN accumulation, perhaps mainly through the release of IL-10, but are not critical for the induction of anti-inflammatory effects of morphine during the early stages of peritonitis. | |||||||||||||||
| |||||||||||||||
|
mice, albeit at lower levels (Figure 8 B), suggesting that cells other than CD4+ T cells (such as macrophages) play a certain but subdominant role in secreting IL-10 during WNV infection in vivo. | |||||||||||||||
