The infected mice displayed a significant up-regulation in the expression of chemokines (Cxcl1, Cxcl2 and Ccl2), numerous pro-inflammatory cytokines (Ifng, Il1b, Il6, and Il17f), as well as Il22 and a number of anti-microbial peptides (Defa1, Defa28, Defb1, Slpi and Reg3g) at the site(s) of infection.

|
However, CD4 T cells of the untreated and C. difficile-infected mice expressed similar levels of CD69 and CD25.

|
Neither tissue had up-regulated levels of Tbx21, Gata3 or Rorc.

|
They also displayed significantly higher phosphorylation of AKT and signal transducer and activator of transcription 3 (STAT3), an indication of pro-survival signalling.

|
These data underscore the local, innate, pro-inflammatory nature of the response to C. difficile and highlight eIF2α phosphorylation and the interleukin-22-pSTAT3-RegIIIγ axis as two of the pathways that could be used to contain and counteract the damage inflicted on the intestinal epithelium.

We previously reported that foetuses congenitally infected with Trypanosoma cruzi, the agent of Chagas disease, mount an adult-like parasite-specific CD8(+) T-cell response, producing IFN-g, and present an altered NK cell phenotype, possibly reflecting a post-activation state supported by the ability of the parasite to trigger IFN-g synthesis by NK cells in vitro.

|
Twenty-four hours co-culture of cord blood mononuclear cells with T. cruzi trypomastigotes and IL-15 induced high accumulation of IFN-g transcripts and IFN-g release.

|
TNF-a, but not IL-10, was also produced.
|
| 9 |

|
This was associated with up-regulation of CD69 and CD54, and down-regulation of CD62L on NK cells.
|

|
The CD56(bright) NK cell subset was the major IFN-g responding subset (up to 70% IFN-g-positive cells), while CD56(dim) NK cells produced IFN-g to a lesser extent.

|
This work highlights the ability of T. cruzi to trigger a robust IFN-g response by IL-15-sensitized human neonatal NK cells and the important role of monocytes in it, which might perhaps partially compensate for the neonatal defects of DCs.
|
| 12 |
23819002
|
It suggests that monocyte- and IL-12- dependent IFN-g release by NK cells is a potentially important innate immune response pathway allowing T. cruzi to favour a type 1 immune response in neonates.

|
Interestingly, submicromolar doses of iPA stimulate resting human NK cells and synergize with IL-2 to induce a robust activation ex vivo with significant secretion of CCL5 and CCL3 and a large increase in TNF-α and IFN-γ production when compared with IL-2 single cytokine treatment.
|

|
Moreover, iPA promotes NK cell proliferation and up-regulates the expression of specific NK cell-activating receptors, as well as CD69 and CD107a expression.

|
Statistical analysis indicated 6 genes, namely IFNG, IL2, XCL1, CD69, CSF2 and CXCL10, as significantly upregulated by PTx which was also demonstrated at the protein level for genes encoding secreted proteins.
