Macrophages showed a rapid inflammatory response in which the expression of interleukin-1beta (IL-1beta), major histocompatibility complex class II (MHC II), inducible cyclo-oxygenase (Cox-2), and inducible nitric oxide synthase (iNOS) was enhanced, but tumour necrosis factor-alpha (TNF-alpha) expression was greatly reduced initially and then increased.
|

12047757
|
After 5 days, except for TNF-alpha and MHC II, expression returned to levels approaching those of uninfected macrophages.
|

|
We found that msa reduced the expression of IL-1beta, Cox-2, and MHC II but stimulated TNF-alpha while hly, rsh and grp stimulated MHC II but down-regulated TNF-alpha.
|

Splenic PGE2-M Ø from Balb/c mice, given 0.01 or 1 mg heat-killed (HK) Mycobacterium bovis bacillus Calmette-Guerin (BCG) intraperitoneally (i.p.), were characterized by the ex vivo release of PGE2 (>10 ng/10(6) cells), cytokine production, and expression of PGG/H synthase (PGHS)-1, PGHS-2, cytosolic PGE synthase (PGES), and microsomal PGES-1.
|
37 |
16204627
|
At Day 14 after the treatment, mice treated with 1 mg, but not 0.01 mg, BCG had increased levels of PGHS-2+ PGE2-MØ, total serum immunoglobulin E (IgE), and serum IgG1 antibodies (Th2 responses) against heat shock protein 65 and purified protein derivative.

Contrasting effects of cyclooxygenase-1 (COX-1) and COX-2 deficiency on the host response to influenza A viral infection.
|
53 |
16272346
|
The cyclooxygenase (COX) pathway is important in modulating immune responses and is also a major target of nonsteroidal anti-inflammatory drugs (NSAIDs) and the newer COX-2 inhibitors.
|
54 |
16272346
|
The purpose of the present study was to examine the effect of deficiency of COX-1 or COX-2 on the host response to influenza.
|
55 |
16272346
|
We used an influenza A viral infection model in wild type (WT), COX-1-/-, and COX-2-/- mice.
|
56 |
16272346
|
Infection induced less severe illness in COX-2-/- mice in comparison to WT and COX-1-/- mice as evidenced by body weight and body temperature changes.
|
57 |
16272346
|
COX-1-/- mice had enhanced inflammation and earlier appearance of proinflammatory cytokines in the BAL fluid, whereas the inflammatory and cytokine responses were blunted in COX-2-/- mice.
|
58 |
16272346
|
However, lung viral titers were markedly elevated in COX-2-/- mice relative to WT and COX-1-/- mice on day 4 of infection.
|
59 |
16272346
|
Levels of PGE2 were reduced in COX-1-/- airways whereas cysteinyl leukotrienes were elevated in COX-2-/- airways following infection.
|
60 |
16272346
|
Thus, deficiency of COX-1 and COX-2 leads to contrasting effects in the host response to influenza infection, and these differences are associated with altered production of prostaglandins and leukotrienes following infection.
|

The cyclooxygenase (COX) pathway is important in modulating immune responses and is also a major target of nonsteroidal anti-inflammatory drugs (NSAIDs) and the newer COX-2 inhibitors.

124 |
16272346

The purpose of the present study was to examine the effect of deficiency of COX-1 or COX-2 on the host response to influenza.

125 |
16272346
|
We used an influenza A viral infection model in wild type (WT), COX-1-/-, and COX-2-/- mice.
|
126 |
16272346
|
Infection induced less severe illness in COX-2-/- mice in comparison to WT and COX-1-/- mice as evidenced by body weight and body temperature changes.
|
127 |
16272346
|
COX-1-/- mice had enhanced inflammation and earlier appearance of proinflammatory cytokines in the BAL fluid, whereas the inflammatory and cytokine responses were blunted in COX-2-/- mice.
|
128 |
16272346
|
However, lung viral titers were markedly elevated in COX-2-/- mice relative to WT and COX-1-/- mice on day 4 of infection.
|
129 |
16272346
|
Levels of PGE2 were reduced in COX-1-/- airways whereas cysteinyl leukotrienes were elevated in COX-2-/- airways following infection.
|
130 |
16272346
|
Thus, deficiency of COX-1 and COX-2 leads to contrasting effects in the host response to influenza infection, and these differences are associated with altered production of prostaglandins and leukotrienes following infection.

Tumor-derived cyclooxygenase-2 (COX-2) and its product, prostaglandin E2, exert strong immunoinhibitory effects that block dendritic cell function and CD4+ and CD8+ T-cell proliferation and function.
|
153 |
16397045
|
Increased immunocyte trafficking was likely mediated by the generation of a Th1-type tumor microenvironment because COX-2 inhibition increased expression levels of mRNA for IFN-gamma, interleukin-12, IP-10, and MIG while lowering the expression of vascular endothelial growth factor within tumors.

Previous studies have shown that prostaglandin E(2) (PGE(2)) release by splenic F4/80(+) cyclooxygenase (COX)-2(+) macrophages (MØ) isolated from mice, treated with mycobacterial components, plays a major role in the regulation of immune responses.
|
157 |
16822852
|
However, splenic MØ, isolated from untreated mice and treated in vitro with lipopolysaccharide and interferon-gamma, express COX-1 and COX-2 within 1 day but release only minimal amounts of PGE(2) following elicitation with calcium ionophore A23187.
|
158 |
16822852
|
In sharp contrast, 14 days after HK-BCG treatment, PGE(2) release by COX-2(+) splenic MØ increased as much as sevenfold, and a greater increase was seen in IL-10(-/-) cells than in WT cells.

|
Specific inhibitors of mitogen-activated protein kinases (MAPKs), SB203580, PD98059, and SP600125, significantly abolished HO-1 expression.
|
258 |
23536693
|
In addition, MALP-2 also induced NF-E2-related factor 2 (Nrf2) translocation, and the silencing of Nrf2 expression in THP-1 cells decreased the levels of MALP-2-mediated HO-1 expression.
|
259 |
23536693
|
Furthermore, COX-2 protein expression levels were upregulated in THP-1 cells in response to MALP-2, and transfection with small interfering RNAs of HO-1 significantly increased COX-2 accumulation.
|
260 |
23536693
|
These results demonstrate that MALP-2 induces HO-1 expression via MAPKs and Nrf2 pathways and, furthermore, that MALP-2-induced COX-2 expression was modulated by HO-1 in THP-1 cells.

24343645
|
In this study, we show that cPLA2, p38 mitogen-activated protein kinase (MAPK), and Janus kinase 3 (JAK3) signaling are necessary for F. tularensis-induced PGE2 production.

In addition, JAK3 regulates cPLA2 phosphorylation independent of transcription.
|
273 |
24343645
|
Moreover, p38 MAPK activity is required for F. tularensis-induced COX-2 protein synthesis, but not for the phosphorylation of cPLA2.

The production of eicosanoids from Arachidonic Acid (AA) can be hampered due to suppression of the enzyme phospholipase A2 by IL-4, an essential cytokine required for the differentiation of DCs.
|
302 |
25369453
|
Thus addition of AA to the culture media is skewing the DCs towards the secretion of more IL-12 and less of IL-10 along with the restoration of eicosanoids levels in a COX-2 mediated pathway thereby enhancing the functionality of these cells to be used as a potent cellular vaccine.
