FACS analysis of T cells from MLN and lung tissue demonstrated that T cells expressing any of the activation markers tested (LFA-1, CD25, CD44, CD45RB, CD49d, CD62L) always expressed high levels of CD44 and LFA-1.

These double-high T cells produced >99% of all anti-CD3 mAb-induced IL-4 and IFN-gamma.
|

9233612
|
Despite their similar phenotype, purified double-high lung parenchyma T cells produced markedly higher levels of IL-2, IL-4, and IFN-gamma, and contained a higher frequency of cytokine producers than their MLN counterparts.
|

9233612
|
Activation of the extracellular signal-regulated kinase (ERK)-2 in response to TCR cross-linking was detected in double-high T cells from lung tissue but not MLN.

|
The requirement for ERK signaling for maximal IFN-gamma synthesis could nevertheless be demonstrated in both populations by blockade with the inhibitor PD98509.

Upon activation in vivo, they more efficiently induce phosphorylation of-LAT (linker for activation of T cells), ERK (extracellular signal-regulated kinase), JNK (c-Jun N-terminal kinase), and p38.

Cutting edge: different Toll-like receptor agonists instruct dendritic cells to induce distinct Th responses via differential modulation of extracellular signal-regulated kinase-mitogen-activated protein kinase and c-Fos.
|

14607893
|
Thus, Escherichia coli LPS and flagellin, which trigger TLR4 and TLR5, respectively, instruct DCs to stimulate Th1 responses via IL-12p70 production, which depends on the phosphorylation of p38 and c-Jun N-terminal kinase 1/2.
|
9 |
14607893
|
In contrast, the TLR2 agonist, Pam3cys, and the Th2 stimulus, schistosome egg Ags: 1) barely induce IL-12p70; 2) stimulate sustained duration and magnitude of extracellular signal-regulated kinase 1/2 phosphorylation, which results in stabilization of the transcription factor c-Fos, a suppressor of IL-12; and 3) yield a Th2 bias.

CD4-directed peptide vaccination augments an antitumor response, but efficacy is limited by the number of CD8+ T cell precursors.
|
20 |
15034034
|
We investigated the effects of CD4-directed peptide vaccination on the ability of CD8(+) T cells to mount protective antitumor responses in the DUC18/CMS5 tumor model system.
|
21 |
15034034
|
Immunization with this peptide (tumor-derived extracellular signal-regulated kinase-II (tERK-II)) induced Ag-specific CD4(+) T cell effector function, but did not directly prime CD8(+) T cells.
|
22 |
15034034
|
Heightened CD4(+) Th cell function in response to tERK II vaccination allowed a 12-fold reduction in the number of adoptively transferred CD8(+) DUC18 T cells needed to protect recipients against tumor challenge as compared with previous studies using unimmunized mice.
|
23 |
15034034
|
These findings illustrate that CD4-directed peptide vaccination augments antitumor immunity, but that the number of tumor-specific precursor CD8(+) T cells will ultimately dictate the success of immunotherapy.

A Toll-like receptor 2 ligand stimulates Th2 responses in vivo, via induction of extracellular signal-regulated kinase mitogen-activated protein kinase and c-Fos in dendritic cells.
|
25 |
15067049
|
Thus, Escherichia coli LPS (TLR-4 stimulus), activates DCs to produce abundant IL-12(p70), but little IL-10, and stimulates Th1 and Tc1 responses.
|
26 |
15067049
|
In contrast, Pam-3-cys (TLR-2 stimulus) elicits less IL-12(p70), but abundant IL-10, and favors Th2 and T cytotoxic 2 (Tc2) responses.
|
27 |
15067049
|
Thus, Pam-3-cys induces enhanced extracellular signal-regulated kinase signaling, compared with LPS, resulting in suppressed IL-12(p70) and enhanced IL-10 production, as well as enhanced induction of the transcription factor, c-Fos.
|
28 |
15067049
|
Interestingly, DCs from c-fos(-/-) mice produce more IL-12(p70), but less IL-10, compared with control DCs.

TgHSP70 induced the maturation of human monocyte-derived dendritic cells as determined by increased levels of surface markers, namely, CD40, CD80, CD86, and HLA-DR.
|
35 |
15336548
|
TgHSP70 also stimulated extracellular signal-regulated kinase and p38 kinase pathways in DCs, and TgHSP70-induced IL-12 production was inhibited by SB203580 but not by PD98059, thus indicating the role of p38 kinase in the maturation of DCs by TgHSP70.

In this study, we provide evidence that the signaling events induced by M. bovis BCG in these cells included phosphorylation of extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK).
|
41 |
15894298
|
Our data also demonstrate that M. bovis BCG-induced CXC chemokine ligand (CXCL)8 release in epithelial cells was reduced by a mitogen-activated protein/ERK kinase (MEK) inhibitor (PD98059), but not by a p38 MAPK (SB203580) inhibitor.
|
42 |

|
Phosphorylation of the extracellular signal-regulated kinase and the stress-activated kinase p38 was significantly decreased.
|

Herein, we show that SAG induces extracellular signal-regulated kinase 1 (ERK-1) and ERK-2 phosphorylation through phosphoinositide 3-kinase (PI3K), protein kinase C, and Ras activation and p38 mitogen-activated protein kinase (MAPK) phosphorylation through PI3K and Akt activation.
|
44 |
16641451
|
ERK-1 and ERK-2 activation results in an increase in the production of reactive oxygen species (ROS) 3 to 6 h after SAG treatment, while p38 MAPK activation and subsequent tumor necrosis factor alpha release result in the production of nitric oxide (NO) 24 h after SAG treatment.

Ganglioside GM3 promotes carcinoma cell proliferation via urokinase plasminogen activator-induced extracellular signal-regulated kinase-independent p70S6 kinase signaling.
|
46 |
16826166
|
Overexpression of NeuAcalpha2-3Galbeta1-4Glcbeta1-Cer (GM3), a major ganglioside of cutaneous tumor cell membranes, inhibits ligand-dependent and ligand-independent activation of the epidermal growth factor (EGF) receptor in normal and neoplastic epithelial cells.
|
47 |
16826166
|
This leads to the suppression of Ras/extracellular signal-regulated kinase (ERK) activation and, in the presence of EGF or fibronectin, inhibits cell proliferation.
|
48 |
16826166
|
We report that in the presence of urokinase plasminogen activator (uPA), overexpression of GM3 paradoxically increases the proliferation of carcinoma cells by augmenting ERK-independent p70S6 kinase activation.
|
49 |
16826166
|
Functional blockade of uPA receptor (uPAR) or inhibition of p70S6 kinase, but not inhibition of Ras/ERK signaling, suppresses this GM3-induced stimulation of cell proliferation.
|
50 |
16826166
|
The ERK-independent activation of p70S6 kinase involves phosphorylation at threonine-389, threonine-421/serine-424, and serine-411 sites with intermediate phosphatidylinositol 3 kinase and protein kinase C-zeta activation.
|
51 |
16826166
|
These studies implicate gangliosides as enhancers of uPAR-related signaling and suggest that the response to GM3 depends on the local concentration of uPA.
|
52 |
16826166
|
Therapeutic modalities that target or supplement gangliosides may require concomitant treatment that suppresses EGFR or uPAR signaling, respectively, to control neoplastic cell proliferation.

Mechanism of adjuvant activity of cationic liposome: phosphorylation of a MAP kinase, ERK and induction of chemokines.
|
62 |
17521728
|
Microarray of mRNA analysis demonstrated that several chemokine genes are up-regulated by DOTAP liposome, including CCL2, CCL3 and CCL4, upon treatment of dendritic cells (DC) with DOTAP liposomes.
|
63 |
17521728
|
CCL2 induction was mediated through extracellular-signal-regulated kinase (ERK) pathway, demonstrated by specific inhibitors of ERK pathway and siRNA approaches.
|
64 |
17521728
|
Furthermore, DOTAP-induced CCL2 expression is negatively regulated by the p38 pathway.
|
65 |
17521728
|
Moreover, PI-3 kinase was shown to be involved in both activation of ERK and induction of CCL2 by DOTAP.
|
66 |
17521728
|
More importantly, inhibition of ERK pathway completely abolishes the CCL2 accumulation in the draining lymph nodes and attenuates anti-tumor activity of DOTAP/E7.

Thimerosal-induced apoptosis in human SCM1 gastric cancer cells: activation of p38 MAP kinase and caspase-3 pathways without involvement of [Ca2+]i elevation.
|
68 |
17698513
|
Although immunoblotting data revealed that thimerosal could activate the phosphorylation of extracellular signal-regulated kinase, c-Jun NH2-terminal protein kinase, and p38 mitogen-activated protein kinase (p38 MAPK), only SB203580 (a p38 MAPK inhibitor) partially prevented cells from apoptosis.
|
69 |
17698513
|
The results suggest that in SCM1 cells, thimerosal caused Ca2+-independent apoptosis via phosphorylating p38 MAPK resulting in caspase-3 activation.
|
70 |
18180378
|
Activation of extracellular signal-regulated kinase (ERK) increased TGF-beta expression while expression of a constitutively activated interferon regulatory factor-3 (IRF3) stimulated IL-10 secretion by DCs.
|
71 |
18180378
|
ERK and IRF3 suppressed the immune response and stimulated expansion of regulatory T cells.

Regulatory T cell-resistant CD8+ T cells induced by glucocorticoid-induced tumor necrosis factor receptor signaling.
|
73 |
18632650
|
We previously found that a Salmonella typhimurium vector engineered to secrete soluble tumor antigen induces CD4(+) T cells resistant to CD4(+)CD25(+) regulatory T cells (Treg) and that glucocorticoid-induced tumor necrosis factor receptor family-related gene (GITR) signal is involved in the development of this resistance.
|
74 |
18632650
|
In this study, we address the potential of incorporating GITR ligand (GITRL) as a way to augment the immunogenicity of cancer vaccines.
|
75 |
18632650
|
BALB/c mice were immunized by gene gun with plasmids encoding the mutated extracellular signal-regulated kinase 2 (mERK) with or without plasmids encoding mouse GITRL.
|
76 |
18632650
|
Coadministration with GITRL during primary and secondary immunization enhanced the induction of mERK-specific CD8(+) T cells.
|
77 |
18632650
|
Antibody depletion and minigene analysis suggested that GITRL directly activated CTL epitope-specific CD8(+) T cells independently of CD4(+) T cells.
|
78 |
18632650
|
Immunization with plasmids encoding a CTL epitope and GITRL resulted in strong tumor inhibition in a CD8(+) T cell-dependent manner.
|
79 |
18632650
|
Furthermore, CTL epitope-specific CD8(+) T cells induced by immunization with plasmids encoding CTL epitope coadministered with GITRL were refractory to suppression by CD4(+)CD25(+) Tregs compared with CD8(+) T cells induced without GITR signaling.

|
Using recombinant vaccinia virus (VV) and canarypox virus (ALVAC) expressing enhanced green fluorescent protein (EGFP) or multiple HIV-1 gene products, we studied the role of four cellular signaling pathways, the phosphoinositide-3-OH kinase (PI3K), extracellular signal-regulated kinase (ERK), p38 mitogen-activated protein kinase (p38 MAPK), and c-Jun N-terminal kinase (JNK), in poxvirus-mediated foreign gene expression in mammalian cells.
|
81 |
19428911
|
In nonpermissive infection (human monocytes), activation of PI3K, ERK, p38 MAPK, and JNK was observed in both VV and ALVAC and blocking PI3K, p38 MAKP, and JNK pathways with their specific inhibitors significantly reduced viral and vaccine antigen gene expression.

The objective of this study was to investigate the effects of glucose-based peritoneal dialysis (PD) fluids and icodextrin-based PD fluids on the expression of Toll-like receptor 2 (TLR2)/TLR4 and subsequent ligand-induced mitogen-activated protein kinase (MAPK) and NF-kappaB signaling and tumor necrosis factor alpha (TNF-alpha) and interleukin-1beta (IL-1beta) mRNA expression in human peritoneal mesothelial cells (HPMCs).
|
83 |
20200188
|
TLR2/TLR4 expression was determined by real-time PCR, Western blotting, and an immunofluorescence assay.
|
84 |
20200188
|
In addition, cells were pretreated with different PD solutions and then incubated with Pam3CSK4 or lipopolysaccharide (LPS), and the degrees of MAPK and NF-kappaB activation were reflected by detecting the phosphorylation levels of extracellular signal-regulated kinase 1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), p38, and p65, using a Western blot method.
|
85 |
20200188
|
TNF-alpha and IL-1beta mRNA expression was measured by real-time PCR.
|
86 |
20200188
|
Glucose-based peritoneal dialysis fluids suppressed the expression of TLR2 and TLR4 proteins in HPMCs.
|
87 |
20200188
|
Challenge of cells with either Pam3CSK4 or LPS resulted in impaired TNF-alpha and IL-1beta production.
|
88 |
20200188
|
Moreover, reduced TLR2 and TLR4 levels in glucose-based peritoneal dialysis solution-treated mesothelial cells were accompanied by reduced p42/44 (ERK1/2), JNK, p38 MAPK, and NF-kappaB p65 phosphorylation upon TLR ligand engagement.
|
89 |
20200188
|
No significant changes in MAPK and NF-kappaB signaling and TNF-alpha and IL-1beta mRNA expression were observed in icodextrin-based PD solution-treated mesothelial cells.
|
90 |
20200188
|
Glucose-based PD solution, but not icodextrin-based PD solution, downregulates expression of TLR2/TLR4 by human peritoneal mesothelial cells and triggers hyporesponsiveness to pathogen-associated molecular patterns.

|
Production of monocyte chemoattractant protein-1 (MCP-1/CCL2), macrophage inflammatory protein-1 (MIP-1/CCL3) and regulated on activation, normal T cell expressed and secreted (RANTES/CCL5), were determined in cell culture supernatants by ELISA or cytokine cytometric bead array.
|
92 |
20451253
|
Pharmacological inhibitors of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), nuclear factor-kappaB (NF-kB) and phosphatidylinositol 3-kinase (PI3K), were used to investigate the role of signaling pathways.
|
93 |
20451253
|
TLR agonists induced significantly elevated MCP-1, RANTES, and MIP-1.
|
94 |
20451253
|
Production of RANTES and MIP-1 was particularly prominent after stimulation of DCs with TLR3 (Poly(I:C)), and TLR7/8 (R848) or TLR9 (CpG ODN) agonists, respectively.
|
95 |
20451253
|
A positive role was identified for NF-kB, PI3K and ERK, whereas JNK had a negative regulatory effect on chemokine production in DCs.
|
96 |
20451253
|
Positive and negative regulatory roles for the p38 MAPK pathway were observed.
|
97 |
21245658
|
The cytokine (IL-4, IL-6, IL-10, IL-12 and IL-23) profiles of DCs induced by individual TLR agonists have been evaluated.
|
98 |
21245658
|
Using various mitogen-activated protein kinase (MAPK) inhibitors (c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK) and p38 MAPK) we have demonstrated the importance of p38 MAPK and ERK signaling pathways in IL-12p70 and IL-12p40 production in DCs induced by TLR stimulation, whereas the JNK pathway appeared to have a negative regulatory role on cytokine production in DCs stimulated with certain TLR agonists.

Use of Lactobacillus species to combat UTI is now giving modern concept of modern genitourinary vaccine with the facts that it not only maintains low pH of the genital area, produces hydrogen peroxide and hinders the growth of E. coli but also activates Toll-like receptor-2 (TLR2), which produces interleukin-10 (IL-10) and myeloid differentiation factor 88 (MyD88).
|
100 |
21901556

In vitro, the anti-ATR-001 antibody specifically bound to Ang II receptor type 1 and inhibited Ca(2+)-dependent signal transduction events, including protein kinase C-α translocation, extracellular signal-regulated kinase 1/2 phosphorylation (72% decrease; P=0.013), and elevation of intracellular Ca(2+) (68% decrease; P=0.017) induced by Ang II, but without inhibiting Ang II binding to the receptor.

105 |
24767856

The DEX (CRCL-GL261)-DCs were found to promote cell proliferation and cytotoxic T lymphocyte (CTL) activity of CD4(+) and CD8(+) T cells in vitro compared with DEX (GL261)-DCs, which were loaded with DEXs derived from DCs loaded with GL261 tumor cell lysates.
|
109 |
25680514
|
Moreover, depletion of CD4(+) and CD8(+) T cells significantly impaired the anti-tumor effect of DEX (CRCL-GL261)-DCs.
|
110 |
25680514
|
Finally, DEX (CRCL-GL261)-DCs were found to negatively regulate Casitas B cell lineage lymphoma (Cbl)-b and c-Cbl signaling, leading to the activation of phosphatidyl inositol 3-kinase (PI3K)/Akt and extracellular signal-regulated kinase (ERK) signaling in T cells.

Interestingly, KWV enhanced neuronal differentiation and decreased NSC proliferation even in the presence of mitogens such as epidermal growth factor and fibroblast growth factor 2.
|
112 |
25706719
|
KWV treatment of NSCs reduced the phosphorylation of extracellular signal-regulated kinase 1/2, increased mRNA expression levels of the cyclin-dependent kinase inhibitor p21, down-regulated Notch/Hairy expression levels and up-regulated microRNA miR-9, miR-29a and miR-181a.
