TNF
(increases)
Evidence: In the presence of pro-inflammatory cytokines such as tumor necrosis factor-? (TNF-?) and/or interferon-gamma (IFN-G), endothelial cell CD40 expression is markedly enhanced [6]. These cytokines, especially when combined, also induce CD40 expression in rat vascular SMC [7].

→
TNF
(increases)
Evidence: Human CASMCs (coronary artery smooth muscle cells) in culture exposed to IL (interleukin)-1beta or TNF-alpha (tumour necrosis factor-alpha) had increased superoxide generation and enhanced CD40 expression, detected by EPR (electron paramagnetic resonance) and immunoblotting respectively.

CD40
→
TNF
(increases)
Evidence: TNF and IFN-g were found to be the most effective at enhancing CD40 expression, producing about a 3-fold increase in CD40 expression after 24 h (Fig. 1). IFN-beta and IL-1a also increased CD40 expression, although somewhat less effectively than TNF or IFN-g.

Suttles et al., J Biol Chem 1999
:
Together, the data demonstrate that
CD40 mediated induction of IL-1beta and
tumor necrosis factor-alpha synthesis is dependent on a MEK/ERK pathway which is obstructed by signals generated through the action of IL-4 and IL-10
von Leoprechting et al., Cancer Res 1999
(Melanoma) :
CD40 expression could be enhanced in CD40 positive MM by
stimulation with IFN-gamma and
tumor necrosis factor-alpha but not by interleukin (IL)-1beta or CD40 triggering ...
CD40 ligation on MM by CD40L transfected murine L-cells or by a soluble CD40L fusion protein
up-regulated their expression of intercellular adhesion molecule-1 and MHC class I and class II molecules and their secretion of IL-6, IL-8,
tumor necrosis factor-a , and granulocyte macrophage colony stimulating factor and also induced a rapid activation of the transcription factor nuclear factor kappaB

CD40 induced
tumor necrosis factor-alpha in rheumatoid arthritis : a novel mechanism of activation of synoviocytes ... IL-10 exerted inhibitory effects on both
CD40 ligation induced and CD40 ligation plus IFN-gamma
induced TNF-alpha production by ST cells
Chabot et al., J Immunol 1999
:
By also measuring TNF-alpha levels, specificity of cytokine regulation was observed ; while

TNF-alpha levels, anti-CD23 did not affect TNF-alpha while attenuating IL-10 generation
Tan et al., J Neuroimmunol 1999

Arrighi et al., J Immunol 2001

induced by LPS and
TNF-alpha
Chabot et al., J Neurosci Methods 2001
(Central Nervous System Diseases...) :
Morphological features and mechanisms of cytokine production resemble those observed in microglia -- T cell co-cultures since CTLA-4 and

effects of IFN-gamma,
tumor necrosis factor-alpha (TNF-alpha), and granulocyte-macrophage colony stimulating factor ( GM-CSF ) on

Manning et al., Eur J Immunol 2002
:
The specific TRAF dependency of
CD40 induced growth arrest,
TNF-alpha production, and phosphorylation of signaling molecules are shown, while p38 MAPK activation and cell surface antigen modulation suggest TRAF independent CD40 signaling in B cells
Foey et al., Cytokine 2001
:
CD40 ligation
induces macrophage IL-10 and
TNF-alpha production : differential use of the PI3K and p42/44 MAPK-pathways ... IL-10 and
tumour necrosis factor alpha (TNF-alpha) are produced by macrophage colony stimulating factor ( M-CSF ) -primed monocytes/macrophages in
response to
CD40 ligation ... These observations suggest that
CD40 ligation
induces macrophage IL-10 and
TNF-alpha production, the mechanism of which is p70S6K dependent yet bifurcates at the level of PI3K and p42/44 MAPK
Jana et al., J Neurochem 2002
:
Regulation of
tumor necrosis factor-alpha expression by
CD40 ligation in BV-2 microglial cells ... This study delineates the mechanism by which
CD40 ligation
regulates the expression of
TNF-alpha in BV-2 microglial cells ... There was very little
induction of
TNF-alpha by ligation of
CD40 alone by either cross linking antibodies against CD40 or recombinant CD40 ligand ( CD154 ) ... However,
CD40 ligation markedly
induced the production of
TNF-alpha as well as the expression of TNF-alpha mRNA in interferon-gamma (IFN-gamma) stimulated BV-2 glial cells ... Ligation of
CD40 in CD40 overexpressed cells markedly
enhanced the expression of
TNF-alpha in the presence of IFN-gamma ... However, CD40 ligation alone in the presence or absence of CD40 overexpression induced the activation of only NF-kappaB and not that of C/EBPbeta, suggesting that the activation of NF-kappaB alone by
CD40 ligation is not sufficient to induce the expression of TNF-alpha and that the activation of C/EBPbeta is also
necessary for strong induction of
TNF-alpha ... Taken together, these studies suggest that activation of both NF-kappaB and C/EBPbeta is important for strong induction of TNF-alpha and that
CD40 ligation
regulates the expression of
TNF-alpha by modulating the activation of only NF-kappaB but not that of C/EBPbeta

Here we demonstrate that

Companjen et al., Int Immunol 2002
:
IL-6, IL-8,
tumor necrosis factor (TNF)-alpha , IL-12 and IL-1 beta were
induced upon CD40 ligation and IFN-gamma stimulation, while IL-10 could be induced by
CD40 ligation alone and was reduced again by the addition of IFN-gamma ... These data show that
CD40 ligation
induced secretion of IL-6 and IL-8, but not
TNF-alpha and IL-10, is partially mediated via IL-1 and that IL-1 plays a prominent role in the inflammatory response initiated by CD40 ligation in intact human skin

Lee et al., Proc Natl Acad Sci U S A 2005
(Diabetes Mellitus, Experimental...) :
Moreover, neonatal treatment with TNF-alpha resulted in skewed development of a CD8alpha ( + ) CD11b ( - ) CD11c ( + ) DC subset such that
TNF-alpha decreases the CD8alpha ( + ) CD11c ( + ) DC subset, increases the CD11c ( + ) CD11b ( + ) subset, and
causes an increase in the expression of
CD40 and CD54 on mature DCs capable of inducing immunity

CD40 and matrix metalloproteinase in human vascular endothelial cells ... To investigate the regulatory effects of fenofibrate on
TNF-alpha induced
CD40 expression and matrix metalloproteinase ( MMP ) activity in human vascular endothelial cells ( HUVECs ) ... Quantitative RT-PCR and flow cytometry were employed to evaluate the effect of fenofibrate on
TNF-alpha induced CD40 mRNA and cell surface
CD40 expression in HUVECs, and gelatin zymography was used to determine the effect of fenofibrate on the gelatinolytic activities of MMP-2 and MMP-9 in TNF-alpha stimulated HUVECs ...

Guanosine effects were mediated by an increased phosphorylation of Akt, a PI3K downstream effector, as well as of ERK1/2 and p38 in the MAPK system, because culture pretreatment with selective ERK1/2, p38 MAPK, and PI3K antagonists ( U0126, SB203580, or LY294002, respectively ) counteracted guanosine inhibition on

The present study was thus designed to explore the potential effect of SIRT1 on
CD40 expression
induced by
tumor necrosis factor-a (TNF-a) and to disclose the underlying mechanism in CRL-1730 endothelial cells ... Pretreatment with resveratrol ( a potent SIRT1 activator ) inhibited
TNF-a induced
CD40 expression, while pretreatment with nicotinamide ( class b HDACs inhibitor nicotinamide ) or sirtinol ( a known SIRT1 inhibitor ), especially SIRT1 siRNA significantly augmented TNF-a induced CD40 expression ... The frther sudy idicated that PDTC ( NF-?B inhibitor ) pretreatment attenuated
TNF-a induced
CD40 expression, and SIRT1 siRNA significantly augmented TNF-a induced acetylated-NF-?B p65 ( Lys310 ) expression ... Conclusion : The present study provides the direct evidence that SIRT1 can inhibit
TNF-a- induced
CD40 expression in CRL-1730 endothelial cells by deacetylating the RelA/p65 subunit of NF-?B at lysine 310, which provides new insights into understanding of the anti-inflammatory and anti-athroscerotic actions of SIRT1

We show that the
CD40 induced production of IL-6, IL-8 and

Snijders et al., Int Immunol 1998
:
The two-signal requirement proved unique for the production of IL-12, since either
CD40 engagement or LPS was
sufficient for the efficient production of
tumor necrosis factor-alpha , IL-8 and the p40 subunit of IL-12, and may be considered as a safety mechanism for optimal control of potentially harmful T ( h ) 1 responses
