Serum IL - 1beta levels in health and disease : a population-based study . ' The InCHIANTI study ' . Interleukin - 1 plays a role in normal homeostasis and in the inflammatory response which is deemed to be responsible for the development of major chronic diseases that are highly prevalent in the elderly . Aim of this study is to evaluate the factors influencing the serum levels of
P01584
REA
, in a large and representative population . Data were from the InCHIANTI project , a study of factors contributing to the decline of mobility in late life , which sampled people living in two sites in the surroundings of Florence . Blood samples were obtained from 1,292 participants and frozen aliquots were stored at - 80 degrees C . The serum levels of several cytokines were measured by enzyme linked immunosorbent assay using an ultrasensitive commercial kit .
P01584
REA
serum levels were associated with congestive heart failure ( p > 0.001 ) and angina ( p = 0.02 ) , with Ca2 + serum levels ( p = 0.02 ) , and with a history of dyslipidemia ( p = 0.05 ) . We found no association between serum IL - 1beta level and age , sex , consumption of cardioactive drugs and serum levels of IL - 1Ra ,
P05231
REA
, sIL - 6R ,
P22301

inhibits the activation of
P09619
REA
β-expressing astrocytes in the brain metastatic microenvironment of breast cancer cells . Brain metastases occur in more than one-third of metastatic breast cancer patients whose tumors overexpress
P04626
REA
or are triple negative . Brain colonization of cancer cells occurs in a unique environment , containing microglia , oligodendrocytes , astrocytes , and neurons . Although a neuroinflammatory response has been documented in brain metastasis , its contribution to cancer progression and therapy remains poorly understood . Using an experimental brain metastasis model , we characterized the brain metastatic microenvironment of brain tropic ,
P04626
REA
- transfected MDA-MB - 231 human breast carcinoma cells ( 231 - BR -
P04626
REA
) . A previously unidentified subpopulation of metastasis-associated astrocytes expressing phosphorylated platelet-derived growth factor receptor β ( at tyrosine 751 ; p751 -
P09619

β ) was identified around perivascular brain micrometastases . p751 -
P09619
REA
β ( + ) astrocytes were also identified in human brain metastases from eight craniotomy specimens and in primary cultures of astrocyte-enriched glial cells . Previously , we reported that pazopanib , a multispecific tyrosine kinase inhibitor , prevented the outgrowth of 231 - BR -
P04626
REA
large brain metastases by 73 % . Here , we evaluated the effect of pazopanib on the brain neuroinflammatory microenvironment .
DB06589
MEN
treatment resulted in 70 % ( P = 0.023 ) decrease of the p751 -
P09619
REA
β ( + ) astrocyte population , at the lowest dose of 30 mg / kg , twice daily . Collectively , the data identify a subpopulation of activated astrocytes in the subclinical perivascular stage of brain metastases and show that they are inhibitable by pazopanib , suggesting its potential to prevent the development of brain micrometastases in breast cancer patients .

Attenuation of experimental autoimmune myocarditis by blocking activated T cells through inducible costimulatory molecule pathway . OBJECTIVE : Inducible costimulator (
Q9Y6W8
REA
) is a member of the
P10747
REA
family . Although inflammation is an essential pathological feature of myocarditis , the role of
Q9Y6W8
REA
in myocarditis remains unclear . METHODS AND RESULTS : Lewis rats were immunized on day 0 with purified porcine cardiac myosin to establish experimental autoimmune myocarditis ( EAM ) . Flow cytometry was used to examine expression of
Q9Y6W8
REA
on myocardial infiltrating cells . Anti -
Q9Y6W8
REA
antibody or
Q9Y6W8
REA
- immunoglobulin ( ICOSIg ) was administered intravenously , and rats were killed on day 14 or 21 to study effects of
Q9Y6W8
REA

Q9Y6W8
REA
- ligand (
O75144
REA
) pathway blockade during the antigen priming phase ( days 0-14 ) or immune response phase ( days 14-21 ) , respectively . The heart weight to body weight ratio was determined , and histological examination and echocardiogram were performed to evaluate the severity of the disease . Cytokine expression in the heart and T cell proliferation against cardiac myosin were analyzed . Flow cytometry revealed that the majority of infiltrating cells , especially
P01730
REA
- positive cells , expressed
Q9Y6W8
REA
. Blockade of the
Q9Y6W8
REA
/
O75144
REA
pathway during the immune response phase attenuated EAM development . However , blockade of the
Q9Y6W8
REA
/
O75144
REA
pathway during the antigen priming phase did not attenuate and exacerbate EAM . Blockade of T cell activation through
Q9Y6W8
REA
suppressed expression of cytokines including
P27352
REA
- gamma ,
P05112
REA
,
P05231
REA
,
P22301
REA
,
P01584
REA
, and
P01375
REA
and inhibited T cell proliferation in vitro . CONCLUSIONS : Blockade of T cell activation through
Q9Y6W8
REA
during the immune response phase regulates development of EAM , and therefore ,
Q9Y6W8
REA
may be an effective target for treating myocarditis .

Interaction of tacrolimus ( FK506 ) and its metabolites with FKBP and calcineurin .
DB00864
MEN
( FK506 ) is a strong immuno-suppressant and shows its activity through inhibiting
P60568
REA
mRNA transcription by forming pentameric complex with intracellular receptor ( FK506 binding protein 12 kDa or
P62942
REA
) , Ca2 + , calmodulin , and calcineurin . Here , we report the binding activity to
P62942
REA
, the pentameric complex formation and Con-A response inhibiting activities of 7 metabolites . C15 - demethylated metabolite ( M - 3 ) needed higher quantity to compete in Con-A assay and in pentamer formation assay , although it binds more strongly to
P62942
REA
. The result suggests that the ability to form a pentameric complex is not a two step reaction with the first binding to
P62942
REA
, but a single step reaction by components for the pentamer formation .

Knockdown of
Q03426
REA
does not lead to changes in
Q96P20
REA
expression or activation . BACKGROUND : Mutations in the Mevalonate Kinase gene (
Q03426
REA
) are causes of a rare autoinflammatory disease : Mevalonate Kinase Deficiency and its more acute manifestation , Mevalonic Aciduria . The latter is characterized , among other features , by neuroinflammation , developmental delay and ataxia , due to failed cerebellar development or neuronal death through chronic inflammation . Pathogenesis of neuroinflammation in Mevalonate Kinase Deficiency and Mevalonic Aciduria has not yet been completely clarified , however different research groups have been suggesting the inflammasome complex as the key factor in the disease development . A strategy to mimic this disease is blocking the mevalonate pathway , using
P04035
REA
inhibitors ( Statins ) , while knock-out mice for Mevalonate Kinase are non-vital and their hemyzygous ( i . e only one copy of gene preserved ) littermate display almost no pathological features . FINDINGS : We sought to generate a murine cellular model closely resembling the pathogenic conditions found in vivo , by direct silencing of Mevalonate Kinase gene . Knockdown of Mevalonate Kinase in a murine microglial cellular model ( BV - 2 cells ) results in neither augmented
Q96P20
REA
expression nor increase of apoptosis . On the contrary , statin treatment of BV - 2 cells produces an increase both in Mevalonate Kinase and
Q96P20
REA
expression . CONCLUSIONS : MKD deficiency could be due or affected by protein accumulation leading to
Q96P20
REA
activation , opening novel questions about strategies to tackle this disease .

IL - 1 transcriptionally activates the neutrophil chemotactic factor /
P10145
REA
gene in endothelial cells . Leucocytes and vascular cells interact closely in inflammation and immunity and cytokines are important mediators of this interaction . The present study was designed to define the capacity of human endothelial cells (
O14777
REA
) to produce a monocyte-derived neutrophil chemotactic factor ( provisionally termed
P10145
REA
) .
P10145
REA
is a polypeptide chemotactic for neutrophils originally identified in the culture supernatant of lipopolysaccharide ( LPS ) - stimulated monocytes . IL - 1 induced high levels of production of neutrophil chemotactic activity in culture supernatants of
O14777
REA
. Optimal stimulation of activity was observed when
O14777
REA
were cultured with 10-100 ng / ml
P01584
REA
for 16 hr . Anti -
P10145
REA
antibody blocked the chemotactic activity for neutrophils of IL - 1 - activated
O14777
REA
supernatants . IL - 1 - treated
O14777
REA
expressed high levels of
P10145
REA
mRNA transcripts , as assessed by Northern blot analysis . Tumour necrosis factor (
P01375
REA
) and LPS , unlike the inflammatory monokine
P05231
REA
, also induced
P10145
REA
expression . Nuclear run-off experiments revealed that IL - 1 activated transcription of the
P10145
REA
gene . The production of
P10145
REA
may represent a mechanism whereby endothelial cells , exposed to inflammatory signals , participate in the regulation of neutrophil extravasation .

Methodological challenges in monitoring new treatments for rare diseases : lessons from the cryopyrin-associated periodic syndrome registry . BACKGROUND : The
Q96P20
REA
- Associated Periodic Syndromes ( CAPS ) are a group of rare hereditary autoinflammatory diseases and encompass Familial Cold Autoinflammatory Syndrome ( FCAS ) , Muckle-Wells Syndrome ( MWS ) , and Neonatal Onset Multisystem Inflammatory Disease ( NOMID ) .
DB06168
SUB
is a monoclonal antibody directed against
P01584
REA
and approved for CAPS patients but requires post-approval monitoring due to low and short exposures during the licensing process . Creative approaches to observational methodology are needed , harnessing novel registry strategies to ensure Health Care Provider reporting and patient monitoring . METHODS : A web-based registry was set up to collect information on long-term safety and effectiveness of canakinumab for CAPS . RESULTS : Starting in November 2009 , this registry enrolled 241 patients in 43 centers and 13 countries by December 31 , 2012 . One-third of the enrolled population was aged < 18 ; the overall population is evenly divided by gender . Enrolment is ongoing for children . CONCLUSIONS : Innovative therapies in orphan diseases require post-approval structures to enable in depth understanding of safety and natural history of disease . The rarity and distribution of such diseases and unpredictability of treatment require innovative methods for enrolment and follow-up . Broad international practice-based recruitment and web-based data collection are practical .

[ Preparation of NK-enriched Q96QP1 cells - - their potential cytotoxic and ADCC activities ] . We examined several culture methods to induce proliferation of natural killer ( NK ) cells from peripheral blood mononuclear cells ( PBMC ) . In the presence of
P60568
REA
, a remarkable proliferation of NK cells was observed when PBMC were co-cultured with DB00305 - treated K562 , which is known as a highly sensitive in vitro target cell for the NK assay . Addition of OK - 432 or
P01375
REA
and
P01584
REA
also induced marked NK proliferation in a dose dependent manner . These NK-enriched lymphokine activated killer ( Q96QP1 ) cells showed highly cytotoxic activities against various MHC class I positive or negative tumor cells . They also showed potent ADCC activities against Herceptin-coated SK-BR - 3 , a
P04626
REA
/ neu positive breast cancer cell line . These results indicated that NK-enriched Q96QP1 cells are potent effector cells , and suggested novel therapeutic strategies for nonspecific immunotherapy as well as target immunotherapy in combination with anticancer antibodies , such as Herceptin .

Inhibition of histamine H1 receptor activity modulates proinflammatory cytokine production of dendritic cells through c-Rel activity . BACKGROUND : DB11320 exerts diverse effects on immune regulation through four types of histamine receptors ( HRs ) . Among them , type 1 receptor (
P35367
REA
) plays an important role in allergic inflammation . Dendritic cells ( DCs ) , which express at least three types of HRs , are professional antigen-presenting cells controlling the development of allergic inflammation . However , the molecular mechanisms involved in
P35367
REA
- mediated NF-ĸB signaling of DCs remain poorly defined . METHODS : Bone-marrow ( BM ) - derived DCs ( BM-DCs ) were treated with
P35367
REA
inverse agonists to interrupt basal
P35367
REA
- mediated signaling . The crosstalk of
P35367
REA
- mediated signaling and the NF-ĸB pathway was examined by NF-ĸB cellular activity using a luciferase reporter assay , NF-ĸB subunit analysis using Western blotting and
P01375
REA
- α promoter activity using chromatin immunoprecipitation . RESULTS : Blockage of
P35367
REA
signaling by inverse agonists significantly inhibited
P01375
REA
- α and
P05231
REA
production of BM-DCs .
P35367
REA
- specific agonists were able to enhance
P01375
REA
- α production , but this overexpression was significantly inhibited by NF-ĸB inhibitor . The
P35367
REA
inverse agonist ketotifen also suppressed cellular NF-ĸB activity , suggesting crosstalk between
P35367
REA
and NF-ĸB signaling in DCs . After comprehensive analysis of NF-ĸB subunits , c-Rel protein expression was significantly down-regulated in ketotifen-treated BM-DCs , which led to inhibition of the promoter activity of
P01375
REA
- α . Finally , adoptive transfer of the ketotifen-treated BM-DCs did not induce significant allergic airway inflammation compared to that of control cells in vivo . CONCLUSIONS : Our results suggest that c-Rel controls
P35367
REA
- mediated proinflammatory cytokine production in DCs . This study provides a potential mechanism of
P35367
REA
- mediated signaling and NF-ĸB pathway crosstalk in allergic inflammation .

inhibitors up-regulate anti-aging klotho mRNA via RhoA inactivation in IMCD 3 cells . OBJECTIVE : Q9UEF7 is thought to play a critical role in the development of age-related disorders including arteriosclerosis . Statins may exert vascular protective effects , independent of the lowering of plasma cholesterol levels . We investigated the impact of statins on mRNA expression of the age-suppressor gene , klotho in mIMCD 3 cells . METHODS AND RESULTS : Q9UEF7 mRNA levels were evaluated with real-time RT-PCR .
DB01076
MEN
and pitavastatin increased the expression of klotho mRNA in a dose-dependent manner . This stimulatory effect was abolished by the addition of mevalonate , GGPP and FPP , essential molecules for isoprenylation of the small GTPase Rho . As was the case with the statin treatment , inhibition of Rho-kinase by Y27632 up-regulated klotho mRNA . In contrast to the statin treatment , stimulation with angiotensin II down-regulated klotho mRNA expression without obvious morphological changes . Furthermore , pretreatment with atorvastatin blunted the angiotensin II-induced response and ameliorated the decrease in klotho mRNA expression towards basal levels . RhoA activity was further evaluated by detection of its translocation . Angiotensin II activated RhoA , whereas statins potently inactivated RhoA and blocked RhoA activation by angiotensin II . CONCLUSION : Statins inactivate the RhoA pathway , resulting in over-expression of klotho mRNA , which may contribute to the novel pleiotropic effects of statins towards vascular protection .

In this study , we investigated the effects of vortioxetine on the period length of O15055 :: LUC expression , circadian behavior , and episodic memory , using tissue explants from genetically modified O15055 :: LUC mice , locomotor activity rhythm monitoring , and the object recognition test , respectively . Incubation of tissue explants from the suprachiasmatic nucleus of O15055 :: LUC mice with 0.1 μM vortioxetine increased the period length of O15055 bioluminescence . Monitoring of daily wheel-running activity of Sprague-Dawley rats treated with vortioxetine ( 10 mg / kg , s . c . ) , alone or in combination with the
P08908
REA
receptor agonist flesinoxan ( 2.5 mg / kg , s . c . ) or the
P34969
REA
receptor antagonist SB269970 ( 30 mg / kg , s . c . ) , just prior to activity onset revealed significant delays in wheel-running behavior . The increase in circadian period length and the phase delay produced by vortioxetine were abolished in the presence of the
P34969
REA
receptor partial agonist AS19 . Finally , in the object recognition test , vortioxetine ( 10 mg / kg , i . p . ) increased the time spent exploring the novel object during the retention test and this effect was prevented by AS19 ( 5 mg / kg , i . p . ) . In conclusion , the present study shows that vortioxetine , partly via its
P34969
REA
receptor antagonism , induced a significant effect on circadian rhythm and presented promnesic properties in rodents .

Evidence for a role of the
P28335
REA
receptor in central lipopolysaccharide - , interleukin - 1 beta - , and leptin-induced anorexia . We examined the role of serotonin ( 5 - HT ) and the 5 - HT ( 1A ) and 5 - HT ( 2C ) receptors in the anorectic effects of centrally administered lipopolysaccharide ( LPS ) , interleukin - 1 beta (
P01584
REA
) , and leptin . Food intake was measured in rats after intracerebroventricular ( ICV ) injections of LPS ( 20 ng ) ,
P01584
REA
( 10 ng ) , or leptin ( 1 microg ) at lights out , followed by intraperitoneal ( IP ) injections of either the 5 - HT ( 1A ) autoreceptor agonist 8 - hydroxy - 2 - ( di-n-propylamino ) tetraline ( 8 - OH-DPAT ) ( 125 microg / kg ) or the 5 - HT ( 2C ) receptor antagonist SB 242084 ( 0.3 mg / kg ) at the onset of anorexia . SB 242084 significantly attenuated the food intake reduction caused by all compounds ( all P < . 01 ) . IP 8 - OH-DPAT attenuated ICV
P01584
REA
- induced anorexia ( P < . 01 ) . We also tested the involvement of the median raphe 5 - HT ( 1A ) receptors in peripheral LPS - and
P01584
REA
- induced anorexia . Rats were injected intraperitoneally with either LPS ( 100 microg / kg ) or
P01584
REA
( 2 microg / kg ) at lights out , and 8 - OH-DPAT ( 4 nmol ) was administered directly into the median raphe nucleus at the onset of anorexia . Median raphe injections of 8 - OH-DPAT significantly attenuated both
P01584
REA
- and LPS-induced anorexia ( both P < . 01 ) . These results implicate the 5 - HT ( 2C ) receptors in the mediation of central LPS - ,
P01584

inhibition reduces atherosclerotic plaque neovessel formation and regresses advanced atherosclerotic plaques . OBJECTIVE : The interaction between the renin-angiotensin system and toll-like receptors ( TLRs ) in the pathogenesis of advanced atherosclerotic plaques is not well understood . We studied the effects of the renin inhibitor aliskiren on the progression of advanced atherosclerotic plaque in apolipoprotein E-deficient ( ApoE ( - / - ) ) mice with a special focus on plaque neovessel formation . METHODS AND RESULTS : Four-wk-old ApoE ( - / - ) mice were fed a high-fat diet for 8 wks , and the mice were randomly assigned to one of three groups and administered a vehicle , hydralazine , or aliskiren for an additional 12 wks .
DB09026

also decreased the levels of AT1R , gp91phox ,

, monocyte chemotactic protein - 1 , and CatS mRNAs in the aortic roots . DB01275 had no beneficial vascular effects , although its administration resulted in the same degree of blood pressure reduction as aliskiren . CatS deficiency mimicked the aliskiren-mediated vasculoprotective effect in the ApoE ( - / - ) mice , but aliskiren showed no further benefits in ApoE ( - / - ) CatS ( - / - ) mice . In vitro ,
O60603
REA
silencing reduced CatS expression induced by angiotensin II . Moreover , aliskiren or the inhibition of CatS impaired the endothelial cell angiogenic action in vitro or / and ex vivo . CONCLUSION :
P00797
REA
inhibition appears to inhibit advanced plaque neovessel formation in ApoE ( - / - ) mice and to decrease the vascular inflammatory action and extracellular matrix degradation , partly by reducing AT1R /

Changes of Dietary Fat and Carbohydrate Content Alter Central and Peripheral Clock in Humans . CONTEXT : The circadian clock coordinates numerous metabolic processes with light-dark and feeding regimens . However , in humans it is unknown whether dietary patterns influence circadian rhythms . OBJECTIVE : We examined the effects of switching from a high-carbohydrate , low-fat diet to a low-carbohydrate , high fat ( LC / HFD ) isocaloric diet on the central and peripheral circadian clocks in humans . DESIGN : Diurnal patterns of salivary cortisol and gene expression were analyzed in blood monocytes of 29 nonobese healthy subjects before and 1 and 6 weeks after the dietary switch . For this , we established a method of rhythm prediction by 3 - time point data . RESULTS : The centrally driven cortisol rhythm showed a phase delay 1 and 6 weeks after the dietary switch to a LC / HFD as well as an amplitude increase . The dietary switch altered diurnal oscillations of core clock genes ( O15534 , O15055 , P56645 , and Q10587 ) and inflammatory genes (
P08571
REA
,
Q99467
REA
,
P25963
REA
, and
P01584

) . The LC / HFD also affected the expression of nonoscillating genes contributing to energy metabolism ( Q96EB6 ) and fat metabolism (
O15254
REA
and
P50213
REA
) . Expression of clock genes but not of salivary cortisol in monocytes tightly correlated with levels of blood lipids and with expression of metabolic and inflammatory genes . CONCLUSIONS : Our results suggest that the modulation of the dietary fat and carbohydrate content alters the function of the central and peripheral circadian clocks in humans .

antagonist cetirizine impairs working memory processing speed , but not episodic memory . BACKGROUND AND PURPOSE : The histaminergic neurotransmitter system is currently under investigation as a target for drug treatment of cognitive deficits in clinical disorders . The therapeutic potential of new drugs may initially be screened using a model of histaminergic dysfunction , for example , as associated with the use of centrally active antihistamines . Of the selective second generation antihistamines , cetirizine has been found to have central nervous system effects . The aim of the present study was to determine whether cetirizine can be used as a tool to model cognitive deficits associated with histaminergic hypofunction . EXPERIMENTAL APPROACH : The study was conducted according to a three-way , double-blind , cross-over design . Treatments were single oral doses of cetirizine 10 and 20 mg and placebo . Effects on cognition were assessed using tests of word learning , memory scanning , vigilance , divided attention , tracking and visual information processing speed . KEY RESULTS :

10 mg impaired tracking performance and both doses impaired memory scanning speed . None of the other measures indicated impaired performance . CONCLUSION AND IMPLICATIONS :

affects information processing speed , but these effects were not sufficient to serve as a model for cognitive deficits in clinical disorders .

Serum amyloid A activates the
Q96P20
REA
inflammasome via
Q99572
REA
receptor and a cathepsin B-sensitive pathway . Serum amyloid A ( P0DJI8 ) is an acute-phase protein , the serum levels of which can increase up to 1000 - fold during inflammation . P0DJI8 has a pathogenic role in amyloid A-type amyloidosis , and increased serum levels of P0DJI8 correlate with the risk for cardiovascular diseases . IL - 1β is a key proinflammatory cytokine , and its secretion is strictly controlled by the inflammasomes . We studied the role of P0DJI8 in the regulation of IL - 1β production and activation of the inflammasome cascade in human and mouse macrophages , as well as in THP - 1 cells . P0DJI8 could provide a signal for the induction of pro-IL - 1β expression and for inflammasome activation , resulting in secretion of mature IL - 1β . Blocking

attenuated P0DJI8 - induced expression of
P01584
REA
, whereas inhibition of caspase - 1 and the DB00171 receptor P2X ( 7 ) abrogated the release of mature IL - 1β .
Q96P20
REA
inflammasome consists of the
Q96P20
REA
receptor and the adaptor protein apoptosis-associated speck-like protein containing CARD ( a caspase-recruitment domain ) ( ASC ) . P0DJI8 - mediated IL - 1β secretion was markedly reduced in ASC ( - / - ) macrophages , and silencing
Q96P20
REA
decreased IL - 1β secretion , confirming
Q96P20
REA
as the P0DJI8 - responsive inflammasome . Inflammasome activation was dependent on cathepsin B activity , but it was not associated with lysosomal destabilization . P0DJI8 also induced secretion of cathepsin B and ASC . In conclusion , P0DJI8 can induce the expression of pro-IL - 1β and activation of the
Q96P20
REA
inflammasome via P2X ( 7 ) receptor and a cathepsin B-sensitive pathway . Thus , during systemic inflammation , P0DJI8 may promote the production of IL - 1β in tissues . Furthermore , the P0DJI8 - induced secretion of active cathepsin B may lead to extracellular processing of P0DJI8 and , thus , potentially to the development of amyloid A amyloidosis .
