The mechanisms underlying leptin resistance are still being defined. We report here the presence in human blood of several serum leptin-interacting proteins (SLIPs), isolated by leptin-affinity chromatography and identified by mass spectrometry and immunochemical analysis. We confirmed that one of the major SLIPs is C-reactive protein (CRP). In vitro, human(More)
Complement is important for elimination of invasive microbes from the host, an action achieved largely through interaction of complement-decorated pathogens with various complement receptors (CR) on phagocytes. Pneumococcal surface protein A (PspA) has been shown to interfere with complement deposition onto pneumococci, but to date the impact of PspA on(More)
OBJECTIVE Previously we established that the vascular injury response was attenuated in ovariectomized wild-type rodents treated with 17beta-estradiol (E2). We also showed that the response to acute vascular injury in transgenic mice expressing human C-reactive protein (CRPtg) is exaggerated compared with their nontransgenic (NTG) counterparts. Herein we(More)
BACKGROUND The UK Health and Safety Executive's (HSE) Management Standards (MS) approach has been developed to help organizations manage potential sources of work-related stress. Although there is general support for the assessment model adopted by this approach, to date, there has been no empirical investigation of the relationship between the actual MS(More)
OBJECTIVES To determine if a polymorphic GTn repeat in the intron of the C-reactive protein (CRP) gene associates with occurrence of vascular arterial events in systemic lupus erythematosus (SLE). METHODS We performed a nested case-control study on the LUMINA cohort of 546 Hispanic, African-American and Caucasian SLE patients. Twenty-five patients who(More)
BACKGROUND We previously demonstrated that vascular injury-induced neointima formation is exaggerated in human C-reactive protein (CRP) transgenic (CRPtg) compared to nontransgenic (NTG) mice. We now test the hypothesis that complement is required for this effect. METHODS AND RESULTS CRPtg and NTG with a normal complement system versus their counterparts(More)
Renal ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury (AKI), occurring with hypotension and cardiovascular surgery and inevitably during kidney transplantation. Mortality from AKI is high due to incomplete knowledge of the pathogenesis of IRI and the lack of an effective therapy. Inflammation accompanies IRI and increases the(More)
BACKGROUND Plasma C-reactive protein (CRP) concentration is a strong predictor of atherosclerosis. However, to date, there is no in vivo evidence that CRP is proatherogenic. METHODS AND RESULTS We studied the effect of human CRP transgene (tg) expression, under basal and turpentine-stimulated conditions, on atherosclerosis in apolipoprotein (apo) E-/-(More)
To investigate whether functional polymorphisms exist in the C-reactive protein (CRP) gene, i.e., ones that contribute directly to differences in baseline CRP among individuals, we sequenced a 1,156-nucleotide-long stretch of the CRP gene promoter in 287 ostensibly healthy people. We identified two single-nucleotide polymorphisms (SNPs), a bi-allelic one at(More)
OBJECTIVE Human C-reactive protein (CRP) binds apoptotic cells and alters blood clearance of injected chromatin in mice. To test whether CRP participates in the pathogenesis of systemic lupus erythematosus (SLE), we examined disease development in lupus-prone (NZB x NZW)F(1) (NZB/NZW) mice expressing a human CRP transgene (hCRPtg/BW).
