Small angle neutron scattering (SANS) measurements were performed on solutions of cAMP receptor protein (CRP) and on solutions of the T127L,S128A double mutant of CRP (CRP*) in D2O K3PO4 buffer containing 0.5 M KCl, in the absence and presence of 3',5' cyclic adenosine monophosphate (cAMP). Energy-minimized structures of the CRP were calculated by minimization of the x-ray crystallographic stru...

TfoX (Sxy) and CRP are two important competence activators. The link between tfoX and CRP has been shown in H. influenza but lacking evidence of direct interaction. Recently a Sxy-dependent CRP (CRP-S) site autoregulating Sxy was reported in E. coli. Here, we show that the cAMP-CRP complex transcriptionally regulates tfoX expression through multiple canonical CRP (CRP-N) sites in Vibrios. This ...

BACKGROUND C-reactive protein (CRP) is widely used to detect bacterial infection in children. We investigated the impact of CRP test results on decision-making and summarized the evidence base (EB) of CRP testing. METHODS We collected information from the hospital records of 91 neonates with suspected sepsis and of 152 febrile children with suspected infection on the number of ordered CRP tes...

Biosynthetic labeling with [35S]met and immunoprecipitation with anti-C-reactive protein (CRP) antibodies and Staphylococcus aureus indicate that cell surface CRP is produced by lymphocytes. The ability of anti-CRP to reduce NK activity, and the demonstration that 125I-anti-CRP-labeled PBL are found in low-density Percoll fractions associated with large granular lymphocyte (LGL) and NK activity...

BACKGROUND AND OBJECTIVES Carotid intima-media thickness (IMT) is associated with chronic inflammation, and C-reactive protein (CRP) level is elevated in patients with atrial fibrillation (AF). We investigated the impacts of CRP and AF on carotid atherosclerosis and ischemic stroke in patients with suspected ischemic cerebrovascular disease. SUBJECTS AND METHODS One-hundred forty patients (78...

OBJECTIVE We aimed to detect C-reactive protein (CRP) in neonatal saliva and evaluate its diagnostic utility. STUDY DESIGN Salivary and serum samples (n = 89) were collected from 40 neonates. Salivary CRP levels were determined using an enzyme-linked immunosorbent assay; serum CRP was measured per hospital protocol. Correlation coefficients with 95% confidence intervals and robust linear regr...

BACKGROUND Visceral obesity (VO) is associated with an increased risk of cardiovascular disease. Elevated C-reactive protein (CRP) levels are associated with VO and cardiovascular disease. After exploring the relation between CRP and VO, we aimed to evaluate the VO independent relation between CRP and carotid atherosclerosis. METHODS AND RESULTS The prevalence of inflammation was evaluated in...

BACKGROUND Elevated levels of serum C-reactive protein (CRP) have been reported to have prognostic significance in lung cancer patients. This study aimed to further identify CRP-bound components as prognostic markers for lung cancer and validate their prognostic value. METHODS CRP-bound components obtained from the serum samples from lung cancer patients or healthy controls were analyzed by d...

We examined the effect of purified human C-reactive protein (CRP) on induction of human peripheral blood monocyte (Mo)-mediated cytotoxicity (CTX) and oxidative metabolism. Exposure of Mo to acute phase serum levels of CRP in vitro resulted in dose-dependent expression of CTX against human tumor cell lines. Nonneoplastic human fibroblasts and glial cells were not affected by CRP-exposed Mo, and...
