These findings suggest small peptides may represent a viable approach for the treatment of acute coronary syndrome and atherosclerosis in humans. Despite these favorable features, several adverse effects have been noted in preclinical studies, including elevations in blood triglycerides (TG) and cytotoxic responses (ALT, AST and creatine kinase) at high doses. To address these issues, we established a screening paradigm involving >200 analogs of ATI-5261, a novel apoE mimetic peptide and ABCA1 ligand that stimulates cellular cholesterol efflux with high potency. Safety profiles of peptides were evaluated in mice and rats, and anti-atherosclerosis effects in apoE deficient (apoE-/-) mice fed high-fat western-diet (HFWD) for 14 weeks. These studies revealed the TG elevating effects and cytotoxic responses of class A a-helical peptides were governed by a different set of molecular determinants apart from those of ABCA1 mediated cholesterol efflux. A lead peptide (CS6253) emerged with improved safety features that retained the favorable drugability properties (i.e. solubility), potent and selective cholesterol efflux activity via ABCA1 (km= 0.26±0.14 vs. 0.25±0.04 uM for ATI-5261, respectively), and mediated high affinity binding to ABCA1 as well as produced nascent HDL similar to full-length apoA-I. In vivo CS6253 stimulated macrophage specific RCT and reduced (32%) substantial atherosclerosis in apoE-/- mice when administered (SQ or IP) at a dose of 30 mg/kg over 6 weeks. These structure-activity studies from lead optimization of the ATI-5261 peptide series provide new and exciting insights for improving the therapeutic potential of apo mimetic peptides.

The purpose of this work is to describe a simplified experimental protocol that can be used in the determination of cholesterol efflux from macrophages cultured cells and be brought to a medium throughput volume. The cellular cholesterol efflux assay is designed to quantify the rate of cholesterol efflux from cultured cells to an acceptor particle or to plasma. This assay is multi step, cell based assay. Various factors, if not carefully controlled may influence the accuracy and reproducibility of the assay. Attempts were made to address factors influencing this assay and to provide a standardized method that is relatively rapid and scalable. We demonstrate that further centrifugation of the HDL fraction is necessary to avoid apolipoprotein B contamination when using polyethylene glycol (PEG) method. We demonstrate also no effect on cholesterol efflux efficiency when using PEG with plasma or serum. This method has been previously applied in our laboratory in context of cardiovascular research, cardiovascular disease and pharmacologic therapies.

The purpose of this study was to develop a random amplified polymorphic DNA (RAPD) analysis for the routine typing of these strains. Sixty P. aeruginosa non-repetitive strains recovered from CFP in a teaching hospital were typed. Thirty-five non-serotyped strains were studied by RAPD-PCR analysis with primers 272 and 208. RAPD data were performed to establish the relatedness between bioptype, antibiotic susceptibility and genotype. Fifty-five percent of strains are multiresistant, and no relation was found between antibiotype and biotype. A possible correlation between various phenotypes belonging to a single genotype was observed. RAPD typing characterized 30 distinct genotypes and two small clusters of strains were observed among isolates with each primer. Strains belonging to one cluster were present in two (6%) of the 35 strains. Strains belonging to the other cluster were present in three (8%) of the 35 strains. The occurrence of these clusters indicates that cross-infection may occur. The results indicate also that only the RAPD method can establish a clonal relation whereas the other methods may only reflect phenotypical differences, and thus are inadequate to type these strains.

We and others have previously showed that APN receptor 2 (adipoR2) pathway is impaired in foam cells when compared to macrophages. Nevertheless, the functional role of adipoR2 pathway in foam cells has not been fully investigated. We hypothesize that APN kinetics involving AdipoR2 and its subsequent downstream signaling peroxisome proliferator-activated receptor-α (PPAR-α) expression are altered in foam cells when compared to macrophages. Methods: We used THP-1 human macrophage-derived foam cells loaded with oxidized LDL (60μg/ml) and 3H-cholesterol (2μCi/ml) versus control macrophages. APN isomers and PPAR-α protein expression were detected by gradient SDS-PAGE, and Western blotting, respectively. Media cell cultures mixtures were analysed under protease inhibitor by a size-exclusion centrifugal filter molecular weight cut-off 10 kDa. Results: PPAR-α activation significantly increased in APN-treated macrophages (24h) when compared with APN-treated foam cells (24h) with a maximum fold difference of 1.90±1.21, p=0.002 at 10μg APN/mL (PPAR-α: β actin ratio, spectral count; n=10 repeats for each). As a result, in foam cells, APN stimulated PPAR-α with a lower Km molar efficiency (0.06 ± 0.13 μM) and lower velocity Vmax 0.67±0.08 /h-as compared to macrophages (0.023±0.02 μM and 1.37±0.11 /h respectively, p=0.01 for both). In macrophages, APN had smaller dissociation constant Kd (0.037±0.56 μM) than in foam cells (0.10±1.30 μM). APN increased significantly PPAR-α activity rate over time reaching a maximum of 2h, with 1.19±0.02 PPAR-α protein expression in macrophages vs 0.85±0.057 in foam cells. Additionally, the APN dimer/monomer ratio increased over 24h when compared to foam cells, reaching a maximum at 2h in macrophages. Strong correlations were noted between PPARα and APN dimers: in macrophages (r=0.85; p=0.006) and in foam cells (r=0.68, p=0.05). Conclusion: APN stimulates PPARα activity in macrophages, but significantly less in foam cells (weaker kinetic affinity process), suggesting that APN interaction and binding with adipoR2 and subsequent downstream PPARα expression are affected in foam cells.

Adiponectin is the most abundantly secreted adipokine that possesses anti-inflammatory and vasculoprotective properties via interaction with transmembrane receptors, AdipoR1 and AdipoR2. Evidence suggests that low levels of adiponectin may be a useful marker for atherosclerotic disease. A proposed anti-atherogenic mechanism of adiponectin involves its ability to promote cholesterol efflux. We performed a systematic review of the role of adiponectin in cholesterol efflux and HDL biogenesis, and of the proteins and receptors believed to be implicated in this process. Nineteen eligible studies (7 clinical, 11 fundamental, 1 clinical + fundamental) were identified through Ovid Medline, Ovid Embase, and Pubmed, that support the notion that adiponectin plays a key role in promoting ABCA1-dependent cholesterol efflux and in modulating HDL biogenesis via activation of the PPAR-γ/LXR-α signalling pathways in macrophages. AdipoR1 and AdipoR2 are suggested to also be implicated in this process, however the data are conflicting/ insufficient to establish any firm conclusions. Once the exact mechanisms are unravelled, adiponectin may be critical in defining future treatment strategies directed towards increasing HDL functionality and ultimately reducing atherosclerotic disease.

However, involvement of the apoA-I residues in this process have not been studied. In Tamm-Horsfall 1 (THP-1) macrophages and baby hamster kidney (BHK) cells we assessed adiponectin's potential to restore cholesterol efflux in the presence of apoA-I and ABCA1 mutants, respectively. Adiponectin was unable to restore efflux from THP-1 macrophages in the presence of apoA-I carboxy-terminal domain (CTD) successive mutants from residues 187-243 versus apoA-I mutants alone. Furthermore, adiponectin did not significantly influence cholesterol efflux to apoA-I from BHK-ABCA1 mutant cells. Adiponectin appears to require functional apoA-I CTD residues 187-243 and wild-type ABCA1 to mediate efficient cholesterol efflux from THP-1 macrophages and BHK cells, respectively. Therefore, adiponectin cannot rescue defective cholesterol efflux in apoA-I- or ABCA1-mutant conditions, but rather increases cholesterol efflux in wild-type apoA-I conditions compared to apoA-I exposure alone.

There are differences in AVC by sex, with women having a lower burden of calcification than men, but the mechanism for this is unclear. Improved HDL functionality has been associated with protection against coronary artery calcification, but its relationship to AVC is less studied. Methods: We evaluated measures of high-density lipoprotein (HDL) functionality in 46 patients with severe AS, n= 30 men, n=16 women. ATP-Binding Cassette A1 (ABCA1) mediated cholesterol efflux capacity (CEC) was measured from human cultured Tamm-Horsfall protein 1 (THP-1) macrophages to apoB-depleted patient plasma samples. Lipid profile, lecithin-cholesterol acyltransferase activity (LCAT), fast protein liquid chromatography (FPLC), HDL size, and small pre-β1 and α-HDL particles, were measured in apolipoprotein B-depleted patient plasma. Proteomic analysis was used to explore sex-based differences in the HDL proteome. Results: Women with severe AS had higher ABCA1-mediated CEC, as compared to men (n=46, p=0.04). We found differences in FPLC profiles between sexes in severe AS along with a reduction in preβ and α-particles in men vs women by spectral counts, (preβ-HDL, 15661.74±789.00 vs 20298.29±1076.15, p=0.002), and (α-HDL, 50447.00± 546.52 vs 63006.35±756.81, p=0.03). Conversion of free cholesterol into cholesteryl esters by LCAT was decreased in men vs. women (12.00±8.07 %/h vs 16.44±9.11 %/h, p=0.03). We identified 108 HDL-associated proteins in a representative man and woman, of which, 15 were found only in the female sample Conclusions: Sex-specific differences in measures of HDL functionality were found in patients with severe AS. Future studies should consider whether sex-based differences in HDL functionality might account for the decreased burden of calcification in women vs. men with severe AS.

We examined clinical, biochemical and lipoprotein profiles and HDL cholesterol efflux capacity (CEC) in 155 patients undergoing CEA and compared the results with patients with an acute coronary syndrome (ACS time 0 n=26) measured within 48 hours of the event, and again at 12 weeks (ACS recovery, n=26), in patients with chronic, stable CAD (sCAD) n=27 and in healthy controls. There were 110 men (71%) and 45 women (29%) with a mean age 69±10 years in the CEA group. Mean HDL-C was 0.96±0.26 mmol/L (38±10 mg/dL). There were no significant differences in HDL-C between CEA, ACS and sCAD subjects. HDL was obtained after depletion of apo B-containing lipoproteins with PEG precipitation. Cellular efflux capacity was determined by incubating HDL in cAMP-stimulated J774 mouse peritoneal macrophages for 6 hours. Specific cholesterol efflux was obtained by subtracting total efflux from efflux in non-cAMP stimulated cells. The procedure was standardized to enable medium throughput. Coefficient of variability was approximately 5%. HDL from CEA patients differ in its ability to promote cholesterol efflux. The range of CEC observed was: min 14.7%, max 34.0% mean 22.4±0.6%; (IQR 18.9-27.3% median 22.0). We found a weak correlation between HDL-C and CEC in patients CEA (r= 0.20, P=0.012); a significant correlation was found between apo A-I and CEC (r=0.23, P=0.005). Subjects with similar HDL-C or apoA-I differed in their ability to promote cellular cholesterol efflux, suggesting that the HDL-C mass does not reflect functionality. We found similar CEC in patients with CAD and ACS recovery. Here, we report that patients with severe carotid atherosclerosis have low HDL-C and a CEC similar to that observed in CAD patients. The function of HDL to promote cellular cholesterol efflux, as determined by CEC, varied over a wide range and was only weakly correlated with HDL-C. The significant correlation between apo AI and CEC suggests that HDL particle size -and composition may also be an important determinant of the ability to promote cellular cholesterol efflux.
