The systematic study of nanoparticle-biological interactions requires particles to be reproducibly dispersed in relevant fluids along with further development in the identification of biologically relevant structural details at the materials-biology interface. Here, we develop a biocompatible long-term colloidally stable water dispersion of few-layered graphene nanoflakes in the biological exposure medium in which it will be studied. We also report the study of the orientation and functionality of key proteins of interest in the biolayer (corona) that are believed to mediate most of the early biological interactions...

Apolipoprotein E (ApoE) is an important lipid carrier in both the periphery and the brain. The ApoE ε4 allele (ApoE4) is the single most important genetic risk-factor for Alzheimer's disease (AD) while the ε 2 allele (ApoE2) is associated with a lower risk of AD-related neurodegeneration compared to the most common variant, ε 3 (ApoE3). ApoE genotype affects a variety of neural circuits; however, the olfactory system appears to provide early biomarkers of ApoE genotype effects. Here, we directly compared olfactory behavior and olfactory system physiology across all three ApoE genotypes in 6-month- and 12-month-old mice with targeted replacement for the human ApoE2, ApoE3, or ApoE4 genes...

The space radiation environment includes helium (⁴He) ions that may impact brain function. As little is known about the effects of exposures to ⁴He ions on the brain, we assessed the behavioral and cognitive performance of C57BL/6J × DBA2/J F1 (B6D2F1) mice three months following irradiation with ⁴He ions (250 MeV/n; linear energy transfer (LET) = 1.6 keV/μm; 0, 21, 42 or 168 cGy). Sham-irradiated mice and mice irradiated with 21 or 168 cGy showed novel object recognition, but mice irradiated with 42 cGy did not...

Apolipoprotein E knockout (apoE-KO) mice present synaptic loss, cognitive dysfunction, and high plasma lipid levels that may affect brain function simulating Alzheimer disease. Plasma and brain sterols were measured in apoE-KO and in wild type control mice on a cholesterol-free, phytosterol-containing diet by gas chromatography coupled to a mass spectrometer. Plasma cholesterol and phytosterols (campesterol and sitosterol) were higher in apoE-KO compared to control mice. Cholesterol precursors (desmosterol and lathosterol) were not detected in plasma of control mice but were present in apoE-KO mice...

BACKGROUND: It remains unknown whether Non-POU-domain-containing octamer-binding protein (NonO) plays a causative role in plaque destabilization. We hypothesized that NonO gene silencing may stabilize atherosclerotic plaque by increasing P4Hα1 expression and inhibiting the inflammation. METHODS AND RESULTS: Vulnerable atherosclerotic plaques were induced in ApoE-/- mice by high fat diet, perivascular collar placement and mental stress. Compared with normal carotid arteries, those contained vulnerable plaques had high NonO expression...

This study is to investigate the associations between apolipoprotein E (ApoE) gene polymorphisms and cardiovascular complications of uremic patients on maintenance hemodialysis (MHD). Uremic patients on MHD (189, case group) and healthy people (165, control group) were recruited. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to test ApoE gene polymorphisms. Indicators of MHD and cardiovascular complications were observed. Compared with the control group, the case group had decreased frequency of ε3/3 genotype and ε3 allele and increased ε4/3 genotype and ε4 allele...

Dementia is a significant and costly health condition that affects 5 million adults and is the fifth leading cause of death among Americans older than 65 years. The prevalence of dementia will likely increase in the future because the number of Americans older than 65 years is expected to double by 2060. Risk factors for dementia include age; family history of dementia; personal history of cardiovascular disease, cerebrovascular disease, diabetes mellitus, or midlife obesity; use of anticholinergic medications; apolipoprotein E4 genotype; and lower education level...

The quality and quantity of high-density lipoprotein (HDL) in blood plasma are important for preventing coronary artery disease. ATP-binding cassette protein A1 (ABCA1) and apolipoprotein A-I (apoA-I) play essential roles in nascent HDL formation, but controversy persists regarding the mechanism by which nascent HDL is generated. In the "direct loading model", apoA-I acquires lipids directly from ABCA1 while it is bound to the transporter. By contrast, in the "indirect model", apoA-I acquires lipids from the specific membrane domains created by ABCA1...

Vasoactive intestinal peptide (VIP) is a neuropeptide that exerts various vascular and cardioprotective functions and regulates immune function and inflammatory response at multiple levels. However, its role in inflammatory cardiovascular disorders is largely unknown. Myocarditis and atherosclerosis are two inflammatory and autoimmune cardiovascular diseases that cause important adverse circulatory events. In this study, we investigate the therapeutic effects of VIP in various well-established preclinical models of experimental autoimmune myocarditis and atherosclerosis...

BACKGROUND: Perivascular adipose tissue (PVAT) accelerates plaque progression and increases cardiovascular risk. We tested the hypothesis that PVAT contributed to plaque vulnerability and investigated whether endoplasmic reticulum stress (ER stress) in PVAT played an important role in vulnerable plaque. METHODS: We transplanted thoracic aortic PVAT or subcutaneous adipose tissue as a control, from donor mice to carotid arteries of recipient apolipoprotein E deficient (apoE-/- ) mice after removing carotid artery collar placed for 6 weeks...

OBJECTIVE:  High-density lipoprotein (HDL) has been epidemiologically shown to be associated with the outcome of sepsis. One potential mechanism is that HDL possesses pleiotropic effects, such as anti-apoptosis, some of which can be ascribed to sphingosine 1-phosphate (S1P) carried on HDL via apolipoprotein M (apoM). Therefore, the aim of this study was to elucidate the roles of apoM/S1P in the consequent lethal conditions of sepsis, such as multiple organ failure caused by severe inflammation and/or disseminated intravascular coagulation...

The greatest risk factor for developing Alzheimer's disease (AD) is aging. The major genetic risk factor for AD is the ɛ4 allele of the APOE gene, encoding the brain's major lipid transport protein, apolipoprotein E (ApoE). The research community is yet to decipher why the ApoE4 variant pre-disposes to AD, and how aging causes the disease. Studies have shown deregulated levels of sphingolipids, including decreased levels of the neuroprotective signaling lipid sphingosine 1-phosphate (S1P), and increased ceramide content, in brain tissue and serum of people with pre-clinical or very early AD...

The use of nanocarriers as drug delivery vehicles brings them into contact with blood plasma proteins. Polymeric nanocarriers require some sort of surfactant to ensure colloidal stability. Formation of the protein corona is therefore not only determined by the intrinsic properties of the nanocarrier itself, but also by the accompanying surfactant. Although it is well known that surfactants have an impact on protein structure, only few studies were conducted on the specific effect of surfactants on the composition of protein corona of nanocarriers...
