INTRODUCTION
The Rochester Center on “Source-Specific Health Effects of Ultrafine/Fine Particles” focuses on the fine (PM2.5) fraction which includes the ultrafine particle (UFP) fraction. Our studies build on results achieved in the first round of the PM Center program with a specific emphasis to identify health hazards of source-specific physicochemical components of fine PM (e.g., UFP; organics) in epidemiological, controlled clinical, animal, and in vitro studies. Our focus has shifted to sources and pathophysiological mechanisms by which ambient ultrafine (UF)/fine PM trigger adverse health effects in the cardiovascular system and central nervous system.
We are continuing our multidisciplinary team approach involving scientists from four different institutions, building on key findings of our earlier studies. Ou studies have found that ambient PM have significant oxidative capacity, that UFP can induce significant effects not only in the respiratory tract but more importantly affect the vascular and cardiac system and that age and underlying disease (susceptibility factors) are critical modifying factors. Furthermore, our demonstration of their efficient translocation from deposition sites in the respiratory tract to other organs such as heart and CNS provided plausible hypotheses for UFP-induced oxidative stress in those organs. This could be particularly detrimental in susceptible individuals with dysfunctional vascular endothelium as the earliest manifestation of atherosclerotic vascular disease, such as seen in type 2 diabetes. These hypotheses are tested in our present studies.
Using real-world UF and fine PM in our studies, our goal is to answer questions related to the fine PM standard such as: Is there a need for a PM0.1 standard, in addition to the fine (PM2.5) standard? If so, should the standard be expressed as particle number concentration? Does the PM2.5 24-hour standard need to be changed to a shorter time (e.g., 8 hr.) standard? And also, questions related to regulating emissions from specific sources: Which sources can be identified as emitters of toxicologically important UF/fine particles? Can specific engineering devices or modifications of technical processes be designed to lower toxicologically important components of UF/fine PM from respective sources? For example, will the new particle filter trap technology for diesel engines be effective in preventing adverse health effects?
In order to answer these questions, our studies are designed to integrate detailed physicochemical analyses of ambient PM (including hourly size distribution of particle number concentrations for volatile and non-volatile fractions of ambient aerosols, particle mass for volatile and non-volatile fractions of ambient aerosols, particle bound polycyclic aromatic hydrocarbons (PAH), black smoke, particulate nitrate, sulfate, organic and elemental carbon, total oxidative capacity) with our epidemiological, clinical and toxicological studies when evaluating effects and mechanisms. While most of these studies are performed using ambient UF/fine PM, we will also use model particles in in vitro and animal studies to address specific mechanistic questions. The composition of the model particles will be based on our findings with real-world ambient UF/fine PM and on the results of source-apportionment analyses.
Objectives/Hypotheses
The objective in this second round of our Center’s multidisciplinary research is to conduct well-coordinated studies covering several aspects of the Source—Exposure—Dose—Response paradigm. Our main focus regarding health effects are extrapulmonary organ systems, such as the vascular system, the heart and the CNS. This focus is based on epidemiological and experimental findings, including our own, of extrapulmonary PM effects and awareness of newer results related to the pathophysiology of endothelial dysfunction and thrombus formation associated with cardiac events in susceptible parts of the population. Furthermore, we are assessing the role of gene-environment interactions by adding whole genome-wide association analyses to the epidemiological approach.
Our approach involves five research cores performing specific yet highly integrated experiments by a multidisciplinary team of atmospheric scientists, chemists, epidemiologists, pulmonary, vascular and cardiac physicians and scientists, inhalation-, neuro-, cellular- and molecular- toxicologists, diabetologists, and immunologists.
The following summarizes studies of our five integrated research projects to be performed by our multidisciplinary investigator team in Research Cores 1-5.
Progress Summary:
Research Core 1: Exposure Assessment and PM Source Identification
This Core is essential to the other research cores by providing data on the physico-chemical characteristics of ambient PM for correlation with epidemiological, clinical and toxicological outcomes and samples of particulate matter for toxicological investigation. Examples of the core’s activity over the past 2.5 years are the development of a Field Deployable ROS Monitor. The Core previously developed a laboratory version of a continuous monitor for particle-bound reactive oxygen species (ROS) (Venkatachari and Hopke, 2008a). This work demonstrated that it is possible to automate the use of dichlorofluorescin (DCFH) as a non-specific indicator of the oxidative capacity of particle surfaces. To move this system into the field to permit routine monitoring of particle-bound ROS, a number of problems had to be resolved, including sensitivity, user-friendly operation, reproducibility, and stability. The result has led to changes in the ROS continuous system. Further testing of the system is in progress with the expectation that it will be deployed at the NYS DEC site in Rochester late in 2008 where it will operate for at least one year. The initial plans were to operate it for a month in each quarter, but if the improvements we have made work as they appear to, it may be possible to operate the system continuously over the entire year.
Chemical Characterization of Particle-Bound ROS is another effort to correlate observed health effects with PM reactivity. To understand the mechanisms of particle-bound ROS formation, identify its likely sources, and determine the chemical pathways that might be influenced by air quality management strategies, we have pursued the chemical characterization of the constituents in particle-bound ROS. Using the a-pinene/ozone reaction to produce ROS, several new peroxide species have been separated and identified (Venkatachari and Hopke, 2008b). However, more reactive radical species may be lost in the time it takes to get samples into the analytical instruments. Further studies of more reactive by-products are underway using spin trapping agents that can help to stabilize these species. The stabilized complexes can then be examined with high resolution electron spin resonance and liquid chromatography/mass spectrometery so that a better understanding of the nature of the particle-bound ROS will be obtained.
Research on the characterization of urban ultrafine and accumulation mode particles allows composition and size analysis in real time of single particles using aerosol time-of-flight mass spectrometry (ATOFMS) that was further improved by this Core. One objective of the research is to greatly expand the understanding of the chemical composition and impact of specific sources of ultrafine particles on human health, as determined in our epidemiological, clinical and toxicological studies. Another is to develop new sampling methods coupling ATOFMS with high volume cascade impactors such that samples will be collected that represent material primarily from well defined specific sources. These samples will permit improved characterization of the PM from specific sources as well as providing material for in vitro and in vivo testing of their toxicity in Cores 4 and 5. Also, a new method for collecting size-resolved samples of ultrafine PM from ambient air directly into an aqueous solution has been developed. This method gets around issues required with sample collection on filters, where PM species have been determined to be difficult to extract.
Core 2: Epidemiological studies on extra pulmonary effects of fresh and aged urban aerosols from different sources
The objective of the epidemiological study is to determine the effect of fine and ultrafine particles on an acute phase reaction in the blood and on its prothrombotic states. One study involves 240 participants in three panels consisting of subjects with 1) type 2 diabetes mellitus (T2DM), 2) impaired glucose tolerance (IGT) and 3) potential genetic susceptibility. Particles are measured at a central measurement site in Augsburg. In addition, for a subset of 90 individuals, personal measurements of ultrafine particles using a portable condensation particle counter (CPC) as well as of temperature, humidity and noise are undertaken. Furthermore, endothelial dysfunction as a key element of coronary vulnerability as well as cardiac function characterized by ECG measures are assessed in this subset. The main phase started on the 19th of March 2007 and will presumably be terminated at the end of 2008.
As part of the ongoing Rochester Particle Center investigation more genotyping of the AIRGENE study, a multi-center European study on the impact of air pollution on inflammatory markers, was performed. The analyses on gene-environment interactions for inflammatory responses to PM air pollution are based on an extended candidate gene approach and include also studies on the impact of green vegetables. The approach involves selection of candidate Single Nucleotide Polymorphism (SNP) on their impact on mean biomarker level and its variability.
Results so far indicate that PM10 modifies fibrinogen responses via TLR4 and TNF-a genes and that ultrafine particles modify IL-6 responses via the IL-18 gene. Furthermore, 18 risk loci for type 2 diabetes and PM exposure were identified indicating an impact on adipokine function as markers of systemic responses for developing insulin resistance, and biomarkers of beta cell function establishing a link between oxidative stress and insulin secretion. Results from these collaborative Rochester PM Center studies also indicate that green vegetable consumption might protect from air pollution effects. The ongoing study investigates the influence of genetic disposition in healthy and diabetic participants and implications for air pollution research. Such genome wide association studies revolutionize current pathomechanisms for diabetes and implicate a larger role for beta cell function, to be considered in air pollution studies.
Another panel study was designed to evaluate in a Cardiac Rehabilitation Center the influence of ambient ultrafine particle exposure on cardiac response parameters. This multidisciplinary PM Center study involves close collaborations between pulmonologists, cardiologists, atmospheric scientists, biostatisticians and the support of the Center’s Support Cores.
Seventy-five patients from an active cardiac rehabilitation program within the University of Rochester Medical Center are offered enrollment in the health effects study as they enter the Cardiac Rehabilitation program. These are patients who have had a recent coronary event such as myocardial infarction or unstable angina leading to coronary stenting. In addition to the regularly electrophysiologically monitored exercise of the rehabilitation program, subjects will undergo continuously recorded Holter ECG recordings performed and analyzed by the Cardiac Core allowing evaluation of a series of ECG parameters at rest, during exercise, and during immediate post-exercise period. Venous blood samples will be obtained once per week and analyzed by the Vascular & Inflammation Core for acute phase reactants (fibrinogen and C-reactive protein). Concurrently, ultrafine particle number and particle mass will be measured continuously at a central measuring site in downtown Rochester. In addition, one-third of the patients are asked to do personal particle count monitoring in their car to and from the rehab facility and in their homes for 48 hours using a portable nuclei counter. Levels of ambient ultrafine and fine particles will then be associated with health data from the cardiac rehabilitation panel study.
To date, 40 of the 75 patients have been enrolled. To make the ambient measurements of ultrafine particles relevant to subject exposures, we are enrolling subjects who live within 5 miles of the central monitoring site or the Cardiac Rehab Center. Ultrafine particle exposures within and outside the Cardiac Rehab Center are being monitored continuously.
In our analytical plan, we will explore the relationship between closeness of home to roadway and traffic and clinical responses to ultrafine particles in the ongoing panel study. A key strength of this study is the availability of longitudinal measurements on each subject, corresponding to their successive visits to the rehabilitation center. In view of the complex relationship between UFP levels and weather (which may independently influence cardiac responses) it will be necessary to examine multivariable models including effects of variations in temperature and relative humidity as well as calendar (e.g. day of week) effects. The functional forms of the potential confounding effects will be explored using penalized spline methodology.
Core 3: Human Clinical Studies of Concentrated Ambient Ultrafine and Fine
Particles
These studies complement our epidemiological studies by focusing on type 2 diabetes as one of several susceptibility factors. The clinical studies in healthy humans and susceptible individuals with diabetes proposed in this research core focus on the effects of ambient ultrafine and fine particles on three major determinants of adverse cardiac events: 1) blood coagulation induced by effects on platelets and circulating microparticles; 2) cardiac output; and 3) cardiac rhythm and repolarization. We have initiated human clinical exposures to concentrated ambient ultrafine particles, using the Harvard concentrator and the human exposure chamber that was constructed at Rochester. Designing these studies and installation and maintenance of the concentrator and exposure system requires close collaboration with Dr. Oberdörster, Research Core #1, and the Aerosol Generation & Analysis Core among PM Center investigators and with Center Support Cores. We have now completed a clinical study of healthy never-smoking subjects inhaling concentrated ambient UFP using the concentrator.
Preliminary findings suggest UFP exposure resulted in small increases in diastolic and mean blood pressure immediately after exposure, without changes in heart rate. There were small reductions in the FEV1 and mid-expiratory flow rates after UFP exposure relative to air. Flow cytometry analyses, measurement of markers of endothelial and vascular effects, and ECG analyses are underway.
Before exposing subjects with diabetes to ambient concentrated ultrafine particles, we have completed a study of the effects of inhalation of laboratory-generated ultrafine carbon particles in subjects with diabetes. Type 2 diabetics, age 30-60, without clinical cardiovascular disease and not on “statin” medications, were exposed to filtered air or 50 µg/m3 carbon UFP (count median diameter ~30 nm, GSD 1.8) by mouthpiece for two hours, in a randomized double-blind cross-over study. Exposures were separated by at least two weeks. Nineteen subjects completed the study.
Compared with air exposure, UFP exposure increased platelet expression of CD40 ligand (CD40L), a marker of platelet activation and a key molecule in the development of atherosclerosis. UFP exposure also increased platelet-associated tissue factor (TF) and increased the number of microparticles expressing TF.
Analysis of continuous ECG recordings suggests delayed effects of UFP exposure on heart rate. We concluded that inhalation of carbon UFP for 2 hours may transiently activate vascular endothelium and/or platelets in subjects with type 2 diabetes. This finding supports the hypothesis that exposure to ambient UFP may increase the potential for vascular thrombosis in patients with severe vascular disease or ulcerated atherosclerotic plaques.
Analogous to our epidemiological studies, we plan to include also genetic analyses in our next studies involving exposure of diabetic subjects to concentrated ambient ultrafine particles.
Research Core 4: Animal Models: Cardiovascular Disease, CNS Injury and Ultrafine Particle Biokinetics
The animal studies are designed to be complementary to the epidemiological and clinical studies and further test hypotheses derived from those studies, but also to explore novel areas of PM research such as effects on the brain, on the developing organism, or the impact of using cleaner fuel on diesel exhaust-induced health effects. Thus, response measurements take into account endpoints determined in the epidemiological (Core 2) and clinical (Core 3) studies and coordinate mechanistic evaluations with Core 5 in vitro studies. In addition, effects on the CNS will also be assessed.
Much of our recent studies have been done using JCR rats, a model of type II diabetes. Although these rats are not hyperglycemic, the JCR cp/cp rats are obese, hyperlipidemic, hyperinsulinemic, and have atherosclerotic and ischemic lesions that are hallmark features of human type II diabetes. We have completed two studies with the JCR rats, one in which they were exposed to freshly-generated exhaust emission aerosols (two fuel types) in a mobile laboratory and another where the rats were exposed to concentrated ambient UFP-containing aerosols using the Harvard ultrafine particle concentrator (HUCAPS). Endpoints related to lung inflammation, inflammatory cell activation, acute phase responses, and platelet activation were measured after exposure. Groups of rats were also implanted with radiotransmitters to continuously monitor changes in heart rate, blood pressure, temperature, and activity associated with exposure to exhaust emissions or clean, filtered air.
For most of the lavage fluid and blood serum inflammatory markers, the obese insulin-resistant cp/cp rats had higher levels than in the lean rats. We also observed a slight decrease in the number of circulating platelet microparticles in obese rats that were exposed to either the concentrated ambient ultrafine particles or exhaust emission aerosols. Finally, samples obtained from the concentrator study revealed that the JCR cp/cp rats are iron overloaded and that HUCAPS exposure exacerbates this. The specific implications of this iron overloaded state in JCR cp/cp rats in terms of responses to low-level ambient UFP exposure are not yet clear. We also found a significant divergence in heart rate following on-road exposures between the air- and full exhaust-exposed rats that increased over time in the post-exposure period. This data, as well as that from JCR rats exposed to concentrated ultrafine particle-containing atmospheres, is currently being analyzed further.
Our previous studies have demonstrated that inhaled poorly-soluble laboratory-generated UFP travel to the brain and that they cause oxidative stress and inflammation in those regions where particles accumulate. Recent population-based studies have suggested a link between environmental exposures and the onset of symptoms in neurodegenerative diseases. We have, therefore, hypothesized that ambient UFP are causally related to these effects due to their ability to accumulate in the brain and to induce oxidative stress. We tested this hypothesis using a mouse model (transgenic R6/2) of early-onset neurodegeneration (in this case Huntington’s disease, HD). We exposed the R6/2 mice, starting at 5-7 days of age, to concentrated ambient UFP for 4 hrs/day, 5 days/week, for a total of 6 weeks in whole-body exposure chambers. About 1 week after the mouse pups were weaned, and then every week thereafter, locomotor function was evaluated. Statistical analyses revealed that, unlike nontransgenic mice, the locomotor performance of the transgenic mice declined over time. Serial coronal sections of brain tissue are now being evaluated for striatal atrophy and huntingtin protein (Htt) expression and aggregation. Other tissues have also been saved so that we can examine Htt aggregation as a result of exposure in other tissues (e.g. lung, heart, pancreas). These first results are encouraging, and additional studies with this and other mouse models of neurodegeneration are planned to study the potential impact of exposure to ambient PM.
Research Core 5: Ultrafine Particle Cell Interactions In Vitro: Molecular Mechanisms Leading to Altered Gene Expression in Relation to Particle Composition
Experiments in this core are intended to provide a mechanistic link and biological plausibility for the whole animal and controlled clinical (human) exposures, described in the other programs of this Particle Center. Our ability to use defined populations of cells and well characterized particles allow us to test specific hypothesis that arise from the in vivo studies described elsewhere. A particular focus of the in vitro studies is to attempt to identify mechanisms that may be involved in the enhanced susceptibility of cells from diabetics. Also by working with our particle characterization and analytical cores we will attempt to correlate cellular effects with composition that is related to specific sources.
A major thrust of the current research of this PM Center is to investigate the proposed increased sensitivity of diabetics to the effects of PM. Our in vitro studies are designed to model this under controlled conditions. As we reported previously, one of the hallmarks of the diabetic is the increased blood glucose and we have shown that culture of vascular endothelial cells in high glucose alters both the basal and particle induced cytokine responses. Using this model we have begun to address the response of pulmonary cells to particles collected by a high volume sampler in Rochester. These would be similar to PM used in animal and human clinical studies carried out using the Harvard ultrafine particle concentrator. Human respiratory epithelial cells exposed to collected ultrafine particles respond through increased production of IL-6. In contrast to previous work that focussed only on the production of NO and endothelium epithelial cells maintained under conditions of hypergycemia actually produce increased amounts of IL-6. This is in contrast to results where HUVEC were cultured under similar conditions. It is also evident that the ambient samples show a somewhat different response in these cells for this marker. In collaboration with our Analysis core we will attempt to determine if differences in compostion can help explain the differences in activity.
One question raised in our proposed studies is the role of PM induced oxidative stress in the generation of cytokine or NO ( Nitric Oxide) responses. The human clinical studies have been measuring vascular reactivity as a measure of response to inhaled PM. Included in that battery of outcomes was IL-6 and plasma Nitric Oxide (NO). To examine this response in a mechanistic manner we measured changes in both of these outcomes in cells that have had their antioxidant status altered by culturing with exogenous antioxidants.
We plan to continue to characterize the response of the microvascular endothelium to particles and begin to model for the effects of diabetes on these responses, including cells of neuronal origin and possibly cardiac muscle. Measurement of prostaglandin production, and COX-2 activation will be evaluated with respect to its usefulness as a marker.
In support of in vivo projects, we will evaluate in vitro effects of particles of differing composition originating from specific sources as collected by Core 1 in different parts of the country and followed by careful characterization of their physico-chemcial and ROS-inducing properties. The goal is to correlate source specific properties with biological effects and elucidate underlying mechanisms.
Future Activities:
Figure 1 depicts how the five Research Cores of the Rochester PM Center interact with each other with respect to (i) parallel epidemiological, clinical, animal and in vitro studies with a common focus on cardiovascular health effects and underlying mechanisms, and (ii) sequential studies starting with in vitro investigations of the biological/toxicological activity of fine PM from different sources followed by selection of the most potent PM for subsequent in vivo studies when administered to rats. Results of the in vivo and in vitro studies combined with results of detailed physicochemical analysis of the UF/fine PM from different sources will be used for correlating source specific and/or chemical specific adverse effects and toxicity. Our integrated multidisciplinary approach is designed to explore the Source—Exposure—Dose—Response paradigm with the ultimate goal to correlate adverse pulmonary, vascular, cardiac and CNS effects of airborne fine/ultrafine PM and to uncover the mechanisms which cause these effects. This interactive multidisciplinary team approach – made possible through a Center grant – proved to be very successful and resulted in many novel study designs and findings as evidenced by our publications. These achievements would have been less likely with several smaller individual grants.
