Introduction
The Rochester Center on “Source-Specific Health Effects of Ultrafine/Fine Particles” focuses on characterization of ambient PM2.5 and PM0.1 and evaluation of their effects based on epidemiological, controlled clinical as well as animal and in vitro studies. Center investigators evaluate effects and underlying pathophysiological mechanisms by which ambient ultrafine (UF)/fine PM trigger adverse health effects in the cardiovascular and central nervous systems. Our earlier findings of translocation of UFPs from deposition sites in the respiratory tract to other organs via blood circulation and via neurons to the central nervous system (CNS) provide plausible hypotheses for UFP-induced oxidative stress in those organs. Our studies are designed to integrate detailed physicochemical analyses of ambient PM with our epidemiological, clinical and toxicological studies when evaluating effects and mechanisms.
The Rochester PM Center consists of five Research Cores performing Core-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, and immunologists.
The objectives of the projects under these five integrated Research Cores that were conducted in the past project period by this multidisciplinary investigator team are provided below.
Core 1: Exposure Assessment and PM Source Identification
Objective of Research: Characterize the nature of the particle-bound reactive oxygen species (ROS) resulting from major biogenic VOC reactions with ozone.
Core 2: Epidemiological Studies on Extra Pulmonary Effects of Fresh and Aged Urban Aerosols from Different Sources.
Objective: The objective of the epidemiological study is to examine the effect of fine and ultrafine particles on systemic responses, endothelial and cardiac function. The study was conducted in Augsburg, Germany, between March 19, 2007, and December 17, 2008.
Core 3: Human Clinical Studies of Concentrated Ambient Ultrafine and Fine Particles
Objective: The overall objective of our current and planned studies is to determine the pulmonary and cardiovascular effects of exposure to ultrafine and fine particulate matter (PM).
Core 4: Animal Models: Cardiovascular Disease, CNS Injury and Ultrafine Particle Biokinetics.
The objectives of four projects performed in this reporting period are:
Objective 1: Determine CNS effects of exposure to concentrated ambient ultrafine particles in a sensitive triple-transgenic Alzheimer Disease mouse model (3xTgAD).
Objective 2a: Determine effects of early life exposure to ambient ultrafine particles of rats on the CNS.
Objective 2b: Are ambient ultrafine particles a risk factor for Parkinson’s Disease?
Objective 3: Determine effects of early life exposure to ambient ultrafine particles and ozone mixtures on the early and late pulmonary responses of mice re-challenged with ovalbumina.
Objective 4: Compare the usefulness of different modes of dosing the respiratory tract with PM, specifically ultrafine PM, to assess their inflammation potential.
Core 5: Ultrafine Particle Cell Interactions In Vitro: Molecular Mechanisms Leading to Altered Gene Expression in Relation to Particle Composition
Objective: To address specific mechanistic hypotheses, specifically related to oxidative stress induction, regarding the interactions between inhaled ultrafine particles and specific pulmonary cell populations.
Progress Summary:
Core 1: Exposure Assessment and PM Source Identification
Results: The reactions of ozone with monoterpenes was found to proceed via the formation of multiple oxygen- and carbon-centered free radical species. These radical species are highly reactive and thus, have generally not been measureable. Radical-addition reactions, also called spin trapping techniques has been applied to products from the α-pinene/ozone reaction. The detection and identification of radicals with molecular weights 199, 183, 153, and 167 Da supported previously identified mechanisms and structures.
In other studies of the formation of secondary organic aerosol in indoor air through the ozonolysis of reactive terpenes that are components of household cleaning products, we examined the formation rates of particles and particle-bound ROS at low NOx concentrations. We currently are continuing these studies at realistic NOx concentrations added to the ozone and terpene to explore the role of nitrate radicals in particle and ROS formation.
At the suggestion of the Center’s Science Advisory Committee, we have examined the ROS associated with main and side stream tobacco smoke. For mainstream smoke from regular and light cigarettes, the total quantities of ROS were 120-150 nmol and 90-110 nmol, respectively. For sidestream smoke, the values were 60-90 nmol and 30-70 nmol for regular and light cigarettes, respectively. The goal is to express ambient ROS activity with cigarette smoke equivalents.
With the data from this study, we can estimate the length of human exposure to ambient air that is equivalent to smoking or being exposed to the sidestream smoke of a Marlboro (red) cigarette. Thus, if one were to continuously breathe ambient air for a total of 2 to 3 days, the resulting ROS exposure would be equivalent to smoking one Marlboro (red) cigarette. Air heavily impacted by traffic is more polluted, and one day of continuous ambient air exposure is equivalent to smoking one cigarette.
Core 2: Epidemiological Studies on Extra Pulmonary Effects of Fresh and Aged Urban Aerosols from Different Sources.
Results: Results showed clear increases in C-reactive protein (CRP) and myeloperoxidase (MPO) in association with air pollutants for the panel of genetically susceptible individuals, confirming the hypothesis that oxidative stress plays a role in the mechanism linking air pollution and cardiovascular disease.
In addition, there was an immediate decrease in sCD40Ligand and PAI-1. These results point towards the coagulatory system. However, results are not quite conclusive as sCD40L promotes thrombus formation while PAI-1 inhibits fibrinolysis. Both markers showed a decrease for the same time lag.
Diabetics and IGT (impaired glucose tolerance) subjects had substantially reduced effects for the blood markers compared to the panel of genetically susceptibles. Therefore, one can assume that there are different mechanisms involved in those two groups. This might either be due to the underlying disease, the medication intake or both. Moreover, separate analyses showed that the associations were mostly driven by the panel of people with impaired glucose tolerance, which consists of patients with the same underlying disease, yet without the heavy medication. This confirms our initial hypothesis that medication can blunt the small associations seen between air pollution and markers for cardiovascular diseases.
Effects were mostly seen for PM2.5 and less for UFP, and most clearly for inflammatory markers. We assume that the reason for this is the inflammatory potential of particulate mass, which possibly derives from secondary organic aerosols.
In an add-on study, effects of personally measured ultrafine particles (portable condensation particle counter) and ambient air pollution on heart rate (HR) and heart rate variability (HRV) parameters in diseased individuals (with T2DM and IGT) were examined.
In previous analyses, we observed effects of 5-minute averages of personally measured ultrafine particle number concentration (PNC) on 5-minute intervals of heart rate (HR) as well as standard deviation of normal-to-normal intervals (SDNN) in 32 participants with T2DM and 32 participants with IGT. In particular, we detected a concurrent -0.56% (-1.02;-0.09%) decrease in SDNN in association with an increase of 16,000 personal PNC particles/cm³. Furthermore, an interquartile range (IQR) (12.3 µg/m³) increase in 1h-averages of ambient PM2.5 led to a -3.38% decrease in 1h-intervals of SDNN. We conducted several sensitivity analyses in order to test the robustness of these findings.
Effects of personal PNC on SDNN did not change when excluding participants taking statins or additionally adjusting for ambient 1h-averages of PM2.5. We observed slightly weaker PNC effects when excluding participants with an intake of beta-blockers or visits with cooking. However, PNC effects were stronger in participants who were not exposed to environmental tobacco smoke or when adjusting for personally measured 5 min-averages of noise exposure. The sensitivity analyses also showed only slight changes in PM2.5 effects on SDNN.
A third objective was to measure immediate ozone effects on heart rate and repolarization parameters. Associations between 1h-averages of ozone and heart rate (HR), Bazett-corrected QT-interval (QTc), T-wave amplitude (Tamp) and T-wave complexity (Tcomp) in 64 individuals with T2D or IGT and in 46 healthy individuals with a potential genetic predisposition were investigated.
We observed very short-term increases in HR, T-wave flattening and an increased T-wave complexity in association with increments in ozone. These associations were stronger in individuals with diabetes or a pre-state of diabetes. Changes in repolarization might contribute to the underlying pathophysiological changes associated with the link between elevated ozone levels and reported adverse cardiovascular outcomes such as myocardial infarctions and mortality.
A separate project on Ultrafine Particles and Cardiac Responses was performed in the Rochester Cardiac Rehabilitation Center. The objectives of the study were to assess the effects of ambient UFP exposure on biomarkers of pathophysiologic mechanisms thought to underlie previous reports of PM-mediated cardiovascular morbidity, in a panel of patients with coronary artery disease. These were patients who have had a recent coronary event such as myocardial infarction or unstable angina leading to coronary stenting.
Association between air pollution and pre-exercise holter ECG recordings were analyzed. Changes in each outcome associated with IQR increases in UFP, AMP, and PM2.5 concentration in the previous five 24-hour lag periods, as well as in the previous six showed that there was no clear pattern of response to any pollutant for MeanNN or SDNN in the pre-exercise resting period. However, there was a significant (p<0.05) 2.67 ms increase in SDNN associated with each IQR increase in PM2.5 72-95 hours before the clinic visit. Also, IQR increases in AMP accumulation mode particles in both the previous 6 and 24 hours were associated with significant 3.65 and 4.33 ms decreases in rMSSD, respectively. Although not statistically significant, decreases in rMSSD also were associated with UFP and PM2.5 at the same lag times. Although there was no pattern of QTc duration response to any pollutant, each IQR increase in AMP was associated with 0.78 ms and 1.05 ms increases in TpTe in the previous 24 hours and 24-47 hours, respectively, before the clinic session.
There were statistically significant 0.89 and 0.94 mmHg increases in systolic blood pressure (SBP) associated with IQR increases in UFP lagged 24-47 hours and PM2.5 lagged 0-5 hours, respectively, but little change in diastolic blood pressure (DBP). However, each IQR increase in UFP lagged 96-119 hours was associated with significantly decreased DBP.
White blood cell counts did not respond to any lagged pollutant concentration, but IQR increases in UFP, AMP, and PM2.5 concentrations were associated with increases in CRP and fibrinogen at most lags, although not all were statistically significant. Each IQR increase in PM2.5 was associated with a significant 0.069 mg/L increase in CRP lagged 72-95 hours, while each IQR increase in AMP lagged 24-47 hours was associated with a significant 0.120 g/L increase in fibrinogen. Similar significant increases in fibrinogen were associated with IQR increases in UFP and PM2.5 concentrations at the same lag time.
Our findings of increased TpTe associated with AMP lagged 24-47 hours, decreased HRT associated with increased AMP lagged 72-95 hours, and increased fibrinogen associated with increased AMP lagged 24-47 hours, all appeared independent of other pollutants at the same lag times, as there were only small changes in the AMP effect estimates when controlling for either UFP or PM2.5. In contrast, any change in these biomarkers associated with lagged UFP or PM2.5 was reduced or removed altogether when controlling for AMP. Similarly, the decreased rMSSD associated with UFP in the previous 5 hours and the increased SBP associated with increased PM2.5 lagged 0-5 hours both appeared independent of AMP, as the UFP/PM2.5 effect estimates were little changed from the single pollutant model to the two pollutant model including AMP.
The distribution of perceived exertion across 1,489 subject visits showed that there was no clear association between air pollution and this exertion score. The largest effect was a non-significant 0.05 decrease in perceived exertion score (95% CI = -0.12, 0.02) associated with each IQR increase in UFP lagged 48-71 hours.
Core 3: Human Clinical Studies of Concentrated Ambient Ultrafine and Fine Particles
Results: The clinical studies in healthy humans and susceptible individuals performed 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 hypothesize that the acute vascular effects of UFP exposure observed in our previous studies are a consequence of reduced NO bioavailability. We have developed a new approach to test this hypothesis, that exposure to ultrafine particles will deliver a burden of ROS to the pulmonary vascular endothelium, altering the delivery of NO, specifically as nitrite, to the systemic vasculature.
Preliminary findings showed that exposure to concentrated UFP did not cause symptoms or changes in heart rate or blood pressure. Arterial punctures were well tolerated, and no subject withdrew from the study because of discomfort. The arterial-venous gradient for nitrite increased 3 hours after UFP relative to air exposure (air, 13.96 vs. UFP, 190.39 nm, p=0.06 by paired t-test), driven by an increase in arterial nitrite concentrations after UFP but not air exposure. There were no significant effects on the reactive hyperemia index. Thus, exposure to UFP non-significantly increased nitrite arterial-venous gradients 3 hours after exposure, without effects on vascular function.
We now have completed subject exposures for this study, and analysis of all data is in progress.
Core 4: Animal Models: Cardiovascular Disease, CNS Injury and Ultrafine Particle Biokinetics
Objective 1: Results: Earlier studies in which 3xTg-AD mice were exposed for 12 days to ultrafine Mn oxide particles to examine progression of AD pathology showed that increased microglia and astrocyte activation in the hippocampus, compared to filtered air-exposed controls, was still found 2 months post-exposure. In a follow-up pilot study, four different genotypes of transgenic mice were exposed to concentrated ambient ultrafine particles for 8 days, 4 h/day. The four genotypes included: non-transgenic (non-Tg), 3xTg-AD, TNFRI/II KO (knocked out TNF I and II receptors), and 3xTg-ADxTNFRI/II KO. Analyses of hippocampal sections at 2 months post-exposure showed that overall immunostaining for a microglial marker (Iba-1) was lower in TNFRI/II KO and 3xTg-ADxTNFRI/II KO mice as compared to non-Tg and 3xTg-AD mice. When the immunostaining was evaluated on a cell-by-cell basis, it was found that there were fewer activated and more resting microglia in mice that lacked TNF receptors. Because air-exposed controls were not available for comparisons, it is not possible to make final conclusions about the impact of HUCAP exposure, which will be the goal of future studies.
Objective 2a: Results: The hypothesis that UFP may adversely influence the brain, particularly early in development, a period of brain vulnerability was tested in male and female C57BL6 mice exposed to concentrated ultrafine ambient particles at postnatal days (PN) 4-13, with a subset also re-exposed as adults (Ad) at 56-60 days of age (PN + Ad). Analyses of changes in blood corticosterone levels, behavioral studies including learning ability and locomotor activity as well as altered GFAP levels in specific brain regions indicate that ambient ultrafine particles can produce, differentially by gender, persistent behavioral, CNS and HPA (hypothalamic-pituitary-adrenal) dysfunction, even following PN only exposure. Given that such exposures are persistent and possibly life-long, these results also support the hypothesis of the potential for particulate air pollution to be a risk factor for neurodevelopmental and/or neurodegenerative disorders.
Objective 2b: Results: Ultrafine particles may translocate from deposition sites on the nasal olfactory mucosa to the CNS. The hypothesis was tested that early life postnatal exposure to concentrated ambient ultrafine particles would sensitize the CNS to subsequent adult challenge with paraquat + maneb (PQ+MB), a well-established pesticide-based model of the Parkinson’s disease phenotype (PDP). Mice exposed postnatally to concentrated ambient ultrafine particles were significantly more sensitive to the locomotor-reducing effects of PQ+MB than sham controls, or those exposed to UFP alone or PQ+MB alone. UFP and PQ+MB significantly altered catecholamine levels in both the nigrostriatal and mesocortical dopamine pathways. UFP had a particular influence on striatum, increasing NE, DOPAC, and DA turnover (DOPAC/DA) levels, while PQ+MB generally impacted midbrain, decreasing 5HT, DOPAC and dopamine turnover. An interaction between UFP and PQ+MB on cortical 5-HT levels was evidenced as a significant 5-HT decrease in PQ+MB treated animals compared to both sham controls and UFP +PQ+MB treated mice. Cortical DA also was increased in PQ+MB treated animals. This and additional findings of effects on dopamine pathways and 5-HT levels indicate that early life UFP enhances locomotor reduction in response to PQ+MB challenge and changes striatal catecholamines (DAergic cell terminals), a region critical to PD, while PQ+MB in the same animals produces catecholamine changes in the ventral midbrain (DAergic cell bodies). Conceivably, this concurrent damage to striatum and midbrain could increase nigral cell death and thereby contribute to a PDP; future analyses will include assessment of TH immunoreactivity and stereological analysis of DAergic cell counts in the SNpc and VTA.
Objective 3: Results: Early life exposures may contribute to diseases, either during childhood or later in life. We hypothesized that early life exposure to ambient ultrafine particles alters lung response and structural development leading to increased sensitivity to low level environmental challenges as adults.
Balb C and NRF 2-/- mice were exposed to concentrated ambient particles (CAPS) and 0.3 ppm ozone mixture or vehicle (filtered air) from postnatal days 4-7 and 10-13 for 4 hours/day between 0800 and 1200 hr. Mice received re-exposure starting at either postnatal day 28 or 56. At this time point mice were vehicle exposed or sensitized to either ova or ova + LPS for 3 days. Mice then were allowed to recover for 10 days after which they were challenged with vehicle, ova or ova + LPS for an additional 3 days. Mice were allowed to recover for 48 hours and then were examined. Analysis of results is ongoing. Endpoints to be examined will be lavage analysis, airway hyper-reactivity, and cytokine measurements from whole lung homogenates.
A parallel study of the same design in C57Bl6 mice has been performed. Mice received adult re-exposure starting at 8 or 26 weeks post birth for an additional 4 days creating four exposure groups as follows: postnatal air/adult air, postnatal CAPS/adult CAPS, postnatal 0.3 ppm ozone /adult 0.3 ppm ozone, postnatal CAPS + ozone/adult CAPS + ozone. A second group of mice will be exposed to influenza virus at the 26 week time point creating four exposure groups as follows: postnatal CAPS + ozone /adult influenza, postnatal CAPS/adult influenza, postnatal 0.3 ppm/adult influenza, postnatal air/adult influenza.
Initial exposures and 8-week post-birth exposures have occurred and analysis is ongoing. Twenty-six-week exposures and analysis will begin in December of this year. Endpoints to be examined will be cytokine and antioxidant mRNA analysis and lavage analysis. Histologic staining for surfactant and cytokines also will be done. Final results will be reported next year.
Objective 4: Results: Dosing the respiratory tract of laboratory rodents can be done by bolus-type delivery (intratracheal instillation, oro-pharyngeal aspiration or by inhalation). We tested the hypothesis that bolus-type delivery induces a significant acute inflammatory response in the lung, which does not occur after inhalation exposure. To test this hypothesis, we performed a proof-of-principle study and used ultrafine TiO2 particles (~25 nm primary particle size) as surrogate particles. We deposited 200 µg in the lower respiratory tract of rats either by intratracheal instillation or by 4-hr and 4-day whole-body inhalation.
The resulting inflammatory response 24 hrs post-exposure showed significant differences as determined by the appearance of neutrophils in the lung lavage fluid: 31% and 24% after 200 µg TiO2 instillation in saline and in DPPC/albumin, respectively, and only 6% after a 4-hr inhalation, and no significant inflammation after a 4-day inhalation (~200 µg deposited) of ultrafine TiO2.
These results suggest that results from bolus-type delivery of material to the respiratory tract have to be interpreted with caution. In particular, high dose rate induced mechanisms are not operating in real-world inhalation exposures. While results from bolus type administration of PM probably are still useful for toxicity ranking, provided a wide range of doses is tested, they cannot be used for quantitative risk assessment.
Core 5: Ultrafine Particle Cell Interactions In Vitro: Molecular Mechanisms Leading to Altered Gene Expression in Relation to Particle Composition
Results: During the past year we have focused on developing approaches that could be used to measure cellular responses to collected and fractionated sample of ambient ultrafine PM. Our strategy has been to use samples obtained from various sources using a novel growth tube device that would increase the yield of material available for testing. Each sample was adjusted to the same final concentration and evaluated in our indicator A549 cell line. Physical and chemical ambient measurements of the samples collected between the ports of Long Beach and Los Angeles showed that the major sources of the particles were marine diesel combustion, local diesel pollution, nearby freeway pollution, biomass burning, and transport of pollution from California’s Central Valley. The results indicate that ambient aerosol containing ultrafine PM from marine diesel engines is significantly more reactive inducing oxidative stress than ultrafine TiO2 particles. Further analyses establishing dose-response curve need to be performed.
Difficulties the Center Has Encountered:
We had difficulties with breeding sufficient numbers of newborn mice to start planned exposures with ambient concentrated ultrafine particles for evaluating pulmonary responses at a young age, and we had to start over with a new breeder pair. We are also still experiencing problems with collecting source-specific ambient ultrafine particles using a new growth tube/impinger system for studying potential responses in vitro. A larger model of the growth tube has been developed to be used for collecting source-specific ultrafine particles. In our epidemiological cohort studies, we are still finalizing the proposed genetic analyses and completion of statistical analysis for publication of these studies. Similarly, the final analysis of the large data set of the Rochester Rehab Study in patients with recent coronary events now is performed.
