Guo Q, Colasanti A, Owen DR, Onega M, Kamalakaran A, Bennacef Iet al., 2013, Quantification of the Specific Translocator Protein Signal of18F-PBR111 in Healthy Humans: A Genetic PolymorphismEffect on In Vivo Binding, Journal of Nuclear Medicine, Vol: 54, Pages: 1-9

PET is used to image active inflammatory processes by targetingthe translocator protein (TSPO). In vitro, second-generation TSPOradioligands, such as PBR111, have been shown to bind to humantissue samples with either high affinity (high-affinity binders, HABs),low affinity (low-affinity binders, LABs), or an intermediate, mixedaffinity (mixed-affinity binders, MABs). We previously explainedthese differences in affinity in human tissue via the rs6971 polymorphismin the TSPO gene and predicted that the specific signalfrom PET ligands in vivo would vary accordingly. In silico modelingpredicted that 18F-PBR111 would have a moderate to high specificto-nonspecific ratio in the normal human brain. To test these predictions,we present here the analysis and modeling of 18F-PBR111data in healthy humans. Methods: Twenty-one subjects (9 HABs, 8MABs, and 4 LABs), 28–62 y old, genotyped for the rs6971 polymorphism,underwent 120-min PET scans with arterial samplingafter a bolus injection of 18F-PBR111. Compartmental models andLogan graphical methods enabled estimation of the total volume ofdistribution (VT) in regions of interest (ROIs). To evaluate the specificsignal, we developed 2 methods to estimate the nondisplaceablevolume of distribution (VND): the first assumed that the in vitro affinityratio of 18F-PBR111 in HABs relative to LABs (4-fold) is preserved invivo; the second modeled the difference in the HAB and MAB signalsin the context of an occupancy plot. Results: A 2-tissue-compartmentmodel described the data well, and a significant differencewas found between the VT of HABs, MABs, and LABs across allROIs examined (P , 0.05). We also found a significant correlationbetween VT and age for both HABs and MABs in most ROIs. Theaverage VND estimated by the 2 methods was 1.18 6 0.35 (methodI: VND 5 0.93, method II: VND 5 1.42), implying that the 18F-PBR111BPND was 2.78 6 0.46 in HABs, 1.48 6 0.28 in MABs, and 0.51 60.17 in LABs and that the in vivo affinity ratio was simil

Preclinical imaging with magnetic resonance imaging (MRI), computerised tomography (CT), ultrasound (US), positron emission tomography (PET) or single-photon emission computed tomography (SPECT) enable non-invasive measures of tissue structure, function or metabolism in vivo. The technologies can add value to preclinical studies by enabling dynamic pharmacological observations on the same animal and because of possibilities for relatively direct clinical translation. Potential benefits from the application of preclinical imaging should be considered routinely in drug development.

UK Biobank is a prospective cohort study with 500,000 participants aged 40 to 69. Recently an enhanced imagingstudy received funding. Cardiovascular magnetic resonance (CMR) will be part of a multi-organ, multi-modalityimaging visit in 3–4 dedicated UK Biobank imaging centres that will acquire and store imaging data from 100,000participants (subject to successful piloting). In each of UK Biobank’s dedicated bespoke imaging centres, it isproposed that 15–20 participants will undergo a 2 to 3 hour visit per day, seven days a week over a period of5–6 years. The imaging modalities will include brain MRI at 3 Tesla, CMR and abdominal MRI at 1.5 Tesla, carotidultrasound and DEXA scans using carefully selected protocols. We reviewed the rationale, challenges and proposedapproaches for concise phenotyping using CMR on such a large scale. Here, we discuss the benefits of this imagingstudy and review existing and planned population based cardiovascular imaging in prospective cohort studies. Wewill evaluate the CMR protocol, feasibility, process optimisation and costs. Procedures for incidental findings, qualitycontrol and data processing and analysis are also presented. As is the case for all other data in the UK Biobankresource, this database of images and related information will be made available through UK Biobank’s AccessProcedures to researchers (irrespective of their country of origin and whether they are academic or commercial)for health-related research that is in the public interest.

Background:SRT2104 has been developed as a selective small molecule activator of SIRT1, a NAD+-dependent deacetylaseinvolved in the regulation of energy homeostasis and the modulation of various metabolic pathways, including glucosemetabolism, oxidative stress and lipid metabolism. SIRT1 has been suggested as putative therapeutic target in multiple age-related diseases including type 2 diabetes and dyslipidemias. We report the first clinical trial of SRT2104 in elderlyvolunteers.Methods:Oral doses of 0.5 or 2.0 g SRT2104 or matching placebo were administered once daily for 28 days.Pharmacokinetic samples were collected through 24 hours post-dose on days 1 and 28. Multiple pharmacodynamicendpoints were explored with oral glucose tolerance tests (OGTT), serum lipid profiles, magnetic resonance imaging (MRI)for assessment of whole body visceral and subcutaneous fat, maximal aerobic capacity test and muscle 31P magneticresonance spectroscopy (MRS) for estimation of mitochondrial oxidative capacity.Results:SRT2104 was generally safe and well tolerated. Pharmacokinetic exposure increased less than dose-proportionally.Mean Tmax was 2–4 hours with elimination half-life of 15–20 hours. Serum cholesterol, LDL levels and triglyceridesdecreased with treatment. No significant changes in OGTT responses were observed. 31P MRS showed trends for morerapid calculated adenosine diphosphate (ADP) and phosphocreatine (PCr) recoveries after exercise, consistent withincreased mitochondrial oxidative phosphorylation.Conclusions:SRT2104 can be safely administered in elderly individuals and has biological effects in humans that areconsistent with SIRT1 activation. The results of this study support further development of SRT2104 and may be useful indose selection for future clinical trials in patients.

In our contribution to this special issue focusing on advances in Alzheimer's disease (AD) research since the centennial, we will briefly review some of our own studies applying magnetic resonance imaging (MRI) measures of function and connectivity for characterization of genetic contributions to the neuropathology of AD and as candidate biomarkers. We review how functional MRI during both memory encoding and at rest is able to define APOE4 genotype-dependent physiological changes decades before potential development of AD and demonstrate changes distinct from those with healthy aging. More generally, imaging provides a powerful quantitative measure of phenotype for understanding associations arising from whole genome studies in AD. Structural connectivity measures derived from diffusion tensor MRI (DTI) methods offer additional markers of neuropathology arising from the secondary changes in axonal caliber and myelination that accompany decreased neuronal activity and neurodegeneration. We illustrate applications of DTI for more finely mapping neurodegenerative changes with AD in the thalamus in vivo and for defining neuropathological changes in the white matter itself. The latter efforts have highlighted how sensitivity to the neuropathology can be enhanced by using more specific DTI measures and interpreting them relative to knowledge of local white matter anatomy in the healthy brain. Together, our studies and related work are helping to establish the exciting potential of a new range of MRI methods as neuropathological measures and as biomarkers of disease progression. © 2013 The authors and IOS Press.
