Neuroinflammation in Asymptomatic Carotid Artery Disease - Imaging Substudy

This clinical imaging substudy will use the small molecule translocator protein (TSPO) ligand, Fludeoxyglucose(18F)-labeled DPA-714, to compare neuroinflammation in individuals with high or low grade asymptomatic carotid artery stenosis (aCAD) who are participating in the separate Neuroinflammation in Asymptomatic Carotid Artery Disease study lead by Dr. Ron Lazar (IRB-300007806). The positron emission tomography (PET) tracer [18F]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation.

Neuroinflammation and Age-associated Brain Pathology: Two Potential Mechanisms of Cognitive Impairment in Ovarian Cancer

This clinical study will use the small molecule translocator protein (TSPO) ligand, 18F-labeled DPA- 714, to visualize and quantify neuroinflammation in treatment naivete women with stage 1-4 newly diagnosed ovarian cancer (without brain metastases) prior to starting neoadjuvant chemotherapy treatment (baseline) and within a month of completing first 6 cycles of cytotoxic chemotherapy treatment (follow-up). In addition, we will use the well-characterized small molecule PET(Positron Emission Tomography) tracer, 11C-labeled Pittsburgh compound B (PiB) to visualize and quantify the regional brain distribution of pathological amyloid deposition at baseline only. The brain amyloid PET and MRI data acquired through this study will be correlated with cognitive test data, clinical data, genetic testing, and biospecimens collected in this study.

NeuroFLiPP - Parametric PET of Neuroinflammation in Fatty Liver Disease

Alzheimer's Disease and related dementias (ADRD) affect about 6 million people in the U.S. and are the fifth leading cause of death for adults over 65. Recent research is investigating how chronic liver diseases like Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), which affects one-third of the U.S. population, might influence ADRD through the liver-brain axis. MASLD shares risk factors with Alzheimer's, such as diabetes and hypertension, and studies have linked MASLD to increased risks of cognitive decline and ADRD. Mouse-model studies suggest that chronic liver inflammation in MASLD can induce neuroinflammation and accelerate Alzheimer's pathology, highlighting the importance of studying the liver-brain connection to identify new therapeutic targets for ADRD.
The goal of this research is to develop a practical PET imaging method using 18F-FDG to simultaneously assess liver and brain inflammation in patients with MASLD-related ADRD. This approach leverages dynamic FDG-PET scanning and advanced tracer kinetic modeling to quantify glucose transport, overcoming limitations of traditional imaging methods that cannot noninvasively assess chronic liver inflammation. The new method aims to enable comprehensive imaging of liver-brain inflammation crosstalk, validated against the 18F-DPA-714 radiotracer. Success in this project could provide a valuable imaging tool for linking liver inflammation with neuroinflammation and cognitive decline, advancing clinical research and potentially uncovering new pathways for ADRD treatment

A mini-review: Application of the radiopharmaceutical [18F]DPA-714 in neuroinflammation research in post-SARS-CoV-2 patients

Review

作者: Boniek, Douglas ; Malamut, Carlos

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has been linked to significant neurological complications, including neuroinflammation. This mini review explores the application of the radiopharmaceutical [¹⁸F]DPA-714 in neuroinflammation studies in post-SARS-CoV-2 patients using Positron Emission Tomography - Computed Tomography (PET-CT) imaging technology. [¹⁸F]DPA-714, a specific ligand for the translocator protein (TSPO), enables precise visualization and quantification of microglial activation, a key marker of neuroinflammation. Recent studies demonstrate that post-COVID-19 patients exhibit increased uptake of [¹⁸F]DPA-714 in various brain regions, correlating with persistent symptoms such as fatigue, cognitive dysfunction, and mood alterations. The application of [¹⁸F]DPA-714 in longitudinal studies can monitor the progression of neuroinflammation and evaluate the efficacy of therapeutic interventions, allowing personalized treatment adjustments. Additionally, exploring new TSPO ligands can complement data obtained with [¹⁸F]DPA-714, offering a more comprehensive view of neuroinflammatory processes. This article discusses the technical challenges in synthesizing and applying [¹⁸F]DPA-714, including the need for standardized imaging protocols and variability in binding due to genetic polymorphisms in TSPO. As a conclusion that [¹⁸F]DPA-714 is a valuable tool for research and treatment of neuroinflammation in post-SARS-CoV-2 patients, with significant implications for the development of personalized therapies and clinical monitoring.

TSPO‐PET in pre‐surgical evaluations: Correlation of neuroinflammation and SEEG epileptogenicity mapping in drug‐resistant focal epilepsy

Article

Abstract:

Objectives:

Resective surgery in drug‐resistant focal epilepsy (DRFE) requires extensive evaluation to localize the epileptogenic zone (EZ). When non‐invasive phase 1 assessments (electroencephalography, EEG; magnetic resonance imaging, MRI; and 18F‐Fluorodeoxyglucose–positron emission tomography, [18F]FDG‐PET) are inconclusive for EZ localization, invasive investigations such as stereo‐EEG (SEEG) are necessary. Epileptogenicity maps (Ems) visualize the EZ using SEEG‐identified ictal high‐frequency oscillations (iHFOs). PET imaging with radioligands targeting the18‐kDa translocator protein (TSPO), a marker of glial activation, may aid EZ localization. This study investigates the correlation between TSPO‐PET imaging and SEEG iHFOs in DRFE to determine the utility of TSPO‐PET in pre‐surgical assessments, especially in complex or non‐lesional cases.

Methods:

Patients with DRFE and inconclusive phase 1 assessments were recruited from Bicêtre Hospital (AP‐HP) for a prospective study (Eudract 2017–003381‐27). They underwent SEEG and [18F]DPA‐714 (N,N‐diethyl‐2‐(2‐(4‐(2‐(fluoro‐18F)ethoxy)phenyl)‐5,7‐dimethylpyrazolo[1,5‐a]pyrimidin‐3‐yl)acetamide) (TSPO radioligand) PET imaging. Statistical parametric mapping (SPM) techniques analyzed significant [18F]DPA‐714‐PET uptake (TSPO‐map) and generated epileptogenicity maps (EM‐map). Correlation analyses at regional and voxel‐of‐interest (VOI) levels assessed the relationship between TSPO‐map and EM‐map.

Results:

We were able to obtain and analyze both maps in 12 of 17 patients recruited. A significant positive correlation between EM‐map and TSPO‐map in focal epilepsies was found regionally (r = .81, p < .00004) and at the VOI level (r = .79, p < .00003). Temporal, insular, parietal, and occipital regions showed particularly strong correspondence. In frontal epilepsies, TSPO‐map was more focal than EM‐map, suggesting increased specificity for SEEG planning. This study also demonstrated the benefit of the TSPO‐map in identifying multiple foci in multifocal epilepsies, with or without lesions.

Significance:

These findings suggest that neuroinflammation may be a molecular substrate of the EZ in non‐lesional focal epilepsy. Identifying the EZ inpatients with complex DRFE and inconclusive MRI/[18F]FDG‐PET imaging is essential to improve resective surgery outcomes. Combining TSPO‐PET imaging with SEEG recordings may help bridge this gap.

ABSTRACT:

Purpose:

Surgery remains the only curative option for a third of refractory epilepsy patients, though success depends on precise localization of the epileptogenic zone (EZ). This study aims to assess the clinical value of hybrid 18F‐FDG and 18F‐DPA‐714 PET/MRI for accurate localization and precise boundary delineation.

Methods:

The refractory epilepsy patients who underwent surgery at Xuanwu Hospital from November 2022 to November 2023 were retrospectively recruited. Preoperative simultaneous 18F‐FDG and 18F‐DPA‐714 PET/MRI imaging were analyzed using the asymmetry index (AI) and a 4‐point visual score, with the surgical site and pathological findings serving as the gold standard.

Results:

A total of 43 patients (mean age: 26.30 ± 8.37 years, male: 28) were included in this study. Lesion localization accuracy within the EZ was 76.7% for 18F‐FDG PET/MRI, 69.8% for 18F‐DPA‐714 PET/MRI, and 60.5% for conventional MRI (p = 0.26). In 26 MRI‐positive cases, conventional MRI accurately localized all lesions within the EZ, with three cases showing negative findings on 18F‐FDG images and six on 18F‐DPA‐714. Among 17 MRI‐negative patients, thirteen demonstrated positive results on hybrid PET/MRI. Additionally, 18F‐DPA‐714 PET/MRI proved more effective in delineating lesion boundaries. Compared to 18F‐FDG, the AI score was significantly lower (0.25 ± 0.18 vs. 0.46 ± 0.19, p < 0.001), while the visual score was higher (4.00 ± 2.00 vs. 3.00 ± 0.00, p = 0.01).

Conclusion:

18F‐DPA‐714 PET/MRI can effectively complement conventional MRI in the preoperative assessment of refractory epilepsy, with localization accuracy on par with 18F‐FDG and enhanced capability in delineating lesion boundaries.
