BODIPY-based molecular probe for imaging of cerebral ?-amyloid plaques.

ABSTRACT: We designed and synthesized a BODIPY-based probe (BAP-1) for the imaging of ?-amyloid plaques in the brain. In binding experiments in vitro, BAP-1 showed excellent affinity for synthetic A? aggregates. ?-Amyloid plaques in Tg2576 mouse brain were clearly visualized with BAP-1. In addition, the labeling of ?-amyloid plaques was demonstrated in vivo in Tg2576 mice. These results suggest BAP-1 to be a useful fluorescent probe for the optical imaging of cerebral ?-amyloid plaques in patients with Alzheimer's disease.

A BODIPY-Based Fluorogenic Probe for Specific Imaging of Lipid Droplets.

Project description:We developed an easily accessible boron-dipyrromethene (BODIPY)-based fluorogenic probe, which we named LD-TB. This probe emits bright fluorescence in oil; when compared with aqueous solution, a significant enhancement of fluorescence brightness is observed. Cellular experiments confirmed that the probe stains the lipid droplets (LDs) specifically in both live and fixed cells, providing background-free images. Compared with Nile Red dye, a commonly used LD marker, LD-TB showed superior photostability. The sharp absorption and emission bands enable its multicolor imaging with blue and green probes. Importantly, the probe has proved to have low toxicity and is compatible with cell fixation. Our research provides a promising new fluorogenic probe for specific imaging of LDs.

Novel Benzofurans with (99m)Tc Complexes as Probes for Imaging Cerebral ?-Amyloid Plaques.

Project description:Two novel benzofuran derivatives coupled with (99m)Tc complexes were tested as probes for imaging cerebral ?-amyloid plaques using single photon emission tomography. Although both derivatives bound to A?(1-42) aggregates, (99m)Tc-BAT-BF showed higher affinity than (99m)Tc-MAMA-BF. In sections of brain tissue from an animal model of AD, (99m)Tc-BAT-BF clearly labeled ?-amyloid plaques. In biodistribution experiments using normal mice, (99m)Tc-BAT-BF displayed high uptake soon after its injection and washed out from the brain rapidly, a highly desirable feature for an imaging agent. (99m)Tc-BAT-BF may be a potential probe for imaging ?-amyloid plaques in Alzheimer's brains.

A quadrupolar two-photon fluorescent probe for <i>in vivo</i> imaging of amyloid-? plaques.

Project description:The formation of beta amyloid (A?) plaques in specific brain regions is one of the early pathological hallmarks of Alzheimer's disease (AD). To enable the early detection of AD and related applications, a method for real-time, clear 3D visualization of A? plaques in vivo is highly desirable. Two-photon microscopy (TPM) which utilizes two near-infrared photons is an attractive tool for such applications. However, this technique needs a sensitive and photostable two-photon (TP) probe possessing bright TP exited fluorescence to impart high signal-to-noise (S/N) visualization of A? plaques. Herein, we report a quadrupolar TP fluorescent probe (QAD1) having large TP action cross section (??max = 420 GM) and its application for in vivo TPM imaging of A? plaques. This probe, designed with a centrosymmetric D-A-D motif with a cyclic conjugating bridge and solubilizing unit, displays bright TP excited fluorescence, appreciable water solubility, robust photostability, and high sensitivity and selectivity for A? plaques. Using the real-time TPM imaging of transgenic 5XFAD mice after intravenous injection of QAD1, we show that this probe readily enters the blood brain barrier and provides high S/N ratio images of individual A? plaques in vivo. We also used QAD1 in dual-color TPM imaging for 3D visualization of A? plaques along with blood vessels and cerebral amyloid angiopathy (CAA) inside living mouse brains. These findings demonstrate that this probe will be useful in biomedical applications including early diagnosis and treatments of AD.

Multimodal Imaging of Amyloid Plaques: Fusion of the Single-Probe Mass Spectrometry Image and Fluorescence Microscopy Image.

Project description:Alzheimer's disease (AD) is one of the most common neurodegenerative diseases. The formation of amyloid plaques by aggregated amyloid beta (A?) peptides is a primary event in AD pathology. Understanding the metabolomic features and related pathways is critical for studying plaque-related pathological events (e.g., cell death and neuron dysfunction). Mass spectrometry imaging (MSI), due to its high sensitivity and ability to obtain the spatial distribution of metabolites, has been applied to AD studies. However, limited studies of metabolites in amyloid plaques have been performed due to the drawbacks of the commonly used techniques such as matrix-assisted laser desorption/ionization MSI. In the current study, we obtained high spatial resolution (?17 ?m) MS images of the AD mouse brain using the Single-probe, a microscale sampling and ionization device, coupled to a mass spectrometer under ambient conditions. The adjacent slices were used to obtain fluorescence microscopy images to locate amyloid plaques. The MS image and the fluorescence microscopy image were fused to spatially correlate histological protein hallmarks with metabolomic features. The fused images produced significantly improved spatial resolution (?5 ?m), allowing for the determination of fine structures in MS images and metabolomic biomarkers representing amyloid plaques.

A Simple BODIPY-Based Viscosity Probe for Imaging of Cellular Viscosity in Live Cells.

Project description:Intracellular viscosity is a fundamental physical parameter that indicates the functioning of cells. In this work, we developed a simple boron-dipyrromethene (BODIPY)-based probe, BTV, for cellular mitochondria viscosity imaging by coupling a simple BODIPY rotor with a mitochondria-targeting unit. The BTV exhibited a significant fluorescence intensity enhancement of more than 100-fold as the solvent viscosity increased. Also, the probe showed a direct linear relationship between the fluorescence lifetime and the media viscosity, which makes it possible to trace the change of the medium viscosity. Furthermore, it was demonstrated that BTV could achieve practical applicability in the monitoring of mitochondrial viscosity changes in live cells through fluorescence lifetime imaging microscopy (FLIM).

Multidentate (18)F-polypegylated styrylpyridines as imaging agents for A? plaques in cerebral amyloid angiopathy (CAA).

Project description:?-Amyloid plaques (A? plaques) in the brain are associated with cerebral amyloid angiopathy (CAA). Imaging agents that could target the A? plaques in the living human brain would be potentially valuable as biomarkers in patients with CAA. A new series of (18)F styrylpyridine derivatives with high molecular weights for selectively targeting A? plaques in the blood vessels of the brain but excluded from the brain parenchyma is reported. The styrylpyridine derivatives, 8a-c, display high binding affinities and specificity to A? plaques (K(i) = 2.87, 3.24, and 7.71 nM, respectively). In vitro autoradiography of [(18)F]8a shows labeling of ?-amyloid plaques associated with blood vessel walls in human brain sections of subjects with CAA and also in the tissue of AD brain sections. The results suggest that [(18)F]8a may be a useful PET imaging agent for selectively detecting A? plaques associated with cerebral vessels in the living human brain.

A Novel BODIPY Quaternary Ammonium Salt-Based Fluorescent Probe: Synthesis, Physical Properties, and Live-Cell Imaging.

Project description:The development of biological fluorescent probes is of great significance to the field of cancer bio-imaging. However, most current probes within the bulky hydrophobic group have limited application in aqueous medium and restricted imaging under physiological conditions. Herein, we proposed two efficient molecules to study their physical properties and imaging work, and the absorption and fluorescence intensity were collected with varying ions attending in aqueous medium. We enhance the water solubility through the quaternization reaction and form a balance between hydrophilic and hydrophobicity with dipyrrome-theneboron difluoride (BODIPY) fluorophore. We introduced pyridine and dimethylaminopyridine (DMAP) by quaternization and connected the BODIPY fluorophore by ethylenediamine. The final synthesized probes have achieved ideal affinity with HeLa cells (human cervical carcinoma cell line) in live-cell imaging which could be observed by Confocal Microscope. The probes also have a good affinity with subcutaneous tumor cells in mice in in vivo imaging, which may make them candidates as oncology imaging probes.

PiB-Conjugated, Metal-Based Imaging Probes: Multimodal Approaches for the Visualization of ?-Amyloid Plaques.

Project description:In an effort toward the visualization of ?-amyloid plaques by in vivo imaging techniques, we have conjugated an optimized derivative of the Pittsburgh compound B (PiB), a well-established marker of A? plaques, to DO3A-monoamide that is capable of forming stable, noncharged complexes with different trivalent metal ions including Gd(3+) for MRI and (111)In(3+) for SPECT applications. Proton relaxivity measurements evidenced binding of Gd(DO3A-PiB) to the amyloid peptide A?1-40 and to human serum albumin, resulting in a two- and four-fold relaxivity increase, respectively. Ex vivo immunohistochemical studies showed that the DO3A-PiB complexes selectively target A? plaques on Alzheimer's disease human brain tissue. Ex vivo biodistribution data obtained for the (111)In-analogue pointed to a moderate blood-brain barrier (BBB) penetration in adult male Swiss mice (without amyloid deposits) with 0.36% ID/g in the cortex at 2 min postinjection.

Differentiating Aβ40 and Aβ42 in amyloid plaques with a small molecule fluorescence probe.

Project description:Differentiating amyloid beta (Aβ) subspecies Aβ40 and Aβ42 has long been considered an impossible mission with small-molecule probes. In this report, based on recently published structures of Aβ fibrils, we designed iminocoumarin-thiazole (ICT) fluorescence probes to differentiate Aβ40 and Aβ42, among which Aβ42 has much higher neurotoxicity. We demonstrated that ICTAD-1 robustly responds to Aβ fibrils, evidenced by turn-on fluorescence intensity and red-shifting of emission peaks. Remarkably, ICTAD-1 showed different spectra towards Aβ40 and Aβ42 fibrils. In vitro results demonstrated that ICTAD-1 could be used to differentiate Aβ40/42 in solutions. Moreover, our data revealed that ICTAD-1 could be used to separate Aβ40/42 components in plaques of AD mouse brain slides. In addition, two-photon imaging suggested that ICTAD-1 was able to cross the BBB and label plaques in vivo. Interestingly, we observed that ICTAD-1 was specific toward plaques, but not cerebral amyloid angiopathy (CAA) on brain blood vessels. Given Aβ40 and Aβ42 species have significant differences of neurotoxicity, we believe that ICTAD-1 can be used as an important tool for basic studies and has the potential to provide a better diagnosis in the future.

Risk of developing cerebral ?-amyloid plaques with posttranslational modification among HIV-infected adults.

Project description:OBJECTIVES:Evidence of accelerated brain aging among HIV-infected adults argues for the increased risk of developing cerebral ?-amyloid (A?) plaques. We compared the frequency of A? plaque-bearing cases in our HIV cohort with that in a general cohort reported by Braak et al. We explored posttranslationally modified A? forms (N3pE, E22P, phospho-Ser8) in plaques and E22P-A? in the postmortem cerebrospinal fluid (CSF) in the HIV cohort. DESIGN:Clinicopathological study of HIV-infected adults. METHODS:To assess frontal A? plaque deposition, we conducted immunohistochemistry for generic A? (4G8) and three modified A? forms. We determined CSF E22P-A? levels by ELISA. RESULTS:We found 4G8-A? plaques in 29% of 279 HIV-infected cases. Within the age range of 31-70 years, the frequency of 4G8-A? plaque-bearing cases was higher in our HIV cohort (n?=?273) compared with the general cohort (n?=?1110) overall (29.3 vs. 25.8%) and across four age groups by decade (odds ratio 2.35, P?<?0.0001). In HIV-infected cases with (n?=?37) and without (n?=?12) 4G8-A? plaques, modified A? forms occurred in order: N3pE, E22P, and phospho-Ser8. In CSF assays of HIV-infected cases with (n?=?27; 17 focal, 10 widespread) and without (n?=?11) 4G8-A? plaques, the median E22P-A?/A?40 ratio was higher among cases with widespread plaques than in cases with focal or absent plaques (P?=?0.047). CONCLUSION:Our findings suggest HIV-infected adults are at increased risk of developing cerebral A? plaques. The occurrence of modified A? forms in order suggests the progression stages of A? plaque deposition. The potential for E22P-A? as a CSF biomarker of cerebral A? plaques should be investigated.
