Dual-channel pulse-dye densitometry can enable correction of fluorescent targeted and control agent plasma input function differences for quantitative paired-agent molecular imaging: a simulation study. JOURNAL OF BIOMEDICAL OPTICS 2025; 30:046001. [PMID: 40161250 PMCID: PMC11954597 DOI: 10.1117/1.jbo.30.4.046001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/27/2024] [Revised: 03/08/2025] [Accepted: 03/10/2025] [Indexed: 04/02/2025]
Abstract
Significance Paired-agent fluorescent molecular imaging approaches involve co-administration of a control (untargeted) imaging agent with a molecularly targeted agent to account for non-specific effects and quantify binding potential (BP)-a parameter proportional to the concentration of the targeted biomolecule. Accurate BP estimation often requires correction for differences in targeted and control agent plasma input functions (PIFs). Aim We provide a simulation-based evaluation of whether dual-channel pulse dye densitometry (PDD) can be used to measure the PIFs of co-administered targeted and control imaging agents, to enable accurate BP estimation. Approach Monte-Carlo simulations of light propagation were carried out using the anatomy and optical properties of a finger, as well as experimentally measured PIFs of co-administered anti-epidermal growth factor receptor fluorescent affibody, ABY-029, and IRDye 680LT, a control imaging agent from past mouse experiments. The accuracy of PIF shape estimation from PDD and PIF difference correction was evaluated by assessing BP estimation accuracy in a simulated "tumor" tissue. Results "Tumor" BP measurements using deconvolution correction with noise-free PIFs versus PDD-measured PIFs were compared. The relative error in PDD PIF deconvolution BP estimation was 2 ± 1 % . No statistical difference was found between the estimated BP via deconvolution correction with true PIFs and the estimated BP via the reconstructed PIFs using the proposed PAF-PDD methodology. Conclusions These results highlight the potential for developing a PDD instrument that can directly measure targeted and control agent PIFs and be used to correct for any PIF differences between agents for more quantitative estimates of BP in paired-agent imaging studies.

Image-Guided Monitoring of Mitochondria and Blood-Brain Barrier Dysfunction in Amyotrophic Lateral Sclerosis Mice. Biomater Res 2025; 29:0162. [PMID: 40099231 PMCID: PMC11912748 DOI: 10.34133/bmr.0162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 01/24/2025] [Accepted: 02/15/2025] [Indexed: 03/19/2025] Open
Abstract
Early detection of amyotrophic lateral sclerosis (ALS) progression is critical for improving disease management and therapeutic outcomes. However, the clinical heterogeneity and variability in ALS symptoms often lead to delayed diagnosis and suboptimal therapeutic interventions. Since mitochondrial dysfunction is a hallmark of ALS, we hypothesized that monitoring mitochondrial function could serve as a reliable strategy for early diagnosis and therapeutic monitoring of ALS. To address this, we synthesized and characterized 2 novel near-infrared fluorophores, ALS04 and ALS05, designed to target mitochondria and lysosomes. Their physicochemical properties, serum protein binding, fluorescence characteristics, photostability, and pharmacokinetics were systematically evaluated. We found that benzothiazole-based fluorophores exhibit excellent mitochondrial targeting, optimal optical properties, biocompatibility, and favorable biodistribution in vivo. Interestingly, ALS04 showed superior mitochondrial accumulation compared to ALS05, despite their similar physicochemical properties. This enhanced accumulation can be attributed to the lower molecular weight and higher lipophilicity of ALS04. Real-time fluorescence imaging revealed a substantial reduction in ALS04 signals in mitochondrial-rich tissues such as brown fat, highlighting its potential for monitoring mitochondrial dysfunction in early-stage ALS. Furthermore, the detection of ALS04 in the mouse brain suggests its ability to monitor blood-brain barrier hyperpermeability, another key feature of ALS pathology. These findings establish ALS04 as a promising noninvasive imaging tool for monitoring biomarkers associated with ALS progression. Its ability to detect early-stage pathophysiological changes in an ALS mouse model highlights its potential for advancing our understanding of ALS mechanisms and facilitating the identification of novel therapeutic targets.

Abstract
Platinum-based anticancer agents have revolutionized oncological treatments globally. However, their therapeutic efficacy is often accompanied by systemic toxicity. Carboplatin, recognized for its relatively lower toxicity profile than cisplatin, still presents off-target toxicities, including dose-dependent cardiotoxicity, neurotoxicity, and myelosuppression. In this study, we demonstrate a delivery strategy of carboplatin to mitigate its off-target toxicity by leveraging the potential of zwitterionic nanocarrier, H-dot. The designed carboplatin/H-dot complex (Car/H-dot) exhibits rapid drug release kinetics and notable accumulation in proximity to tumor sites, indicative of amplified tumor targeting precision. Intriguingly, the Car/H-dot shows remarkable efficacy in eliminating tumors across insulinoma animal models. Encouragingly, concerns linked to carboplatin-induced cardiotoxicity are effectively alleviated by adopting the Car/H-dot nanotherapeutic approach. This pioneering investigation not only underscores the viability of H-dot as an organic nanocarrier for platinum drugs but also emphasizes its pivotal role in ameliorating associated toxicities. Thus, this study heralds a promising advancement in refining the therapeutic landscape of platinum-based chemotherapy.

Abstract
Two of the most pressing challenges facing bioimaging are nonspecific uptake of intravenously administered contrast agents and incomplete elimination of unbound targeted agents from the body. Designing a targeted contrast agent that shows fast clearance from background tissues and eventually the body after complete targeting is key to the success of image-guided interventions. Here, this work describes the development of renally clearable near-infrared contrast agents and their potential use for dual-channel image-guided tumor targeting. cRGD-ZW800-PEG (800 nm channel) and ZW700-PEG (700 nm channel) are able to visualize tumor margins and tumor vasculature simultaneously and respectively. These targeted agents show rapid elimination from the bloodstream, followed by renal clearance, which together significantly lower off-target background signals and potential toxicity. To demonstrate its applicability, this multispectral imaging is performed in various tumor-bearing animal models including lung cancer, pancreatic neuroendocrine tumors, breast, and ovarian cancer.

Abstract
Photodynamic therapy (PDT) has become a potential anti-cancer strategy owing to its negligible invasiveness, low toxicity, and high selectivity. The photosensitizer (PS) plays an indispensable role in PDT. Herein, a novel type of PS (Ce6-MB@Lips) which can be excited by a near-infrared (NIR) laser was designed and synthesized. Methylene blue (MB) and Chlorin e6 (Ce6), two organic dyes approved by the Food and Drug Administration (FDA), were used to prepare Ce6-MB@Lips by thin-film dispersion method, which improve the water solubility of Ce6 and reduce the cytotoxicity of MB. The Ce6-MB@Lips were shown to have a spherical nanostructure with an average particle size of 160.3 nm and excellent water solubility. Then the optical properties of Ce6-MB@Lips were further studied. Ce6-MB@Lips showed absorption peaks at 413 nm/670 nm and fluorescence peak at 697 nm. Compared with Ce6@Lips and MB@Lips, Ce6-MB@Lips showed better stability, stronger fluorescence intensity, and higher singlet oxygen (1O2) generation ability. Cell experimental analysis exhibited that the stable Ce6-MB@Lips showed low cytotoxicity, high phototoxicity and high reactive oxygen species (ROS) production capacity. After effective cell internalization, the prepared Ce6-MB@Lips showed excellent ability to promote tumor cell apoptosis in vitro. The Ce6-MB@Lips could be a promising candidate for PDT of cervical cancer.

Abstract
Cancer surgery requires removing the tumor tissue in necessary and sufficient quantities. Spectral optical imaging in the short-wave infrared (900-1700 nm) could provide an intraoperative guidance to the surgeon based on the absorption of the tissues without contrast agent. Our objective was to ensure the safety of our ENDOSWIR device on human tissues. Histological analysis of fresh human tonsils exposed to the SWIR light or not was compared and showed no histological differences. This demonstrates the safety of using the SWIR device on human tissues and allows us to initiate a clinical study for the resection of tumors intraoperatively.

Abstract
The residual tumor after surgery is the most significant prognostic factor of patients with epithelial ovarian cancer. Near-infrared (NIR) fluorescence-guided surgery is actively utilized for tumor localization and complete resection during surgery. However, currently available contrast-enhancing agents display low on-target binding, unfavorable pharmacokinetics, and toxicity, thus not ideal for clinical use. Here we report ultrabright and stable squaraine fluorophores with optimal pharmacokinetics by introducing an asymmetric molecular conformation and surface charges for rapid transporter-mediated cellular uptake. Among the tested, OCTL14 shows low serum binding and rapid distribution into cancer tissue via organic cation transporters (OCTs). Additionally, the charged squaraine fluorophores are retained in lysosomes, providing durable intraoperative imaging in a preclinical murine model of ovarian cancer up to 24 h post-injection. OCTL14 represents a significant departure from the current bioconjugation approach of using a non-targeted fluorophore and would provide surgeons with an indispensable tool to achieve optimal resection.

Abstract
INTRODUCTION Congenital hyperinsulinism (CHI) has diffuse (CHI-D), focal (CHI-F) and atypical (CHI-A) forms. Surgical management depends on preoperative [18F]-DOPA PET/CT and intraoperative morphological differential diagnosis of CHI forms. Objective: to improve differential diagnosis of CHI forms by comparative analysis [18F]-DOPA PET/CT data, as well as cytological, histological and immunohistochemical analysis (CHIA). MATERIALS AND METHODS The study included 35 CHI patients aged 3.2 ± 2.0 months; 10 patients who died from congenital heart disease at the age of 3.2 ± 2.9 months (control group). We used PET/CT, CHIA of pancreas with antibodies to ChrA, insulin, Isl1, Nkx2.2, SST, NeuroD1, SSTR2, SSTR5, DR1, DR2, DR5; fluorescence microscopy with NeuroD1/ChrA, Isl1/insulin, insulin/SSTR2, DR2/NeuroD1 cocktails. RESULTS Intraoperative examination of pancreatic smears showed the presence of large nuclei, on average, in: 14.5 ± 3.5 cells of CHI-F; 8.4 ± 1.1 of CHI-D; and 4.5 ± 0.7 of control group (from 10 fields of view, x400). The percentage of Isl1+ and NeuroD1+endocrinocytes significantly differed from that in the control for all forms of CHI. The percentage of NeuroD1+exocrinocytes was also significantly higher than in the control. The proportion of ChrA+ and DR2+endocrinocytes was higher in CHI-D than in CHI-F, while the proportion of insulin+cells was higher in CHI-A. The number of SST+cells was significantly higher in CHI-D and CHI-F than in CHI-A. CONCLUSION For intraoperative differential diagnosis of CHI forms, in addition to frozen sections, quantitative cytological analysis can be used. In quantitative immunohistochemistry, CHI forms differ in the expression of ChrA, insulin, SST and DR2. The development of a NeuroD1 inhibitor would be advisable for targeted therapy of CHI.
