Applications of Surface Plasmon Resonance and Biolayer Interferometry for Virus–Ligand Binding. Viruses 2022; 14:v14040717. [PMID: 35458446 PMCID: PMC9027846 DOI: 10.3390/v14040717] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 03/20/2022] [Accepted: 03/26/2022] [Indexed: 02/01/2023] Open
Abstract
Surface plasmon resonance and biolayer interferometry are two common real-time and label-free assays that quantify binding events by providing kinetic parameters. There is increased interest in using these techniques to characterize whole virus-ligand interactions, as the methods allow for more accurate characterization than that of a viral subunit-ligand interaction. This review aims to summarize and evaluate the uses of these technologies specifically in virus–ligand and virus-like particle–ligand binding cases to guide the field towards studies that apply these robust methods for whole virus-based studies.

Polymalic acid chlorotoxin nanoconjugate for near-infrared fluorescence guided resection of glioblastoma multiforme. Biomaterials 2019; 206:146-159. [PMID: 30933776 PMCID: PMC6574176 DOI: 10.1016/j.biomaterials.2019.03.029] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Revised: 03/01/2019] [Accepted: 03/19/2019] [Indexed: 12/19/2022]
Abstract
Maximal surgical resection of glioma remains the single most effective treatment. Tools to guide the resection while avoiding removal of normal brain tissues can aid surgeons in achieving optimal results. One strategy to achieve this goal is to rely upon interoperative fluorescence staining of tumor cells in vivo, that can be visualized by the surgeon during resection. Towards this goal we have designed a biodegradable fluorescent mini nano imaging agent (NIA) with high specificity for U87MG glioma cells and previously unmet high light emission. The NIA is the conjugate of polymalic acid (PMLA) with chlorotoxin for tumor targeting, indocyanine green (ICG) for NIR fluorescence and the tri-leucin peptide as fluorescence enhancer. PMLA as a multivalent platform carries several molecules of ICG and the other ligands. The NIA recognizes multiple sites on glioma cell surface, demonstrated by the effects of single and combined competitors. Systemic IV injection into xenogeneic mouse model carrying human U87MG glioblastoma indicated vivid tumor cell binding and internalization of NIA resulting in intensive and long-lasting tumor fluorescence. The NIA is shown to greatly improve tumor removal supporting its utility in clinical applications.

Abstract
Natural killer (NK) cells play a key role in host defense against microbial pathogens. Establishing the reference intervals (RIs) of NK cell functions would be valuable in assessing the immune status of hosts. We evaluated the NK cell activity in healthy adults. We further established and validated the RIs of representative NK cell functions. Flow cytometry was used to evaluate the cytokine production and CD107a degranulation of NK cells. Levels of soluble IFN-γ in the culture supernatants were evaluated by ELISA. Our results demonstrated that the intracellular IFN-γ production of NK cells was positively correlated with CD107a expression and soluble IFN-γ levels. There were no significant differences in NK cell functions between different age and gender groups. The mean values and RIs of representative NK cell functions are as following: IFN-γ(+) NK cells (%): 28.09 (11.3-51.95); CD107a(+) NK cells (%): 17.90 (9.852-27.56); soluble IFN-γ (pg/ml): 330.4 (41.38-717.8). In addition, the intracellular IFN-γ production and degranulation activity of NK cells in patients with colorectal cancer were significantly lower than that in healthy adults. Our study has established the RIs of NK cell functions in healthy adults, which might be used for monitoring the immune status of the hosts.

Receptor occupancy assessment by flow cytometry as a pharmacodynamic biomarker in biopharmaceutical development. CYTOMETRY PART B-CLINICAL CYTOMETRY 2015; 90:117-27. [PMID: 26054054 PMCID: PMC5042057 DOI: 10.1002/cyto.b.21259] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2014] [Revised: 04/20/2015] [Accepted: 05/28/2015] [Indexed: 12/19/2022]
Abstract
Receptor occupancy (RO) assays are designed to quantify the binding of therapeutics to their targets on the cell surface and are frequently used to generate pharmacodynamic (PD) biomarker data in nonclinical and clinical studies of biopharmaceuticals. When combined with the pharmacokinetic (PK) profile, RO data can establish PKPD relationships, which are crucial for informing dose decisions. RO is commonly measured by flow cytometry on fresh blood specimens and is subject to numerous technical and logistical challenges. To ensure that reliable and high quality results are generated from RO assays, careful assay design, key reagent characterization, data normalization/reporting, and thorough planning for implementation are of critical importance during development. In this article, the authors share their experiences and perspectives in these areas and discuss challenges and potential solutions when developing and implementing a flow cytometry‐based RO method in support of biopharmaceutical drug development. © 2015 The Authors Cytometry Part B: Clinical Cytometry Published by Wiley Periodicals, Inc.
