Binding of RNA Aptamers to Membrane Lipid Rafts: Implications for Exosomal miRNAs Transfer from Cancer to Immune Cells

2020

Intraluminal vesicles (ILVs) are released into the extracellular space as exosomes after the fusion of multivesicular bodies (MVBs) with the plasma membrane. miRNAs are delivered to the raft-like region of MVB by RNA-binding proteins (RBPs). RNA loading into exosomes can be either through direct interaction between RNA and the raft-like region of the MVB membrane, or through interaction between an RBP&ndash

Musical interaction in music therapy for depression treatment

2022

Music therapy is efficacious for the treatment of depression. Compared to other psychotherapeutic forms, it allows for the emergence of various modes of mutual interaction, thus enabling multiple channels for emotional expression and fostering therapeutic alliance. Although musical interaction patterns between client and therapist have been regarded as predictors of therapeutic outcome in depression, this has not yet been systematically investigated. We aim to address this gap by analyzing the possible linkage between musical interaction features and changes in depression score. In a clinical trial, digital piano improvisations from 58 Finnish clients and their therapists were recorded ove…

The affinities of monoclonal antibodies against core antigen of hepatitis B virus

1994

Four monoclonal antibodies generated against the recombinant core antigen of hepatitis B virus are investigated for antigen binding. All exhibit a similar affinity to polystyrene-sorbed antigen but only one of them interacts with native form of HBcAg (an assembled particle) in solution. The presence of 0.1% sodium dodecylsulphate is required for the binding of other three antibodies. The phenomenon can be interpreted as inaccessibility of the corresponding epitopes unless the multimeric antigen structure is disrupted. The core antigen coated on polystyrene is considered as a similar exposed structure.

Monoclonal antibody 3H8: A useful tool in the diagnosis of candidiasis

1999

In a previous series of experiments six mAbs were obtained against cell wall extracts of Candida albicans ATCC 26555. After several studies only one of them, designated 3H8, has been used to produce a commercial kit for the rapid diagnosis of candidiasis, Bichro-latex albicans (Fomouze Diagnostics). The present study involved the generation and characterization of this mAb as an immunoglobulin G1 which recognizes mannoproteins of high molecular mass present in the C. albicans cell wall. ELISA assays showed that the presence of the epitope recognized by mAb 3H8 was similar in both yeast and mycelial cell walls of C. albicans, in contrast to the epitope for mAb 1B12, which is mainly expressed…

Optical biosensor-based characterization of anti-double-stranded DNA monoclonal antibodies as possible new standards for laboratory tests.

2009

The serum determination of circulating anti-double-stranded (ds)DNA autoantibodies is a routine measure for the laboratory diagnosis of systemic lupus erythematosus. Since available assays differ substantially and no feasible calibrator is available, the aim of this study was to evaluate a recently introduced surface plasmon resonance (SPR) biosensor chip for binding studies between dsDNA and anti-dsDNA autoantibodies and to demonstrate its usefulness for the characterization of new monoclonal antibody (mAb) standards and standardization of assays. We characterized two human and one murine monoclonal anti-dsDNA antibodies by measuring the kinetic on- and off-rates using the biosensor and ca…

Monoclonal antibody TeM 106 reacts with a tonoplast intrinsic protein of 106 kDa from Brassica oleracea L

1995

A monoclonal antibody, designated TeM 106, that recognizes an intrinsic protein from the vacuole membrane (tonoplast) of cauliflower (Brassica oleracea L. var. botrytis) is described. Mice were immunized with a tonoplast fraction that had been purified from differentiating meristematic cells from the cauliflower head. Hybridomas were generated and screened by means of Enzyme Linked Immuno Sorbent Assays for differential reactivity to tonoplast over non-related proteins (bovine serum albumin). One out of 14 reactive murine clones was selected on the basis of its stability, secretory efficiency, and high affinity of the secreted antibodies. TeM 106 is an IgM which was shown by indirect immuno…

Identification and characterization of a monoclonal antibody to the membrane fatty acid binding protein

1992

A monoclonal antibody to the rat liver membrane fatty acid binding protein (MFABP) was prepared by immunizing mice with purified MFABP isolated from solubilized rat liver plasma membrane proteins by oleate-agarose affinity chromatography technique. The monoclonal antibody K15/6 identified a single 40 kDa protein in rat liver plasma membranes with pI values of 8.5, 8.8 and 9.0, which is identical to the authentic MFABP, but clearly distinct from rat mitochondrial GOT. The antibody K15/6 selectively inhibited cellular influx as well as membrane binding of fatty acids, but not of cholesterol or vitamin E. The same antibody was used in immunofluorescence, ELISA and Western blot analysis to dete…

Liver cell damage caused by monoclonal antibody against an organ-specific membrane antigen in vivo and in vitro

1987

Summary Monoclonal antibodies have been raised against different antigenic determinants of normal rabbit hepatocytes. One antibody (2D3) recognized a liver-specific 43 kDa protein displayed exclusively on the basolateral portion of the hepatocellular membrane. Purified monoclonal antibodies were injected intravenously into rabits. Following the injection of antibody 2D3, a dose-dependent increase of liver enzyme activities in sera was observed. Within 8 h, marked morphological alterations of the hepatocytes, including multiple cell necroses, could be demonstrated by light and electron microscopy. When isolated vital rabbit hepatocytes in culture were used as targets, cytotoxic effects of th…
