Comparison of 3 anti-PLA2R inmmunoassaysfor the diagnosis of idiopathic membranous nephropathy in an european population. A pilot study.

Clin Immunol 2021 Apr 16:108729. Epub 2021 Apr 16.

Immunology Department, Hospital Ramón y Cajal, Ctra. Colmenar Viejo, Km 9,100, 28034 Madrid, Spain. Electronic address:

Membranous nephropathy (MN) is one of the most frequent causes of nephrotic syndrome. Renal biopsy is nowadays the gold standard for the diagnosis of MN. The presence of circulating PLA2R antibody is a very specific tool for the diagnosis of this disease, especially associated with primary or idiopathic MN (IMN), even though it can be also found in a small proportion of patients with secondary MN (SMN).

Evaluation of the Immunogenic Response of a Novel Enterobactin Conjugate Vaccine in Chickens for the Production of Enterobactin-Specific Egg Yolk Antibodies.

Front Immunol 2021 2;12:629480. Epub 2021 Apr 2.

Department of Animal Science, The University of Tennessee, Knoxville, TN, United States.

Passive immunization with specific egg yolk antibodies (immunoglobulin Y, IgY) is emerging as a promising alternative to antibiotics to control bacterial infections. Recently, we developed a novel conjugate vaccine that could trigger a strong immune response in rabbits directed against enterobactin (Ent), a highly conserved siderophore molecule utilized by different Gram-negative pathogens. However, induction of Ent-specific antibodies appeared to be affected by the choice of animal host and vaccination regimen. Read More

Immunohistochemical localization and pharmacokinetics of the anti-MRSA drug teicoplanin in rat kidney using a newly developed specific antibody.

Med Mol Morphol 2021 Apr 17. Epub 2021 Apr 17.

Department of Applied Life Science, Faculty of Biotechnology and Life Science, Sojo University, 4-22-1 Ikeda, Nishi-ku, Kumamoto, 860-0082, Japan.

We prepared a polyclonal antibody against a teicoplanin (TEIC)-bovine serum albumin conjugate that was specific to both conjugated and free forms of TEIC. We demonstrated that this antibody could be used to detect the time-dependent localization of TEIC in rat kidneys. Immunohistochemistry revealed immunoreactivity specifically in the microvilli and apical cytoplasm of epithelial cells in proximal tubule segments S1 and S2, 1 h after intravenous TEIC injection, with higher staining intensity in the S2 segments.

Homogeneous tumor targeting with a single dose of HER2-targeted albumin-binding domain-fused nanobody-drug conjugates results in long-lasting tumor remission in mice.

Theranostics 2021 13;11(11):5525-5538. Epub 2021 Mar 13.

Cell Biology, Neurobiology and Biophysics, Department of Biology, Faculty of Science, Utrecht University, Utrecht, The Netherlands.

The non-homogenous distribution of antibody-drug conjugates (ADCs) within solid tumors is a major limiting factor for their wide clinical application. Nanobodies have been shown to rapidly penetrate into xenografts, achieving more homogeneous tumor targeting. However, their rapid renal clearance can hamper their application as nanobody drug conjugates (NDCs). Read More

The Most Active Oxidase-mimicking Mn2O3 Nanozyme for Biosensor Signal Generation.

Chemistry 2021 Apr 15. Epub 2021 Apr 15.

University of Waterloo, Department of Chemistry, 200 University Avenue West, N2L 3G1, Waterloo, CANADA.

Oxidase-mimicking nanozymes are more desirable than peroxidase-mimicking ones since H 2 O 2 can be omitted. However, only a few nanomaterials are known for oxidase-like activities. In this work, we compared the activity of Mn 2 O 3 , Mn 3 O 4 and MnO 2 and found that Mn 2 O 3 had the highest oxidase activity. Read More

Recognition of acrolein-specific epitopes by B cell receptors triggers an innate immune response.

J Biol Chem 2021 Apr 8:100648. Epub 2021 Apr 8.

Graduate School of Agricultural and Life Sciences, The University of Tokyo, Tokyo, 113-8657, Japan; Japan Agency for Medical Research and Development, CREST, Tokyo, Japan. Electronic address:

Natural antibodies, predominantly immunoglobulin M (IgM), play an important role in the defense against pathogens and in maintaining homeostasis against oxidized molecules known as oxidation-specific epitopes, such as those contained in oxidized low-density lipoproteins. However, due to the complexity of the oxidized products, very few individual epitopes have been characterized in detail. In the present study, to identify endogenous sources of oxidation-specific epitopes, we stimulated mouse spleen and peritoneal cavity (PerC) cells in vitro with bovine serum albumin (BSA) modified with a variety of lipid peroxidation-related carbonyl compounds, and identified the acrolein-modified BSA (acrBSA) as the most efficient trigger studied for the production of IgM in PerC cells.

An injectable micelle-hydrogel hybrid for localized and prolonged drug delivery in the management of renal fibrosis.

Acta Pharm Sin B 2021 Mar 18;11(3):835-847. Epub 2020 Oct 18.

Key Laboratory of Drug-Targeting and Drug Delivery System of the Education Ministry and Sichuan Province, Sichuan Engineering Laboratory for Plant-Sourced Drug and Sichuan Research Center for Drug Precision Industrial Technology, West China School of Pharmacy, Sichuan University, Chengdu 610041, China.

Localized delivery, comparing to systemic drug administration, offers a unique alternative to enhance efficacy, lower dosage, and minimize systemic tissue toxicity by releasing therapeutics locally and specifically to the site of interests. Herein, a localized drug delivery platform ("plum‒pudding" structure) with controlled release and long-acting features is developed through an injectable hydrogel ("pudding") crosslinked self-assembled triblock polymeric micelles ("plum") to help reduce renal interstitial fibrosis. This strategy achieves controlled and prolonged release of model therapeutics in the kidney for up to three weeks in mice. Read More

Qualitative and semiquantitative assessment of thyroid hormone binding proteins in greyhounds and other dog breeds.

Domest Anim Endocrinol 2021 Feb 23;76:106623. Epub 2021 Feb 23.

School of Veterinary Medicine, University College Dublin, Belfield, Dublin, Ireland.

Total thyroxine (T4) concentrations are lower in healthy greyhounds compared to most other non-sighthound breeds. In humans, variations in the structure or concentration of the major thyroid hormone binding proteins are responsible for most reported differences between total T4 concentrations in healthy individuals from different ethnic groups or other subpopulations. The aim of this study was to determine if such variations are also responsible for the lower total T4 concentrations in greyhounds. Read More

Albumin in Advanced Liver Diseases: The Good and Bad of a Drug!

Hepatology 2021 Mar 27. Epub 2021 Mar 27.

Department of Hepatology, Institute of Liver and Biliary Sciences, New Delhi, India.

Human serum albumin (HSA) is the most abundant plasma protein and it regulates diverse body functions. In advanced and decompensated cirrhosis patients, serum albumin levels are low due to reduction in hepatocyte mass and loss due to disease per se and multiple therapeutic interventions. Due to its oncotic and non-oncotic properties, administration of human albumin solutions (HAS) has been found to be beneficial in patients undergoing large volume paracentesis, hepatorenal syndrome and spontaneous bacterial peritonitis.
