Antibody-Functionalized Carnauba Wax Nanoparticles to Target Breast Cancer Cells.Development of safer nanomedicines for drug delivery applications requires immense efforts to improve clinical outcomes. Targeting a specific cell, biocompatibility and biodegradability are vital properties of a nanoparticle to fulfill the safety criteria in medical applications. Herein, we fabricate antibody-functionalized carnauba wax nanoparticles encapsulated a hydrophobic drug mimetic, which is potentially interesting for clinical use due to the inert and nontoxic properties of natural waxes. The nanoparticles are synthesized applying miniemulsion methods by solidifying molten wax droplets and further evaporating the solvent from the dispersion. The pH-selective adsorption of antibodies (IgG1, immunoglobulin G1, and CD340, an antihuman HER2 antibody) onto the nanoparticle surface is performed for practical and effective functionalization, which assists to overcome the complexity in chemical modification of carnauba wax. The adsorption behavior of the antibodies is studied using isothermal titration calorimetry (ITC), which gives thermodynamic parameters including the enthalpy, association constant, and stoichiometry of the functionalization process. Both antibodies exhibit strong binding at pH 2.7. The CD340-decorated wax nanoparticles show specific cell interaction toward BT474 breast cancer cells and retain the targeting function even after 6 months of storage period.

Alloantibodies after simultaneous liver-kidney transplant: A story of primary nonfunction, retransplantation, and antibody-mediated rejection.Simultaneous liver-kidney transplant (SLKT) in the presence of antihuman leukocyte antigen (HLA) donor-specific antibodies (DSA) is a well-accepted practice. Herein, we describe the evolution of alloantibodies in a patient who received an SLKT. The pre-SLKT serum sample showed multiple strong DSA. As expected, all DSA cleared in a sample collected 4Â days after the SLKT. Because of the primary nonfunction of the liver in the SLKT, the patient had a second liver transplant 4Â days later. An abrupt increase in DSA levels against the kidney was detected 10Â days after the second liver transplant. These DSA were refractory to treatment, and the transplanted kidney was lost due to antibody-mediated rejection (AMR). A detailed study of the HLA epitopes recognized by DSA and, after normalization with third-party alloantibodies to address the effect of multiple transfusions and liver allograft neutralization, showed that the elimination of these antibodies depended on the HLA antigens expressed by the transplanted liver cells. The return of DSA after removal of the first transplanted liver was associated with AMR in the transplanted kidney.

Bavachin produces immunoadjuvant activity by targeting the NFAT signaling pathway.Bavachin, a flavonoid compound isolated from the seeds and fruits of Psoralea corylifolia l. (family Fabaceae), is used as a traditional medicine in Asia. Indeed, it is reported to have various medicinal functions such as estrogenic and antiinflammatory activities among others. However, to date, the effects of bavachin on T cell activation have yet to be reported.

Trastuzumab-Induced Negative Chronotropic and Lusitropic Effects in Cynomolgus Monkeys.Treatment with trastuzumab, an antihuman epidermal growth factor receptor type 2 humanized monoclonal antibody, has been associated with heart failure in certain patients with cancer; however, the mechanism underlying trastuzumab-induced cardiac dysfunction remains unclear. This study was conducted to clarify the cardiac effects of trastuzumab in cynomolgus monkeys, which are commonly used as cross-reactive species in preclinical safety evaluation. Monkeys were treated with trastuzumab weekly for 1 month (5 doses in total). At first and fifth doses for pressure-volume loop analysis, trastuzumab at 20 mgÂ·kg-1Â·10 min-1, equivalent to the human therapeutic dose, was administered intravenously to isoflurane-anesthetized animals, followed by 60 mgÂ·kg-1Â·10 min-1 at a 30-minute interval. The other doses were fixed at 80 mgÂ·kg-1Â·10 min-1 under unanesthetized conditions. After the first dose, reduced heart rate, decreases in maximal rate of fall of left ventricular pressure, and prolonged time constant for isovolumic relaxation, which are predictors of drug-induced changes in lusitropy, were observed at 20 and 60 mgÂ·kg-1. The changes after the fifth dose were comparable with those after the first dose, indicating trastuzumab did not show exacerbation of cardiac function during the 1-month trial. No significant changes in slope of preload recruitable stroke work, which is a load-independent inotropic parameter, were observed at either dose. In conclusion, trastuzumab-induced little inotropic effect but induced negative chronotropic or lusitropic effects in monkeys, which might be associated with impaired left ventricular diastolic function.

A resource of high-quality and versatile nanobodies for drug delivery.Therapeutic and diagnostic efficacies of small biomolecules and chemical compounds are hampered by suboptimal pharmacokinetics. Here, we developed a repertoire of robust and high-affinity antihuman serum albumin nanobodies (Nb) that can be readily fused to small biologics for half-life extension. We characterized the thermostability, binding kinetics, and cross-species reactivity of Nbs, mapped their epitopes, and structurally resolved a tetrameric HSA-Nb complex. We parallelly determined the half-lives of a cohort of selected Nbs in an HSA mouse model by quantitative proteomics. Compared to short-lived control nanobodies, the half-lives of Nbs were drastically prolonged by 771-fold. Nbs have distinct and diverse pharmacokinetics, positively correlating with their albumin binding affinities at the endosomal pH. We then generated stable and highly bioactive Nb-cytokine fusion constructs "Duraleukin" and demonstrated Duraleukin's high preclinical efficacy for cancer treatment in a melanoma model. This high-quality and versatile Nb toolkit will help tailor drug half-life to specific medical needs.

Antitumor Effect of Saikosaponin A on Human Neuroblastoma Cells.Neuroblastoma (NB) is a highly metastatic tumor in children that develops in the sympathetic nervous system and has a low curative rate. Saikosaponin A (SSA), an active ingredient isolated from the root of Radix Bupleuri, is a natural compound with various pharmacological activities and shows good application prospects in antitumors. This study investigated the antihuman NB activity of SSA and underlying mechanisms associated with its actions.
