A novel xenograft mouse model for testing approaches targeting human kappa light-chain diseases. Gene Ther 2019; 26:187-197. [PMID: 30926963 DOI: 10.1038/s41434-019-0070-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 02/01/2019] [Accepted: 03/11/2019] [Indexed: 02/06/2023]
Abstract
Patients with immunoglobulin (Ig) light-chain (LC) diseases such as LC light-chain amyloidosis die with organ failure and need new therapies. We sought a model to test anti-LC siRNA delivery to human plasma cells, requiring circulating LC, in vivo indicators of tumor presence, and capacity for multiple injections of delivery vehicle. The JJN-3 human myeloma reporter cell line expressing firefly luciferase (FFL) implanted intraperitoneally (IP) in the NOD scid γ (NSG) mouse has a 90% prompt tumor-take, rapid LC production, and in vivo indicators of tumor measurable on day 5 post-implant (κ LC, bioluminescent signal, and soluble B-cell maturation antigen [sBCMA]) with median day 5 serum levels of κ LC of 1482 ng/mL (range, 255-4831) and robust correlations with all in vivo indicators. In preliminary attempts to deliver siRNA against κ LC constant region mRNA, we identified the 306-O18B3 lipidoid nanoparticle (LNP) as promising, safe and efficient in vitro. In vivo in the JJN-3 NSG IP model, after daily IP 306-O18B3:siRNA injections on days 5-10, a reduction in κ LC was observed on day 8 between control and test groups that continued through day 12 at sacrifice. This model is potentially useful as a platform for refining anti-LC therapies.

Abstract
Intracellular delivery is a key step in biological research and has enabled decades of biomedical discoveries. It is also becoming increasingly important in industrial and medical applications ranging from biomanufacture to cell-based therapies. Here, we review techniques for membrane disruption-based intracellular delivery from 1911 until the present. These methods achieve rapid, direct, and universal delivery of almost any cargo molecule or material that can be dispersed in solution. We start by covering the motivations for intracellular delivery and the challenges associated with the different cargo types-small molecules, proteins/peptides, nucleic acids, synthetic nanomaterials, and large cargo. The review then presents a broad comparison of delivery strategies followed by an analysis of membrane disruption mechanisms and the biology of the cell response. We cover mechanical, electrical, thermal, optical, and chemical strategies of membrane disruption with a particular emphasis on their applications and challenges to implementation. Throughout, we highlight specific mechanisms of membrane disruption and suggest areas in need of further experimentation. We hope the concepts discussed in our review inspire scientists and engineers with further ideas to improve intracellular delivery.

Abstract
INTRODUCTION Systemic amyloidosis occurs when one of a growing list of circulating proteins acquires an abnormal fold, aggregates and gives rise to extracellular amyloid deposits in different body sites, leading to organ dysfunction and eventually death. Current approaches are mainly aimed at lowering the supply of the amyloidogenic precursor or at stabilizing it in a non-amyloidogenic state, thus interfering with the initial phases of amyloid formation and toxicity. Areas covered: Improved understanding of the pathophysiology is indicating novel steps and molecules that could be therapeutically targeted. Here, we will review emerging molecular targets and therapeutic approaches against the main forms of systemic amyloidosis at the early preclinical level. Expert opinion: Conspicuous efforts in drug design and drug discovery have provided an unprecedented list of potential new drugs or therapeutic strategies, from gene-based therapies to small molecules and peptides, from novel monoclonal antibodies to engineered cell-based therapies. The challenge will now be to validate and optimize the most promising candidates, cross the bridge from the preclinical phase to the clinics and identify, through innovative trials design, the safest and most effective combination therapies, striving for a better care, possibly a definitive cure for these diseases.
