Alginate Microsponges as a Scaffold for Delivery of a Therapeutic Peptide against Rheumatoid Arthritis. NANOMATERIALS (BASEL, SWITZERLAND) 2023; 13:2709. [PMID: 37836350 PMCID: PMC10574729 DOI: 10.3390/nano13192709] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/28/2023] [Accepted: 10/03/2023] [Indexed: 10/15/2023]
Abstract
The quest for biocompatible drug-delivery devices that could be able to open new administration routes is at the frontier of biomedical research. In this contribution, porous polysaccharide-based microsponges based on crosslinked alginate polymers were developed and characterized by optical spectroscopy and nanoscopic microscopy techniques. We show that macropores with a size distribution ranging from 50 to 120 nm enabled efficient loading and delivery of a therapeutic peptide (CIGB814), presently under a phase 3 clinical trial for the treatment of rheumatoid arthritis. Alginate microsponges showed 80% loading capacity and sustained peptide release over a few hours through a diffusional mechanism favored by partial erosion of the polymer scaffold. The edible and biocompatible nature of alginate polymers open promising perspectives for developing a new generation of polysaccharide-based carriers for the controlled delivery of peptide drugs, exploiting alternative routes with respect to intravenous administration.

Abstract
Abstract
Purpose of Review
The regenerative capacity of the heart is insufficient to compensate for the pathological loss of cardiomyocytes during a large injury, such as a myocardial infarction. Therapeutic options for patients after cardiac infarction are limited: treatment with drugs that only treat the symptoms or extraordinary measures, such as heart transplantation. Cell therapies offer a promising strategy for cardiac regeneration. In this brief review, the major issues in these areas are discussed, and possible directions for future research are indicated.
Recent Findings
Cardiac regeneration can be obtained by at least two strategies: the first is direct to generate an ex vivo functional myocardial tissue that replaces damaged tissue; the second approach aims to stimulate endogenous mechanisms of cardiac repair. However, current cell therapies are still hampered by poor translation into actual clinical applications.
Summary
In this scenario, recent advancements in cell biology and biomaterial-based technologies can play a key role to design effective therapeutic approaches.

Abstract
Modulation of macrophage plasticity is emerging as a successful strategy in tissue engineering (TE) to control the immune response elicited by the implanted material. Indeed, one major determinant of success in regenerating tissues and organs is to achieve the correct balance between immune pro-inflammatory and pro-resolution players. In recent years, nanoparticle-mediated macrophage polarization towards the pro- or anti-inflammatory subtypes is gaining increasing interest in the biomedical field. In TE, despite significant progress in the use of nanomaterials, the full potential of nanoparticles as effective immunomodulators has not yet been completely realized. This work discusses the contribution that nanotechnology gives to TE applications, helping native or synthetic scaffolds to direct macrophage polarization; here, three bioactive metallic and ceramic nanoparticles (gold, titanium oxide, and cerium oxide nanoparticles) are proposed as potential valuable tools to trigger skeletal muscle regeneration.
