Immobilized hyaluronidase (nanotechnology method of electron-beam synthesis) exhibited high hepatoprotective activity on the model of Cl4-induced hepatitis. This agent produced anticholestatic, anti-inflammatory, and antisclerotic effects. These effects were shown to accompany stimulation of multipotent bone marrow precursors, mobilization of these cells into the peripheral blood, and cell migration to the target organ increasing the number of parenchymal progenitor cells in the liver. The mechanisms for targeted migration of progenitor cells suggest a decrease in SDF-1 production by bone marrow stromal cells and increase in the synthesis of this factor by microenvironmental cells of the liver tissue.

Psoriasis, a chronic autoimmune and non-communicable skin disease, affects 2-3% of the global population, creating a significant financial burden on healthcare systems worldwide. Treatment approaches are categorized based on disease severity, with first-line therapy focusing on topical treatments and second-line therapy encompassing phototherapy, systemic therapy, and biological therapy. Transdermal drug delivery methods present a promising alternative by enhancing drug absorption through the skin, potentially improving therapeutic outcomes while minimizing systemic adverse effects.

Different types of cancers affect the gastrointestinal tract (GIT), starting from the oral cavity and extending to the colon. In general, most of the current research focuses on the systemic delivery of the therapeutic agents, which leads to undesired side effects and a limited enhancement in the therapeutic outcomes. As a result, localized delivery within gastrointestinal (GI) cancers is favorable in overcoming these limitations.

The metabolic activity of tumor cells leads to the acidification of the surrounding microenvironment, which provides new strategies for the application of nanotechnology in cancer therapy. Researchers have developed various types of pH-responsive nanomaterials based on the tumor acidic microenvironment. This review provides an in-depth discussion on the design mechanisms, drug-loading strategies, and application pathways of tumor acidic microenvironment-responsive nanodrug delivery systems.

Renal dysfunction due to ischemia-reperfusion injury (IRI) is a common problem after kidney transplantation. In recent years, studies on animal models have shown that exosomes derived from mesenchymal stem cells (MSC-Exo) play an important role in treating acute kidney injury (AKI) and promoting tissue repair. The microneedle patch provides a noninvasive and targeted delivery system for exosomes.
