Article Abstract
Type 1 diabetes is an autoimmune disease characterized by the destruction of insulin-producing pancreatic β-cells, leading to hyperglycemia and various complications. Despite insulin replacement therapy, there is a need for therapies targeting the underlying autoimmune response. This review aims to explore the mechanistic insights into T1D pathogenesis and the impact of delivery systems on immunotherapy. Genetic predisposition and environmental factors contribute to T1D development, triggering an immune-mediated attack on β-cells. T cells, particularly CD4+ and CD8+ T cells, play a central role in β-cell destruction. Antigen- specific immunotherapy is a unique way to modify the immune system by targeting specific antigens (substances that trigger the immune system) for immunotherapy. It aims to restore immune tolerance by targeting autoantigens associated with T1D. Nanoparticle-based delivery systems offer precise antigen delivery, promoting immune tolerance induction. Various studies have demonstrated the efficacy of nanoparticle-mediated delivery of autoantigens and immunomodulatory agents in preclinical models, and several patents have been made in T1D. Combining antigen-specific immunotherapy with β-cell regeneration strategies presents a promising approach for T1D treatment. However, challenges remain in optimizing delivery systems for targeted immune modulation while ensuring safety and efficacy.

Statins as Antifungal Agents: A Review on Drug Repurposing and Nanotechnology-Driven Delivery Strategies.

Postgraduate Program in Pharmaceutical Science, Federal University of Juiz de Fora, Juiz de Fora, Minas Gerais, Brazil.
This review highlights the integration of drug repurposing and nanotechnology-driven delivery strategies as innovative approaches to enhance the antifungal activity of statins against mucosal candidiasis, providing a framework for future translational research and clinical application. The rising prevalence of antifungal resistance and virulence factors of Candida albicans underscore the limitations of current therapies. Statins, commonly used as lipid-lowering agents, have emerged as attractive repurposed drug candidates due to their ability to interfere with fungal ergosterol biosynthesis and Ras-mediated signaling pathways.

Low-grade non-muscle invasive bladder cancer is a specific category of bladder cancer with a favourable prognosis; however, its management presents several challenges. The risk of stage progression is very low, but approximately half of patients will experience recurrence within the first 5 years after diagnosis. This high propensity for recurrence, coupled with the threat of progression, mandates ongoing surveillance.

Carbonaceous asteroids are the source of the most primitive meteorites and represent leftover planetesimals that formed from ice and dust in the outer Solar System and may have delivered volatiles to the terrestrial planets. Understanding the aqueous activity of asteroids is key to deciphering their thermal, chemical and orbital evolution, with implications for the origin of water on the terrestrial planets. Analyses of the objects, in particular pristine samples returned from asteroid Ryugu, have provided detailed information on fluid-rock interactions within a few million years after parent-body formation.

Bacteriophages are the most abundant entities on earth and exhibit vast genetic and phenotypic diversity. Exploitation of this largely unexplored molecular space requires identification and functional characterization of genes that act at the phage-host interface. So far, this has been restricted to few model phage-host systems that are amenable to genetic manipulation.

Background: The mechanisms contributing to epidural-related maternal hyperthermia remain unclear. One explanation is that blockade of cholinergic sympathetic nerves prevents active vasodilation and sweating. However, it is not known how labour epidural analgesia affects cutaneous sympathetic function.
