Following incubation with [14C]gamma-aminobutyric acid (GABA) or [3H]dopamine, slices of rat striatum were superfused with media containing 36 mM K+ or ethylenediamine (EDA), 1 or 5 mM. Both K+ and EDA induced a release being largely Ca2+-dependent, while the EDA-induced release was not. Whereas K+ also evoked a Ca2+-dependent release of [3H]dopamine, EDA evoked no release of dopamine. EDA may therefore have potential as a specific GABA releasing agent.

The infiltrative and diffuse nature of gliomas makes complete resection unfeasible. Unfortunately, regions of brain parenchyma with residual, infiltrative tumor are protected by the blood-brain barrier (BBB), making systemic chemotherapies, small-molecule inhibitors, and immunotherapies of limited efficacy. Low-frequency focused ultrasound (FUS) in combination with intravascular microbubbles can be used to disrupt the BBB transiently and selectively within the tumor and peritumoral region.

Age-related macular degeneration (AMD) is one of the leading causes of central vision loss in the elderly population. Bevacizumab, a full-length humanized monoclonal anti-VEGF antibody, is commonly used off-label drug to treat AMD. However, the dosing regimen of bevacizumab and other anti-VEGF antibodies requires monthly intravitreal injections followed by regular intravitreal injections at 4-16-week intervals.

Doxorubicin (DOX) is one of the most widely used chemotherapy drugs in the treatment of both solid and liquid tumors in patients of all age groups. However, it is likely to produce several side effects that include doxorubicin cardiomyopathy. Nanoparticles (NPs) can offer targeted delivery and release of the drug, potentially increasing treatment efficiency and alleviating side effects.

Autoimmune diseases present complex therapeutic challenges due to their chronic nature, systemic impact, and requirement for precise immunomodulation to avoid adverse side effects. Recent advancements in biodegradable and stimuli-responsive nanomaterials have opened new avenues for targeted drug delivery systems capable of addressing these challenges. This review provides a comprehensive analysis of state-of-the-art biodegradable nanocarriers such as polymeric nanoparticles, liposomes, and hydrogels engineered for targeted delivery in autoimmune therapies.

The present research aimed to assess the anti-cancer effects of the polysaccharide fraction (SJP) isolated from . The release of immune-activating cytokines, including IL-6, IL-12, and TNF-α, was markedly stimulated by the SJP in a concentration-dependent manner within the range of 1 to 100 µg/mL. Furthermore, the prophylactic intravenous () and per os () injection of SJP boosted the cytolytic activity mediated by NK cells and CTLs against tumor cells.
