Immunotherapy has a great potential in advancing cancer treatment, especially in light of recent discoveries and therapeutic interventions that lead to complete response in specific subgroups of melanoma patients. By using the body's own immune system, it is possible not only to specifically target and eliminate cancer cells while leaving healthy cells unharmed but also to elicit long-term protective response. Despite the promise, current immunotherapy is limited and fails in addressing all tumor types. This is probably due to the fact that a single treatment strategy is not sufficient in overcoming the complex antitumor immunity. The use of nanoparticle-based system for immunotherapy is a promising strategy that can simultaneously target multiple pathways with the same kinetics to enhance antitumor response. Here, we will highlight the recent advances in the field of cancer immunotherapy that utilize lipid-based nanoparticles as delivery vehicles and address the ongoing challenges and potential opportunities.

The global prevalence of Parkinson's Disease (PD) is on the rise, driven by an ageing population and ongoing environmental conditions. To gain a better understanding of PD pathogenesis, it is essential to consider its relationship with the ageing process, as ageing stands out as the most significant risk factor for this neurodegenerative condition. PD risk factors encompass genetic predisposition, exposure to environmental toxins, and lifestyle influences, collectively increasing the chance of PD development.

The development of disease-modifying therapeutics for Alzheimer's disease remains challenging due to the complex pathology and the presence of the blood-brain barrier. Previously we have described the investigation of a brain-penetrating multifunctional bioreactive nanoparticle system capable of remodeling the hypoxic and inflammatory brain microenvironment and reducing beta-amyloid plaques improving cognitive function in a mouse model of Alzheimer's disease. Despite the linkage of hypoxia and inflammation to metabolic alteration, the effects of this system on modulating cerebral glucose metabolism, mitochondrial activity and synaptic function remained to be elucidated.

Objective: The fabrication of furosemide (FSM) with enhanced oral bioavailability and encapsulation was achieved using a nanostructured lipid carriers (NLCs) drug delivery system.: The uniform drug distribution is a barrier due to its low dose. The lipid-based delivery system was selected based on its poor solubility and permeability, limiting its poor partitioning and solubility in water-based polymeric delivery systems.

Various lipid and biopolymer-based nanocarriers have been developed to encapsulate food ingredients. The selection of nanocarrier type, preparation techniques, and loading methods should consider the compatibility of nutrient properties, nanocarrier composition, and product requirements. This review focuses on the loading methods for hydrophilic and hydrophobic substances, along with a detailed exploration of nanocarrier categorization, composition, and preparation methods.
