Introduction: The oral route is a preferred method for drug administration; however, lipophilic drugs often suffer from poor water solubility, significantly limiting their therapeutic effectiveness. Traditional approaches like complexation, micronization, and solid dispersion have been explored, but each comes with inherent limitations.
Methods: Self-Emulsifying Drug Delivery Systems (SEDDS) have emerged as a promising strategy to address solubility challenges.
The ubiquitin-proteasome system (UPS) plays a critical role in protein homeostasis within eukaryotic cells. This review article examines the UPS's role in neuronal morphology and neurodegeneration through systematic analysis of current research. In neurodegenerative disorders (NDDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), UPS dysfunction contributes significantly to pathogenesis through accumulation of ubiquitinated misfolded proteins, disruption of cellular proteostasis, impaired substrate ubiquitination, and proteasomal deterioration.

Adult hippocampal neurogenesis (AHN), the continuous production of new neurons in the dentate gyrus, provides a unique form of structural plasticity essential for lifelong learning and memory. AHN is notably altered in various neurodegenerative and mental health disorders characterized by cognitive deficits, suggesting its crucial involvement in maintaining neuronal populations and endogenous regenerative capacity.

Parkinson's disease (PD) is a neurodegenerative disorder that is mainly caused by the degeneration of dopaminergic neurons of the substantia nigra. Although the pathological feature involves α-synuclein aggregation, recent findings suggest that systemic immune dysregulation is a key process in initiating and advancing the disease. This article seeks to untangle the complex molecular mechanisms that contribute to the immune response in PD, with specific emphasis on innate and adaptive immune processes.

Protein dyshomeostasis is identified as the hallmark of many age-related NDDs including Parkinson's disease (PD). PD is a progressive neurodegenerative disorder (NDD) characterized by the accumulation of misfolded proteins, particularly α-synuclein (α-syn) leading to formation of Lewy bodies and cause degeneration of dopaminergic neurons in substantia nigra pars compacta (SNpc). Disruption of the cell's normal protein balance, which occurs when cells experience stress, plays a key role in causing the formation of harmful protein clumps.

This review explores how IR promotes amyloidogenesis by disrupting cholesterol homeostasis and enhancing Amyloid beta (Aβ) production and aggregation. Specifically, we examine the role of ATP-binding cassette (ABC) transporters in cholesterol homeostasis along with their impact on insulin signaling pathways, highlights how their dysregulation can lead to IR, a significant contributor to the development of amyloidogenesis, a key factor in causing NDDs.

However, concern has been increasing about long-term use and some possible neurological adverse effects, including a link with dementia. Several studies indicate that long-term use of PPIs can raise the risk for both Alzheimer's disease (AD) and non-Alzheimer's dementia, though there is opposing evidence.

Nrf2, a crucial protein involved in defense mechanisms, particularly oxidative stress, plays a significant role in neurological diseases (NDs) by reducing oxidative stress and inflammation. NDs, including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, stroke, epilepsy, schizophrenia, depression, and autism, exhibit ferroptosis, iron-dependent regulated cell death resulting from lipid and iron-dependent reactive oxygen species (ROS) accumulation. Nrf2 has been shown to play a critical role in regulating ferroptosis in NDs.
