Alzheimer's disease (AD) is the most commonly occurring brain disorder, characterized by the accumulation of amyloid-β (Aβ) and tau, subsequently leading to neurocognitive decline. 3-Amino-1-propanesulfonic acid (TPS) and its prodrug, currently under clinical trial III, serve as promising therapeutic agents targeting Aβ pathology by specifically preventing monomer-to-oligomer formation. Inspired by the potency of TPS prodrug, we hypothesized that conjugating TPS with human serum albumin (HSA) could enhance brain delivery and synergistically inhibit Aβ aggregation in mild to moderate AD.

Background: The three-class oddball paradigm allows to investigate the processing of behaviorally relevant and irrelevant auditory stimuli. In humans, event-related potentials (ERPs) are used as neural correlate of behavior. We recorded local field potentials (LFPs) within the medial prefrontal cortex (mPFC) in rats during three-class and passive two-class oddball paradigms and analyzed the ERPs focusing on similarities to human recordings.

Head trauma from blast exposure is a growing health concern, particularly among active military personnel, and is considered the signature injury of the Gulf War. However, it remains elusive whether fundamental differences exist between blast-related Traumatic Brain Injuries (TBI) and TBI due to other mechanisms. Considering the importance of lipid metabolism associated with neuronal membrane integrity and its compromise during TBI, we sought to find changes in lipidomic profiling during blast or blunt (Stereotaxically Controlled Contusison-SCC)-mediated TBI.

Migraine patients often experience sensory symptoms called auras accompanying the headaches. Cortical spreading depression (CSD), a slow-propagating wave of neuroglial depolarization followed by hyperpolarization is proposed to be the neurological mechanism underlying these auras. We have previously found that progesterone regulates susceptibility to migraine through progesterone receptor (PR) activation.

Emerging evidence suggests the serine protease, urokinase plasminogen activator (uPA), may play an important role in the modulation of mood and cognitive functions. Also, preliminary evidence indicates that uPA modulates BDNF activity that is known to be involved in the pathogenesis of mood disorders. However, the physiological functions of uPA in specific brain regions for mediating stress-related emotional behaviors remain to be elucidated.
