Structural dynamics and catalytic modulations of Aβ regulating enzymes as future outlook for Alzheimer's.

Aβ cascade hypothesis being considered most evident event in AD pathology and even today it holds good. Dysregulation of catalytic events of Aβ regulating enzymes can possibly cause faulty Aβ trafficking; inequity of Aβ formation and clearance resulting in misfolded protein accumulation, neurodegeneration and cognitive impairment. Many novel approaches have been made on this pathway to discover new molecules, unfortunately couldn't reach the terminal phases of clinical trials.

Neuronal PET tracers for Alzheimer's disease.

Advancements in brain imaging techniques have emerged as a significant tool in detecting Alzheimer's disease (AD) progression. The complicated cascade of AD progression can be detected using radio imaging, especially with Positron emission tomography (PET). The review focus on recently introduced investigational PET tracers targeting neurofibrillary tau aggregates found typically in AD.

Glitazones, PPAR-γ and Neuroprotection.

The transcriptional factor PPAR-γ belongs to the nuclear receptor family, which has become a potential therapeutic target for several neurodegenerative diseases and metabolic disorders. Interestingly, PPAR-γ has been reported to have beneficial effects in various chronic neurological conditions via upregulation of its transcriptional co-activator PGC-1α and followed by regulation of multiple molecular events. Although several factors contribute to the progression of neurodegeneration, the dysfunction of PGC-1α expression is primarily interlinked with the pathogenesis of major neurodegenerative diseases.

Minutes of PPAR-γ agonism and neuroprotection.

Peroxisome proliferator-activated receptor gamma (PPAR-γ) is one of the ligand-activated transcription factors which regulates a number of central events and considered as a promising target for various neurodegenerative disease conditions. Numerous reports implicate that PPAR-γ agonists have shown neuroprotective effects by regulating genes transcription associated with the pathogenesis of neurodegeneration. In regards, this review critically appraises the recent knowledge of PPAR-γ receptors in neuroprotection in order to hypothesize potential neuroprotective mechanism of PPAR-γ agonism in chronic neurological conditions.
