Exosomal long non-coding RNAs in glioblastoma.

Glioblastoma multiforme (GBM) is the most prevalent primary tumor found in the central nervous system, accounting for 70% of all adult brain tumors. The median overall survival rate is one year post-diagnosis with treatment, and only four months without treatment. Current GBM diagnostic methods, such as magnetic resonance imaging (MRI), surgery, and brain biopsies, have limitations.

Effective Reduction of Tau Amyloid Aggregates in the Presence of Cyclophilin from Pollens; An Alternative Mechanism of Action of the Allergen.

Background: A hallmark pathology of Alzheimer's disease (AD) is the construction of neurofibrillary tangles, which are made of hyperphosphorylated Tau. The cis-proline isomer of the pThr/Ser-Pro sequence has been suggested to act as an aggregation precursor according to the 'Cistauosis' hypothesis; however, this aggregation scheme is not yet completely approved. Various peptidyl-prolyl isomerases (PPIases) may specifically isomerize cis/trans-proline bonds and restitute Tau's ability to attach microtubules and may control Tau amyloid aggregation in AD.

Sunset yellow degradation product, as an efficient water-soluble inducer, accelerates 1N4R Tau amyloid oligomerization: In vitro preliminary evidence against the food colorant safety in terms of "Triggered Amyloid Aggregation".

Today, Alzheimer's disease (AD) as the most prevalent type of dementia turns into one of the most severe health problems. Neurofibrillary tangle (NFT), mostly comprised of fibrils formed by Tau, is a hallmark of a class of neurodegenerative diseases. Tau protein promotes assembly and makes stable microtubules that play a role in the appropriate function of neurons.
