Which pathologic importance do tau oligomeres have?
Immovable aggregations of the microtubule-associated Tau characterise a number of neurological degenerative disorders known as thaw. They consist of abnormal hypophosphorylated and malfolded tau proteina. The research in this domain has historically concentrated on how hypophosphorylated and aggregate tau mediate tau dysfunctions and toxicities in the case of thaw. Latest results from both Drosophila and rodents indicate that large indissoluble aggregations such as taufilament and confusion may not be the most important of these disease types.
Some researchers have therefore moved their research to the investigation of prefilamentary Tau types such as Tau oligo-compounds and hyper-phosphorylated Tau monomer. It is interesting to note that tau oligooms can occur in a wide range of states, as well as hyper-phosphorylated and non-phosphorylated shapes, which can be either dissolvable or not. This will be important to better understanding so that tau-based therapeutical intervention can be targeted at the most poisonous tau sorts.

Serine-409 Phosphoryylation and oxidative harm define the accumulation of humans tau proteins in lees - Vanhelmont - 2010 - FEMS Research
Winderickx, Laboratory of Functional Biology, Catholic University of Leuven, Schlosspark Arenberg 31, 3001 Heverlee, Leuven, Belgium. Kathleen Lemaire, Katholieke Universiteit Leuven, Afd. The elucidation of the biologic and genetical changes that regulate the accumulation of tau is critical to the understanding of the tau-related neurological dysgeneration aetiology. WILDTYPE and six fronto-temporal chromosomal dementias with Parkinson' s disease (FTDP) mutant mutations of tau in WILDTYPE and WILDTYPE cell without Mds1 or Pho85, the orthologists of the tau kinase GSK3? and GSK3CC5.
The tau sulfurylation was measured against the content of sarcosyl insoluble tau (SinT) as a measurement of tau-aggregations. Pho85 deficiency significantly increased the serine-409 (S409) in all Tau serine matants, resulting in a significant increase in SinT-values. tau-P301L and tau-R406W were the least phosphorylated in S409 and produce the lower SinT values, suggesting that S409 phosphorylation is a primary factor for Tau accumulation.
These findings were confirmed by the tau-S409A synthesized mother, which did not generate significant quantities of SinT, while its tau-S409E coated tau with pseudophosphorylation produced higher SinT values than or similar to wild-type Tau. In addition, S409-phosphoryylation reduces the tau bond to pre-formed microtubuli. Highest SinT values were found in lymphocytes with oxidation stresses and witchondrial dysfunctions.
In these circumstances, the accumulation of dew was improved, although the phosphorylation of the proteins is lower, indicating that extra mechanism is at work. The results of our work validated leaven as the main tool for identifying the genetics and biochemistry contributing to the physiology of hominid dew.
