1. Phospholipase A2 inhibition and Tau protein phosphorylation in primary cultures of hipocampal neurons / Inibição da fosfolipase A2 e fosforilação da proteína Tau em culturas primárias de neurônios hipocampais
A proteína Tau é um importante componente do citoesqueleto neuronal, encontrada fundamentalmente nos axônios e sendo responsável pela estabilização dos microtúbulos. Agregados de proteína Tau em estado hiperfosforilado dão origem aos filamentos helicoidais pareados, que por sua vez integram os emaranhados neurofibrilares. Estes, ao lado das placas s

2. Esclerose multipla : mediadores da resposta inflamatoria associadas a ressonancia magnetica quantitativa / Quantitative MRI and CSF inflammatory mediators in a sample of brazilian multiple sclerosis population : a prospective study
Quantitative MRI and CSF inflammatory mediators in a sample of brazilian multiple sclerosis population: a prospective study. Multiple sclerosis (MS) is referred to as a chronic inflammatory, demyelinating, and neurodegenerative disorder of the central nervous system (CNS), with a highly variable clinical course and prognosis. This is a prospective study to i

3. Clonagem, expressão e purificação da proteína ligadora de alcano sulfonatos do sistema de transporte ABC de Xanthomonas axonopodis pv.citri. / Cloning, expression and purification of the Xanthomonas axonopodis pv citri ABC transport alkanosulphonate-binding protein.
O genoma de Xanthomonas citri (Xac) possui mais de 20 tipos de transportadores do tipo ABC incluindo o operon ssuABC associado ao transporte de alcano sulfonatos. Deste operon, escolhemos a proteína periplasmática ligadora de alcano sulfonatos SsuA2, para caracterização e análises espectroscópicas e estruturais. A rSsuA2 foi expressa no citoplasma de c

4. Estudos estruturais do domínio GTPase isolado da septina humana SEPT4 e estrutura cristalográfica da Glutationa -S- Transferase de Xylella fastidiosa / Structural Studies of the GTPase domain from human SEPT4 and Crystallography Structure of Glutathione S-transferase from Xylella fastidiosa
The septins are a conserved family of guanine nucleotides-binding and hetero-filament forming. proteins. In mammals they are involved in a variety of cellular processes, such as cytokinesis, exocytosis, and vesicle trafficking. SEPT4 has been reported to accumulate in tau-based filamentous deposits and cytoplasmic inclusions in Alzheimers and Parkinsons dise

5. Aspectos do envelhecimento cerebral e função cognitiva em modelo experimental animal e estudo de mecanismos de neurodegeneração em cultura celular
The two phenomena, biological and behavioural, approached in the present work are brain aging and spatial memory. Several studies, comparative and experimental, have shown that aged subjects present significantly impaired performances in different types of cognitive tasks. It is also known that contradictions in literature exist in relation to consequences o

6. Antiluteolytic activity in the uterine microenvironment during the critic period to pregnancy establishment in bovines / Atividade antiluteolítica no microambiente uterino durante o período crítico para o estabelecimento da gestação em bovinos
The inhibition of pulsatile secretion of PGF2α mediated by interferon-tau (IFN) is fundamental on the maternal recognition of pregnancy, maintaining the progesterone secretion by corpus luteum. Therefore the measurement of interferon activity in the uterine microenvironment was studied. Due to a lack of assays those measure specific antiluteolytic capa

7. The influence of lithium on the risk of Alzheimer s disease / "A influência do lítio no risco para a doença de Alzheimer"
O lítio é freqüentemente utilizado no tratamento do Transtorno Bipolar, doença associada a um risco aumentado para demência. Evidências experimentais sugerem efeitos neuroproterores do lítio. O lítio inibe a amiloidogênese e a fosforilação da proteína tau tanto in vitro como in vivo. Estes são processos importantes na patogênese da doença de A

8. Tau consists of a set of proteins with repeated C-terminal microtubule-binding domains and variable N-terminal domains.
Tau proteins consist of a family of proteins, heterogeneous in size, which associate with microtubules in vivo and are induced during neurite outgrowth. In humans, tau is one of the major components of the pathognomonic neurofibrillary tangles in Alzheimer's disease brain. Screening of a cDNA library prepared from bovine brain led to the isolation of several

9. Modulation of mRNA for microtubule-associated proteins during brain development.
The heterogeneity of tau microtubule-associated proteins from rat brain is developmentally determined. Newborn rat brain contains two tau polypeptides (tau 0) with somewhat different molecular weights than the five tau components associated with microtubules from 12-day-old brain (tau 12). tau 0 and tau 12 are immunologically related and crossreact with anti

10. Recognition of tau epitopes by anti-neurofilament antibodies that bind to Alzheimer neurofibrillary tangles.
Eleven anti-neurofilament (anti-NF) monoclonal antibodies were studied for their reactivity with heat-stable, microtubule-associated proteins and Alzheimer neurofibrillary tangles (ANT). On immunoblots of NF proteins, the antibodies recognized epitopes that were variably sensitive to Escherichia coli alkaline phosphatase. Eight of the antibodies showed react

11. The MAP2/Tau family of microtubule-associated proteins
Microtubule-associated proteins (MAPs) of the MAP2/Tau family include the vertebrate proteins MAP2, MAP4, and Tau and homologs in other animals. They are best known for their microtubule-stabilizing activity roles regulating microtubule networks but, accumulating evidence suggests a much broader range of functions. regulation of microtubule-mediated transpor

12. Structure of the bovine tau gene: alternatively spliced transcripts generate a protein family.
Tau, a major class of microtubule-associated proteins, consists of a family of proteins that are heterogeneous in molecular weight. The presence of internal deletions in previously described cDNA clones for murine and bovine tau suggested that alternative splicing of transcripts could account for the protein size heterogeneity. Analysis of the exon-intron st
