Creatine, central nervous system and creatine deficiency syndromes

It was long thought that most of brain creatine was of peripheral origin. However, recentworks have demonstrated that creatine crosses blood-brain barrier only with poor efficiency, and thatCNS must ensure parts of its creatine needs by its own creatine synthesis pathway, thank to the brainexpression of AGAT and GAMT (creatine synthesis) and SLC6A8 (creatine transporter). This newunderstanding of creatine metabolism and transport in CNS allows a better comprehension of creatinedeficiency syndromes, which are due to deficiencies in AGAT, GAMT and SLC6A8 and mainly affectthe brain of patients who show severe neurodevelopmental delay and present neurological symptomsin early infancy.

Effect of Dexamethasone on cytolkine secretion in CD4+T cells in steroid refractori uveitis

Projecte de recerca elaborat a partir d’una estada a la facultat de Medical Sciences de la Universitat de Bristol, Alemanya, entre 2011 i 2012. Aquest treball s'ha realitzat a la facultat de Medical Sciences de la Universitat de Bristol, al laboratori del Prof. Andrew Di cks,o ta la seva supe1visi6. Ei treball s'ha realitzat amb els seus col.laboradors, el Dr Richard Lee i Lauren Schew:tz. Objectiu: Els glucocorticoids (GCs) tenen diversos efectes sobre les cèl.lules T CD4+ per modular la resposta immune principalment mitjançant els seus efectes anti-proliferatius. Tot i això la dexametasona (Dex, glucocorticoid sintètic) també indueix la secreció de la citocina immunosupressora IL-10 . L'objectiu d'aquest treball ha estat comparar la capacitat dels glucocorticoids en modular la producció de citocines en cèl.lules T CD4+ en pacients uveítics sensibles (SS), i resistents (SR) a esteroids. Metodologia: Es van aïllar cèl• lules T CD4+ de pacients uveítics SS i SR. Es va induir la producció de cèl.lules T regulatories (Tregs) i mitjançant I'estimulació amb anti- CD3/CD28 en presència d'lL-2 i Després del cultiu es van analitzar els nivells d’expressió intracel•lular de les citocines IL-10, IL-4, IL-9, IL-17 i IFN-y per citometria de flux. D'altra banda, també es van separar cèl.lules T CD4t de pacients uveïtis segons I'expressió de CCR6 i es van polaritzar per obtenir els fenotips ThO i Th17 per estudiar I'efecte de Dex i ciclosporina (CsA) en aquests subtipus cel.lulars. Resultats: Les cèl.lules T CD4+ de pacients SR no van ser capaces de produir IL-10 en resposta al tractament amb Dex. Dex no va afectar els nivells d'expressió d'11-17, però va reduir els nivells de IL-4 i IFN-V. Els nivells d'lL-9 (marcador d'un subtipus cel.lular recentment descrit, Th9) v ise r sempre inferiors a 11%. En canvi, el traclament a amb CsA va reduir significativament els nivells d'lL-17 i IFN-y en cèl.lules Th17 i ThO. Conclusions: La Dex no és capaç d'induir cèl.lules Treg funcionalment supresores en pacients veiticsS R. Aquest fenòmen és Independent dels efectes en I'expressió d'altres citocines. Aquests resultats suggereixen que I'efecte de la Dex sobre la funció de cél.lules Treg és clau en el desenvolupament del fenotip SR en la uveïtis . D'altra banda, al llarg d'aquest temps he iniciat un nou projecte que ha donat lloc a un futur projecte de col elaboració. Resumidament, degut a que els nivells elevats de proteïna C-reactiva (CRP) són un factor de risc en la degeneració macular, malaltia inflamatòria crònica principal causa de ceguera en països industrialitzats, I'objectiu d'aquest altre treball ha estat iniciar un projecte per avaluar els efectes de les diferents isoformes de la CRP sobre la resposta inflamatòria d’epiteli pigmentari retinià.

Repercussion of a deficiency in mitochondrial ß-oxidation on the carbon flux of short-chain fatty acids to the peroxisomal ß-oxidation cycle in Aspergillus nidulans.

The fungus Aspergillus nidulans contains both a mitochondrial and peroxisomal ß-oxidation pathway. This work was aimed at studying the influence of mutations in the foxA gene, encoding a peroxisomal multifunctional protein, or in the scdA/echA genes, encoding a mitochondrial short-chain dehydrogenase and an enoyl-CoA hydratase, respectively, on the carbon flux to the peroxisomal ß-oxidation pathway. A. nidulans transformed with a peroxisomal polyhydroxyalkanoate (PHA) synthase produced PHA from the polymerization of 3-hydroxyacyl-CoA intermediates derived from the peroxisomal ß-oxidation of external fatty acids. PHA produced from erucic acid or heptadecanoic acid contained a broad spectrum of monomers, ranging from 5 to 14 carbons, revealing that the peroxisomal ß-oxidation cycle can handle both long and short-chain intermediates. While the ∆foxA mutant grown on erucic acid or oleic acid synthesized 10-fold less PHA compared to wild type, the same mutant grown on octanoic acid or heptanoic acid produced 3- to 6-fold more PHA. Thus, while FoxA has an important contribution to the degradation of long-chain fatty acids, the flux of short-chain fatty acids to peroxisomal ß-oxidation is actually enhanced in its absence. While no change in PHA was observed in the ∆scdA∆echA mutant grown on erucic acid or oleic acid compared to wild type, there was a 2- to 4-fold increased synthesis of PHA in ∆scdA∆echA cells grown in octanoic acid or heptanoic acid. These results reveal that a compensatory mechanism exists in A. nidulans that increases the flux of short-chain fatty acids towards the peroxisomal ß-oxidation cycle when the mitochondrial ß-oxidation pathway is defective.

Islands of euchromatin-like sequence and expressed polymorphic sequences within the short arm of human chromosome 21

The goals of the human genome project did not include sequencing of the heterochromatic regions. We describe here an initial sequence of 1.1 Mb of the short arm of human chromosome 21 (HSA21p), estimated to be 10% of 21p. This region contains extensive euchromatic-like sequence and includes on average one transcript every 100 kb. These transcripts show multiple inter- and intrachromosomal copies, and extensive copy number and sequence variability. The sequencing of the "heterochromatic" regions of the human genome is likely to reveal many additional functional elements and provide important evolutionary information.

Meeting highlights of the 8th Annual Scientific Sessions of the Society For Cardiovascular Magnetic Resonance, January 21 to 23, 2005.

Parallel tracks for clinical scientists, basic scientists, and pediatric imagers was the novel approach taken for the highly successful 8th Annual Scientific Sessions of the Society for Cardiovascular Magnetic Resonance, held in San Francisco, California, January 21 to 23, 2005. Attendees were immersed in information on the latest scientific advances in cardiovascular magnetic resonance (CMR) from mice to man and technological advances from systems with field strengths from 0.5 T to 11.7 T. State-of-the-art applications were reviewed, spanning a wide range from molecular imaging to predicting outcome with CMR in large patient populations.
