  NÚCLEO DE EXCELÊNCIA EM BIOQUÍMICA, BIOLOGIA ESTRUTURAL E MOLECULAR E SIMULAÇÃO MOLECULAR DE PROTEÍNAS (NATIVAS E RECOMBINANTES) DE ESPÉCIES VEGETAIS DO CARIRI COM POTENCIAL INFLAMATÓRIO, Projeto certificado pelo(a) coordenador(a) Benildo Sousa Cavada em 22/08/2016., Descrição: A presente proposta, Núcleo de excelência em bioquímica, biologia estrutural e molecular e simulação molecular de proteínas (nativas e recombinantes) de espécies vegetais do Cariri com potencial inflamatório, tem a peculiaridade de lançar desafios em interfaces (bioquímica, farmacologia e a física, passando por recursos de informática específicos) que abrem novas fronteiras e geram novos desafios. O Ceará tem uma longa tradição no estudo de biomoléculas advindas da sua biodiversidade, quer no isolamento dessas moléculas, quer no estudo farmacológico das mesmas. Por outro lado, o Ceará possui uma massa crítica reconhecida nacional e internacionalmente, fundamentada num dos melhores Programas de Pós- graduação na área de Física no Norte/Nordeste do Brasil. Desta forma, esta proposta se destina tanto a avançar numa interação consolidada como em aprofundar novas fronteiras do conhecimento. Por um lado, esse projeto visa prospectar e aprofundar o estudo de moléculas biologicamente ativas de recursos naturais de nossa flora, em especial de espécies nativas e endêmicas do Cariri. Neste cenário, o presente estudo irá focar em um grupo específico de proteínas, as lectinas, definidas como moléculas que possuem pelo menos um domínio de ligação específica e reversível a carboidratos, característica que permite uma grande variabilidade de aplicações biológicas. Desta forma, pretende-se, a partir do desenvolvimento desta proposta, detectar, isolar, purificar e caracterizar (físico química e estruturalmente) novas lectinas de espécies nativas da região do Cariri e produzir algumas delas na forma recombinante a partir de seus respectivos genes, avaliar os efeitos destas lectinas sobre os aspectos fisiopatológicos da inflamação. Assim, algumas das lectinas purificadas serão testadas em processos inflamatórios, em nocicepção inerente a inflamação e em disfunção endotelial induzidas por processos inflamatórios. Além disto, algumas destas moléculas serão selecionadas, levando-se em conta seus potenciais de atividades relacionadas à inflamação, e destinadas a estudos estruturais utilizando ferramentas teóricas e experimentais para investigar fatores que influenciem a ligação das lectinas à seus ligantes específicos. Isso será realizado através de simulações, modelagens moleculares e cálculo ab initio de química quântica para determinar os potenciais de interação entre lectinas e alguns de seus ligantes específicos,. A interação de átomos quimicamente ligados é usualmente representada por molas virtuais e ângulos entre ligações, que variam no tempo e representam vibrações moleculares e torções das ligações. Também serão utilizados, em algumas situações, métodos de dinâmica molecular para determinar os fatores que contribuem para a ligação proteína-ligante (lectina-glicoconjugado). Os resultados serão comparados a dados experimentais de atividades de cada proteína. Sempre que possível, ou necessário, abordagens de simulações moleculares entre lectinas e ligantes serão utilizadas. Por outro lado, a proposta pretende nuclear um novo grupo na região sul do Estado do Ceará, favorecendo a interiorização de uma forma interdisciplinar da pesquisa científica, envolvendo professores lotados também em Instituição de Ensino Superior no interior, como a Universidade Federal do Cariri. Toda essa proposta está, implicitamente, fundamentada em uma forte política de formação de recursos humanos através dos Programas de Pós-graduação que envolvem os pesquisadores da mesma.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (6) / Mestrado acadêmico: (6) / Doutorado: (4) . , Integrantes: Gil de Aquino Farias - Integrante / Jeanlex S de Sousa - Integrante / B.

  Auto-organização, propriedades eletrônicas e processos dinâmicos em sistemas de baixa dimensionalidade, Descrição: (Projeto de cooperação bilateral Brasil-Bélgica (CNPq-FWO)) Sistemas compostos por um grande número de agentes interatuantes apresentam comportamento complexo o qual pode atualmente ser abordado, em muitos aspectos, de maneira bastante precisa através de métodos de física teórica e computacional. Grande parte do complexo comportamento do sistema é conseqüência da correlação entre seus muitos componentes, fato que gera propriedades físicas não-triviais. O grande avanço na capacidade dos computadores observado na última década promoveu também avanços em softwares, motivando físicos teóricos a estudar problemas fundamentais complexos que surgiram na pesquisa de ponta em física experimental. Do lado experimental, observa-se também um grande avanço na produção e desenvolvimento de materiais compósitos auto-organizados, de diferentes tamanhos e formas, com dimensões nas escalas micro- e nano-métrica. Esses diferentes sistemas físicos são objetos de intensa atividade científica devido suas novas e marcantes caracterísitcas, com grande potencial de aplicabilidade em diversos campos, que vão desde ciência físicas básica, passando por aplicações em ciências de materiais, biotecnologia e até medicina. É interessante também notar que uma visão bastante geral de pesquisas recentes revela muitos aspectos comuns em sistemas aparentemente não-correlacionados, de modo a motivar um grande esforço científico no entendimento, tanto do ponto de vista fundamental, quanto de aplicação, de tais sistemas. Outro aspecto relevante é a análise de processos dinâmicos que englobam um grande número de agentes interatuantes, ou ainda fenômenos de transporte através de substratos reticulados regulares ou desordenados. Estes são apectos importantes de sistemas de muitos corpos, onde, somente com uma descrição minunciosa de sua topologia, unidades elementares e interações microscópicas, é possível elucidar as diversas e intrincadas nuances de seus comportamentos globais.
