    • ABCB1 C1236T, G2677T/A and C3435T polymorphisms in systemic lupus erythematosus patients 

      Gonzalez, Tatiana Pereira; Mucenic, Tamara; Brenol, João Carlos Tavares; Xavier, Ricardo Machado; Schiengold, Marion; Chies, Jose Artur Bogo (2008) [Artículo de periódico]
      P-glycoprotein (Pgp), the ABCB1 gene product, acts as an efflux pump that transports a large variety of substrates and is a mechanism of cell protection against xenobiotics. An increasing number of studies have shown that ...

    • Características de atividade das células natural killer em pacientes com esclerose sistêmica 

      Salim, Patrícia Hartstein; Wilson, Mariana de Sampaio Leite Jobim; Bredemeier, Markus; Chies, Jose Artur Bogo; Brenol, João Carlos Tavares; Jobim, Luiz Fernando Job; Xavier, Ricardo Machado (2013) [Artículo de periódico]
      Estudos têm relatado um aumento da expressão das células natural killer (NK) no sangue periférico de pacientes com esclerose sistêmica (ES). Essas células fazem parte da imunidade inata, reconhecendo células infectadas por ...

    • Combined effects of CXCL8 and CXCR2 gene polymorphisms on susceptibility to systemic sclerosis 

      Salim, Patrícia Hartstein; Wilson, Mariana de Sampaio Leite Jobim; Bredemeier, Markus; Chies, Jose Artur Bogo; Brenol, João Carlos Tavares; Jobim, Luiz Fernando Job; Xavier, Ricardo Machado (2012) [Artículo de periódico]
      A previous study suggested that the CXCR2 (+1208) TT genotype was associated with increased risk of systemic sclerosis (SSc). In the present study, we investigated the influence of variation in the CXCL8 and CXCR2 genes ...

    • Fasciola hepatica extract suppresses fibroblast-like synoviocytes in vitro and alleviates experimental arthritis 

      Dalmolin, Suelen Pizzolatto; Pedó, Renata Ternus; Rosa, Thales Hein da; Silva, Jordana Miranda de Souza; Farinon, Mirian; Vieira, Maria Luísa Gasparini; Chiela, Eduardo Cremonese Filippi; Paz, Ana Helena da Rosa; Sehabiague, Martín Pablo Cancela; Ferreira, Henrique Bunselmeyer; Espírito Santo, Rafaela Cavalheiro do; Gonçalves, Fabiany da Costa; Xavier, Ricardo Machado (2022) [Artículo de periódico]
      Background: Rheumatoid arthritis (RA) is a chronic infammatory disease characterized by synovial infammation, fbroblast-like synoviocytes (FLS) activation and joint destruction. Fasciola hepatica is a platyhelminth that ...

    • Matrix metalloproteinase gene polymorphisms and susceptibility to systemic sclerosis 

      Rech, Tássia Flores; Moraes, Sara Beatriz del Cueto; Bredemeier, Markus; Paoli, Juliana de; Brenol, João Carlos Tavares; Xavier, Ricardo Machado; Chies, Jose Artur Bogo; Simon, Daniel (2016) [Artículo de periódico]
      The major pathological hallmark of the systemic sclerosis (SSc) is skin and internal organ fibrosis, which results from normal tissue architecture alterations and extracellular matrix (ECM) protein deposition. ECM components ...

    • MBL2 gene polymorphisms and its relation to infection in Brazilian systemic lupus erythematosus patients : a 10-years followup study 

      Saldanha, Carla Forgiarini; Lawisch, Gabriela Kniphoff da Silva; Glesse, Nadine; Brenol, João Carlos Tavares; Xavier, Ricardo Machado; Chies, Jose Artur Bogo; Monticielo, Odirlei André (2022) [Artículo de periódico]
      Introduction: Systemic lupus erythematosus (SLE) is a multifactorial disease and MBL2 genetic variants, which are associated to differential peripheral MBL levels, potentially affect its etiology and increase infection ...

    • O papel do gene e da molécula HLA-G na expressão clínica das doenças reumatológicas 

      Brenol, Claiton Viegas; Veit, Tiago Degani; Chies, Jose Artur Bogo; Xavier, Ricardo Machado (2012) [Artículo de periódico]
      O antígeno leucocitário humano G (HLA-G) é uma molécula não clássica de complexo principal de histocompatibilidade (MHC) de classe I, caracterizada por baixo polimorfismo em sua região codificadora, um padrão de distribuição ...

    • Prolactina, estradiol e anticorpos anticardiolipina em amostra de mulheres pré-menopáusicas com lúpus eritematoso sistêmico : estudo-piloto
