    • Levels of interleukin-17 in gingival crevicular fluid and in supernatants of cellular cultures of gingival ... 
      Vernal Astudillo, Rolando; Dutzan Muñoz, Nicolás; Chaparro, Alejandra; Puente Piccardo, Javier; Valenzuela, María Antonieta; Gamonal Aravena, Jorge Antonio (BLACKWELL MUNKSGAARD, 2005-04)
      Background and Aims: Interleukin-17 (IL-17) is a T-cell-derived cytokine that may play an important role in the initiation or maintenance of the pro-inflammatory response and has recently been found to stimulate osteoclastic ...
    • Matrix metalloproteinase-13 is highly expressed in destructive periodontal disease activity 
      Hernández Ríos, Emma; Valenzuela, María Antonieta; López Otin, Carlos; Alvarez, Jesús; López, José Manuel; Vernal Astudillo, Rolando; Gamonal Aravena, Jorge Antonio (American Academy of Periodontology, 2006-11)
      Background: Matrix metalloproteinases (MMPs) participate in extracellular matrix degradation in physiological and pathological conditions. The available evidence suggests that MMP-13 plays a significant role in both the ...
    • MMP-13 and TIMP-1 determinations in progressive chronic periodontitis 
      Hernández Ríos, Emma; Martínez, Benjamín; Tejerina, José María; Valenzuela, María Antonieta; Gamonal Aravena, Jorge Antonio (2007)
      Matrix metalloproteinase (MMP)-13 is a collagenase involved in extracellular matrix degradation either by its direct degradative effects or by processing bioactive substrates. The aim of this study was to determine the ...
    • Proteolytic roles of matrix metalloproteinase (MMP)-13 during progression of chronic periodontitis: initial ... 
      Hernández Ríos, Emma; Sorsa, Timo; Obregón, Fabián; Tervahartiala, Taina; Valenzuela, María Antonieta; Pozo, Patricia; Dutzan Muñoz, Nicolás; Lesaffre, Emmanuel; Molas, Marek; Gamonal Aravena, Jorge Antonio (European Federation of Periodontology, 2009-12)
      Aim: Matrix metalloproteinases (MMP)-13 can initiate bone resorption and activate proMMP-9 in vitro, and both these MMPs have been widely implicated in tissue destruction associated with chronic periodontitis. We studied ...
    • Stimulatory response of neutrophils from periodontitis patients with periodontal pathogens 
      Restaino Bianchi, Carmen Gloria; Chaparro, Alejandra; Valenzuela, María Antonieta; Kettlun, Ana María; Vernal Astudillo, Rolando; Silva, A.; Puente Piccardo, Javier; Jaque, M. P.; León Berríos, Rubén; Gamonal Aravena, Jorge Antonio (2007)
      OBJECTIVE: Neutrophils play a crucial role in the defense of invading bacteria by releasing biologically active molecules. The response of peripheral blood neutrophils was studied in periodontitis-affected patients and in ...
