Gamonal Aravena, Jorge Antonio; Bascones, A.; Acevedo, A.; Blanco, E.; Silva, A. (American Academy of Periodontology, 2001-04)Background: Apoptosis is an evolutionary form of physiological cell death. Previous studies suggest that apoptosis is involved in the pathogenesis of periodontal diseases. Therefore, we studied the apoptotic events in the ...

Gamonal Aravena, Jorge Antonio; Acevedo, A.; Bascones, A.; Jorge, O.; Silva, A. (Munksgaard, 2001-06)Leukocyte migration is essential for immune surveillance of tissues by focusing immune cells to sites of antigenic challenge. The control of leukocyte migration depends on the combined actions of adhesion molecules and a ...

Gamonal Aravena, Jorge Antonio; Bascones, A.; Jorge, O.; Silva, A. (Munksgaard, 2000-09)Background, aims: This study presents the first evidence on the presence of the chemokine RANTES in the gingival fluid crevicular (GCF) of patients with periodontitis. RANTES is a chemokine that selectively attracts and ...

Gamonal Aravena, Jorge Antonio; Sanz, M.; O'Connor, A.; Acevedo, A.; Suarez, I.; Sanz, A.; Martínez, B.; Silva, A. (Blacwell Munksgaard, 2003-07)Background, aims: Neutrophil cells constitute the first defense barrier against the oral bacterial challenge in the periodontium. Reduction of neutrophils could impair this response against periopathogenic bacteria such ...

Gamonal Aravena, Jorge Antonio; Acevedo, A.; Bascones, A.; Jorge, O.; Silva, A. (American Academy of Periodontology, 2000-10)Background: Various cytokines have been identified at sites of chronic inflammation such as periodontitis. Cytokines are synthesized in response to bacteria and their products, inducing and maintaining an inflammatory ...

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 ...
