    • Alveolar bone resorption and TH1/TH17-associated immune response triggered during Aggregatibacter ... 
      Monasterio, Gustavo; Castillo, Francisca; Ibarra, Juan; Guevara, José; Rojas, Leticia; Alvarez, Carla; Fernández, Baltasar; Agüero, Amaru; Betancur, Daniel; Vernal Astudillo, Rolando (Wiley-Blackwell, 2018)
      BACKGROUND: Aggregatibacter actinomycetemcomitans expresses several virulence factors that may contribute to the pathogenesis of periodontitis. Based on the antigenicity of the O-polysaccharide component of the ...
    • Differential expression of CC chemokines (CCLs) and receptors (CCRs) by human T lymphocytes in response to ... 
      Alvarez Rivas, Carla; Benítez Cravero, Alvaro; Rojas, Leticia; Pujol, Myriam; Carvajal Pavez, Paola; Díaz Zúñiga, Jaime; Vernal Astudillo, Rolando (Univ Sao Paulo Fac Odontologia Bauru, 2015)
      In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on LPS antigenicity. Recently, our research group has reported a differential immunogenicity when T lymphocytes were stimulated with ...
    • Differential human Th22-lymphocyte response triggered by Aggregatibacter actinomycetemcomitans serotypes 
      Díaz Zúñiga, Jaime; Melgar Rodríguez, Samanta; Monasterio, Gustavo; Pujol, Myriam; Rojas, Leticia; Alvarez, Carla; Carvajal, Paola; Vernal Astudillo, Rolando (Elsevier Ltd, 2017)
      Objective: In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on lipopolysaccharide (LPS) antigenicity. When T lymphocytes were stimulated with these serotypes, different patterns of ...
    • Immunostimulatory activity of low-molecular-weight hyaluronan on dendritic cells stimulated with Aggregatibacter ... 
      Monasterio, Gustavo; Guevara, José; Ibarra, Juan; Castillo, Francisca; Díaz Zúñiga, Jaime; Alvarez, Carla; Cafferata, Emilio; Vernal Astudillo, Rolando (Springer Verlag, 2018)
      Objectives Periodontitis is a chronic inflammatory disease characterized by tooth-supporting tissue destruction, which is elicited by the host’s immune response triggered against periodonto-pathogen bacteria. During ...
    • O-polysaccharide plays a major role on the virulence and immunostimulatory potential of aggregatibacter ... 
      Monasterio, Gustavo; Ormeño Castillo, Francisca; Astorga, Jéssica; Hoare Teuche, Anilei; Terraza, Claudia; Cafferata, Emilio A.; Villablanca, Eduardo J.; Vernal Astudillo, Rolando Marcelo (Frontiers Media, 2020)
      Aggregatibacter actinomycetemcomitans is a Gram-negative oral bacterium with high immunostimulatory and pathogenic potential involved in the onset and progression of periodontitis, a chronic disease characterized by aberrant ...
    • Serotype-dependent response of human dendritic cells stimulated with Aggregatibacter actinomycetemcomitans 
      Díaz Zúñiga, Jaime; Yáñez Figueroa, Juan Pablo; Álvarez, Carla; Melgar Rodríguez, Samanta; Hernández Ríos, Emma; Sanz, Mariano; Vernal Astudillo, Rolando (2014)
      Aim: Different serotypes of Aggregatibacter actinomycetemcomitans have been described based on the lipopolysaccharide (LPS)-O-polysaccharide antigenicity. In turn, a distinct effect of A. actinomycetemcomitans serotypes ...
    • Variability of the dendritic cell response triggered by different serotypes of Aggregatibacter actinomyce ... 
      Díaz Zúñiga, Jaime; Monasterio, Gustavo; Álvarez, Carla; Melgar Rodríguez, Samanta; Benítez, Álvaro; Ciuchi, Pía; García, Matías; Arias, Jocelyn; Sanz, Mariano; Vernal Astudillo, Rolando (American Academy of Periodontology, 2015)
      Background: Different serotypes of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis have been shown to induce differential dendritic cell (DC) responses. This study investigates whether cytokine and ...
