    • Activation of RANKL-induced osteoclasts and memory T lymphocytes by Porphyromonas gingivalis is serotype dependant 
      Vernal Astudillo, Rolando; Díaz Zúñiga, Jaime; Melgar Rodríguez, Samanta; Pujol, Myriam; Díaz Guerra, Eva; Silva, Augusto; Sanz, Mariano; García Sanz, José (Blackwell Munksgaard, 2014)
      Aim: Destructive periodontitis is associated with a Th1–Th17 immune response and activation of RANKL-induced osteoclasts. In addition, Porphyromonas gingivalis K1 and K2 serotypes induce a strong Th1–Th17 response. This ...
    • 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 ...
    • Gingival crevicular fluid as biomarker’s source for Alzheimer’s disease 
      Sansores España, Luis; Morales Lara, Francisca; Arriola Pacheco, Fabio; Astorga, Jessica; Paula Lima, Andrea; Carrillo Ávila, Arelly; Melgar Rodríguez, Samanta; Martínez Aguilar, Víctor; Díaz Zúñiga, Jaime (Universidad Costa Rica, Facultad Odontología, 2022)
      Periodontitis is a low-grade inflammatory disease caused by a subgingival dysbiotic microbiota. Multiple studies have determined the higher prevalence of tooth loss and poor oral hygiene in patients with Alzheimer's disease ...
    • Serotype a of Aggregatibacter actinomycetemcomitans down-regulates the increased serotype b-induced cytokine ... 
      Rojas, Leticia; Melgar Rodríguez, Samanta; Díaz Zúñiga, Jaime; Alvarez, Carla; Monasterio, Gustavo; Rojas, Carolina; Carvajal, Paola; Vernal Astudillo, Rolando (Elsevier Ltd, 2018)
      Objective: In Aggregatibacter actinomycetemcomitans, different serotypes have been described based on LPS antigenicity. Mixed infection with the different A. actinomycetemcomitans serotypes is frequent in periodontitis ...
    • 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 ...
