    • Estudiando el papel de los neutrófilos polimorfonucleares en la brucelosis 

      BARQUERO-CALVO, ELIAS (Revista del Colegio de Microbiólogos Químicos Clinicos Costa Rica, 2015-10)
      Las enfermedades infecciosas pueden clasificarse en dos grandes grupos: las agudas y las crónicas. Las bacterias que inducen cuadros crónicos, son en general parásitos intracelulares que tienen tiempos de incubación largos ...

    • Human neutrophils are resistant to Clostridioides difficile toxin B 

      Chaves-Cordero, Catalina; Quesada-Gómez, Carlos; Chaves-Olarte, Esteban; BARQUERO-CALVO, ELIAS (Elsevier, 2022-03-21)
      Objective: The main objective of this study was to evaluate the glucosyltransferase activity of C. difficile TcdB on the activity of human PMNs. Methods: To better understand the interaction between PMNs and TcdB, PMNs ...

    • Neutrophils as Trojan Horse vehicles for Brucella abortus macrophage infection 

      Gutiérrez-Jiménez, Cristina; Mora-Cartín, Ricardo; Altamirano-Silva, Pamela; Chacón-Díaz, Carlos; Chaves-Olarte, Esteban; Moreno, Edgardo; BARQUERO-CALVO, ELIAS (Universidad Nacional, Costa Rica, 2019-05-07)
      Brucella abortus is a stealthy intracellular bacterial pathogen of animals and humans. This bacterium promotes the premature cell death of neutrophils (PMN) and resists the killing action of these leukocytes. B. abortus-infected ...

    • Neutrophils dampen adaptive immunity in Brucellosis 

      Mora-Cartín, Ricardo; Gutiérrez-Jiménez, Cristina; Alfaro-Alarcón, Alejandro; Chaves-Olarte, Esteban; Chacón-Díaz, Carlos; BARQUERO-CALVO, ELIAS; Moreno, Edgardo (American Society For Microbiology, 2019-04-23)
      Brucella organisms are intracellular stealth pathogens of animals and humans. The bacteria overcome the assault of innate immunity at early stages of an infection. Removal of polymorphonuclear neutrophils (PMNs) at the ...

    • The role of neutrophils in Brucellosis 

      BARQUERO-CALVO, ELIAS; Moreno, Edgardo (American Society for Microbiology, 2020-10-14)
      Brucellosis is a bacterial disease of domestic animals and humans. The pathogenic ability of Brucella organisms relies on their stealthy strategy and their capacity to replicate within host cells and to induce long-lasting ...

    • What Is the Evolutionary Fingerprint in Neutrophil Granulocytes? 

      Dolz, Gaby; Fingerhut, Leonie; de Buhr, Nicole (University of Veterinary Medicine Hannover, Hannover, Germany, 2020-06-25)
      Over the years of evolution, thousands of di erent animal species have evolved. All these species require an immune system to defend themselves against invading pathogens. Nevertheless, the immune systems of di erent ...
