Leishmania infantum induces high phagocytic capacity and intracellular nitric oxide production by human proinflammatory monocyte

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The mechanism of resistance to SbIII in Leishmania is complex, multifactorial and involves not only biochemical mechanisms, but also other elements, such as the immune system of the host. OBJECTIVES In this study, putative changes in the immunological profile of human monocytes infected wit...

Intracellular reactive oxygen species production and phagocytosis of Staphylococcus aureus by milk neutrophils as tool to diagnose mastitis and identify susceptible dairy cows

Pesqui. vet. bras; 38 (4), 2018
The immune response capacity of the mammary gland plays a major role to determine if mastitis will or not be established. Thus, we hypothesize that a better understanding of polymorphonuclear neutrophil leukocyte (PMN) function will elucidate mechanisms that will improve our knowledge of how we could avo...

Estudio funcional de la respuesta inmune a vacunas anti neumocóccicas
Evaluation of functional immune response to pneumococcal vaccines

Rev. chil. infectol; 16 (supl. 1), 1999
Los estudios descritos usan fagocitos cultivables, los cuales ayudan a la estandarización de un ensayo de fagocitos que puede medir repetitivamente la respuesta inmune de anticuerpos funcionales. La opsonofagocitosis parece ser un sustituto apropiado de la protección in vivo, ya que muestra una buena c...

Quantificaçäo da interferência do soro na fagocitose de imunocomplexos nas espondiloartropatias soronegativas, lúpus eritematoso sistêmico e doença reumatóide
Quantification of serum interference in the immune complexes phagocytosis in seronegative spondylarthropaties, systemic lupus erythematosus and rheumatoid disease

Cinqüenta e cinco soros de pacientes portadores de espondiloartropatias soronegativas, lúpus eritematoso sistêmico e artrite reumatóide foram selecionados para o estudo. Todos os soros mostravam fator reumatóide negativo pela prova de látex. A determinaçäo da interferência na fagocitose de gamag...

Resposta do hospedeiro à infecçäo: inativaçäo de mediadores e morte do agressor
Host reatios to infection: bacterial inactivation and villing

Arq. bras. med; 65 (5), 1991
A emigraçäo do leucócito até o local de agressäo subseqüente às adaptaçöes físico-químicas do tecido inflamatório que permitem os processos de marginaçäo, aderência endotelial, permeabilidade vascular e diapedese. A movimentaçäo extravascular do leucócito no sentido do agressor é orien...
