Le neutrophile : ennemi ou ami ?

Abstract: Les polynucléaires neutrophiles (PN) sont des agents de premier plan de l'immunité innée, particulièrement lors de la réaction inflammatoire ; ils sont souvent les premiers leucocytes à migrer en grand nombre vers le site enflammé. La réaction inflammatoire est le plus souvent protectrice car elle participe à la défense naturelle de l'organisme et à la réparation des tissus lésés. Malheureusement, si elle est inadaptée ou mal régulée, l'inflammation peut devenir nocive. Ainsi le neutrophile est mis en cause da… Show more

“…It is well-established that neutrophils undergo phenotypic, functional, and morphological changes in the circulatory system several hours after sepsis onset, and the upregulation of PD-L1 expression may play a key role in this process ( Figure 2 ) ( 74 , 79 82 ). Under physiological conditions, neutrophils eliminate pathogenic microorganisms through adhesion, migration, phagocytosis, and respiratory eruption ( 83 ). However, in sepsis, neutrophils have abnormal mobilization, delayed apoptosis, migration dysfunction, phagocytosis dysfunction, and other abnormal manifestation ( 84 88 ).…”

“…Ils libèrent également des enzymes et des facteurs oxydants afin d'optimiser leur capacité de clairance du tissu lésé [11] (➜). Ainsi, dans un modèle de blessure musculaire induite par une toxine ou une infection, la suppression des neutrophiles entraîne la persistance des fibres nécrotiques [12].…”

“…Recently, there have been intriguing attempts at identifying endogenous agents with particularly active roles in resolution of inflammation. Thus, there is focus on pro-resolution effects of IL-10 and TGF-beta, adenosine and prostaglandin D2, lipoxins and other lipid mediators [1,33-35]. Some of these regulatory molecules may live up to the actual meaning of the now almost obsolete name 'autacoids' (self remedy).…”

“…Some of these regulatory molecules may live up to the actual meaning of the now almost obsolete name 'autacoids' (self remedy). Important roles of certain cells and cell phenotypes in resolution are also entertained with focus on regulatory T cells, macrophages, and neutrophils [1,35]. In addition, select transcription factors [36] and post-transcriptional regulons [37] are given roles in resolution of inflammation.…”
