What is Release of neutrophil extracellular traps in response to Candida albicans yeast, as a secondary defense mechanism activated by phagocytosis about?

Candida albicans is one of the main pathogens responsible for the development of difficult-to-fight fungal infections called candidiasis. Neutrophils are the major effector cells involved in the eradication of fungal pathogens. This group of immune cells uses several mechanisms that enable the rapid neutralization of pathogens. The most frequently identified mechanisms are phagocytosis and the release of neutrophil extracellular traps (NETs). The mechanism for selecting the type of neutrophil immune response is still unknown. In our study, we analyzed the relationship between the activation of phagocytosis and netosis. We detected the presence of two neutrophil populations characterized by different response patterns to contact with C. albicans blastospores. The first neutrophil population showed an increased ability to rapidly release NETs without prior internalization of the pathogen. In the second population, the netosis process was inherently associated with phagocytosis. Differences between populations also referred to the production of reactive oxygen species. Our results suggest that neutrophils use different strategies to fight C. albicans and, contrary to previous reports,
