Monocyte-Derived Dendritic Cells Formed at the Infection Site Control the Induction of Protective T Helper 1 Responses against Leishmania

Abstract: Infection-induced inflammatory reactions involve a strong increase in dendritic cells (DCs) at the infection site and draining lymph nodes (dLNs). Whether inflammatory DCs are recruited to these locations or differentiate locally, and what their functional relevance is, remain unclear. Here we showed that during Leishmania infection, monocytes were recruited to the dermis and differentiated into "dermal monocyte-derived DCs," which subsequently migrated into the dLNs. In addition, monocyte recruitment to the d… Show more

“…In cutaneous infection or inflammation, dermal or epidermal APC such as DC, Langerhans cells, and macrophages are increased and activated, and these abundantly produce IL-12, IL-23, and IL-27 [11][12][13]. In particular, IL-12 and IL-23 production is highly enhanced in psoriatic skin lesions [11].…”

“…Les cellules dendritiques inflammatoires ont tout d'abord été identifiées chez la souris dans un modèle d'infection cutanée par la bactérie Leishmania major [4]. Cette population de cellules qui expriment des molécules typiques des cellules dendritiques (molécules du CMH II et intégrine CD11c) était absente avant l'infection, et apparaissait au site d'inflammation et dans les ganglions drainants après infection.…”

“…Après cette description initiale, de nombreuses études ont montré chez la souris l'existence d'une population cellulaire comparable dans de nombreux cas d'inflammation causée par des pathogènes, qu'il s'agisse de bactéries (Listeria monocytogenes, Streptococcus pneumoniae, Salmonella typhimurium, etc.) [4][5][6], virus (virus de l'herpès, virus de la grippe, etc.) [6][7][8], levures ou parasites [9,10].…”

“…Recruitment of monocytes (moDC precursors) into inflammatory sites is largely dependent on CCR2 (Serbina and Pamer, 2006). Functionally, moDCs are major producers of pro-inflammatory cytokines (Serbina et al, 2003;Xu et al, 2007;Zhan et al, 2010), inducers of Th1 differentiation (Leon et al, 2007) and memory T cell activation (Wakim et al, 2008), and antigen cross-presenting cells (Cheong et al, 2010). By exhibiting these potent functions, moDCs offer a protective immunity role as well as mediate immunopathology (Aldridge et al, 2009).…”
