15 صفحه اولMultiple intracellular routes in the cross-presentation of a soluble protein by murine dendritic cells.
Soluble heat shock fusion proteins (Hsfp) stimulate mice to produce CD8+ CTL, indicating that these proteins are cross-presented by dendritic cells (DC) to naive CD8 T cells. We report that cross-presentation of these proteins depends upon their binding to DC receptors, likely belonging to the scavenger receptor superfamily. Hsfp entered DC by receptor-mediated endocytosis that was either inhib...
متن کاملCD11c+ dendritic cells are required for survival in murine polymicrobial sepsis.
CD11c+ dendritic cells (DCs) are APCs that link innate and adaptive immunity. Although DCs are lost from spleen and lymph nodes in sepsis, their role in outcome remains unclear. Transgenic mice (B6.FVB-Tg(.Itgax-DTR/EGFP.57)Lan/J) expressing the diphtheria toxin (DT) receptor on the CD11c promoter (DCKO mice) received 4 ng/kg DT, which resulted in depletion of 88-95% of mature myeloid and lymph...
متن کاملThe GTPase Rab3b/3c-positive recycling vesicles are involved in cross-presentation in dendritic cells.
Antigen cross-presentation in dendritic cells is a complex intracellular membrane transport process, but the underlying molecular mechanisms remain to be thoroughly investigated. In this study, we examined the effect of siRNA-mediated knockdown of 57 Rab GTPases, the key regulators of membrane trafficking, on antigen cross-presentation. Twelve Rab GTPases were identified to be associated with a...
متن کاملBone marrow dendritic cells deficient for CD40 and IL-23p19 are tolerogenic in vitro
Objective(s): In addition to pro-inflammatory role, dendritic cells (DCs) can also be anti-inflammatory when they acquire tolerogenic phenotype. In this study we tested the role of CD40 and IL-23p19 in antigen presenting function of bone marrow-derived DCs (BMDCs) by comparing BMDCs derived from CD40 knockout (CD40KO-DCs) and IL-23p19 (IL-23p19KO-DCs) knockout mice wit...
