Resumen
Dendritic cells (DC) constitute a heterogeneous leukocyte population having in common a unique capacity to induce primary T cell responses and are therefore most attractive candidates for immunomodulatory strategies. Two populations of blood DC (CD11c+ CD123dim and CD11c– CD123high) have been defined so far. However, their direct isolation for experimental purposes is hampered by their low frequency and by the lack of selective markers allowing large scale purification from blood. Here we describe the monoclonal antibody (mAb) M-DC8, which was generated by immunizing mice with highly enriched

Resumen
This is a comprehensive study of human kidney proximal tubular epithelial cells (PTEC) which are known to respond to and mediate the pathological process of a range of kidney diseases. It identifies various molecules expressed by PTEC and how these molecules participate in down-regulating the inflammatory process, thereby highlighting the clinical potential of these molecules to treat various kidney diseases. In the disease state, PTEC gain the ability to regulate the immune cell responses present within the interstitium. This down-regulation is a complex interaction of contact dependent/indep

Dendritic cells (DC) have the unique capacities to induce primary T cell responses. In mice, CD8α+DC are specialized to cross-prime CD8+ T-cells and produce IL-12 that promotes cytotoxicity. Human BDCA-3+DC share several relevant characteristics with CD8α+DC, but the capacities of human DC subsets to induce CD8+ T cell responses are incompletely understood. Here we compared CD1c+mDC1, BDCA-3+mDC2 and plasmacytoid DC (pDC) in peripheral blood and lymphoid tissues for phenotype, cytokine production and their capacities to prime cytotoxic T cells. mDC1 were surprisingly the only human DC that

Resumen
The human immunodeficiency virus (HIV)-1 is the causative agent of acquired immune deficiency syndrome (AIDS) worldwide. Till date there are no vaccines or cure for this infection as the virus has adapted myriad ways to remain persistent in the host where it causes severe damage to the immune system. Both humoral and cellular immune responses are mounted against HIV-1 during the initial phase of infection but fail to control viral replication as these responses are severely depleted during disease progression. Of great importance in HIV-1 research today is the in depth understanding of the typ

Many events associated with Human Immunodeficiency Virus (HIV) infection/replication occur in and around the germinal centers (GCs) of secondary lymphoid tissues where follicular dendritic cells (FDCs) reside, suggesting that this microenvironment may contribute unique signaling that is important to viral progression.

Resumen
Dendritic cells (DC) are key cells of the innate immune system required to prime adaptive immunity. Migration is central to their function to enable immune surveillance of the whole body and for prompt activation of the adaptive immune system. Immature DC assemble specialised actin structures called podosomes which are thought to be critical for efficient adhesion-mediated migration. Podosomes are, therefore, considered to be essential for DC function. Despite the great increase in literature regarding podosomes and related structures over recent years, still much is unknown about critical com

L'activation des lymphocytes T auxiliaires peut être régulée par des checkpoints immunitaires co-stimulateurs, tel que OX40 Ligand, ou co-inhibiteurs. Ces molécules ont été étudiées individuellement, dans des conditions spécifiques. Cependant, la contexte-dépendance pourrait expliquer une grande partie de la variabilité fonctionnelle des biomolécules. Il n'y a actuellement

Resumen
Background Previously, we identified a major myeloid-derived proinflammatory subpopulation of human blood dendritic cells which we termed slanDCs (e.g. Schäkel et al. (2006) Immunity 24, 767–777). The slan epitope is an O-linked sugar modification (6-sulfo LacNAc, slan) of P-selectin glycoprotein ligand-1 (PSGL-1). As slanDCs can induce neoantigen-specific CD4+ T cells and tumor-reactive CD8+ cytotoxic T cells, they appear as promising targets for an in vivo delivery of antigens for vaccination. However, tools for delivery of antigens to slanDCs were not available until now. Moreover, it is un

Resumen
Le cellule dendritiche (DCs) rappresentano una popolazione di cellule eterogenea con diversa origine, fenotipo e funzione che svolge un ruolo chiave nell' induzione, coordinazione e mantenimento delle risposte immunitarie adattative. La maggior parte delle conoscenze riguardanti le DCs sono state acquisite grazie ad esperimenti eseguiti con DCs fatte differenziare in vitro da monociti trattati con diverse combinazioni di citochine; in particolare è ormai noto che i monociti umani differenziano a DCs se coltivati con il fattore di stimolazione di colonie granulocita rie/macrofagiche(GM-CSF) e

Resumen
La communication intercellulaire est à la base de l'organisation d'ordre supérieur observée dans les tissus, les organes et l'organisme. Comprendre la communication intercellulaire et ses mécanismes sous-jacents qui sont impliqués dans le cancer est essentiel. Le microenvironnement des tumeurs du sein est composé d'une grande diversité cellulaire, telle que les cellules endothéliales, stromales ou immunitaires, qui peuvent influencer la progression tumorale ainsi que la réponse au traitement. Parmi les différentes populations de cellules immunitaires, les sous-populations de cellules dendritiq

Resumen
Surfactant proteins, SP-A and SP-D, are collagen-containing calcium-dependent (C-type) lectins, called, collectins. Their primary structure has four regions: a cysteine-linked N- terminal region involved in multimerization, a collagen region composed of Gly-X-Y repeats, coiled-coil neck region, and the C-terminal carbohydrate recognition domains (CRD) or C-type lectin domain. SP-A looks like a bouquet, while SP-D is a cruciform- like structure, with four arms of equal length. SP-A and SP-D have been shown to act as innate immune molecules at pulmonary as well as extra-pulmonary sites by bindin
