Mechanisms and Consequences of Dendritic Cell Migration
545
TL;DR: The molecular traffic signals that govern the migration of DCs throughout their life cycle are reviewed and it is shown that within peripheral tissues, DCs collect antigenic material and then traffic to secondary lymphoid organs, where they communicate with lymphocytes to orchestrate adaptive immune responses.

Lymphangiogenesis: Molecular Mechanisms and Future Promise
Tuomas Tammela,Kari Alitalo +1 more
TL;DR: The growth of lymphatic vessels is actively involved in a number of pathological processes including tissue inflammation and tumor dissemination but is insufficient in patients suffering from lymphedema, a debilitating condition characterized by chronic tissue edema and impaired immunity.

The lymphatic vasculature in disease
TL;DR: This review highlights the most recent developments in lymphatic biology and how the lymphatic system contributes to the pathogenesis of various diseases involving immune and inflammatory responses and its role in disseminating tumor cells.

AS04, an aluminum salt- and TLR4 agonist-based adjuvant system, induces a transient localized innate immune response leading to enhanced adaptive immunity.

TL;DR: Results support a model in which the addition of MPL to aluminum salt enhances the vaccine response by rapidly triggering a local cytokine response leading to an optimal activation of APCs, and support the favorable safety profile of AS04 adjuvanted vaccines.

HEVs, lymphatics and homeostatic immune cell trafficking in lymph nodes
Jean-Philippe Girard,Christine Moussion,Christine Moussion,Christine Moussion,Reinhold Förster +4 more
TL;DR: The current understanding of the functions of high endothelial venules, stroma and lymphatics in the entry, positioning and exit of immune cells in lymph nodes during homeostasis are reviewed, and the unexpected role of dendritic cells is highlighted in the control of lymphocyte homing through HEVs.

Antigen-Presentation Properties of Plasmacytoid Dendritic Cells
TL;DR: The evidence for a potential role of pDC in antigen capture, processing, and presentation to T cells at sites of infection and in the lymph nodes is examined.

Plasmacytoid monocytes migrate to inflamed lymph nodes and produce large amounts of type I interferon.
Marina Cella,David Jarrossay,Fabio Facchetti,Olga Alebardi,Hideo Nakajima,Antonio Lanzavecchia,Marco Colonna +6 more
TL;DR: Results, with the distinct cell phenotype, indicate that plasmacytoid monocytes represent a specialized cell lineage that enters inflamed lymph nodes at high endothelial venules, where it produces type I interferon.

T-cell priming by dendritic cells in lymph nodes occurs in three distinct phases
TL;DR: T-cell priming by DCs occurs in three successive stages: transient serial encounters during the first activation phase are followed by a second phase of stable contacts culminating in cytokine production, which makes a transition into a third phase of high motility and rapid proliferation.
Monocyte emigration from bone marrow during bacterial infection requires signals mediated by chemokine receptor CCR2
Natalya V. Serbina,Eric G. Pamer +1 more
TL;DR: In blood, Ccr2−/− monocytes could traffic to sites of infection, demonstrating that CCR2 is not required for migration from the circulation into tissues, and determining the frequency of Ly6Chi monocytes in the circulation.

Selective Recruitment of Immature and Mature Dendritic Cells by Distinct Chemokines Expressed in Different Anatomic Sites
Marie-Caroline Dieu,Béatrice Vanbervliet,Alain Vicari,J M Bridon,Elisabeth Oldham,Smina Ait-Yahia,Francine Brière,Albert Zlotnik,Serge Lebecque,Christophe Caux +9 more
TL;DR: The observation that CCR6 mRNA expression decreases progressively as DCs mature, whereas CCR7 mRNA expression is sharply upregulated, provides a likely explanation for the changes in chemokine responsiveness, and suggests a role for MIP-3α/CCR6 in recruitment of immature DCs at site of injury and for Mip-3β/CCr7 in accumulation of antigen-loaded mature DCs in T cell–rich areas.

T-cell function and migration. Two sides of the same coin.
TL;DR: This review will concentrate on the migration of T cells, which are at the heart of most adaptive immune responses, since T cells respond to pathogens only on direct contact with pathogen-derived antigen.
