TL;DR: It is reported that the chemokine receptors CXCR4 and CCR7 are highly expressed in human breast cancer cells, malignant breast tumours and metastases and their respective ligands CXCL12/SDF-1α and CCL21/6Ckine exhibit peak levels of expression in organs representing the first destinations of breast cancer metastasis.

Toll-like receptor control of the adaptive immune responses.
Akiko Iwasaki,Ruslan Medzhitov +1 more
TL;DR: Recognition of microbial infection and initiation of host defense responses is controlled by multiple mechanisms and recent studies have provided important clues about the mechanisms of TLR-mediated control of adaptive immunity orchestrated by dendritic cell populations in distinct anatomical locations.

TL;DR: A new mechanism for bacterial uptake in the mucosa tissues that is mediated by dendritic cells (DCs) is reported, which open the tight junctions between epithelial cells, send dendrites outside the epithelium and directly sample bacteria.

Chemokines and leukocyte traffic
TL;DR: Over the past ten years, numerous chemokines have been identified as attractants of different types of blood leukocytes to sites of infection and inflammation and are now known to also function as regulatory molecules in leukocyte maturation, traffic and homing of lymphocytes, and the development of lymphoid tissues.

TL;DR: The current status of gene targeting with particular emphasis on germ line modification of the mouse genome is discussed, and the different methods so far employed to identify those rare embryonic stem cells in which the desired targeting event has occurred are described.

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.
