The bone marrow contains specialized niches that support hematopoiesis. Jung and colleagues (p 388) identify a new dendritic cell subset that provides survival factors for mature B cells residing in the bone marrow. The original image shows perivascular dendritic cells (green) and blood vessels (red) in mouse skull bone marrow. Image by Anita Sapoznikov & Vyacheslav Kalchenko. Artwork by Lewis Long.

    TLR4 somehow manages to activate both MyD88- and TRIF-dependent signaling. According to Medzhitov and colleagues, TLR4 engages MyD88 and TRIF sequentially at the cell surface and in endosomes, respectively, thereby providing access to distinct pools of signaling proteins.

    The bone marrow contains specialized microenvironments that maintain blood cells and supply the requisite factors for their development. Newly identified bone marrow–resident dendritic cells create unique niches for mature B cells.

    The homing of lymphocytes to secondary lymphoid organs occurs at specialized blood vessels, the high endothelial venules. Autotaxin, a phospholipid-producing enzyme secreted by high endothelial venule endothelium, is a new participant found to facilitate the entry of lymphocytes into secondary lymphoid organs.

    Activation of the transcription factor NF-κB by Toll-like receptors must be controlled to avoid excessive inflammation. The tripartite-motif protein family member TRIM30α has now been shown to mediate a negative regulatory feedback mechanism curtailing such responses.
