Hematopoiesis Of Immature Myeloid Dendritic Cells In Stroma-Dependent Spleen Long-Term Cultures Occurs Independently Of Nf-Kb/Relb Function, Jonathan Tan, Keping Ni, Fei Le, Helen O'Neill

Objective The nuclear factor-κB (NF-KB)/RelB transcription factor plays an essential role in development of some dendritic cell (DC) subsets in mice. In this laboratory, immature myeloid DC are produced in vitro in a stroma-dependent murine spleen long-term culture (LTC) system. In LTC, DC differentiate from hematopoietic progenitors maintained within the stromal cell matrix. Expression and function of RelB in development of LTC-DC has been investigated, with a view to assessing the relationship between DC produced in this system and other known subsets of DC. Materials and Methods RelB expression by LTC-DC was confirmed by detection of protein by Western blotting, …
Concise Review: Dendritic Cell Development In The Context Of The Spleen Microenvironment, Jonathan Tan, Helen O'Neill
Concise Review: Dendritic Cell Development In The Context Of The Spleen Microenvironment, Jonathan Tan, Helen O'Neill

The dendritic cell (DC) population in spleen comprises a mixture of cells including endogenous DC progenitors, DC precursors migrating in from blood and bone marrow, and DC in different states of differentiation and activation. A role for different microenvironments in supporting the dynamic development of murine DC of different types or lineages is considered here. Recent evidence for production of DC dependent on splenic stromal cells is reviewed in the light of evidence that cell production is dependent on cells comprising an endothelial niche in spleen. The possibility that self-renewing progenitors in spleen give rise to DC with tolerogenic or …

Narcissus mosaic virus is a Potexvirus, a member of the Flexiviridae family of filamentous plant viruses. Fiber diffraction patterns from oriented sols of narcissus mosaic virus have been used to determine the symmetry and structural parameters of the viral helix. The virions have a radius of 55 ± 5 Å. The viral helix has a pitch of 34.45 ± 0.5 Å, with 7.8 subunits per turn of the helix. We conclude that all members of the Potexvirus genus have close to 8 subunits per helical turn.
