Volume 9 Issue 3, March 2008

Lampreys express a diverse repertoire of variable lymphocyte receptors (VLRs). Cooper and colleagues (p 319) identify VLRB-producing cells that resemble mammalian B cells in the lamprey. A lamprey is shown in the foreground, and lamprey gill tissues immunostained for VLRB (green) and BrdU (red) are shown in the background; nuclei are stained with DAPI (blue). Artwork by Lewis Long.

  • Basophils have long been suspected to be potent inducers of T helper type 2 differentiation. Sokol and colleagues now demonstrate that basophils are required for adoption of the T helper type 2 fate in vivo in response to allergens with protease activity.

  • Both activation and termination of transcription factor NF-κB signaling require ubiquitin modification of pathway components. The E3 ligase Itch teams up with the NF-κB inhibitor A20 to edit the composition of ubiquitin chains on the signaling adaptor RIP, thereby limiting inflammatory responses.

  • Naive T cells can spend hours 'sampling' dendritic cells before making a stable conjugate with a single dendritic cell. It is the antigen 'dose' that determines how long this process takes.

  • Two groups demonstrate proteolytic activity for MALT1, a component of the signaling pathway mediating antigen receptor–dependent stimulation of the transcription factor NF-κB, and identify its first substrates.

  • Kruppel-like factor 2 is now shown to regulate chemokine receptor expression in lymphocytes, which leads to their homing to nonlymphoid organs after they leave the thymus.
