The recent discovery of a receptor needed for lymphocyte migration into lymphoid follicles indicates that multiple chemoattractive gradients allow lymphocytes to navigate to specialized niches in lymphoid organs.

Migration of a fibroblast along a collagen fiber can be regarded as cell locomotion in one-dimension (1D). In this process, a cell protrudes forward, forms a new adhesion, produces traction forces, and releases its rear adhesion in order to advance itself along a path. However, how a cell coordinates its adhesion formation, traction forces, and rear release in 1D migration is unclear. Here, we ...

This paper aims to show that micro-kernels are a more suitable environment for the implementation of process migration than conventional mono-lithic kernels. This premise is illustrated with an implementation of migration on top of the Chorus micro-kernel. The implementation emphasises the modularisation of the various components of a migration implementation, as well as drawing a strong distin...

Macrophage migration inhibitory factor (MIF) was the original cytokine, described almost 50 years ago and has since been revealed to be an important player in pro-inflammatory diseases. Recent work using MIF mouse models has revealed new roles for MIF. In this review, we present an increasing body of evidence implicating the key pro-inflammatory cytokine MIF in specific biological activities re...

This is a review of the history of labor migration as it has affected the Arab world from the oil boom of the early 1970s to the present, with particular attention to the changing flow of remittances from migrants to their country of origin. (SUMMARY IN FRE AND SPA)

The planar cell polarity (PCP) pathway is best known for its role in polarizing epithelial cells within the plane of a tissue but it also plays a role in a range of cell migration events during development. The mechanism by which the PCP pathway polarizes stationary epithelial cells is well characterized, but how PCP signaling functions to regulate more dynamic cell behaviors during directed ce...
