Article Abstract:

Bacteria take away iron from the organisms, to solve the problem of taking up iron into cells, organisms have developed numerous iron-solublization technologies. The lipocalins are a large family that have attracted structural biologists attention and whose functions are still unknown are also iron carriers and provide and innate defence against micro organisms.

Coupling and cross-presentation

Article Abstract:

Studies of cultured cells have shown that the immune system has a clever way of dealing with microorganisms that invade the cells. Various investigations have shown that cross-presentation can involve the transfer of larger protein fragments, emphasizing that gap-junction-mediated cross-presentation is not the only mechanism for antigen transfer.
