Drosophila melanogaster.

A number of these pathways and signalling systems have already been observed throughout development and hence, studies with models such as the fruit fly, can offer additional insight into how these signalling mechanisms function in humans.. A fresh system for collaboration in cell communication Investigators from the Institute of Research in Biomedicine have identified a new signalling system among cells in the fruit fly, Drosophila melanogaster. The researchers discovered that two independent groups of cells generate the same signal by different pathways and these cells subsequently take action together to send out the signal to the target cell.AIDS Healthcare Foundation is definitely proud to continue its second HIV Examining Tour over the US after the successful completion of its latest and ambitious 14 town AHF Magic Johnson HIV Tests Caravan in mid-2009.
