Dictyostelium
How do the amoebae know where to go? Amoebae are chemotactic: they can sense gradients of certain chemicals and move along them. Dicty is known to chemotax to two chemicals: folic acid, which is released by bacteria and used in the hunt for food, and cAMP, which is released by amoebae during starvation and used to find each other during aggregation. Cells have evolved a relay mechanism in which...
متن کاملA new environmentally resistant cell type from Dictyostelium
This paper describes the serendipitous discovery and first characterization of a new resistant cell type from Dictyostelium, for which the name aspidocyte (from aspis: Greek for shield) is proposed. These cells are induced from amoebae by a range of toxins including heavy metals and antibiotics, and were first detected by their striking resistance to detergent lysis. Aspidocytes are separate, r...
متن کاملdictyBase: a new Dictyostelium discoideum genome database
Dictyostelium discoideum is a powerful and genetically tractable model system used for the study of numerous cellular molecular mechanisms including chemotaxis, phagocytosis and signal transduction. The past 2 years have seen a significant expansion in the scope and accessibility of online resources for Dictyostelium. Recent advances have focused on the development of a new comprehensive online...
متن کاملDictyostelium finds new roles to model.
Any established or aspiring model organism must justify itself using two criteria: does the model organism offer experimental advantages not offered by competing systems? And will any discoveries made using the model be of wider relevance? This review addresses these issues for the social amoeba Dictyostelium and highlights some of the organisms more recent applications. These cover a remarkabl...
متن کاملDictyostelium morphogenesis.
During starvation-induced Dictyostelium development, up to several hundred thousand amoeboid cells aggregate, differentiate and form a fruiting body. The chemotactic movement of the cells is guided by the rising phase of the outward propagating cAMP waves and results in directed periodic movement towards the aggregation centre. In the mound and slug stages of development, cAMP waves continue to...
