Abstract
During the past several years, a number of studies on a variety of cell types have demonstrated the importance of Ca^2+^ in the control of the mechanism that produces cell volume recovery following a hypoosmotic stress. We have been studying the details of this control using the red blood cell from the bivalve mollusc, Noetia ponderosa, as a model. Volume recovery by these molluscan cells is a Ca^2+^‐sensitive process that involves initial Ca^2+^ entry, followed by phosphorylation of certain membrane‐associated proteins and taurine efflux. This paper reviews the present state of those studies and presents a working hypothesis of the nature of the mechanism. © 1994 Wiley‐Liss, Inc.
