WebNov 3, 2011 · It has been reported that a critical cell-cell distance of less than (i.e., ) is necessary for cells to relay signals during chemotaxis and form aggregation streams. Increasing the distance between cells hinders their capacity to sense each other and relay cAMP signals . Cells appear to have at least similar if not higher sensitivity to QSF ... WebMar 30, 2024 · Here, we use predictive modeling and experiments with Dictyostelium cells to show that competition between different ligands that bind to the same receptor leads to effective chemorepulsion. 8-CPT-cAMP, widely described as a simple chemorepellent, is inactive on its own and only repels cells when it acts in combination with the attractant …
