Chemorepulsion

Chemorepulsion is the directional movement of a cell away from a substance. Of the two directional varieties of chemotaxis, chemoattraction has been studied to a much greater extent. Only recently have the key components of the chemorepulsive pathway been elucidated. The exact mechanism is still being investigated, and its constituents are currently being explored as likely candidates for immunotherapies.

• Chemorepulsion Directional cell movement away from a substance
• Chemokines Secreted cell-signaling proteins able to induce chemotaxis in nearby cells.
• Immunorepulsion The active movement of immune cells away from a substance
