For example, cell membrane integrins on circulating leukocytes are maintained in an inactive state to avoid epithelial cell attachment; they are activated only in response to stimuli such as those received at the site of an inflammatory response.
Por exemplo, as integrinas da membrana celular dos leucocitos circulantes mantéñense en estado inactivo para evitaren a adhesión a células epiteliais; soamente se activan en resposta a estímulos como os que reciben nos sitios onde hai unha inflamación.
