although the number of plasma membrane receptor for chemotactic peptides in the nonstimulated neutrophils was not altered in psoriasis , the receptor up-regulation induced by preincubation of the cells with 1-10 nm of nonlabeled n-formyl-met-leu-phe at 37 degrees c was reduced when measured by subsequent fluoresceinated hexapeptide uptake at 0 degree c .
