Abstract
Conclusions: Our findings demonstrate a blood-prostate barrier in the rat ventral prostate with characteristics similar to the blood-testis barrier. This blood-prostate barrier is not affected by LPS-induced acute inflammation. Further, this persistent barrier apparently restricts the passage of leukocytes into prostate DF even in the presence of pronounced interstitial inflammation. This observation may help to explain the observation that expressed prostatic secretions in human males are often free of leukocytes in clinical prostatitis.
