Messenger RNA (mRNA) expression for the antimicrobial peptides beta-defensin-1 and beta-defensin-2 in the male rat reproductive tract: beta-defensin-1 mRNA in initial segment and caput epididymidis is regulated by androgens and not bacterial lipopolysaccharides.
Mechanisms of antimicrobial protection in male reproductive organs are poorly understood. Defensins are antimicrobial peptides produced by many epithelial tissues. The goals of the present study were 1). to test the hypothesis that adult rat male reproductive organs express mRNA for rat beta-defensin (RBD)-1 and RBD-2, 2). to examine if defensin mRNA… (More)
