Interleukin-10 messenger ribonucleic acid in human placenta: implications of a role for interleukin-10 in fetal allograft protection.
OBJECTIVE
Our purpose was to determine whether interleukin-10 is expressed in human placental tissue, which might imply a role for it in fetal allograft protection.


METHODS
Detection of interleukin-10 messenger ribonucleic acid in human placental tissue and in human placental JAR cells by reverse transcription-coupled polymerase chain reaction was studied.


RESULTS
Interleukin-10 messenger ribonucleic acid was detected in human placental tissue from term mothers and in human placental JAR cells. Sequence analysis of the expected interleukin-10 complementary deoxyribonucleic acid fragment revealed 100% homology to authentic interleukin-10 complementary deoxyribonucleic acid.


CONCLUSIONS
Our results indicated that human placental tissue from term mothers expressed high levels of interleukin-10 messenger ribonucleic acid, suggesting that cells that produce interleukin-10 and that are associated with the placenta may play a role in preventing rejection of the fetal allograft by the mother.
