RESUMEN
AIM To study the effects of ternatolide(tern) on expression of granulysin mRNA in the activated peripheral blood lymphocytes(PBLS) of the adults and children with pulmonary Mycobacterium tuberculosis(PMTB). METHODS Using competitive quantitative reverse transcription polymerase chain reaction(QC TR PCR)analyze granulysin gene expression in the PBLs. RESULTS The dosage of 100 mg?L -1 , 200mg?L -1 of ternatolide significantly enhanced the granulysin mRNA experession in PBLs in vitro stimulated phytohemagglutinin (PHA) from adults and children with PMTB (P0 05). CONCLUSION The molecular mechanism of tern. against intracellular pathogens might be associated with the inducting highly level on the expression of granulysin mRNA, a anti bacterial peptide in activated human cytotoxic lymphocytes.
