AB Phagocytosis of Treponema pallidum by cytokine-activated macrophages
aids bacterial clearance and lesion resolution in early syphilis. To
investigate the cytokine profiles of cells infiltrating primary and
secondary syphilis lesions, reverse transcription and polymerase chain
reaction (RT-PCR) were used to detect cytokine mRNA in 13 lesion
biopsies. Both primary and secondary lesions contained mRNA encoding
interleukin (IL)-2, interferon-gamma (IFN-gamma), IL-12p40, and IL-10.
In contrast to a lesion from a patient with recurrent herpes simplex
virus type 2, no message for IL-4 could be detected in any of the
syphilis lesions, and 10 of 13 had no mRNA for IL-5 or IL-13. These
findings are consistent with a Th1-predominant local cellular response
activating macrophages and support the hypothesis that
IFN-gamma-activated macrophages are primary effectors in treponeme
clearance.
