The cellular immune response to Onchocerca volvulus antigen (OvAg) was studied in 551 persons exposed to O. volvulus transmission in a hyperendemic area of Ghana, West Africa. A whole-blood assay showed that, in response to a soluble O. volvulus extract, cell proliferation, as well as interleukin (IL)-5 and IL-13 concentrations in the supernatants, were high in cultures of blood from microfilaria (mf)-negative persons and significantly decreased with increasing mf counts of the donors. Only background concentrations of interferon (IFN)-gamma were found, and these did not correlate with mf counts. In response to a mitogen, cells from all persons strongly reacted with proliferation and secretion of all 3 cytokines studied. These findings show that the response of human peripheral blood cells to OvAg does not include significant IFN-gamma production; that mf negativity is associated with IL-5 and IL-13 production but not, as previously suggested, with IFN-gamma production; and that IL-5 and IL-13 production decreases with increasing mf density.

pubmed:articleTitle |
Onchocerca volvulus-exposed persons fail to produce interferon-gamma in response to O. volvulus antigen but mount proliferative responses with interleukin-5 and IL-13 production that decrease with increasing microfilarial density.
