p class="abstract">The aim of this study was to evaluate the kinetics of the cytokines interferon-gamma, interleukin-2, interleukin-10 and interleukin-4 produced by spleen mononuclear cells stimulated by Con A during an experimental infection in rats with Fasciola hepatica. The proliferative response to Con A of Spm cells from rats infected with F. hepatica was significantly decreased on day 7 post-infection (P<0.006) and simultaneously an increase of interferon-gamma, interleukin-10 and interleukin-4 production along with a decrease of interleukin-2 by spleen mononuclear cells were observed. Interleukin-4 and interleukin-10 were involved in ablating cellular proliferation in vitro, as the addition of neutralising antibodies to either cytokine reversed the proliferative block. The addition of exogenous recombinant interleukin-2 also restored the proliferative response by spleen mononuclear cells obtained 7 days after infection from infected rats. At the same time, we found an incre
