An apparently paradoxical role for IFN-&lt;FONT FACE="Symbol"&gt;g&lt;/font&gt; in human Chagas' disease was observed when studying the pattern of cytokine production by peripheral blood mononuclear cells (PBMC) obtained from two groups of chagasic patients after specific stimulation with Trypanosoma cruzi-derived antigens. The groups studied were 1) patients treated with benznidazole during the acute phase of Trypanosoma cruzi infection and 2) chronically infected untreated patients. In the treated group, higher levels of IFN-&lt;FONT FACE="Symbol"&gt;g&lt;/font&gt; were produced by PBMC from individuals cured after treatment when compared to non-cured patients. In contrast, in the chronically infected group (not treated) higher levels of IFN-&lt;FONT...

Cytokines as determinants of resistance and pathology in human Schistosoma mansoni infection
Provedor de dados: 56
Autores: Corrêa-Oliveira,R.; Malaquias,L.C.C.; Falcão,P.L.; Viana,I.R.C.; Bahia-Oliveira,L.M.G.; Silveira,A.M.S.; Fraga,L.A.O.; Prata,A.; Coffman,R.L.; Lambertucci,J.R.; Cunha-Melo,J.R.; Martins-Filho,O.A.; Wilson,R.A.; Gazzinelli,G.
The role of different cytokines in the peripheral blood mononuclear cell (PBMC) proliferative response and in in vitro granuloma formation was evaluated in a cross-sectional study with patients with the different clinical forms and phases of Schistosoma mansoni infection, as well as a group of individuals "naturally" resistant to infection named normal endemic (NE). The blockage of IL-4 and IL-5 using anti-IL-4 and anti-IL-5 antibodies significantly reduced the PBMC proliferative response to soluble egg (SEA) and adult worm (SWAP) antigens in acute (ACT), chronic intestinal (INT) and hepatosplenic (HS) patients. Similar results were obtained in the in vitro granuloma formation. Blockage of IL-10 had no significant effect on either assay using PBMC from ACT...
