Balanced cytokine-producing pattern in mice immunized with an avirulent Trypanosoma cruzi
Soares Milena B. P.,Gon?alves Renata,Pyrrho Alexandre S.,Costa Deise A.
Anais da Academia Brasileira de Ciências , 2003,
Abstract: We have previously demonstrated that inoculation of BALB/c mice with trypomastigotes of CL-14, an avirulent Trypanosoma cruzi clone, prevents the development of parasitemia and mortality after challenge with virulent CL strain. In this report, we investigated the cytokine and antibody profiles induced by inoculation with CL-14 clone. Groups of mice were inoculated with trypomastigotes of CL-14 clone and challenged with infective CL strain. Challenged CL-14-inoculated mice had lower levels of IFN-g and higher production of IgG1 antibodies as compared to CL strain-infected mice. Previous inoculation with CL-14 clone partially prevented the suppression of IL-2 production caused by CL strain infection. No significant differences were found regarding IL-4 production by splenocytes from CL-14-inoculated or control groups after challenge with CL-strain. Our results show that protection against acute T. cruzi infection induced by CL-14 inoculation correlates with a balanced T1/T2 cytokine production, a profile likely to be beneficial for the host.

Abstract: strongyloides ratti larval extract was used for the standardization of elisa to detect genus-specific ige in human strongyloidiasis. forty serum samples from monoinfected patients shedding s. stercoralis larvae (group i), 40 from patients with other intestinal parasites (group ii), and 40 from copronegative healthy subjects (group iii) were analyzed. genus-specific ige levels (elisa index: ei) were significantly higher in the group i (ei = 1.43) than groups ii (ei = 0.70) and iii (ei = 0.71), showing positivity rates of 55%, 2.5% and 0%, respectively. similarly, sera from copropositive patients had significantly higher levels of total ige (866 iu/ml) as compared to those from group ii (302 iu/ml) and iii (143 iu/ml). a significant positive correlation was found between levels of strongyloides specific-ige and total ige in sera from patients with strongyloidiasis. in conclusion, s. ratti heterologous extract showed to be a useful tool for detecting genus-specific ige by elisa, contributing for a better characterization of the immune response profile in human strongyloidiasis.

Abstract: early interactions seem to be adaptive, it is fundamental to know them in order to understand human ontogenesis. this study compares data of observations of mother-baby dyads, analyzing the behavior of the partners, the complexity of the interchanges and their affective components. the participants were 56 dyads (28 with one-month old babies and 28 with five-month old babies), filmed in their homes in free situations. interaction episodes were identified and analyzed. the results showed the effect of the factor type of dyad (one or five months-old babies) in four dependent variables that indicate complexity of the interactions. differences in the manifestation of reciprocal affectivity of the partners were observed in the two groups. the interactions were predominantly face-to-face when the babies are one-month old, and the system of object stimulation is predominant when the babies are five-months old. this indicates a tendency observed in western urban groups. the affective manifestations and the presence of interactions which are characterized by the system of body contact favor the formulation of a hypothesis of the presence of an autonomous relational pattern. the results confirm the literature about the possibility of interchanges in initial stages of the development, and the study contributes for the knowledge of its characteristics. the affective aspect is stressed, and its constitutive role in interactions is emphasized, assuming its importance in child development.
