Compensatory T-Cell Regulation in Unaffected Relatives of SLE Patients, and Opp...
Fesel, C.; Barreto, M.; Ferreira, R.C.; Costa, N.; Venda, L.L.; Pereira, C.; Carvalho, C.; Morães-Fontes, M.F.; Ferreira, C.M.; Vasconcelos, C.In human systemic lupus erythematosus (SLE), diverse autoantibodies accumulate over years before disease manifestation. Unaffected relatives of SLE patients frequently share a sustained production of autoantibodies with indiscriminable specificity, usually without ever acquiring the disease. We studied relations of IgG autoantibody profiles and peripheral blood activated regulatory T-cells (aTregs), represented...
IgG autoantibody to brain beta tubulin III associated with cytokine cluster-II ...
Bansal, D.; Herbert, F.; Lim, P.; Deshpande, P.; Becavin, C.; Guiyedi, V.; de Maria, I.; Rousselle, J.C.; Namane, A.; Jain, R.; Cazenave, P.A.We investigated the significance of these self-reactive antibodies in clinically well-defined groups of P. falciparum infected patients manifesting mild malaria (MM), severe non-cerebral malaria (SM), or cerebral malaria (CM) and in control subjects from Gondia, a malaria epidemic site in central India using quantitative immunoprinting and multivariate statistical analyses. A two-fold complete-linkage hierarchi...
Self-reactivities to the non-erythroid alpha spectrin correlate with cerebral m...
Guiyedi, V.; Chanseaud, Y.; Fesel, C.; Snounou, G.; Rousselle, J.C.; Lim, P.; Koko, J.; Namane, A.; Cazenave, P.A.; Kombila, M.; Pied, S.Hypergammaglobulinemia and polyclonal B-cell activation commonly occur in Plasmodium sp. infections. Some of the antibodies produced recognize self-components and are correlated with disease severity in P. falciparum malaria. However, it is not known whether some self-reactive antibodies produced during P. falciparum infection contribute to the events leading to cerebral malaria (CM). We show here a correlation...
Total and functional parasite specific IgE responses in Plasmodium falciparum-i...
Duarte, J.; Deshpande, P.; Guiyedi, V.; Mecheri, S.; Fesel, C.; Cazenave, P.A.; Mishra, G.C.; Kombila, M.; Pied, S.Blood samples were collected from controls and P. falciparum-infected patients before treatment on the day of hospitalization (day 0) in India and, in addition, on days 7 and 30 after treatment in Gabon. Total IgE levels were determined by ELISA and functional P. falciparum-specific IgE were estimated using a mast cell line RBL-2H3 transfected with a human Fcε RI α-chain that triggers degranulation upon human I...
Clusters of cytokines determine malaria severity in Plasmodium falciparum - Inf...
Prakash, D.; Fesel, C.; Jain, R.; Cazenave, P.A.; Mishra, G.C.; Pied, S.We investigated the role of interferon (IFN)- gamma , interleukin (IL)-1 beta , IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, tumor necrosis factor (TNF)- alpha , and transforming growth factor (TGF)- beta in clinically well-defined groups of Plasmodium falciparum-infected patients manifesting mild malaria (MM), severe noncerebral malaria (SM), or cerebral malaria (CM) and in control subjects from Gondia, a malaria-end...
Increased polyclonal immunoglobulin reactivity toward human and bacterial prote...
Fesel, C.; Goulart, L.F.; Neto, A.S.; Coelho, A.; Fontes, C.J.F.; Braga, E.M.; Vaz, N.M.The observed difference in polyclonal antibody production seems related to intrinsic activation states of infected individuals, rather than to parasite-antigen specific immune responses. However, it appears influenced by preceding stimuli. This supports the idea that acquired clinical immunity may not exclusively depend on antigen-specific responses, but also on the individual polyclonal reaction.
