Human immune responses to Schistosoma mansoni vaccine candidate antigens.
To determine the naturally occurring immunological responses to the Schistosoma mansoni antigens paramyosin, IrV-5, Sm-23 (MAP-3), and triose phosphate isomerase (MAP-4), a total of 119 subjects from an area of endemicity for schistosomiasis, including "resistant" subjects (n = 17) were evaluated. Specific immunoglobulin G1 (IgG1), IgG2, IgG3, IgG4, and IgA levels for each of the antigens and t...
متن کاملIdentification of immunodominant epitopes of Schistosoma mansoni vaccine candidate antigens using human T cells.
Paramyosin and Sm14 are two of the six antigens selected by the World Health Organization as candidates to compose a subunit vaccine against schistosomiasis. Both antigens are recognized by individuals naturally resistant to Schistosoma mansoni infection and induced protective immunity in the murine model. Three Sm14 epitopes and eleven paramyosin epitopes were selected by their ability to bind...
متن کاملNaïve donor responses to Schistosoma mansoni soluble egg antigens.
Schistosome infection induces profound Th-biasing and immune suppression. Although much has been examined in mice, few studies have examined responses of naïve humans to schistosome antigens. In this study, we examined the response of naïve human peripheral blood mononuclear cells (nPBMC) to stimulation with Schistosoma mansoni soluble egg antigen (SEA) using a priming in vitro (PIV) assay. We ...
متن کاملImmune responses in mice after immunization with antigens from different stages of the parasite Schistosoma mansoni.
Mice responses to immunization with Schistosoma mansoni antigens were investigated. Priming with cercarial antigen preparation (CAP) induced significant (P < 0.05) IgM, IgG, IgG2a, IgG2b, and IgA increases, while booster caused a significant IgG1 increase. A soluble worm antigen preparation (SWAP) caused significant IgG elevation. Priming with soluble egg antigen (SEA) caused significant IgM an...
متن کاملImmune Responses to Candidate Vaccine Antigens Delivered Through Naked Plasmid and Mycobacterial Vectors
Tuberculosis (TB) is a major global health problem and has been declared “a global emergency” by the World Health Organization. The failures of the currently available vaccine against TB, i.e. Mycobacterium bovis BCG, to impart consistent protection against TB, have led to the need for alternative vaccines. The low molecular weight major antigenic proteins, i.e. PE35, CFP10 and ESAT6, encoded b...
