摘要:
There is provided, inter alia, a method for the prophylaxis of productive malaria infection in travelers to endemic regions comprising the administration of suitable amounts of a formulation comprising a Plasmodium antigen or an immunogenic fragment or derivative thereof and an adjuvant, comprising a lipid A derivative and a saponin in a liposome formulation.
摘要:
The present invention pertains to the protection against malaria. More particularly, the invention is based on the characterisation of a novel liver and sporozoite-stage P. falciparum antigen, referred to as LSA-5. This antigen is highly antigenic and the prevalence of antibodies in subjects living in endemic areas is extremely high (ca. 90 %). The invention concerns antigenic peptides or polypeptides, mixotopes and conjugates comprising part of the sequence of LSA-5, as well as immunogenic compositions, vaccines and kits comprising these.

PROBLEM TO BE SOLVED: To provide a recombinant hepadnavirus nucleocapsid protein, i.e., a hepatitis B core (HBc) chimeric protein that self-assembles into particles after expression in a host cell.SOLUTION: A chimeric, carboxy-terminal truncated hepatitis B virus nucleocapsid protein (HBc) is disclosed that is engineered for both enhanced stability of self-assembled particles and the display of an immunogenic epitope. The display of the immunogenic epitope is displayed in the immunogenic loop of HBc, whereas the enhanced stability of self-assembled particles is obtained by the presence of at least one heterologous cysteine residue near the carboxy-terminus of the chimeric molecule. Methods for making and using the chimera are also disclosed.

PROBLEM TO BE SOLVED: To provide: a method for detecting and measuring malaria infection using the induction by hemozoin (HZ); a method for screening a vaccine for malaria infection and a preventative or therapeutic agent for malaria infection using the method for detecting and measuring; and a method for regulating the induction of natural immunity using the HZ, synthetic HZ or derivatives thereof as an adjuvant or immunostimulant.SOLUTION: Malaria infection is detected and measured by detecting and measuring HZ-induced, TLR9-mediated and MyD88-dependent natural immune activity. The detection and measurement of malaria infection can be used to diagnose malaria infection. The method for detecting and measuring is also used for screening a vaccine for malaria infection and a preventative or therapeutic agent for malaria infection. Further, HZ, synthetic HZ or derivatives thereof are used as an adjuvant or immunostimulant to regulate HZ-induced natural immune induction.
