Diversity of T Cell Epitopes in Plasmodium falciparum Circumsporozoite Protein Likely Due to Protein-Protein Interactions
Circumsporozoite protein (CS) is a leading vaccine antigen for falciparum malaria, but is highly polymorphic in natural parasite populations. The factors driving this diversity are unclear, but non-random assortment of the T cell epitopes TH2 and TH3 has been observed in a Kenyan parasite population. The recent publication of the crystal structure of the variable C terminal region of the protei...
متن کاملHLA-A*01-restricted cytotoxic T-lymphocyte epitope from the Plasmodium falciparum circumsporozoite protein.
Here, we report the identification of a novel CD8+ cytotoxic T-lymphocyte epitope on the Plasmodium falciparum circumsporozoite protein (3D7; amino acids 310 to 319 [EPSDKHIKEY]) that is restricted by HLA-A*01 and is recognized by human volunteers immunized with irradiated P. falciparum sporozoites. HLA-A*01 is the second most common HLA allele among Caucasians.
متن کاملgenetic diversity in the circumsporozoite protein gene of plasmodium falciparum from major endemic regions of iran
circumsporozoite protein (csp) is one of the stage specific antigens, which is used for the development of vaccines and to investigate the genetic diversity in plasmodium falciparum malaria parasite. polymerase chain reaction was used for typing of csp genes on 67 positive falciparum malaria patients from sistan and baluchistan province of iran. three fragments were detected for csp gene. twent...
متن کاملMonoclonal Antibodies against Plasmodium falciparum Circumsporozoite Protein
Malaria is a mosquito-borne infectious disease caused by the parasite Plasmodium spp. Malaria continues to have a devastating impact on human health. Sporozoites are the infective forms of the parasite inside mosquito salivary glands. Circumsporozoite protein (CSP) is a major and immunodominant protective antigen on the surface of Plasmodium sporozoites. Here, we report a generation of specific...
متن کاملInduction of cytotoxic T lymphocytes against the Plasmodium falciparum circumsporozoite protein by immunization with soluble recombinant protein without adjuvant.
Immunization of mice with irradiated malaria sporozoites induces protection that is dependent on CD8+ T cells, and adoptive transfer of CD8+ cytotoxic T lymphocyte (CTL) clones against rodent malaria circumsporozoite (CS) protein and sporozoite surface protein 2 completely protects against sporozoite challenge. Thus, there are now efforts to develop vaccines that induce CTL against the CS prote...
