| Abstract | Because of its immunodominancy, and because it is conserved in different geographical isolates of Plasmodium falciparum, the repetitive sequence of the circumsporozoite protein, (Asn-Ala-Asn-Pro)n [(NANP)n], has been envisaged for the development of an anti-falciparum malaria subunit vaccine. However, the murine immune response to (NANP)n peptides, either carrier-free or coupled to carrier proteins, was shown to be inducible only by using strong (e.g., Freund's) adjuvants. Furthermore, response to the carrier-free peptide, administered in adjuvant, is genetically restricted to I-Ab mice. In the present paper, we report that high titers of antibodies against the NANP repetitive epitope were obtained in responder C57BL/6 (H-2b) mice when they were primed with live BCG (bacillus Calmette-Guérin Mycobacterium tuberculosis var. bovis) and immunized once with the synthetic peptide (NANP)40 coupled to tuberculin purified protein derivative (PPD) without the use of any adjuvant. This approach also led to the production of high titers of anti-NANP antibodies in ASW (H-2s), B10.RIII (H-2r), BALB/c (H-2d), C3H/He (H-2k), and DBA/1 (H-2q) nonresponder mice after two injections of the conjugate. In both cases, BCG priming was obligatory for the induction of antibodies reacting with the synthetic peptide. The levels of anti-NANP antibodies in nonresponder BALB/c mice were demonstrated to be comparable to the levels induced after PPD-(NANP)40 immunization in Freund's complete or incomplete adjuvant. The antibodies induced were also capable of recognizing P. falciparum sporozoites in immunofluorescence assays and, furthermore, these antibodies inhibited the penetration of live sporozoites into human hepatocytes in vitro. This system functioned independently of the subjects' resistance or susceptibility to BCG infection. Given the widespread natural exposure to mycobacterial antigens and the extensive use of BCG and PPD in the human population, this approach might be envisaged for vaccination with malaria peptides. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
