Identification of Strain-Specific B-cell Epitopes in Trypanosoma cruzi Using Genome-Scale Epitope Prediction and High-Throughput Immunoscreening with Peptide Arrays
BACKGROUND The factors influencing variation in the clinical forms of Chagas disease have not been elucidated; however, it is likely that the genetics of both the host and the parasite are involved. Several studies have attempted to correlate the T. cruzi strains involved in infection with the clinical forms of the disease by using hemoculture and/or PCR-based genotyping of parasites from infec...
متن کاملGenome Sequence of Trypanosoma cruzi Strain Bug2148
Trypanosoma cruzi belongs to the group of mitochondrion-containing eukaryotes and has a highly plastic genome, unusual gene organization, and complex mechanisms for gene expression (polycistronic transcription). We report here the genome sequence of strain Bug2148, the first genomic sequence belonging to cluster TcV, which has been related to vertical transmission.
متن کاملEpitope Mapping: B-cell Epitopes
Immunoglobulin molecules are folded in a way that assembles sequences from the variable regions of both the heavy and light chains into a surface feature (comprised of up to six complementarity-determining regions (CDRs)) that is complementary in shape to a surface structure on the antigen. These two surface features, the ‘paratope’ on the antibody and the ‘epitope’ on the antigen, may have a c...
متن کاملIdentification and Mapping of Linear Antibody Epitopes in Human Serum Albumin Using High-Density Peptide Arrays
We have recently developed a high-density photolithographic, peptide array technology with a theoretical upper limit of 2 million different peptides per array of 2 cm(2). Here, we have used this to perform complete and exhaustive analyses of linear B cell epitopes of a medium sized protein target using human serum albumin (HSA) as an example. All possible overlapping 15-mers from HSA were synth...
متن کاملidentification of hitherto undefined b-cell epitopes by antibodies in the sera of vitiligo patients using phage-display peptide library
a random 12 mers phage library was used to screen a pool of immunoglo¬bulin fractions obtained from vitiligo patients. subsequent to panning experiments, a panel of affinity selected phage from vitiligo patients were obtained. this panel was tested using an elis a for their reactivity with pooled sera from patients and normal controls. among the 16 randomly selected clones, two of clones showed...
