项目摘要
DESCRIPTION: (adapted from applicant's abstract) Research to continue the
development of instrumentation and methods for the sequence analysis of peptide
antigens presented to the immune system in association with class I and class
II molecules of the major histocompatibility complex is proposed. Routine
detection and characterization of disease associated antigens present at the
attomole level in a mixture of 10,000 self peptides is the expected outcome.
Identification of disease associated antigens is an important first step in the
development of vaccines or other immune system modulators that are effective
against bacterial and viral infections, cancer, autoimmune disorders and tissue
transplant rejection. Multistage chromatography in conjunction with our
recently developed, automated peak parking technology plus nanoliter/min, high
performance liquid chromatography and high performance capillary
electrophoresis interfaced to an ion trap mass spectrometer via an electrospray
ionization source will be employed to achieve this goal. Specific aims of the
proposed research include the following: (1) to identify melanoma specific
antigens presented by the class I molecules, HLA A2.1, A1 and A3, and the class
II molecule, DR4, (2) to identify minor histocompatibility antigens associated
with graft-vs-host disease and tissue transplant rejection, (3) to identify
peptides derived from myelin basic protein as well as cross reactive self
peptides that are presented by the multiple sclerosis associated class II
molecule, DR15Dw2, and recognized by T-cell clones derived from multiple
sclerosis patients, (4) to identify peptides presented by the class I molecule,
B27, that are unique to individuals diagnosed with ankylosing spondylitis (5)
to identify peptides presented by the class I molecule, A2.1, that are unique
to individuals diagnosed as having chronic lymphocytic leukemia, (6) to
identify and characterize peptides presented by HLA-A2.1, that have been post
translationally modified by either phosphorylation or glycosylation, (7) to
identify class II peptides presented by the HLA-DR4Dw4 molecule in the presence
and absence of the chaperone molecule, HLA-DM.
