英文摘要
The goals of the proposed studies are to analyze the role of HLA class II
diversity in the development of immune responses in man. The epitopes of
the tetanus toxin (ttox) antigen which are immunodominant in the context of
different class II molecules will be determined. The following questions
will be addressed using L cell and B cell transfectants expressing high
levels of individual HLA class II molecules:
1)Do the immunodominant epitopes differ in individuals of different DR
and DQ type?
2)What is the relative contribution of DQ restricted responses to the
total response?
3)In heterogygous individuals, what is the contribution of "hybrid" DQ
molecules to the total DQ response? Are different epitopes
immunodominant?
4)What is the role of the DQomicron( chain in DQ-restricted responses?
5)Is there any evidence of ttox responses restricted to mixed isotypes
and which epitopes are used by such molecules?
6)Are there differences in the DR-restricted response in the context of
different DR4 subtypes and will antigen-specific and DR4-restricted T
cell be able to distinguish the various DR4 subtypes and to what extent?
7)What is the role of the third hypervariable (HV) region of DR molecules
in determining which epitopes are immunodominant in DR restricted
responses?
T cell responses will be analyzed by measuring both a) bulk proliferative
responses and b) the frequency of precursor T cells directed against
peptide fragments of the ttox antigen presented by different class II
transfectants. In addition, class II-restricted ttox-specific T cell
clones will be generated in order to study the effects of structural
variation in class II molecules on T cell recognition.
