Embodiment I

[0155] Isolation of class I antigens is carried out using the method described in the above-mentioned related application. The naturally processed peptides are then isolated and sequenced using the methods described herein. Determine an allele-specific motif and various algorithms, and perform a set of quantitative binding experiments.

[0156] The various motifs identified above for the amino acid sequence of HLA-A2.1 alleles from several antigens were used to analyze whether these motifs exist. Table 3 provides the results of these studies. The letter "J" stands for norleucine.

[0157] Some of the above embodiments are provided to illustrate the present invention, not to limit its scope. Other variants of the present invention are easily met by those of ordinary skill in the art, and they are included in the appended claims. All publications, patents and patent applications cited herein are incorporated herein by reference.

Abstract

The present invention provides means and methods for selecting immunogenic peptides and immunogenic peptides capable of specifically binding to glycoproteins encoded by HLA alleles and inducing T cell activation in T cells restricted by the alleles combination. These peptides can be used to elicit an immune response against the desired antigen.
