Groups of amino acids showing similarities in inhibitory effects of alanine substitution could be identified by cluster analysis, and these may represent common epitopes on the molecule recognised by subgroups of patients.
As this protein gave the highest hit after purification by density gradient centrifugation and pooling PNA fractions, we postulated that this is the molecule recognised by PNA and secreted from the epidermis.
In conclusion, the carbohydrate epitopes of CA19-9, SLXn1, SLX, and TAG-72 could be present on the molecule recognised by the anti-CA130 or anti-CEA antibody; however, the epitopes of CA130 and CEA did not co-exist on the same molecule.
As antigenic peptides in the context of human leukocyte antigen (HLA) class I molecules are recognised by cytotoxic T lymphocytes (CTL), the downregulation of HLA class I molecules is one of the reasons why tumour cells can evade CTL-mediated anti-tumour immunity.
Both molecules are recognised by both highly variable γδ TCR and the invariant NKG2D receptor (discussed in the next section).
Exogenous antigens chaperoned by a HSP can be channelled into the endogenous pathway, presented by MHC class I molecules, and recognised by CD8+ T lymphocytes (Suto and Srivastava, 1995).
In addition, these surface molecules are recognised by the host immune response and may have a role in facilitating immunosurveillance for malignant cells (Hakomori, 2001).
The realization that peptides of greater than ten amino acids in length can be presented by MHCI molecules and recognised by cognate TCR has led to recent calls to broaden the algorithms widely used to predict MHCI-binding peptides 26.
The MICA molecules are recognised by lymphocytes T γδ, lymphocytes T αβ CD8+, and NK cells via their receptors NKG2D, present on their surfaces, in association with the DAP10 molecule, an adapter protein membrane [ 71, 72].
