     Similarity profiles between helper T cell epitopes (of self または microbial antigens かつ allergens) and human or microbial SWISSPROT collections were produced.

[...] Epitopes (on self かつ nonself antigens) can cross-stimulate T cells at increasing potency as their similarity with nonself augments.

     Similarity profiles between helper T cell epitopes (of self または microbial antigens かつ allergens) and human or microbial SWISSPROT collections were produced. For each antigen, both collections yielded largely overlapping profiles, demonstrating that self-nonself discrimination does not rely on qualitative features that distinguish human from microbial peptides. However, epitopes whose probability of mimicry with self or nonself prevails are, respectively, tolerated or immunodominant and coexist within the same (auto-)antigen regardless of its self/nonself nature. Epitopes (on self かつ nonself antigens) can cross-stimulate T cells at increasing potency as their similarity with nonself augments.

接尾辞

-self

1. Used in forming intensive and reflexive forms of the singular personal pronouns.

使用する際の注意点

• The plural counterpart is -selves.
• In the third person, -self or -selves is attached to the pronoun's objective form (him, them); in the first person and second person, to its prenominal possessive form (my, your).
• The suffixes -self and -selves may be separated by an intervening word or phrase (especially own) from the rest of the pronoun. When this occurs, self or selves stands alone as its own word, and the pronoun's prenominal possessive form is necessarily used; hence "himself" becomes "his own self", not *"him own self".
• The use of "themself" instead of "themselves" is sometimes proscribed, but it follows the contrast with "yourselves" and "yourself" and "ourselves" and "ourself".
• These forms are sometimes used in formal contexts in place of the objective personal pronoun: "the quality of service you have received from ourselves" (us). This usage is often criticized.
