【発明の詳細な説明】 HIV蛋白質のCTL−エピトープを含むペプチド類とその利用 この発明は、細胞毒性リンパ球(以下、r CT L Jと略記する)工と1・ −ブを含有するペプチドに関し、特に人体免疫不全ウィルス(以下、rHIVJ と略記する)タンパク質、およびCTLエピトープを含有するペプチド断片とそ の用途に関する。これらのペプチドあるいは誘導体は、CTL応答を誘導あるい は促進するために使用することができる。[Detailed description of the invention] Peptides containing CTL-epitope of HIV protein and their use This invention relates to cytotoxic lymphocyte (hereinafter abbreviated as rCTLJ) technology and 1. In particular, human immunodeficiency virus (hereinafter referred to as rHIVJ) (abbreviated as ), and peptide fragments containing CTL epitopes and their Concerning the use of. These peptides or derivatives induce or induce CTL responses. can be used to promote.
ウィルス感染の細胞媒介性免疫(以下、rCM’IJと略記するとする)は、ウ ィルス感染に対する宿主防衛と想定されている。このCM工は、HIVあるいは エイズウィルスに対する有効なワクチンの開発において重要視されている。それ は、HIVワクチンあるいは治療法が必ずしも合理的な予防方法ではなかったか らである。そこでその後は、前記HIVに対するCMI応答の誘導、ならびに前 記CTL応答を刺激するH i Vタンパク質の特殊なエピトープの特定のガロ へと、次第に関心が移行されて来た。Cell-mediated immunity to viral infection (hereinafter abbreviated as rCM'IJ) is It is assumed to be a host defense against virus infection. This commercial worker is HIV or It is considered important in the development of an effective vaccine against the AIDS virus. that Are HIV vaccines or treatments not necessarily a reasonable method of prevention? It is et al. Therefore, after that, the induction of the CMI response against the HIV, as well as the specific galvanotopes of specific epitopes of H i V proteins that stimulate CTL responses. Interest gradually shifted to this.
この発明は、まず第一に、HIVタンパク質によって誘発されるCTL、あるい はそのCTLエピトープによって認識されるところのエピトープを含有するペプ チド断片を提供する。This invention first focuses on CTL induced by HIV protein or is a peptide containing the epitope recognized by the CTL epitope. Providing chido fragments.
さらに好ましくは、前記ペプチド断片が、NEF、GAG、あるいはENVタン パク質によって誘発されるCTL、またはそれらのCTLエビ)・−プによって 認識されるペプチド断片である。More preferably, the peptide fragment is NEF, GAG, or ENV protein. protein-induced CTLs, or those CTL shrimp). It is a recognized peptide fragment.
この発明において「ペプチド断片」とは、CTLエピトープを含む従来のタンパ ク質の有するアミノ酸基よりも少数のアミノ酸基を有するペプチドを意味する。In this invention, "peptide fragment" refers to a conventional protein fragment containing a CTL epitope. This refers to a peptide that has fewer amino acid groups than that of a protein.
1個のエピトープを含むペプチド断片で、そのエピトープがI−(I Vタンパ ク質によって誘発されたCTLによって認識されるものも、この発明ではCTL エピトープを含むペプチド断片と称する。A peptide fragment containing one epitope, which epitope is I-(IV protein). What is recognized by CTLs induced by CTLs is also recognized by CTLs in this invention. It is called a peptide fragment containing an epitope.
これらのペプチド断片は、従来存在するタンパク質またはそれらのCT Lエピ トープによって誘発されたCTLがこれを認識するのであれば、従来のタンパク 質の断片、またはその類似体であってもよい。These peptide fragments are derived from conventional proteins or their CTL epitopes. If the CTL induced by the tope recognizes this, the conventional protein or an analog thereof.
これらのペプチド断片は、CTLエピトープを形成するアミノ酸基のみによって 構成されていても、また追加のアミノ酸基が含まれていてもよい、但し、断片の アミノ酸基の数は従来のものよりも少ない。These peptide fragments are separated by only the amino acid groups that form the CTL epitope. or may contain additional amino acid groups, provided that the fragment The number of amino acid groups is smaller than conventional ones.
