Description
脊髄は神経線維で構成されている。脊髄を含む中枢神経系への損傷は機能消失をもたらす。最も多く見られる脊髄損傷(SCI)は挫傷(脊髄の打撲)および圧迫損傷(脊髄への長期間にわたる圧迫に起因する)である。成体哺乳動物の脊髄損傷では、軸索が再生不能になることにより、感覚消失、運動機能消失、および/または自律神経機能消失のみならず、永久麻痺をもたらすことがある。神経細胞が再生できない理由の一つは、神経細胞が脊髄損傷後に生じるグリア性瘢痕を越えられないことである。損傷によって誘発された病変部には、コンドロイチン硫酸プロテオグリカン(CSPGs)などの細胞外基質分子を含むグリア性瘢痕が生じる。CSPGSは、インビトロでは神経組織の成長を阻害し、インビボではCSPGsが豊富な部位での神経組織の再生を阻害する。CSPGsは例えば炎症など他の様々な状態に関与する。

【発明の概要】
【課題を解決するための手段】
好ましい実施形態において、そのようなコンドロイチナーゼABCI変異酵素は活性亢進を示す。他の好ましい実施形態において、そのようなコンドロイチナーゼABCI変異酵素は、UVまたは熱への曝露による不活性化を含む不活性化への抵抗性亢進を示す。できれば本発明のコンドロイチナーゼABCI変異酵素は055D2−3(配列ID番号:1)、079B6−2(配列ID番号:2)、079D2−2(配列ID番号:3)、057G1−1(配列ID番号:4)、023G6−4(配列ID番号:5)、005B12−3(配列ID番号:6)、および021B8−3(配列ID番号:_)から選択されるのが好ましい。
プロテウス・ブルガリスの野生型コンドロイチナーゼABCIのヌクレオチド配列は配列ID番号:7、コンドロイチナーゼABCIのアミノ酸配列は配列ID番号:8で示される。
前記製剤に加え、本発明の化合物はデポ製剤として製剤することも可能である。そのような長時間作用型製剤は埋め込み(皮下、筋肉内など)または筋肉内注射により投与可能である。
以下の方法は本発明の様々な実施形態の例証に用いられる。これらの方法は例証用であり、本発明の限定を意図するものではない。
熱的に安定な変異体は分子進化プロセスを通して生成されることが確認された。修飾DMB分析により、42℃、2時間で野生型cABCIに比べ熱的に安定なクローンが確認された。この温度での安定性は37℃ではさらに大きな安定性をもたらす可能性が高く、内在ミニポンプの投与への利用が可能になることにより、インビボ研究のための処理および送達が容易となる。個々のモジュールは全体として、試験パラメータで定義された予想範囲内の陽性ヒットをもたらした。
