ex vivo expansion of tumor-reactive t cells by means of bryostatin 1/ionomycin and the common gamma chain cytokines formulation

Il a été rapporté que les patients du cancer du sein ont pré-existante des réponses immunitaires contre leurs tumeurs 1,2. Cependant, ces réponses immunitaires ne parviennent pas à fournir une protection complète contre le développement ou la réapparition du cancer du sein. Pour surmonter ce problème en augmentant la fréquence des cellules T réactives tumeurs, immunothérapie adoptive a été employé. Une variété de protocoles ont été utilisés pour l&#39;expansion des cellules T spécifiques de la tumeur. Ces protocoles, cependant, sont limités à l&#39;utilisation d&#39;antigènes tumoraux ex vivo pour l&#39;activation des cellules T spécifiques de l&#39;antigène. Très récemment, la chaîne gamma commune des cytokines comme l&#39;IL-2, IL-7, l&#39;IL-15 et IL-21 ont été utilisés seuls ou en association pour l&#39;amélioration de l&#39;anti-tumorale des réponses immunitaires 3. Toutefois, il n&#39;est pas clair ce que la formulation serait le mieux pour l&#39;expansion des cellules T réactives tumeur. Nous présentons ici un protocole pour l&#39;activation sélective et l&#39;expansion de la tumeur des cellules T réactives à partir du modèle de souris transgénique FVBN202 de carcinome mammaire HER-2/neu positifs pour une utilisation en thérapie cellulaire adoptive T du cancer du sein. Le protocole inclut l&#39;activation des cellules T avec bryostatin-1/ionomycin (B / I) et l&#39;IL-2 en l&#39;absence d&#39;antigènes tumoraux pour les 16 heures. B / Je activation imite signaux intracellulaires qui aboutissent à l&#39;activation des cellules T en augmentant la protéine kinase C et de l&#39;activité intracellulaire de calcium, respectivement 4. Ce protocole active spécifiquement les cellules T spécifiques de la tumeur tout en tuant les cellules T non pertinentes. Les cellules B / I-T activées sont cultivées avec de l&#39;IL-7 et IL-15 pendant 24 heures puis pulsé avec de l&#39;IL-2. Après 24 heures, les cellules T sont lavés, split, et cultivé avec de l&#39;IL-7 + IL-15 pour les 4 jours supplémentaires. L&#39;efficacité de tumeur spécificité et anti-tumorale des cellules T ex vivo élargi est déterminé.
