multicolor flow cytometry analyses of cellular immune response in rhesus macaques

Il modello di macaco rhesus è attualmente il miglior modello disponibile per l&#39;HIV-AIDS rispetto alla comprensione della patogenesi e per lo sviluppo di vaccini e terapie<sup&gt; 1,2,3</sup&gt;. Qui, descriviamo un metodo per l&#39;analisi dettagliate fenotipica e funzionale delle risposte immunitarie cellulari, in particolare la produzione di citochine intracellulari di CD4 + e CD8 + T, oltre che i sottoinsiemi memoria individuale. Abbiamo ottenuto precise misure quantitative e qualitative per la produzione di interferone gamma (INF-) e interleuchina (IL) -2 in entrambi i CD4 + e CD8 + T cellule del macaco rhesus PBMC stimolati con PMA più ionomicina (PMA + I). I profili delle citochine erano diverse nei diversi sottoinsiemi di celle di memoria. Inoltre, questo protocollo ci ha fornito la sensibilità per dimostrare anche le frazioni minori di specifico antigene CD4 + e CD8 + sottogruppi di cellule T nei campioni di PBMC da macachi rhesus immunizzati con un vaccino cocktail busta peptide HIV sviluppate nel nostro laboratorio. La tecnica di citometria a flusso multicolore è un potente strumento per identificare con precisione le diverse popolazioni di cellule T<sup&gt; 4,5</sup&gt; Con citochine capacità di produzione<sup&gt; 6</sup&gt; In seguito a stimolazione aspecifica o antigene-specifiche<sup&gt; 5,7</sup&gt;.
