Studi Bio-Molekuler Virus Penyakit Jembrana: Sebagai Dasar Pengembangan Tissue Culture Vaksin
Abstrak
Patogenesis dan bio-molekuler virus penyakit Jembrana (JDV) hanya menyerang B-cells sebagai target selnya, sehingga antibodi (kekebalan humoral) tidak terbentuk sampai 2-3 bulan pasca infeksi. Peningkatan populasi CD8+ T-cells secara signifikan dan menurunnya CD4+ T-cells secara drastis selama phase akut berakibat turunnya rasio CD8:CD4 yang menyebabkan meningkatnya kepekaan hewan terhadap infeksi sekunder. Sembilan ekor sapi bali yang digunakan dalam penelitian ini dikelompokkan berdasarkan status infeksi terkait pengambilan sampel. Tujuh ekor diinfeksi dengan JDV isolate Tabanan/87 dan 2 ekor lainnya diinfeksi dengan BIV isolate R29, sebagai kontrol negatif (Non-JDV infected cattle). Sampel diuji terhadap identitas selular dan target sel, kekebalan selular dan ekpresi sitokin. Sampel diuji dengan uji Flow cytometry dan dianalisis dengan uji varian. Hasil penelitian menunjukkan bahwa perubahan sub-populasi sel-sel T terkait penyembuhan infeksi JDV memperkuat peranan kekebalan seluler dalam proses kesembuhan penyakit Jembrana. Bukti-bukti atas meningkatnya ekpresi gen-gen sitokin yang diproduksi oleh sel-sel T CD8 terutama, IFN-g dan IL-2, mengindikasikan pentingnya gen-gen ini dalam proses infeksi dan kesembuhan.
