      Abstract
      Peptida amiloid beta 42 (Aβ42) dikenal sebagai biomarker dini penyakit Alzheimer. Antibodi Aβ42 menjadi bahan antibodi spesifik atau antibodi monoklonal yang dapat dijadikan kit diagnostik penyakit Alzheimer berbasis ELISA. Antibodi diproduksi di hewan mencit melalui teknik imunisasi amiloid sehingga didapatkan antibodi monoklonal dari organ limpa pada mencit. Studi ini dilakukan untuk mempelajari amyloidopathy pada organ hati mencit pascaimunisasi antibodi amiloid beta 42 (Aβ42) sebagai marka penyakit Alzheimer. Studi ini menggunakan 20 ekor mencit lalu dibagi menjadi dua kelompok. Kelompok yang diimunisasi dengan Aβ42 dan kelompok kontrol. Mencit perlakuan diberikan vaksin dengan titer 15.000pg/mL dan diinjeksikan 100l/ekor melalui rute subkutan. Pengamatan histopatologi organ hati menggunakan pewarnaan Hematoksilin Eosin. Temuan lesio dianalisis menggunakan analisis deskriptif dan semikuantitatif tipe ordinal. Hasil pengamatan menunjukkan bahwa terdapat lesio infiltrasi sel radang dan nekrosis pada mencit perlakuan. Hasil pengamatan studi ini diharapkan dapat melengkapi informasi terkait efek dari imunisasi Aβ42 terhadap organ hati mencit sebagai hewan model.
       
      Amyloid peptide beta 42 (Aβ42) is known as an early biomarker of Alzheimer's disease. Antibody Aβ42 is a specific antibody or a monoclonal antibody that can be used as an ELISA-based Alzheimer's disease diagnostic kit. Antibodies are produced in mice through the amyloid immunization technique; monoclonal antibodies will be obtained from the spleen organ in mice. This study was conducted to study amyloidopathy in the liver of mice after immunization with amyloid beta 42 (Aβ42) antibody as a marker of Alzheimer's disease. This study used 20 mice and divided them into two groups. The group immunized with Aβ42 and the control group. This study uses 15.000pg/ml vaccine titter and injected to 10 mice via the subcutaneous route with 100l/mice dose. Histopathological observations of liver organs using Haematoxylin Eosin staining and the lesion was then analysed using ordinal type descriptive and semi-quantitative analysis. The results showed that there were inflammatory cell infiltration lesions and necrosis in immunized mice. The results of this study are expected to provide information regarding the effects of Aβ42 immunization on the liver of mice as animal models.
