Peningkatan Ekspresi IFN-y pada Paru Mencit yang Diinduksi Protein Adhesin 38- kDa Mycobacterium tuberculosis dan ISCOM per Oral Increasing Expression of IFN-y Lung Mice Induced withMycobacteriumTuberculosisAdhesin38 Kda Protein and Oral ISCOM)
ABSTRACT
Previous studies showed that tuberculosis vaccine induced a cellular immune response of 38-kDa M tuberculosis hemaggiutinin protein which was found in mice enterocytes. It can induce S-IgA secretion into the intestinal lumen and bronchiolus. It is known that the ISCOM is on effective adjuvantenhances the immune response. interferon(IFItexpression mainly occurs as a response to the microbes, like-viruses and bacteria, and their products.
This study aimed to investigate the impact of38-kDa adhesin protein administration with or without oral adjuvant ISCOM to the (IFN) expression in lung tissue of BALB/c mice. An experimental design was performed in 4 groups: control group, intervention group with 38-kDa protein adhesion administration, ISCOM adjuvant administration and combination of38-kilo protein adhesin with ISCOM. Expression of IFN-y was measured by immunohistochemical staining. Kruskall Wallis analysis identify significant difference of !FN-yexpression among all treatment groups (p=0,00). The Mann Whitney test stated that identify significant increasing of IFN-y expression in group with combination of protein adhesin and oral adjuvant ISCOM (mean±SD=126±17; p=0,000) when compared with the other groups. interestingly exposure with ISCOM only has potentiai effect in inducing iFN-y expression significantly whencompared to controls (p=0,000). It can be concluded that the administration of protein adhesin 38 kDa M tuberculosis will stimulate IFN-y expression in the lung tissue of BALSA mice, and the addition ofLSCOM will increase the impact.
