Abstract

Cytotoxic T Lymphocyte Associated Protein 4 (CTLA-4) adalah reseptor limfosit T yang berikatan dengan B7-1 dan B7-2 dari sel dendritik. CTLA-4 berperan menghambat kerja limfosit T. CTLA-4 diekspresikan oleh limfosit T pada fase istirahat atau setelah teraktivasi. CTLA-4 ditemukan pada sel dendritik, monosit, limfosit B, limfosit T, granulosit, dan stem sel CD34+. CTLA-4 berperan penting dalam perkembangan tumor, kanker serta autoimun. Literatur review ini bertujuan untuk membahas regulasi CTLA-4 limfosit T terhadap penyakit kanker dan autoimun. Metode: pencarian sistematis pada tiga database yaitu NCBI, science direct, dan nature dengan kata kunci “CLTA-4 and T cell and cancer and autoimmune” tahun 2021. Hasil: didapatkan 6 pilihan intervensi untuk mengurangi ekspresi CTLA-4 dan 1 intervensi untuk meningkatkan ekspresi CTLA-4. Kesimpulan: berdasarkan analisis terhadap 7 artikel penelitian, penurunan ekspresi CTLA-4 dapat menghambat pertumbuhan kanker dan peningkatan ekspresi CTLA-4 dapat menghambat berkembangnya autoimun maka dapat.

Abstract

Salmonelosis is a disease caused by the Salmonella sp. that causes a decrease in CD4+ expression. Black grape can boost the immune system through CD4+/CD8+ proliferation. The purpose of this study was to evaluate the activity of black grape extract to CD4+ and CD8+ expression in mice infected with Salmonella typhimurium. Research method is extract of black grapes, Salmonella typhimurium 108 infection, bacterial evaluation, extract therapy, flowcytometery examination, and 95% Anova test. The results of Anova test showed that the expression of CD4+ and CD8+ is not different. Biologically, an increase in CD4+ and CD8+ expression at doses of 100 mg/KgBB. A decrease in CD4+ and CD8+ expression at doses of 200 mg/KgBB and 400 mg/KgBB. Conclusion, biologically, black grape extract can increase the expression of CD4+ and CD8+ at low doses, as well as may decrease the expression of CD4+ and CD8+ at moderate to high doses.
