Abstract

Penyakit Demam Berdarah Dengue (DBD) disebabkan oleh infeksi virus dengue yang dibawa Aedes aegypti (Ae. aegypti) sebagai vektor primernya. Pengendalian vektor pada penyakit DBD masih belum maksimal. Selain itu vaksin yang belisensi untuk penyakit DBD masih belum dilaporkan. Melalui pengembangan TBV salah satunya dengan memanfaatkan komponen saliva vektor. aliva vektor memiliki potensi dalam meningkatkan transmisi patogen ke tubuh inang, maka perlu adanya karakterisasi molekul dalam saliva nyamuk termasuk faktor imunomodulator. Karakterisasi faktor imunomodulator saliva Ae. aegypti dilakukan melalui uji reaksi silang antara protein kelenjar saliva Ae. aegypti dengan beberapa plasma darah manusia. Hasil penelitian menunjukkan adanya protein spesifik yang dikenali antibodi dalam plasma darah orang endemik dengan berat molekul ~ 37 kDa. Hal ini megindikasikan bahwa di dalam tubuh penduduk endemik telah mengembangkan antibodi anti-saliva Ae. aegypti yang diduga berperan penting dalam resistensi terhadap infeksi virus dengue.

Abstract

Purification of 31 and 56 kDa Immunogenic Proteins from the Salivary Glands of Aedes aegyptiThe salivary gland of arthropod vector contains various bioactive compounds and plays a role in the transmission of pathogens to the host. The host develops anti-salivary antibodies against vector saliva exposure. Our previous research has identified two immunogenic proteins with molecular weights of 31 and 56 kDa from the Aedes aegypti salivary gland protein extract. However, the role of the 31 and 56 kDa immunogenic proteins from saliva Ae. aegypti is not fully known, so it is necessary to purify two immunogenic protein fractions to better specify the target of developing a dengue vaccine. This study aimed to purify the 31 and 56 kDa immunogenic protein fractions by electroelution and dialysis methods. The purification of the two protein fractions has been successful which were confirmed by the SDS-PAGE by the existence of single-band parallel to the positive control. These results were further supported by the dot blot analysis which showed a positive reaction in the form of dark spots in the two protein fractions which were reacted with dengue patients' serum, endemic healthy people, and neonates. These results indicated that the purified 31 and 56 kDa immunogenic protein fraction can be identified by specific antibodies.Keywords: dialysis, electroelution, immunogenic, purification, saliva  ABSTRAKKelenjar saliva vektor arthropoda mengandung berbagai senyawa bioaktif dan berperan dalam transmisi patogen ke tubuh inang.

Abstract

BackgroundDengue virus is transmitted by several species of Aedes mosquitoes, with Aedes albopictus as secondary vector. During blood feeding, these vectors inject saliva into the vertebrate hosts. The saliva contains anticoagulant, anti-inflammatory and immunogenic factors. The objective of this research was to detect immunogenic proteins from Ae.albopictus salivary glands reacting with sera of people living in dengue endemic areas. MethodsThe identification of immunogenic proteins of Ae. albopictus salivary gland used one-dimensional gel electrophoresis (sodium dodecyl sulfate polyacrylamide gel electrophoresis), and western blot analysis, respectively. To determine the immunogenic nature of the candidate proteins, the antigens from the salivary gland of Ae. albopictus were reacted with sera from healthy persons, dengue hemorrhagic fever (DHF) patients, and neonates, each of the groups comprising 10 samples. ResultsThe protein profiles of Ae. albopictus salivary glands showed 13 bands with molecular weights from 16 kDa up to 97 kDa, i.e. 16, 17, 26, 28, 31, 32, 45, 55, 60, 67, 73, 76, and 97 kDa. According to western blot analysis result, the 31 kDa proteins were recognized in all endemic population sera, both in DHF patients and healthy persons. In contrast, protein bands of 47 and 67 kDa were only recognized by the sera of DHF patients. ConclusionThree immunogenic proteins of 31, 47 and 67 kDa were detected from Ae. albopictus salivary glands. These immunogenic proteins may be developed as candidate biomarkers for bite exposure to Ae. albopictus and as vector-based DHF vaccines.

Abstract

Penggunaan pengharum ruangan sintetik ternyata memiliki dampak negatif bagi kesehatan karena beberapa senyawa Volatile Organic Compounds yang dilepaskan tergolong ke dalam senyawa beracun dan bersifat karsinogen. Penggunaan pengharum ruangan alami merupakan pilihan yang baik guna menghindari risiko tersebut. Kopi merupakan komoditas perkebunan di Indonesia yang memiliki nilai ekonomis tinggi. Komponen penyusun kopi yang mulai banyak dikembangkan adalah minyak kopi. Kopi memiliki banyak kandungan kimia seperti kafein, asam klorogenat, trigonelin, karbohidrat, lemak, asam amino, asam organik, mineral dan aroma volatil. Kandungan pada kopi tersebut dapat menghasilkan efek aroma terapi. Minyak kopi layak untuk dijadikan kandidat sebagai bahan pengharum ruangan dengan aroma terapi. Sementara itu, kelompok petani kopi yang berada di Desa Sukorejo, Kecamatan Sumber Wringin memiliki permasalahan karena belum dapat memanfaatkan limbah biji kopi hasil sortasi dengan kondisi pecah, berlubang, biji yang terlalu muda dan terlalu tua. Oleh karena itu, teknologi pengolahan pascapanen diperlukan sehingga limbah biji kopi sortiran menjadi lebih bernilai ekonomis dan bermanfaat. Melalui program PPK 2019 ini, tim pelaksana kegiatan akan membantu mitra petani kopi untuk membuat produk olahan dengan bahan minyak kopi yang diekstrak dari limbah biji kopi robusta sortiran menjadi pengharum ruangan aroma terapi. Pengembangan produk pengharum ruangan dengan bahan kopi ini merupakan suatu langkah strategis dalam membantu mitra di Desa Sukorejo, Kecamatan Sumber Wringin, Kabupaten Bondowoso dalam menghadapi permasalahan limbah biji kopi sortiran yang belum dimanfaatkan dengan baik.

Abstract

Malaria and Dengue Haemorrhagic Fever (DHF) are two major tropical diseases in East Java. The pathogens of these diseases are transmitted to human hosts via haematophagy by vector mosquitoes. Anopheles spp. specifically transmits Plasmodium parasites which cause Malaria, while Aedes spp. transmits Dengue viruses that cause DHF. Bangsring, Banyuwangi is one of the endemic areas of Malaria, while Jember is one of endemic areas of DHF. Two species of Malaria vectors i.e Anopheles vagus and Anopheles sundaicus have been found from several samplings which were conducted in Bangsring region. This mosquitoes have been previously identified as a major vector for malaria. Aedes aegypti and Aedes albopictus, which were major vectors for DHF, have been easily found in Jember during our sampling for any season of the year. This research wanted to differentiate the morphological characteristic of those vectors for malaria and Dengue. Adult mosquitoes can be distinguished from one another by characterizing their morphological features. Palpi, wings, and legs characteristics are commonly used as determination keys in Anopheles sp., while thoraxes and legs characteristics are used as identification keys in Aedes sp. Morphological identification is considered as the basic necessity in understanding and determining bionomic of mosquito vector. This is very important in developing effective and efficient mosquito vector control strategies, which is also an important step to prevent the death risks associated with Malaria and DHF cases.

Abstract

Aedes albopictus mosquito is a potential vector for Dengue Haemorrhagic Fever (DHF) which transmits Dengue virus during blood feeding. The success of the blood feeding process is aided by the biological activity of proteins in the salivary glands of Aedes albopictus. There are 30 types of proteins from the salivary glands of Aedes albopictus which are carried along blood feeding process. Proteins in the salivary glands act as vasodilator and immunomodulator. Previous studies have identified two immunogenic proteins from the salivary glands of Aedes albopictus with molecular weight of 31 and 67 kDa. Further research on the biological function of these proteins requires its purified protein to better specify the target to developing a dengue vaccine. The objective of this study was to obtain 31 and 67 kDa purified proteins by implementation of electroelution and dialysis purification. The 31 and 67 kDa protein was successfully purified by this method. This has been confirmed by a single band visualization after SDS-PAGE analysis
