Abstract

HPV merupakan kelompok virus penyebab kanker serviks. HPV16 menyebabkan 46-63% karsinoma sel skuamosa serviks. HPV16 terdiri dari 3 region siklus sel, yaitu early region (E), long control region (LCR), dan late region (L). Early region yang berasal dari protein E1, E2, E4, E5, E6, dan E7 berperan dalam ekspresi gen virus, replikasi virus, dan siklus hidup virus. Virus akan mengekspresikan protein E1 dan E2 kemudian terjadi delesi, dan sel yang terinfeksi akan berdiferensiasi dan mengekspresikan E6 dan E7. Ekspresi E6 dan E7 akan menurunkan ekspresi TLR9, IFN-1, dan supresi sitokin proinflamasi. Respons imun yang menurun menyebabkan sel yang terinfeksi berdiferensiasi menjadi sel kanker. Vaksinasi profilaksis digunakan sebagai pencegahan dan pengendalian infeksi virus HPV16, tetapi tidak dapat melindungi individu yang sudah terinfeksi dari perkembangan infeksi virus dan sel abnormal. Oleh karena itu, vaksinasi terapeutik diperlukan untuk imunoterapi kanker. Antigen HPV16 yang terdiri dari E2, E6, dan E7 diharapkan menjadi target yang baik. Antigen E2, E6, dan E7 bertujuan untuk mengaktifkan respons imun spesifik yang diperantarai sel untuk memfagositosis sel yang terinfeksi. Antigen diproses oleh sel dendritik dan kemudian disajikan kepada molekul MHC. MHC II akan merangsang respons sel T CD4+ terhadap protein yang akan membantu sel T CD8+ sitotoksik. Antigen disajikan oleh MHC I untuk dipresentasikan ke sel T CD8+ sitotoksik untuk mengeliminasi sel yang terinfeksi. Antigen E2, E6, dan E7 untuk imunoterapi guna mencegah perkembangan sel abnormal sehingga tidak berkembang menjadi kanker.

Abstract

Lower respiratory tract, sepsis, or urinary tract infection caused by the multidrug resistance Pseudomonas aeruginosa is common in the hospital, especially in the ICU wards. The treatment against this bacteria requires combination of antibiotics with different mechanism of actions. In this study, several combinations of antibiotics were evaluated in vitro against carbapenem-resistant P. aeruginosa isolated from the ICU of Cipto Mangunkusumo Hospital. The combination of antibiotics tested were ceftazidime-amikacin, ceftazidime-ciprofloxacin, and ciprofloxacin-amikacin. Checkerboard assay to the combination of antibiotics was conducted to assess the in vitro synergistic activity. A total of 22 P. aeruginosa isolates were collected, 16 of them were resistant to ceftazidime, ciprofloxacin, amikacin, as well as carbapenem. The result revealed that the combination of ceftazidime and amikacin showed promising synergistic activity. Conversely, no synergitic activities were shown by the combination of ceftazidime-ciprofloxacin and ciprofloxacin-amikacin. The combination of ceftazidime-amikacin may has potential effect againsts carbapenem-resistant P. aeruginosa in vitro.

Abstract

The mRNA expression system has revolutionised biotechnology, notably in viral mRNA vaccine development, cancer immunotherapy, and gene therapy. However, recent safety concerns regarding the COVID-19 mRNA vaccine have emerged, particularly regarding its rare adverse effects and its possible connection to cancer. This review explains several approaches used in developing viral mRNA vaccines, the past obstacles solved in generating the current COVID-19 mRNA vaccine, and finally the current advancements and ongoing challenges in the viral mRNA vaccine field. We particularly focus on strategies and methods to improve the safety and translation efficiency of the mRNA vaccine, such as enhancing the vaccine’s transfection specificity to targeted dendritic cells (DC) and using viral IRES or self-amplifying mRNA format to improve mRNA translation efficiency.

Abstract

ABSTRAK Kanker serviks atau kanker mulut rahim merupakan salah satu penyebab kematian tinggi sampai saat ini. Kanker ini dikaitkan dengan infeksi Human Pappiloma virus (HPV). Vaksinasi merupakan salah satu metode pencegahan yang cukup efektif untuk mencegah kanker serviks. Vaksin yang beredar saat ini efektif untuk mencegah infeksi HPV, namun kurang efektif jika diberikan pada orang yang telah terinfeksi. Hal tersebut dikaitkan dengan jalur kekebalan tubuh yang diinduksi oleh vaksin tersebut. Dalam penelitian ini dirancang antigen HPV 16 yang dapat digunakan dalam pengembangan vaksin terapetik yang ditujukan untuk meningkatkan respon kekebalan seluler yand secara spesifik dapat menghancurkan sel kanker servik. Pemilihan dan karakterisasi antigen dilakukan dengan menerapkan Bioinformatika. Parameter yang dinilai antara lain kemampuan antigen diproses dan dipresentasikan oleh sel tubuh pada sel kekebalan tubuh yang bertanggung jawab pada eliminasi sel kanker, yaitu sel CD8. Hasil studi menunjukkan diperoleh epitop CD8 yang dikenali oleh beberapa jenis HLA. Bioinformatika dapat digunakan untuk mencari epitop.

Abstract

Introduction: Peptides with specific affinity toward breast cancer stem cells (BCSCs), including GYSASRSTIPGK and GAIRIRLSEPLS, have gained interest in targeted cancer diagnostics; however, the low abundance of BCSCs often results in limited detection sensitivity. This study addresses this limitation by conjugating BCSC-specific peptides to self-assembling Human Papillomavirus (HPV16) L1 protein, resulting in virus-like particles composed of 72 pentamers that provide substantial signal amplification. In addition, the SpyTag–SpyCatcher system derived from the Streptococcus pyogenes CnaB2 domain provides a robust strategy to enhance peptide–protein stability. Objectives: This study aimed to express and purify three recombinant proteins as key components for assembling a BCSC-specific diagnostic construct: HPV16 L1–SpyTag, SpyCatcher–GYSASRSTIPGK, and SpyCatcher–GAIRIRLSEPLS. Methods: Recombinant genes encoding the target proteins were expressed in Escherichia coli (E. coli) BL21(DE3) following IPTG induction for 1–4 hours. Bacterial cells were harvested and lysed under native or denaturing conditions, and recombinant proteins were purified using Ni-NTA affinity chromatography. Results: SDS–PAGE analysis showed clear bands at the expected molecular weights for HPV16 L1–SpyTag (58.5 kDa), SpyCatcher–GYSASRSTIPGK, and SpyCatcher–GAIRIRLSEPLS (~15 kDa), with induction-dependent increases in band intensity. The SpyCatcher–peptide fusions were predominantly soluble and purified under native conditions, whereas HPV16 L1–SpyTag was largely insoluble and required denaturing purification. Conclusion: HPV16 L1–SpyTag and SpyCatcher–peptide fusions were successfully expressed and purified in E. coli, establishing a versatile platform with potential to enhance BCSC-targeted detection and treatment strategies in breast cancer.
