Abstract

Indonesia has not conduct regular screening test of CMV infection due to the lack of seropositive prevelance data information. However, seronegative CMV results is not an indicator of safe blood for transfusion, so that another test that serves as confirmation test for CMV DNA is required. The aim of this study is to obtain prevalence data of CMV IgG antibody positive, the prevalence of CMV DNA positive and to determine the effect of CMV IgG titers against CMV DNA in blood donors in UTD PMI DKI Jakarta. Cross-sectional method was used to test 113 blood donor samples which have met inclusion criteria. Screening for CMV IgG antibody was held using indirect method chemiluminescence immunoassay (ChLIA) by Liason® XL 10050 Chemiluminescence Analyzer and CMV DNA analysis using qPCR method for the detection of CMV UL 54 with a tool Roche Light Cycler 480 II. Results indicate positive prevalence of IgG CMV in 111 samples (98.23%), and negative CMV IgG in 2 samples (1.77%). Prevalence of CMV DNA positive donors is one sample (0.88%), 112 negative CMV DNA samples (99.12%) and Fisher's test results {P (0.982)> α (0.05)} showed no significant association between CMV IgG status with CMV DNA. CONCLUSIONS: UTD DKI Jakarta has a high prevalence of CMV IgG with low prevalence of CMV DNA.

Abstract

Development of human immunodeficiency virus type 1 (HIV-1) vaccines and anti-retroviral treatmentis currently hindered by the lack of models representing prominent symptoms of HIV-1 infections seen in humans. Simian-human immunodeficiency virus (SHIV) was constructed to resolve the limitations of SIVmac model and has been used in nonhuman primate model ofviral infections, particularly infections by the close relatives of HIV-1. Macaca fascicularis and M. nemestrina are being developed as model HIV/AIDS, by using chimeric virus SHIV produced by replacing the nucleotide structure of cyclophilin A binding region, vif gene and nef of HIV-1 with cyclophilin A binding region, vif gene and nef from SIV. The research aims to study the model of HIV/AIDS on nonhuman primates PBMC in vitro using SHIV. In particular, the study aims to obtain information about the capability of SHIV replication in PBMC of M. fascicularis and M. nemestrina. Results showed a cytopathic effect (CPE) in the form of multinucleated giant cells and expression of p24 protein in PHA-stimulated PBMC cultures of M. fascicularis and M. nemestrina after SHIV infection. The conclusion of this study is that SHIV can infect PBMC M. fascicularis and M. nemestrina in vitro based on CPE and expression of p24 protein.

Abstract

Background: High mutation rates in HIV-1 could affect the accuracy of diagnostic tests. Therefore, recombinant antigen that has an immunodominant and conserved region from HIV-1 need to be developed to detect HIV-1 infection in Indonesia.Materials and methods: The recombinant antigens comprise of Gag (p24), Pol and Env (gp41). Each antigens was expressed in the Escherichia coli expression system and purified using Ni-NTA chromatography. The reactivity of purified antigen against HIV antibodies was tested against a group of 50 HIV-positive plasma samples and 45 HIV-negative plasma samples in a recombinant immunoblot assay (RIBA) platform test. Moreover, 21 of 50 HIV-positive samples and 3 of 45 HIV-negative samples were also tested using HIV blot 2.2 to compare RIBA with a commercial western blot kit. Ten HBV-positive and 10 HCV-positive plasma samples were used to check cross-reactivity with HIV recombinant proteins in RIBA.Results: All HIV-positive samples (100%) tested with RIBA were reactive towards Gag (p24), Pol, Env (gp41). Otherwise, 3 of 21 HIV-positive samples assayed with HIV blot 2.2 were not reactive to Pol protein. All HIV-negative samples tested with RIBA and 3 HIV-negative samples tested with HIV blot 2.2 did not produce any bands of HIV antigens. Few HBV and HCV samples showed reactivity towards HIV recombinant proteins.Conclusion: Each recombinant protein, Gag (p24), Pol, Env (gp41), could be expressed and purified, as well as had reactivity to HIV-positive samples in RIBA test. Therefore, RIBA can be used as a diagnostic test to detect HIV-1 infection in Indonesia.Keywords: diagnostic, HIV-1, immunodominant, recombinant immunoblot assay (RIBA)

Abstract

Cell-penetrating peptides (CPPs) are small peptides that can transfer other materials into a cellular compartment. In this research, we studied the effect of fusion of new CPPs to the N-terminal of enhanced Green Fluorescent Protein eGFP on the ability of the latter to fluoresce. Results showed that the recombinant protein CPPs-eGFP could be successfully expressed in Escherichia coli. In contrast to E. coli expressing wild-type eGFP, which could fluoresce under ultraviolet (UV) or visible light, E. coli expressing CPPs-eGFP lost their ability to fluoresce. PyMol, a molecular visualization system, revealed that fusion of the new CPPs to the N-terminal of eGFP alters interactions between chromophore-forming tripeptides and the adjacent amino acids of other tripeptides. Disrupting peptide interactions induced structural changes in eGFP that caused it to lose its fluorescence ability. We suggest performing computational analyses to predict the biological function of new fusion proteins prior to starting laboratory work.

Abstract

Biofilm is an aggregate of consortium bacteria that adhere to each other on a surface. It is usually protected by the exopolysaccharide layer. Various invasive medical procedures, such as catheterization, endotracheal tube installation, and contact lens utilization, are vulnerable to biofilm infection. The National Institute of Health (NIH) estimates 65% of all microbial infections are caused by biofilm. Periplasmic α-amylase (MalS) is an enzyme that hydrolyzes α-1, 4- glicosidic bond in glycogen, starch, and others related polysaccharides in periplasmic space. Another protein called hemolysin-α (HlyA) is a secretion signal protein on C terminal of particular peptide in gram negative bacteria. We proposed a novel recombinant plasmid expressing α-amylase and hemolysin-α fusion in pSB1C3 which is cloned into E.coli to enable α-amylase excretion to extracellular for degrading biofilm polysaccharides content, as in starch agar. Microtiter assay was performed to analyze the reduction percentage of biofilm by adding recombinant E.coli into media. This system is more effective in degrading biofilm from gram positive bacteria i.e.: Bacillus substilis (30.21%) and Staphylococcus aureus (24.20%), and less effective degrading biofilm of gram negative i.e.: Vibrio cholera (5.30%), Pseudomonas aeruginosa (8.50%), Klebsiella pneumonia (6.75%) and E. coli (-0.6%). Gram positive bacteria have a thick layer of peptidoglycan, causing the enzyme to work more effectively in degrading polysaccharides.

Abstract

Background The World Health Organization (WHO) recommends viral load (VL) monitoring for HIV patients on antiretroviral therapy (ART). However, availability of VL monitoring in low-income countries remains limited. Objective To investigate factors associated with virological failure in HIV-infected children treated without routine VL monitoring. Methods This cohort study was done in children living with HIV (CLHIV) registered at Cipto Mangunkusumo General Hospital from 2004 to 2021. Viral load monitoring was not routinely done. Subjects with at least one VL result after 6 months on ART were included in the study. Virological failure was defined as a VL of >1,000 copies. Subjects’ data were obtained from medical records, laboratory reports, and dispensing pharmacies. Statistical analysis was done following survival analysis with hazard ratio. Results There were 384 children who had at least 1 VL result after ART was initiated. Median age at diagnosis was 30 months. Length of follow-up ranged from 6 to 216 months, with a mean frequency of VL monitoring of 0.7 times/person/year. Most subjects were already in clinical stages 3 and 4 (77.8%); 75% met severe immunodeficiency criteria. Virological failure was found in 45.8% of subjects after a median of 33 months on first-line ART, yielding an incidence of 3.3 per 1,000 person months. Independent associated factors were age at diagnosis of <60 months (HR 1.714; 95%CI 1.13 to 2.6), severe immunodeficiency (HR 1.71; 95%CI 1.15 to 2.54), referral cases (HR 1.70; 95%CI 1.23 to 2.36), and WHO clinical staging 3 (HR 1.987; 95%CI 0.995 to 3.969) and 4 (HR 2.084; 95%CI 1.034 to 4.201). Subjects with virological failure had lower weight-for-age z-scores [median 1.92; interquartile range (IQR) -3.003 to -0.81] and height-for-age z-scores [median -2.05; IQR -2.902 to -1.04] at the time of failure. Conclusions In HIV-infected children treated without routine VL monitoring, age at diagnosis <60 months, severe immunodeficiency, WHO clinical stage 3 and 4, and referral from other centers were associated with virological failure.

Abstract

Background: Reprogrammed cell therapy has not been applied for clinical purposes due to the malignancy issue. The aim of this study was to design the recombinant vector of the transcription factors and analyze the effectiveness of cell-penetrating peptide delivering system for human primary fibroblast transfection to avoid the malignancy issue.Materials and methods: The constructions of CCAT/enhancer binding protein alpha (CEBPA), hepatocyte nuclear factor 4 alpha (HNF4A), nuclear receptor subfamily 1 group I member 2 (NR1I2) were confirmed with DNA digestion and sequencing. Breast reduction (BRED) and palate (PAL) tissue were used as human primary fibroblast sources. The transcription factors were delivered into BRED and PAL with recombination of avian leukosis sarcoma virus (ALSV), human immunodeficiency virus (HIV) matrix, and regulator of expression of virion proteins (Rev) (ALMR), tagged with enhanced green fluorescence protein (eGFP). Post-transfection cells were then cultivated with optimized medium. Gene expression was measured with quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR).Results: Gene expression levels of CEBPA, HNF4A, NR1I2, glutamate-ammonia ligase (GLUL), albumin (ALB), and cytochrome P450 (CYP) were increased. Transfection with ALMR, which were more efficient in BRED than PAL fibroblasts may have the advantage in autologous cell therapy for elderly patients.Conclusion: Transfection of transcription factors to human primary fibroblast may be performed by using constructions of plasmid as designed in this study.Keywords: recombinant plasmid, hepatocyte-like cells, primary fibroblasts, recombinant peptide, cell reprogramming, autologous cells therapy

Abstract

Among influenza viral proteins, hemagglutinin 1 (HA1) is the target for neutralizing antibodies which inhibit virus binding to receptor of target cells. This protein is widely developed as subunit recombinant vaccine. In this research, we expressed HA1 protein recombinant from DKI271/2011 Indonesian strain in Pichia pastoris. The identity of this protein was confirmed by western blotting using anti-His T ag and mouse specific antibody HA H1N1pdm09. The use of yeast P . pastoris as an alternative strategy to solve the problems which commonly found in influenza vaccine productions. Expression protein in E. coli has been known to have many problems, while mammalian and insect cells requires special skills and relatively high cost. The analysis of HA1 gene sequences showed no mutation in epitope region which recognized by T dan B cells. Further, this recombinant protein can be used as vaccine candidate in influenza vaccine development.Keywords: Hemagglutinin; Pichia pastoris; vaccine; Influenza Virus; H1N1pdm09.

Abstract

According to World Health Organization (WHO), Nipah virus is a type of infectious disease from 10 types of infectious diseases that can pose a risk to the public health. Besides, it has the potential to become a new pandemic. The State Intelligence Agency has the authority, mandate, and responsibility to actively engage in early detection of a disease that could potentially become an epidemic and cause a threat to national security and interests. The formulation of this research problem is " Threat Analysis of Nipah Virus as a New Pandemic from the Perspective of a Medical Intelligence." The authors used a qualitative descriptive method approach through interviews and literature studies related to Nipah virus research. The results of the research indicated that the Nipah virus has the potential to become a new pandemic that can threaten the Indonesian people health and even the world. Thus, early detection of the Nipah virus spreading in Indonesia is necessary, by collaborating across ministries in implementing preventive measures using a one health concept approach.
