Abstract
There is an urgent need to find an effective therapy for life-threatening HTLV-1-associated diseases. Bitter melon (Momordica charantia) is considered a traditional herb with antiviral and anticancer properties and was tested in this study on HTLV-1 infectivity. GC-MS analyzed the alcoholic extract. In vitro assay was carried out using transfection of HUVEC cells by HTLV-1-MT2 cell line. The cells were exposed to alcoholic and aqueous extracts at 5,10, and 20 µg/mL concentrations. In vivo, mice were divided into four groups. Three groups were treated with HTLV-1-MT-2 cells as test groups and positive control, and PBS as the negative control group in the presence and absence of M. charantia extracts. Peripheral blood mononuclear cells (PBMCs), mesenteric lymph nodes (MLNs), and splenocytes were collected for HTLV-1-proviral load (PVL) assessment, TaqMan-qPCR. The GC-MS analysis revealed 36 components in M. charantia. The studies showed significant reductions in HTLV-1-PVL in the presence of extract in the HUVEC-treated groups (P = 0.001). Furthermore, the inhibitory effects of extracts on HTLV-1 infected mice showed significant differences in HTLV-1-PVL among M. charantia treated groups with untreated (P = 0.001). The T-cells in MLNs were significantly more susceptible to HTLV-1 than others (P = 0.001). There were significant differences among HTLV-1-infected cells in MLNs and splenocytes (P = 0.001 and 0.046, respectively). Also, aqueous and alcoholic extract-treated groups significantly affected HTLV-1-infected PBMCs (P = 0.002 and 0.009, respectively). M. charantia may have effective antiviral properties. The substantial compound of M. charantia could have inhibitory effects on the proliferation and transmission of HTLV-1 oncovirus.
期刊介绍:
The Journal of NeuroVirology (JNV) provides a unique platform for the publication of high-quality basic science and clinical studies on the molecular biology and pathogenesis of viral infections of the nervous system, and for reporting on the development of novel therapeutic strategies using neurotropic viral vectors. The Journal also emphasizes publication of non-viral infections that affect the central nervous system. The Journal publishes original research articles, reviews, case reports, coverage of various scientific meetings, along with supplements and special issues on selected subjects.
The Journal is currently accepting submissions of original work from the following basic and clinical research areas: Aging & Neurodegeneration, Apoptosis, CNS Signal Transduction, Emerging CNS Infections, Molecular Virology, Neural-Immune Interaction, Novel Diagnostics, Novel Therapeutics, Stem Cell Biology, Transmissable Encephalopathies/Prion, Vaccine Development, Viral Genomics, Viral Neurooncology, Viral Neurochemistry, Viral Neuroimmunology, Viral Neuropharmacology.
