Since the onset of COVID-19 pandemic, various severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants have emerged. Although primary site SARS-CoV-2 infection is lungs, it can also affect brain and induce neurological symptoms. However, specific effects different on remain unclear. In this study, a whole-transcriptome analysis was conducted using tissues K18-hACE2 mice infected with ancestral B.1 (Wuhan) variant major concern, including B.1.1.7 (Alpha), B.1.351 (Beta),...

HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic neuroinflammatory disease related to human T lymphotropic virus type 1 (HTLV-1) infection. Interferon III (IFN-λ), which includes IL28, IL29, and IL28R, affects the outcome of viral infections, might be complicated in progression HAM/TSP. Here, we investigated host-virus interactions manifestation HAM/TSP, using IL28B, HTLV-1 Tax, basic leucine zipper factor (HBZ), proviral load (PVL). The study groups consisted...

Abstract Background Vector-borne diseases (VBDs) represent an emerging global threat to public health due the geographical expansion of arthropod vectors. The study aims assess seroprevalence selected vector-borne pathogens (VBPs) in different groups outdoor workers and occupational risk factors for exposure bites. Methods A cross-sectional was conducted on 170 recruited two regions southern Italy, including farmers, forestry workers, veterinarians, geologists/agronomists administrative...

Human T-cell leukemia virus type I (HTLV-1) belongs to the delta retrovirus family and etiological agent of adult (ATL(. While current HTLV-1 therapy, relies on using Zidovudine plus IFN-γ, there is no FDA approved drugs against it. In silico drug repurposing a fast accurate way for screening US-FDA find therapeutic option infection. So that, this research aims analyze dataset antiviral as potential prospect an anti-viral Molecular docking simulation was performed identify interactions with...

Konjac glucomannan (KGM) is a water-soluble polysaccharide derived from the Amorphophallus's tuber and, as herbal medicine has shown, can suppress tumor growth or improve health. However, there been no investigation into effects of KGM on breast tumor-bearing mice. Therefore, in two cohort experiments, we assessed effect at daily doses 2 and 4 mg for 28 days dietary supplement also combination with lysate vaccine an adjuvant. Tumor volume was monitored twice weekly. In addition, TNF-α...

Human T-cell lymphotropic virus type 1 (HTLV-1) infection affects millions of individuals worldwide and can lead to severe leukemia, myelopathy/tropical spastic paraparesis, numerous other disorders. Pursuing a safe effective immunotherapeutic approach, we compared the viral polyprotein human proteome with sliding window approach in order identify oligopeptide sequences unique virus. The immunological relevance oligopeptides was assessed by searching them immune epitope database (IEDB). We...

Monkeypox is a zoonotic virus that has recently affected different countries worldwide. On July 23, 2022, the WHO declared outbreak of monkeypox as public health emergency international concern. Surveillance studies conducted in Central Africa 1980s and later during outbreaks same region showed smallpox vaccines to be clinically somewhat effective against virus. However, there no specific vaccine this This research used bioinformatics techniques establish novel multi-epitope candidate can...

Human T cell leukemia virus type-1 (HTLV-1) is the cause of adult leukemia/lymphoma (ATL), uveitis, and certain pulmonary diseases. In recent decades, many scientists have proposed development different treatment prevention strategies to combat HTLV-1 infection. this study, we used bioinformatics tools predict peptide protein vaccine candidates against that can potentially induce antibody production both CD4+ CD8+ immune responses. Five critical proteins, viz., Hbz, Tax, Pol, Gag, Env, were...

Background: Leukodystrophies constitute a heterogeneous group of inherited disorders primarily affecting the white matter central nervous system. Aminoacyl-tRNA synthetases (ARSs) catalyze attachment an amino acids to their cognate transfer RNAs (tRNAs). Pathogenic variants in both cytosolic and mitochondrial ARSs have been linked broad range neurological disorders, including hypomyelinating leukodystrophies pontocerebellar hypoplasias (PCH). Aminoacyl tRNA synthetase-interacting...

The human T-cell leukemia virus type 1 (HTLV-1) is a positive single-stranded RNA that belongs to the delta retrovirus family. As result, vaccine candidate can be recognized by B cells and T good for generating durable immune response. Further, GPEHT protein multi-epitope designed based on Gag, Pol, Env, Hbz, Tax proteins of HTLV-1. In developing suitable effective against HTLV-1, selection (GPEHT) with formulation an alum adjuvant was conducted. this study, we assessed potential stimulating...

Oral subunit vaccines are an interesting alternative strategy to traditional live-attenuated or inactivated for conferring protection against gut pathogens. Despite being safer and more cost-effective, the development of oral remains challenging due barriers imposed by gastrointestinal tract, such as digestive enzymes, a tolerogenic immune environment inability larger proteins cross epithelial barrier. Recent advances have focused on overcoming these using potent mucosal adjuvants...
