Bovine leukemia virus (BLV) is associated with enzootic bovine leukosis and is closely related to human T cell leukemia virus (HTLV). The cytotoxic T lymphocyte (CTL) plays a key role in suppressing the progression of disease caused by BLV. T and B cell epitopes in BLV have been studied, but CD8(+) CTL epitopes remain poorly understood. We used a library of(More)
The accumulation of inbreeding and the loss of genetic diversity is a potential problem in the modern swine breeds in China. Therefore, the purpose of this study was to analyze the pedigrees of Chinese Duroc (CD), Landrace (CL) and Yorkshire (CY) swine to estimate the past and current rates of inbreeding, and to identify the main causes of genetic diversity(More)
A bovine myeloid antimicrobial peptide (BMAP-28) is a member of the cathelicidin family which is included in the innate immune system of mammals. Recently, there have been many studies about antimicrobial peptides. This study aims to clarify whether BMAP-28 has bactericidal activity against methicillin-resistant Staphylococcus aureus (MRSA) and compares its(More)
The cathelicidin family is one of the several families of antimicrobial peptides (AMPs). A bovine myeloid antimicrobial peptide (BMAP-28) belongs to this family. Recently, the emergence of drug-resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) has become a big problem. AMPs are expected to be leading compounds of new antibiotics(More)
Epigallocatechin gallate (EGCG) is the major polyphenolic compound of green tea. Polyphenolic compounds were extracted from the leaf of Camellia sinensis (Japanese green tea), and the minimum inhibitory concentration against canine oral bacteria was measured. Subsequently, we investigated the inhibitory effects of polyphenolic compounds and EGCG on the(More)
The bovine leukemia virus (BLV) is the etiological agent of enzootic bovine leucosis (EBL) which is the most common neoplastic disease of cattle. Recent studies show bovine leukocyte antigen (BoLA)-DRB3 gene plays a direct role in controlling the number of proviral load in cattle and the homozygote BoLA-DRB3*1601 is associated with high proviral load. The(More)
Leptospiral lipopolysaccharide (L-LPS) has shown potency in activating toll-like receptor 2 (TLR2) in pig fibroblasts (PEFs_NCC1), and causes the expression of proinflammatory cytokines. However, the stimulation by L-LPS was weak eliciting the function of TLR2 sufficiently in pig innate immunity responses during Leptospira infection. In this study, the(More)
Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leukosis, the most common neoplastic disease of cattle. BLV is closely related to human T cell leukemia virus. B cell epitopes are important for the use of antibodies as therapeutic agents, the epitope-driven vaccine design, and immunological assays. A common B cell epitope for BLV has(More)
The bovine leukemia virus (BLV), a retrovirus structurally and functionally related to the human T-lymphotropic viruses HTLV-1 and HTLV-2, is the etiological agent of bovine leucosis. B cell immune mechanisms may play a major role in protection against BLV infection. A battery of 157 synthetic peptides, 15-mer length, 4 amino acids overlapped, was used to(More)
Bovine leukemia virus (BLV), the aetiological agent of the enzootic bovine leukosis, was widely spread in the worldwide , and it is desired to develop vaccine. However, the disease progression is greatly affected by host factors, and the difference of disease susceptibility is caused the reason to make hard to estimate the BLV vaccine effect. In this study,(More)
