α-GalCer is a potent immunomodulatory molecule that is presented to NKT cells via the CD1 antigen-presenting system. We hypothesized that when used as an adjuvant α-GalCer would induce protective immune responses against Rhodococcus equi, an important pathogen of young horses. Here we demonstrate
Vesicular stomatitis (VS) virus causes an important clinical disease of cattle and horses in North America. In order for a vaccine to be useful in the control of VS, it must not only protect against disease, but allow ready differentiation of infected and vaccinated animals. In these studies, we
We have recently demonstrated that oncolytic vesicular stomatitis viruses can be efficiently and selectively delivered to neoplastic lesions by myeloid-derived suppressor cells (MDSCs). Importantly, the loading of viruses onto MDSCs inhibited their immunosuppressive properties and endowed them with
Cytosine-phosphate-guanosine (CpG-ODN) has been described as a potent immunostimulatory agent in different species. No study reported the effect of a P-class CpG when administered systemically in healthy horses. The aim of this study was to evaluate the tolerance and the effect of an intramuscularly
20 sarcoid-affected horses from a practice in the northern Jura were used in this experiment. The mean age of the 20 horses was 3.9 years at the time of the first observation of sarcoid tumors. On the average, 4.4 tumours were noted per horse. 10 of the horses were treated in a double-blind study
A 50% ethanolic extract of Picrorhiza kurroa Royle ex Benth. (Scrophulariaceae) leaves (PKLE) was found to stimulate the cell-mediated and humoral components of the immune system as well as phagocytosis in experimental animals. PKLE elicited a dose-related increase in SRBC, induced 4 h (early) and
Immunostimulatory gene therapy has been developed during the past twenty years. The aim of immunostimulatory gene therapy is to tilt the suppressive tumor microenvironment to promote anti-tumor immunity. Hence, like a Trojan horse, the gene vehicle can carry warriors and weapons into enemy territory
Inhalation of immunostimulatory bacterial DNA segments (cytosine-phosphate-guanosine-oligodeoxynucleotides, CpG-ODN) normalizes clinical and cytologic parameters in severe equine asthma. We hypothesized that CpG-ODN inhalation also reduces the misbalance of elastinolytic activity in The interest in understanding interaction between the toll-like receptor and the viral infection has increased because of its importance in disease control. Here we have cloned the porcine TLR7 (pTLR7) cDNA encoding for 1050 amino acids. The pTLR7 Exhibits 90, 87, 87, 86, 84 and 78% similarity to
Three moderately to broadly recognized equine infectious anemia virus (EIAV) peptides that contained helper T-lymphocyte (Th) 1 epitopes were previously identified. Although lipopeptide immunization was only weakly immunostimulatory in a preliminary study, as measured by T-lymphocyte proliferation
Significant advances have been made in delineating the structure and function of the clinically important aeroallergens. Most have now been characterized at the molecular level, and their endogenous function determined. In the period of review, however, several novel allergens have been identified.
An immunostimulatory antigen specific factor (ASF) was found to be secreted by antigen-pulsed macrophages. Macrophages obtained from peritoneal exudate of C57BL/6 mice were pulsed with horse spleen ferritin (HSF). The PM10 ultrafiltration membrane-retained supernatant from the cultures of these
Antilymphocyte globulin is an immunoglobulin preparation prepared from heterologous serum after the animal (horse or rabbit) has been immunised with human lymphocytes, obtained from the thymus (antithymocyte globulin, ATG) or thoracic duct (antilymphocyte globulin, ALG). The rationale for the use of
