				Abstract 
 
				
				
				Aim: 
				
				To study the effect of 
				
				Staphylococcus aureus 
				
				cell wall antigens, peptidoglycan (PGN) and lipoteichoic acid (LTA) 
				challenge on immune cells present in bovine peripheral blood 
				mononuclear cells (PBMCs). 
				
				
				Materials and Methods: 
				
				In this study, efforts have been made to investigate the effects 
				of three combinations (10+10, 20+20 and 30+30 μg/ml) of PGN and 
				LTA obtained from 
				
				S. aureus. 
				These antigens were used to challenge the bovine PBMCs. After 6 
				h of incubation quantitative, real time-polymerase chain 
				reaction was used to study toll-like receptor 2 (TLR-2) and 
				major cytokine mRNA expression in bovine PBMC challenged with 
				three different antigen blends. 
				
				
				Results: 
				
				The results indicated that mRNA level of interferon gamma is 
				influenced by the expression of TLR-2 gene. Tumor necrosis 
				factor-alpha (TNF-α), 
				interleukin 10 (IL-10), and IL-8 genes showed a maximum response 
				at a dose of 10 μg of PGN and 10 μg of LTA challenge per ml of 
				culture medium. The outcome also suggests that both IL-10 and 
				IL-8 followed the expression pattern of TNF-α. 
				
				
				Conclusion: 
				
				A dose of 10 μg of PGN and 10 μg of LTA per ml of culture medium 
				was found to be most suitable for challenging PBMC. 
				
				Keywords: 
				
				expression, lipoteichoic acid, mastitis, peptidoglycan, 
				peripheral blood mononuclear cell.
