M. BAGHERI; R MIRAIE- ASHTIANI; M MORADI-SHAHRBABAK; A PAKDEL; A NEJATI-JAVAREMI

Volume 44, Issue 2 , August 2013, Pages 141-148

http://dx.doi.org/10.22059/ijas.2013.35563

Abstract
  The Toll-like Receptor 4 (TLR4) is an innate immune protein on cell surfaces that identifies Lipopolysaccharide (LPS) of gram-negative bacteria. Genetic markers associated with innate responses during mastitis could help in selection of cattle to improve disease resistance. The objective of this study ...  Read More
