Abstract: Buffaloes are an important animal in the animal production system but it has been hampered by a number of problems like low conception rate, late sexual maturity, and susceptibility to diseases .in this context TLR4 is one of the most important components of the immune system which detects pathogenic microorganisms and initiates an immediate immune response. Earlier studies have revealed a sharp increase in TLR4 expression during the estrus phase hence, TLR4 can act as a biomarker for estrous detection and candidate marker for marker-assisted selection for the identification of diseases like mastitis in buffaloes. Major objectives of diagnostics and vaccines for veterinary or animal uses are to improve the health, production, and welfare of livestock species, increase cost-effective production of livestock, and prevent animal-human conflict in terms of disease transmission and other possible ways. Therefore, diverse approaches are needed for these seemingly different aims toward the development of estrous detection, immunodiagnostics, and vaccines. New and novel technologies linking immunology and the “-omics” techniques are required to usher in an era of great revolution towards understanding the diverse concepts and dynamics of immunology and systems biology. Computational epitope identification, design, and in silico pharmacology approaches are needed with the vast expansion of “-omics” data. The methodologies employing the structure-based epitope identification and antigen design have greater implications for the engineering of biomolecules with improved immunological properties and newer perspectives of structure-based rational design for the production of advanced immunoreagents.Summary: Buffaloes are valuable animals in animal production system as well as a major contributor to Indian economy but estrus detection had been a major bottleneck in their reproduction and management. In this context, TLR4 is one of the most important components of immune system which detects pathogen and initiates an immediate immune response. Earlier studies have revealed sharp increase in TLR4 expression during estrus phase hence, TLR4 was presumed as a biomarker for estrus identification.References: 1.
