Molecular characterization of toll-like receptor 2 gene in Bikaneri camels (Camelus dromedarius)
Toll-like receptors (TLRs) are an important family of receptors constituting the first line of defense system. Tolllike receptors play crucial roles in the innate immune system by recognizing pathogen-associated molecular patterns derived from various microbes. Present investigation was carried out to characterize the coding sequence of TLR2 gene in Indian dromedary camels. Blood was collected from five Bikaneri camels and genomic DNA was isolated. Eight pairs of overlapping primers were designed for amplification of TLR2 gene coding region. All the fragments were successfully amplified using Polymerase chain reaction (PCR). The PCR products were purified and subjected to Sanger’s sequencing. TLR2 gene fragment of 3213 bp consisting of 2287 bp of coding sequence of exon 2 and 926 bp of 3’untranslated region (UTR) was successfully amplified. The sequence generated was submitted to the NCBI with accession number MW557315.1. The encoded amino acids codes for 12 leucine rich repeats (LRR) (Accession no. UBN09134.1). At the nucleotide level, the Bikaneri camels’ TLR2 gene showed highest similarity with camelids (99.30 to 99.59%) followed by vicugna pacos (97.54%). The nucleotide sequence similarity was lowest with Homo sapiens (82.37%). The amino acid sequence based phylogenetic tree revealed close relationship between camelid species followed by pig (86.2%), whereas human, gorilla, horse and donkey were distantly placed on the tree.
期刊介绍:
Articles published in The Indian Journal of Animal Sciences encompass a broad range of research topics in animal health and production related to cattle, buffalo, sheep, goat, camel, equines, pig, rabbit, yak, mithun, poultry and fisheries. Studies involving wildlife species and laboratory animal species that address fundamental questions about their biology will also be considered for publication. All manuscripts must present some new development and must be original, timely, significant and scientifically excellent. Papers will be rejected if standards of care of, or procedures performed on animals are not up to those expected of humane veterinary scientists. At a minimum, standards must meet the International Guiding Principles for Biomedical Research involving Animals, as issued by the Council for International Organizations of Medical Sciences. (C.I.O.M.S., c/o WHO, CH 1211 Geneva 27, Switzerland). Articles reporting new animal disease must follow GOI directive as given in detail in Guidelines to Authors.
