Toll-like receptors in teleosts
نویسندگان
چکیده
Toll-like receptors (TLR) recognize the pathogen-associated molecular patterns (PAMPs) and regulate the subsequent immune responses in mammals. We have so far succeeded in finding the 11 types of TLR genes from Japanese flounder (Paralichthys olivaceus). TLR genes have also been found in the genomes of fugu (Takifugu rubripes) and zebrafish (Danio rerio). However, only limited information is known about the function of TLRs in fish. The fragmentary information of the fish TLR gene expression, immune response following PAMPs stimulation and intracellular signaling are available in fish. In addition, the phylogenetic analysis in vertebrate TLR genes and comparison of TLR family members between teleost fish species revealed that specific divergence of TLR genes between mammals and fish as well as between fish species. Here, the possible functions of teleost fish TLR and its importance are discussed.

Introduction: Toll-Like Receptors (TLRs) are members of pattern recognition receptors that recognize various molecules, including pathogen-associated molecular patterns and dead-associated molecular patterns. These receptors are expressed by immune, non-immune, and tumor cells. Some TLRs are implicated in tumor progression, while others are involved in tumor suppression. Our study aimed to eval...

Background: The pathogenesis of inflammatory bowel disease is complex and multifactorial. Studies have led to the current concept that Toll-like receptors represent key mediators of innate host defense in the intestine, and they are involved in maintaining mucosal as well as commensal homeostasis. We studied the possibility of simvastatin and antagonist of receptors of interleukin-1 for pharmac...

Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...
