The evolution of vertebrate Toll-like receptors

The evolution of vertebrate Toll-like receptors.

The complete sequences of Takifugu Toll-like receptor (TLR) loci and gene predictions from many draft genomes enable comprehensive molecular phylogenetic analysis. Strong selective pressure for recognition of and response to pathogen-associated molecular patterns has maintained a largely unchanging TLR recognition in all vertebrates. There are six major families of vertebrate TLRs. This reperto...

Pan-Vertebrate Toll-Like Receptors During Evolution

Human toll-like receptors (TLRs) recognize pathogen-associated molecular patterns (PAMPs) to raise innate immune responses. The human TLR family was discovered because of its sequence similarity to fruit fly (Drosophila) Toll, which is involved in an anti-fungal response. In this review, we focus on the origin of the vertebrate TLR family highlighted through functional and phylogenetic analyses...

The Role of Toll-Like Receptors in Breast Cancer

Breast cancer is highly prevalent worldwide. Treatment of this disease is a major global public health problem; therefore, numerous studies have explored new molecular profile helping for breast cancer therapy. Different risk factors are attributed to breast cancer; however, chronic inflammation and immune regulation are highly essential. Various molecules impact this context, including toll-li...

Ectodomain Architecture Affects Sequence and Functional Evolution of Vertebrate Toll-like Receptors

Toll-like receptors (TLRs) are crucial components of innate immunity that specifically recognize diverse pathogen-associated molecular patterns from pathogens. The continuous hydrogen-bond network (asparagine ladder) formed among the asparagine residues on the concave surfaces of neighboring leucine-rich repeat modules assists in stabilizing the overall shape of TLR ectodomains responsible for ...
