TLRs encompass type I transmembrane proteins, comprising an ectodomain with leucine-rich repeats (LRRs) responsible for PAMP recognition, transmembrane regions, and the cytoplasmic Toll-interleukin (IL)-1 receptor (TIR) domains that activate downstream signaling pathways. 8 TLRs are classified into cell surface and endosomal subfamilies. Cell surface TLRs (TLR1, TLR2, TLR4, and TLR5) recognize ...

Kagan and Fitzgerald comprehensively review the functions and mechanisms of Toll-like receptors (TLRs), which are crucial detectors of microbial biomolecules and mediators of cellular immunity. They synthesize the overarching themes that have emerged from TLR signaling but are repeated throughout the pattern recognition receptor (PRR) superfamily.

Toll-like receptors and their induced signaling networks play critical roles in development and innate immunity, and have been studied in detail in a broad range of organisms in the past decades. However, comparative studies regarding this tremendous signaling system and the evolutionary pattern scenario across Animalia are limited.
Toll-like receptors (TLRs) are vital components of the innate immune system, serving as the first line of defense against pathogens by recognizing a wide array of molecular patterns. This review summarizes the critical roles of TLRs in immune surveillance and disease pathogenesis, focusing on their structure, signaling pathways, and implications in various disorders.
This review attempts to cover the implication of the toll-like receptors (TLRs) in controlling immune functions with emphasis on their significance, function, regulation and expression patterns. The tripartite TLRs are type I integral transmembrane receptors that are involved in recognition and conveying of pathogens to the immune system.
It is with this idea in mind that Toll-like receptors (TLRs) have emerged as a focal-point of biomedical research, as this small family of proteins serves as one of the earliest determinants of immune activation. In this review, we provide a comprehensive exploration of the ways that immunity and host physiology are influenced by TLRs.
Mammals have several distinct classes of PRRs including Toll-like receptors (TLRs), RIG-I-like receptors (RLRs), Nod-like receptors (NLRs), AIM2-like receptors (ALRs), C-type lectin receptors (CLRs), and intracellular DNA sensors such as cGAS (2, 3). Among these, TLRs were the first to be identified, and are the best characterized.
Toll-like receptors (TLRs) are well-defined pattern recognition receptors responsible for pathogen recognition and induction of innate immune responses. ... This review provides an overview of TLR signaling pathways and their regulators and discusses how TLR signaling, directly and indirectly, regulates cell-mediated immunity. In addition, we ...

Abstract Toll-like receptors (TLRs) are transmembrane proteins that detect invading pathogens by binding conserved, microbially derived molecules and that induce signaling cascades for proinflammatory gene expression. A critical component of the innate immune system, TLRs utilize leucine-rich-repeat motifs for ligand binding and a shared cytoplasmic domain to recruit the adaptors MyD88, TRIF ...
