WebIndividual TLRs recognize distinct pathogen-associated molecular patterns (PAMPs). The TLR family harbors an extracellular leucine-rich repeat (LRR) domain as well as a cytoplasmic domain that is homologous to that of interleukin-1 receptor (IL-1R). WebThe primary functions of the LRRs, where these are well-defined, are to recognize Pathogen-Associated Molecular Patterns (PAMPs), a process that can involve homo- or heterodimerisation and coreceptor binding. Receptor ligation and activation brings multiple transmembrane helices and cytoplasmic TIRs together (Fig. 1).

WebPathogens are recognized by a variety of immune cells, such as macrophages and dendritic cells, via pathogen-associated molecular patterns (PAMPs) on the pathogen surface, which interact with complementary pattern-recognition receptors (PRRs) on the immune cells' surfaces.

WebUpon pathogen attack, PRRs recognize pathogen-associated molecular patterns (PAMPs) via ectodomain and lead to signaling cascade via cytoplasmic kinase domain. PAMP-triggered immunity (PTI) activates basal defense responses sufficient to confer broad-spectrum disease resistance by inhibiting pathogen entry and growth.
