The ability of the immune system to recognize molecules that are broadly shared by pathogens is, in part, due to the presence of immune receptors called toll-like receptors (TLRs) that are expressed on the membranes of leukocytes including dendritic cells, macrophages, natural killer cells, cells of the adaptive immunity T cells, and B cells, and non-immune cells (epithelial and endothelial ...
Toll-like receptor 1 (TLR1) is a member of Toll-like receptors (TLRs), which is a family of pattern recognition receptors (PRRs) that form the cornerstone of the innate immune system. [5] [6] [7] TLR1 recognizes bacterial lipoproteins and glycolipids in complex with TLR2. TLR1 is a cell surface receptor. [5]
One type of PRR is a group of integral membrane glycoproteins called toll-like receptors (TLRs), which can recognize certain lipoproteins, peptidoglycan, CpG-rich DNA, and flagellar components in bacterial cells, as well as glycoproteins and phospholipids from protozoan parasites and conidia (fungal spores).

Members of the very wide interleukin-1 receptor (IL-1R) family are characterized by extracellular immunoglobulin-like domains and intracellular Toll/Interleukin-1R (TIR) domain. It is a group of structurally homologous proteins, conserved throughout the species as it was identified from plants to mammals.
Toll-like receptor 9 is a protein that in humans is encoded by the TLR9 gene. [5] TLR9 has also been designated as CD289 ( cluster of differentiation 289). It is a member of the toll-like receptor (TLR) family.
Cluster of differentiation CD14 is a receptor for a very wide range of microbial products including lipopolysaccharide (released from Gram-negative bacteria), peptidoglycans, and lipoteichoic acid (constituents of Gram-positive bacteria).

Well, according to Wise, the brain is actually the most powerful sex organ there is—namely because genital stimulation produces so much muscle and nerve information that a tremendous boost in ...
TLR4 belongs to the toll-like receptor family which is representative of the pattern recognition receptors (PRR), so named for their ability to recognize evolutionarily conserved components of microorganisms (bacteria, viruses, fungi and parasites) called pathogen-associated molecular patterns (PAMPs). The recognition of a PAMP by a PRR ...
