Background: Endometriosis is a complex disease that profoundly affects the quality of life in many women. This disease affects roughly one in ten women of reproductive age. Endometriosis induces a variable amount of inflammatory reaction in pelvic environment. An active immune system needs to recognize these inflammatory agents. Rapid innate immune system defenses against infections involve the...

it has been suggested that single nucleotide polymorphisms (snps) in genes involved in toll-like receptors (tlrs) pathway may exhibit broad effects on function of this network and might contribute to a range of human diseases. however, the extent to which these variations affect tlr signaling is not well understood. in this study, we adopted a bioinformatics approach to predict the consequences...

the toll like (family of receptors tlr) are expressed primarily by immune cells and are known to be part of innate immune system. in the past decade involvement of tlrs in several physiologic and pathologic pathways has been proved. pain transmission via glial activation is one of such interesting fields. both pathological pain states and treatment have also been shown to be related to tlr-rela...

The innate immune system is an evolutionally conserved host defense mechanism against pathogens. Innate immune responses are initiated by pattern recognition receptors (PRRs), which recognize microbial components that are essential for the survival of the microorganism. PRRs are germline-encoded, nonclonal, and expressed constitutively in the host. Different PRRs react with specific ligands and...

Natural killer (NK) cells are specialized lymphocytes primarily involved in the response to infection and tumors. NK characterized by presence of specific surface molecules, as well a wide repertoire receptors that impart microenvironment‑dependent effector functions. Among these receptors, Toll‑like (TLRs) can be activated condition either cytotoxic or immunoregulatory phenotype. However, cell...

Abstract The mast cells, as located in the skin’s dermal layer, are important innate immune cells that mediate inflammation a defense response against outer pathogens. Mast activated by receptors such Toll-like receptrs (TLRs) and interact with variety of including keratinocytes. This study confirmed effect TLRs-stimulated on migration keratinocytes residing epidermis. HaCaT human keratinocyte ...

Several plant lectins are known as potent immunomodulatory agents, and they are applied in different experimental models of infection (Afonso-Cardoso et al., 2011; Oliveira et al., 2013). Recent research has characterized these proteins as potential agonists of Toll-like receptors (TLRs or TLR), a family of mammalian homologs of Drosophila Toll protein involved in the detection of microbes and ...

Toll-like receptors (TLRs) play crucial roles in the induction of innate immune responses by recognising pathogen-associated molecular patterns. The engagement of TLRs by pathogens results in induction of co-stimulatory molecules that facilitate a specific immune response and also in the induction of pro-inflammatory proteins that will promote the elimination of pathogens from the body. TLRs em...

Macrophages play diverse roles including but not limited to homeostatic clearance, detection of invading pathogens and induction of the adaptive immune response. Since their discovery, it has become clear that Toll-like receptors (TLRs) can play a major role in these macrophage functions. This review will describe the TLRs, their signalling pathways and their role in macrophage function.

Tumors arise and progress in immunocompetent hosts presumably by activating tolerance mechanisms critical for normal homeostasis. Host immune cells can mount anti-tumor responses by activation of Toll-like receptors (TLRs). However, emerging data suggests that molecules that negatively regulate TLRs are exploited by tumors to induce tolerance and mitigate the host immunosurveillance. Targeting ...
