The family of Toll-like receptors (TLRs) function as pattern-recognition receptors (PRRs) that respond to a myriad of highly conserved ligands. These substrates include pathogen-associated molecular patterns (PAMPs) for the recognition of invading pathogens, as well as damage-associated molecular patterns (DAMPs) for the recognition of endogenous tissue injury. While the functions of TLRs are d...

Toll-like receptors (TLRs) are important players in B-cell activation, maturation and memory and may be involved in the pathogenesis of B-cell lymphomas. Accumulating studies show differential expression in this heterogeneous group of cancers. Stimulation with TLR specific ligands, or agonists of their ligands, leads to aberrant responses in the malignant B-cells. According to current data, TLR...

Oral lichenoid reactions (OLRs) are chronic inflammatory lesions induced by contact with allergens. Toll-like receptors (TLRs) are members of pattern-recognition receptor superfamily. Once activated, TLRs induce production of cytokines and chemokines, thus leading to inflammatory reaction in host tissue. In the present study, we aimed to investigate the potential role of TLRs in the initiation ...

Interleukin-1 receptor family members (ILRs) and toll-like receptors (TLRs) are characterized by the presence of a conserved intracellular domain and the toll-IL-1resistance (TIR) domain and are key players in immunity and inflammation. ILR and TLR signaling is tightly regulated at different levels. All cell types of the innate immune system express ILRs and TLRs. In addition, IL-1 family membe...

Vechur cattle, an indigenous breed of Kerala and it is the smallest cattle in world. They are highly disease resistant. The occurrence mastitis very Rare this as compared to crossbred cattle. Rearing these more cost effective they require less feed. Therefore, characterisation factors involved immune system breeds might provide insight into mechanisms variation resistance. Toll-like receptors (...

Background: Toll-like receptors (TLRs) detect diverse pathogen-associated molecular patterns and play a critical role in the innate immune response. Hosts should activate TLR-signaling pathways to eliminate invading pathogens. However, excessive activation of these pathways may interrupt immune homeostasis, leading to several diseases. Therefore precise regulation of TLR-signaling pathways is e...

Toll-like receptor (TLR) signaling has been implicated in the inflammatory responses in intestinal epithelial cells (IECs). Such inflammatory signals mediate complex interactions between commensal bacteria and TLRs and are required for IEC proliferation, immune response, repair, and homeostasis. The upregulation of certain TLRs in colorectal cancer (CRC) tissues suggests that TLRs may play an e...

background one-third of the world’s population is infected with mycobacterium tuberculosis. investigation of toll-like receptors (tlrs) has revealed new information regarding the immunopathogenesis of this disease. toll-like receptors can recognize various ligands with a lipoprotein structure in the bacilli. toll-like receptor 2 and tlr-4 have been identified in association with tuberculosis in...

On microbial invasion, the host immediately evokes innate immune responses. Recent studies have demonstrated that Toll-like receptors (TLRs) play crucial roles in innate responses that lead not only to the clearance of pathogens but also to the efficient establishment of acquired immunity by directly detecting molecules from microbes. In terms of intracellular TLR-mediated signaling pathways, c...
