The toll type 4 (TLR4) receiver, a key model recognition receiver, initiates the innate immune response and leads to chronic and acute inflammation. In recent decades, the accumulation of evidence involved an inflammatory intervention mediated by the TLR4 in the regulation of the hypertrophic renovation of myocardium, indicating that the regulation of the TLR4 signaling path can be an effective strategy for the management of the physiopathology of Cardiac hypertrophy. Given the meaning of TLR4, it is imperative to examine the molecular mechanisms and roles underlying TLR4 signaling in cardiac hypertrophy. We examine here exhaustively the current knowledge of the TLR4 inflammatory response and its interaction ligands and co-receptors, as well as the activation of various intracellular signals.
We also describe the associated roles in promoting the secretion of infiltration of immune cells and the secretion of inflammatory mediators, which ultimately cause cardiac hypertrophy. Finally, we provide examples of some of the most promising medicines and new technologies that could mitigate the TLR4-mediated inflammatory response and prevent or reversed the results of winding heart hypertrophy. Porphyromonas Gingivalais MFA1 Fimbriae are considered to be adhesion factors and direct destruction of periodontal tissues, but their immunomodulatory actions are poorly understood. Here we have studied the effect of the stimulation of the MFA1 on the immunodevalent and metabolic mechanisms of gingival fibroblasts of periodontal connective tissue.
We also determined the toll (TLR) 2 and TLR4 receptor role in the recognition of the MFA1. MFA1 increased the expression of the coding genes of the chemokine (CXCL) 1, CXCL3, intercellular adhesion molecule (ICAM) 1 and selectin endothelium (E) in gingival fibroblasts, but did not have a significant effect on Genes that govern metabolism.
The toll receiver 2 at the crossroads between cancer cells, the immune system and the microbiota
The toll receiver 2 (TLR2) expressed on mediocre myeloid cells the recognition of harmful molecules belonging to invasive pathogens or to accommodate damaged tissues, resulting in inflammation. For this ability to activate immune responses, TLR2 has been considered an anti-cancer immunity player. As a result, TLR2 agonists were used as adjuvants for anticancer immunotherapy. However, the TLR2 is also expressed on neoplastic cells of different malignant tumors and promotes their proliferation thanks to the activation of the primary reaction protein of myeloid differentiation 88 (myd88) / Nuclear factor Kappa-light-chain-chain-valorization from the channel B activated (NF-κB). In addition, its activation on regulatory immune cells can contribute to the generation of an immunosuppressive microenvironment and the pre-metastatic niche, promoting the progression of cancer.
Thus, TLR2 represents a double-edge sword, whose role in cancer must be carefully understood for the configuration of effective therapies. In this review, we discuss diverging effects induced by the activation of TLR2 in different populations of immune cells, cancer cells and cancer stem cells. In addition, we analyze the stimuli that lead to its activation in tumor microenvironment, responding to the role of molecular patterns of danger, pathogen and microbiota and their modulation during cancer treatments. This information will contribute to the scientific debate on the use of TLR2 agonists or cancer treatment antagonists and pave the way for new therapeutic pathways.
Key Player in Cardiac Hypertrophy, Emphasizing the Role of Toll-Like Receptor 4
The type 7 receiver 7 is required for the development of self-immunization of lacrimal gland and type 1 diabetes in unplugged diabetic mice male
Sjögren Syndrome (SS) is an immunologically complex chronic autoimmune disease targeting lacrimal and salivary glands. Non obese diabetic mice spontaneously develop an inflammation of lacrimal and salivary glands with histopathological characteristics similar to SS in humans, including focal length infiltrates in the affected glands. Innés immune signals resulting in lymphocytic infiltration of these glands are not well defined. Here we evaluate the role of toll receptor (TLR) 7 in the development of SS-like manifestations in the nocturnal mice.
We have created a Knockout TLR7 hoche the deformation of the mouse and conducted histological and gene studies in order to characterize the effects of the TLR7 on the automatic self-immunity development. The TLR7 was necessary for a lacrymal gland inflammation specific to men but not for women’s salivary gland inflammation. In addition, TLR7 was required for the development of type 1 diabetes in male but non-female holed mice. The sequencing of the RNA has shown that the TLR7 was associated with an interferon response of type I (IFN) and a cell I cell response. IFN IFN in the lacrimal glands. Together, these studies identify a previously not appreciated pathogenic role for the TLR7 in lacrimal self-immunities and the development of the T1D in the manh mice Nok Simped to the growing set of evidence supporting sexual differences from self-immune disease mechanisms.
Description: Interleukin-18 (IL-18) has been identified as a molecule that induces IFN-Gamma production and enhances NK cell cytotoxicity. IL-18 receptor (IL-18R) is a type I membrane protein present in lung, leukocytes, spleen, liver, thymus, prostate, small intestine, colon, placenta and heart, and absent from brain, skeletal muscle, pancreas and kidney. IL-18R is present in Hodgkin s disease cell lines, and does not bind IL-1Alpha or IL-1beta. The association of IL-18 to IL-18R leads to activation of NFkB. At present two subunits of IL-18R have been characterized: IL-18RAlpha and IL-18Rbeta. IL-18RAlpha has been described as the ligand-binding chain and IL-18Rbeta as the signal-transduction chain.
