الدراسة الحالية تركز على مستقبلات مناعية معينة تدعى مستقبلات الشبيهة بمستقبلات تول (TLRs)؛ يمكن لهذه المستقبلات تحديد أنماط جزيئية محددة في مسببات الأمراض، وبالتالي القضاء عليها. في هذه الدراسة نقوم بتحديد العلاقة المرضية بين هذه المستقبلات ومرض اعتلال شبكية السكري (DR). هذا المرض من مضاعفات مرض السكري، تؤثر على الأوعية الدموية الصغيرة في شبكية العين ويمكن أن تؤدي إلى العمى. لقد أردنا في هذا البحث التحقق من مساهمة المستقبلات الشبيهة بمستقبلات تول4 (TLR4… 



Lack of Toll-like receptor 4 or myeloid differentiation factor 88 reduces atherosclerosis and alters plaque phenotype in mice deficient in apolipoprotein E.

An important role for TLR4 and MyD88 signaling in atherosclerosis in a hypercholesterolemic mouse model is suggested, providing a pathophysiologic link between innate immunity, inflammation, and atherogenesis.

Cutting Edge: A Novel Toll/IL-1 Receptor Domain-Containing Adapter That Preferentially Activates the IFN-β Promoter in the Toll-Like Receptor Signaling1

Findings suggest that TRIF is involved in the TLR signaling, particularly in the MyD88-independent pathway.

Toll-Like Receptor 4 Deficiency Decreases Atherosclerosis But Does Not Protect Against Inflammation in Obese Low-Density Lipoprotein Receptor–Deficient Mice

Whether TLR4 deficiency has a protective role in inflammation, insulin resistance, and atherosclerosis induced by a diabetogenic diet is investigated and alternative pathways may be responsible for adipose tissue macrophage infiltration and insulin resistance that occurs in obesity.

Cutting edge: Toll-like receptor 4 (TLR4)-deficient mice are hyporesponsive to lipopolysaccharide: evidence for TLR4 as the Lps gene product.

It is demonstrated that TLR4 is the gene product that regulates LPS response, and a single point mutation of the amino acid that is highly conserved among the IL-1/Toll receptor family is found.

Hyperglycemia Induces Toll-Like Receptor-2 and -4 Expression and Activity in Human Microvascular Retinal Endothelial Cells: Implications for Diabetic Retinopathy

The novel data suggest that hyperglycemia induces TLR-2 andTLR-4 activation and downstream signaling mediating increased inflammation possibly via reactive oxygen species (ROS) and could contribute to DR.

RNA interference-mediated inhibition of TLR2 and MyD88 expression in C2C12 muscle cells resulted in a near complete inhibition of palmitate-induced insulin resistance and interleukin (IL)-6 production.

Endogenous ligands of Toll‐like receptors

It is essential that efforts should be directed to conclusively determine whether the reported putative endogenous ligands of TLRs are a result of the endogenous molecules or of contaminant(s), before exploring further the implication and therapeutic potential of these putative TLR ligands.

Mal (MyD88-adapter-like) is required for Toll-like receptor-4 signal transduction

A protein is described, Mal (MyD88-adapter-like), which joins MyD88 as a cytoplasmic TIR-domain-containing protein in the human genome, which is therefore an adapter in TLR-4 signal transduction.

Essential role for TIRAP in activation of the signalling cascade shared by TLR2 and TLR4

The results show that TIRAP has a crucial role in the MyD88-dependent signalling pathway shared by TLR2 and TLR4, and is not specific to TLR3, TLR7 or TLR9 signalling, which is in contrast to previous suggestions.
