Abstract:
Diabetes mellitus (DM) is a disease with constellation of metabolic aberrations resulting in debilitating complications. The prevalence of DM worldwide was 2.8% (171 million people) in 2000 and estimated to be at 4.4% (366 million people) in 2030. DM is a major risk factor for heart, kidney diseases, and lower limb amputations. Emerging in vitro and in vivo data suggest that systemic inflammation plays a role in the pathogenesis of DM complications via innate immune receptors. Toll-like receptors (TLRs) are key innate immune receptors that mediate the inflammatory responses in DM. There are no reviews that collectively summarize and examine the detrimental role of TLRs in the manifestation of DM complications namely heart disease, nephropathy, neuropathy, and wound healing. Thus, in this review, we will provide summaries of the TLR expression and activation and elucidate their role in propagating inflammation seen in DM complications.
Insights
Toll-like receptors (TLRs) drive inflammation, worsening diabetes mellitus (DM) complications like heart disease and kidney issues. This review examines TLRs
Area of Science:
- Immunology
- Endocrinology
- Pathophysiology
Background:
- Diabetes mellitus (DM) is a global health concern with rising prevalence and severe complications.
- DM is linked to heart disease, nephropathy, neuropathy, and impaired wound healing.
- Systemic inflammation, mediated by innate immune receptors, is implicated in DM pathogenesis.
Purpose of the Study:
- To review the expression and activation of Toll-like receptors (TLRs) in diabetes.
- To elucidate the role of TLRs in mediating inflammation in DM complications.
- To consolidate existing knowledge on TLRs' detrimental effects on heart disease, nephropathy, neuropathy, and wound healing in DM.
Main Methods:
- Literature review of in vitro and in vivo studies.
- Analysis of TLR expression and activation pathways in diabetic models.
- Synthesis of data on TLRs' impact on DM-related organ damage and healing.
Main Results:
- TLRs are key innate immune receptors involved in inflammatory responses in DM.
- Evidence suggests TLRs contribute to the pathogenesis of DM complications.
- Specific TLRs and their signaling pathways are implicated in heart disease, nephropathy, neuropathy, and poor wound healing.
Conclusions:
- TLRs play a significant role in the inflammatory processes underlying DM complications.
- Targeting TLRs may offer a therapeutic strategy for managing DM-related conditions.
- Further research is needed to fully understand and exploit the TLR pathway in diabetes treatment.
