The mechanisms of NLRP3 inflammasome/pyroptosis activation and their role in diabetic retinopathy

Frontiers in Immunology, Год журнала: 2023, Номер 14

Опубликована: Апрель 25, 2023

In the working-age population worldwide, diabetic retinopathy (DR), a prevalent complication of diabetes, is main cause vision impairment. Chronic low-grade inflammation plays an essential role in DR development. Recently, concerning pathogenesis DR, Nod-Like Receptor Family Pyrin Domain Containing 3 (NLRP3) inflammasome retinal cells has been determined as causal factor. eye, NLRP3 activated by several pathways (such ROS and ATP). The activation NPRP3 leads to secretion inflammatory cytokines interleukin-1β (IL-1β) interleukin-18 (IL-18), pyroptosis, rapid form lytic programmed cell death (PCD). Cells that undergo pyroptosis swell rapture, releasing more factors accelerating progression. This review focuses on mechanisms activate leading DR. present research highlighted some inhibitors NLRP3/pyroptosis novel therapeutic measures treatment.

Angiogenesis during diabetic wound repair: from mechanism to therapy opportunity

Burns & Trauma, Год журнала: 2025, Номер 13

Опубликована: Янв. 1, 2025

Abstract Diabetes mellitus, a pervasive chronic metabolic disorder, is often associated with complications such as impaired wound healing. Various factors, most notably vascular deficiency, govern the repair process in diabetic patients, significantly impeding healing; therefore, angiogenesis and its role have emerged important areas of research. This review aims to delve into mechanisms angiogenesis, effects diabetes on association between repair. will ultimately offer valuable guidance regarding ideal timing treatment clinical setting.

With the global prevalence of diabetes mellitus over recent decades, more patients suffered from various diabetic complications, including ocular surface diseases that may seriously affect quality life and even vision sight. The major include keratopathy dry eye. Diabetic is characterized with delayed corneal epithelial wound healing, reduced nerve density, decreased sensation feeling burning or dryness. eye manifested as reduction tear secretion accompanied discomfort. early clinical symptoms degeneration, suggesting diagnosis should be focused on examination confocal microscopy symptoms. pathogenesis involves accumulation advanced glycation end-products, impaired neurotrophic innervations limbal stem cell function, dysregulated growth factor signaling, inflammation alterations. associated abnormal mitochondrial metabolism lacrimal gland caused by overactivation sympathetic nervous system. Considering important roles dense in homeostatic maintenance cornea gland, further studies neuroepithelial neuroimmune interactions will reveal predominant pathogenic mechanisms develop targeting intervention strategies complications.

Kidney disease is a significant health problem worldwide, affecting an estimated 10% of the global population. encompasses diverse group disorders that vary in their underlying pathophysiology, clinical presentation, and outcomes. These include acute kidney injury (AKI), chronic (CKD), glomerulonephritis, nephrotic syndrome, polycystic disease, diabetic many others. Despite distinct etiologies, these share common feature immune system dysregulation metabolic disturbances. The pathways are intimately connected interact to modulate pathogenesis diseases. responses diseases includes complex interplay between various cell types, including resident infiltrating cells, cytokines, chemokines, complement factors. factors can trigger perpetuate inflammation, causing renal tissue progressive fibrosis. In addition, play critical roles diseases, glucose lipid metabolism, oxidative stress, mitochondrial dysfunction, altered nutrient sensing. Dysregulation contributes progression by inducing tubular injury, apoptosis, Recent studies have provided insights into intricate revealing novel therapeutic targets for prevention treatment Potential strategies modulating through targeting key or inhibiting pro-inflammatory signaling pathways, improving function, nutrient-sensing such as mTOR, AMPK, SIRT1.

Tetrahedral Framework Nucleic Acids Based Small Interfering RNA Targeting Receptor for Advanced Glycation End Products for Diabetic Complications Treatment

ACS Nano, Год журнала: 2023, Номер 17(22), С. 22668 - 22683

Опубликована: Сен. 26, 2023

Complications arising from diabetes can threaten multiple organs. Advanced glycation end products (AGEs) play a significant role in inducing these complications. Highly processed diets and hyperglycemia facilitate the accumulation of AGEs body. Interaction between their main receptor (RAGE) initiates transmission intracellular inflammatory cell death signals, which ultimately lead to To counter AGEs-induced damage, we developed an siRNA-binding tetrahedral framework nucleic acids (TDN) system, termed Tsi, combines potent membrane penetrability serum stability TDN with gene-targeting specificity siRNA-RAGE. Tsi effectively persistently downregulates expression RAGE, thereby suppressing inflammation by blocking NF-κB pathway as well exhibiting antioxidant functions. Furthermore, regulates pyroptosis state macrophages via NLRP3/caspase-1 axis, inhibits spread signals maintains homeostasis. This is great significance for synergistic treatment strategy systemic complications patients refractory hyperglycemia. In summary, this study describes nanomedicine that targets RAGE suppresses AGE-induced inflammation. acid drug holds long-lasting efficacy independent lowering hyperglycemia, provides diabetic age-related diseases.
