Recent data have indicated the emerging role of glomerular autophagy in diabetic kidney disease. We aimed to assess effect SGLT2 inhibitor empagliflozin, DPP4 linagliptin, and their combination, on a model type 2 diabetes. Eight-week-old male db/db mice were randomly assigned treatment with empagliflozin–linagliptin or vehicle for 8 weeks. Age-matched non-diabetic db/+ acted as controls. To estimate autophagy, immunohistochemistry beclin-1 LAMP-1 was performed. Podocyte assessed by counting volume density (Vv) autophagosomes, lysosomes autolysosomes transmission electron microscopy.

Based on global estimates, almost 10% of adults have diabetes, whom 40% are estimated to also chronic kidney disease (CKD). Almost 2 decades ago, treatments targeting the renin-angiotensin system (RAS) were shown slow progression disease. More recently, studies reported additive benefits antihyperglycaemic sodium-glucose co-transporter-2 inhibitors in combination with RAS both CKD and cardiovascular outcomes. However, these recent data showed that patients continue progress failure or die from kidney- cardiovascular-related causes. Therefore, new agents needed address this continuing risk. Overactivation mineralocorticoid (MR) receptor contributes inflammation fibrosis, suggesting it is an appropriate treatment target diabetes CKD.

Diabetic nephropathy is a common complication of type I and II diabetes, in which renal glomeruli are destroyed, resulting damage, proteinuria, hypertension. Apoptosis, autophagy, necroptosis 3 forms programmed cell death that have been implicated the pathogenesis diabetic nephropathy. Apoptosis podocytes leads to glomerular injury podocyte depletion, associated with proteinuria structural damage Additionally, epithelial cells proximal convoluted tubules also undergo apoptosis nephropathy, leading tubular atrophy, causes depletion subsequent formation atubular association loss function.

Cardiac fibrosis is a serious health problem because it common pathological change in almost all forms of cardiovascular diseases. characterized by the transdifferentiation cardiac fibroblasts (CFs) into myofibroblasts and excessive deposition extracellular matrix (ECM) components produced activated myofibroblasts, which leads to fibrotic scar formation subsequent dysfunction. However, there are currently few effective therapeutic strategies protecting against fibrogenesis. This lack largely molecular mechanisms remain unclear despite extensive research. The Janus kinase/signal transducer activator transcription (JAK/STAT) signaling cascade an extensively present intracellular signal transduction pathway can regulate wide range biological processes, including cell proliferation, migration, differentiation, apoptosis, immune response. Various upstream mediators such as cytokines, growth factors hormones initiate transmission via this play corresponding regulatory roles. STAT3 crucial player JAK/STAT its activation related inflammation, malignant tumors autoimmune illnesses. Recently, JAK/STAT3 has been spotlight for role occurrence development promote proliferation CFs production ECM proteins, thus leading fibrosis.
