Get ready to explore a world of possibilities and discover how research and advancements are shaping the future of diabetes care.
Types of Diabetes
|Type 1 Diabetes
|Type 2 Diabetes
|Type 1 diabetes, also known as insulin-dependent diabetes, occurs when the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This results in the body’s inability to produce sufficient insulin, leading to high blood sugar levels. Type 1 diabetes is commonly diagnosed in children and young adults.
|Type 2 diabetes, also known as non-insulin-dependent diabetes, is the most common form of diabetes. It occurs when the body becomes resistant to the effects of insulin or fails to produce enough insulin to maintain normal blood sugar levels. Type 2 diabetes is often associated with lifestyle factors such as obesity, sedentary lifestyle, and poor diet.
|Management of type 1 diabetes involves lifelong insulin therapy, either through multiple daily injections or the use of an insulin pump. Regular blood sugar monitoring and a healthy diet are also crucial for managing blood sugar levels.
|Management of type 2 diabetes can often be managed through lifestyle modifications, such as adopting a healthy diet, engaging in regular physical activity, and maintaining a healthy weight. In some cases, oral medications or insulin therapy may be prescribed to help control blood sugar levels.
|Complications of type 1 diabetes can include diabetic ketoacidosis, hypoglycemia (low blood sugar), vascular complications, and organ damage.
|Complications of type 2 diabetes can include cardiovascular diseases, peripheral vascular diseases, microvascular diseases, and nerve damage.
Current Treatment Approaches for Diabetes
When it comes to current treatment approaches for diabetes, there are several options available to patients. These treatment approaches aim to manage blood sugar levels and prevent complications associated with diabetes.

###Reference Data (Source: Our Team):
Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8007200/ Stem cell therapy has shown promise as a future treatment for diabetes mellitus (DM). A review of 10 studies found that autologous and allogeneic stem cell therapy is safe and effective for selected individuals with DM. The best outcomes were achieved with the transplantation of bone marrow hemopoietic stem cells (BM-HSCs) for type 1 DM (T1DM) and bone marrow mononuclear cells (BM-MNCs) along with mesenchymal stromal cells (MSCs) for type 2 DM (T2DM). However, stem cell transplantation is not recommended for patients with diabetic ketoacidosis (DKA). Further research is needed to establish stem cell-based therapies as the standard of care for DM. DM is a growing global health problem, with an expected increase in the number of diabetic patients from 463 million in 2019 to 538 million by 2030. T1DM is caused by the autoimmune destruction of insulin-producing beta-cells in the pancreas, while T2DM involves insulin resistance and beta-cell dysfunction. DM can lead to chronic complications, including microvascular and macrovascular diseases, with high morbidity and mortality rates. Current treatments for DM, such as exogenous insulin and hypoglycemic agents, can control hyperglycemia but do not prevent complications or mimic the secretion of endogenous insulin. Alternative modalities, such as stem cell therapy, islet cell transplantation, pancreas transplantation, and anti-CD3 monoclonal antibodies, have been approved for clinical use. However, islet cell transplantation has limitations, including limited donor supplies. The review found that stem cell therapy, particularly BM-HSC transplantation for T1DM and BM-MNC transplantation with MSCs for T2DM, showed the most promising results. These therapies were relatively safe and effective for selected individuals with DM. However, patients with DKA should not undergo stem cell transplantation. Overall, stem cell-based therapies have the potential to be a future standard of care for DM. Further research is needed to validate these findings and establish the safety and efficacy of stem cell therapy for DM treatment. Source: https://www.nature.com/articles/pr2006129 Type 1 and type 2 diabetes are both characterized by a deficit in beta-cell mass, leading to insufficient insulin secretion. Current treatments include pancreas and islet transplantation, but the shortage of donor organs limits this option. Recent evidence shows a decline in beta-cell function after islet transplantation, requiring patients to revert to insulin treatment within a few years. This article reviews recent progress in generating and differentiating human embryonic stem cells into beta-cells. Glucose homeostasis relies on regulated insulin secretion by pancreatic beta-cells. In a healthy state, insulin is secreted at a rate of about 2 pmol/kg/min under fasting conditions, which increases by 5-10 times after a meal. This requires normally functioning beta-cells and an adequate number of them, known as beta-cell mass. The human pancreas contains approximately one million islets, each containing about two thousand beta-cells, constituting around 1.5% of the total pancreatic mass. A reduction in beta-cell mass leads to hyperglycemia. Type 1 diabetes is caused by the autoimmune destruction of beta-cells. Studies show a decline in insulin secretion before the onset of hyperglycemia, indicating a decline in beta-cell mass. Once hyperglycemia develops, up to 90%
