Type 1 Diabetes Research

A Step Into Freedom From T1DM

About Me

Hello

I amShivani Desai

Type 1 diabetes researcher and enthusiast

Welcome to T1DM.org! It is a platform which consolidates my work about type 1 diabetes (T1DM) and its management. This forum invites an open interaction from national and international experts to manage type 1 diabetes, share their knowledge and collaborate to work towards freedom from this painful disease.

This forum includes the papers published by the author in the journals of repute. These papers primarily involve the content related to the etiology and pathophysiology of T1DM, the application of mesenchymal stem cells to manage T1DM and improve the quality of life in patients, and the correlation of diabetes with hepatic dysfunctions. It also includes papers related to the immunological aspects in the journey to prevent and reverse the disease.

With more interaction and collaborations, we can bring an end to T1DM and give a better life to the children who are at risk to develop this immensely agonising disease.

[Video] Ongoing Research on Type 1 Diabetes Mellitus

Insulin is the only available treatment for Type 1 Diabetes Mellitus (T1DM) for over a century now. Globally, scientists are working on different avenues to find a permanent cure for T1DM. Clinical trials are under process, but with little success so far. So where are we today?

Seesaw of Th1 and Th2 in Autoimmune Disorders

Autoimmune diseases stem from imbalances within the functioning of the patient’s immune system. This imbalance is witnessed due to many factors, such as stress, malnutrition, vitamin and mineral deficiencies, inappropriate gut flora, and allergies. These are the common etiologies that are considered while diagnosing any autoimmune disease. 

However, this article describes the basic explanation about the mechanism of T-helper (Th) cells disturbing the immune system, as well as the factors causing this imbalance.

What are Th1 and Th2?

T-helper cells (Th) are an important part of the immune system. They are lymphocytes that recognize foreign pathogens or normal tissues in autoimmune diseases. Cytokines are produced as a response. These Th cells are divided into subgroups:

Th1

Th2

Involved in “cell-mediated” immunity

Involved in “humoral-mediated” immunity

Usually deals with infections by viruses and certain bacteria

Usually deals with infections by bacteria, toxins, and allergens

Body’s first line of defense against pathogens that get inside our cells

Stimulating the production of antibodies in response to extracellular pathogens (those found in blood or other body fluids)

Tend to be pro-inflammatory

Tend to be anti-inflammatory

Involved in the development of organ-specific autoimmune disease

Involved in systemic autoimmune disease and other chronic conditions


In a well-functioning immune system, both groups of these T helper cells work together to keep the system balanced. One side might become more active to eradicate a threat, then settling back to a balanced level. 

Effect of Th Responses in Autoimmune Disease


An alteration in Th1-Th2 balance causes various autoimmune diseases. This is described in the figure.


When the Th1 cells of the immune system are overactive, they can suppress the activity of Th2 and vice versa. This can be problematic, because these two components of the immune system function in a delicately balanced relationship. In the case of autoimmune disease, an imbalance can further the attack on healthy tissue, thereby worsening symptoms. 

Maintaining a balance between Th1 and Th2 immunological responses is paramount to healthy immune functionality.

[Review Paper] Is Type 1 Diabetes Preventable: Population Perspective


Survey Objective: Type 1 diabetes mellitus (T1DM) is growing in incidence over a few years. The objective of this short survey is to report the viewpoint of the general population about their belief if type 1 diabetes mellitus (T1DM) can be prevented. This will further motivate the researchers to accelerate their research to develop vaccines for the prevention and reversal of T1DM.

Methods: A survey was put up on LinkedIn asking a single question “Type 1 diabetes is preventable: Agree or disagree”. The poll was kept open for a period of two weeks and 220 votes were obtained from people belonging to the healthcare sector (n=168) as well as other professions (n=52).

Results: Out of 220 votes, 64% of people agree that T1DM is preventable and the remaining 36% disagree.

Conclusions: Results indicate that majority of people think that T1DM is preventable. Though there is no preventive vaccine at present, there is a hope to formulate such a vaccine that can prevent this autoimmune diabetes.

[Review Paper] Type 1 Diabetes and Covid-19: Managing the Difficult Duo


Coronavirus disease 2019 (COVID-19) has stimulated health concerns globally, especially in diabetes where it has been accompanied by severe outcomes.

Type 2 diabetes mellitus (T2DM) is a chief worry; though, there are a considerable population of patients with type 1 diabetes mellitus (T1DM) also, that too with incomparable concerns during the current COVID-19 pandemic. Some children experience significant complications related to this disease and paediatric deaths have also been reported.

This article describes some key points related to the complications and management of concomitant T1DM and COVID-19.

A Century-long Journey of Type 1 Diabetes Management: From Insulin to …???



Can you answer this question mark in the title? What is the next product coming in the market for reversing or managing type 1 diabetes? 

The history of type 1 diabetes (T1DM) is a longstanding story. However, its management became possible only after the discovery of insulin by Frederick Banting and Charles Best in 1921. With this, scientists started developing hopes to cure this disease. Unfortunately, this goal is yet to be accomplished. This article gives a tour of the various advancements in managing T1DM and how still there is no cure for this perilous disease.

Insulin: The First Weapon to Fight T1DM

The discovery of insulin was not by chance, it was a very well-thought science. The cascade goes as follows:

1889: Joseph von Mering and Oskar Minkowski observed that removing the pancreas from dogs developed diabetes in them, followed by their death shortly.

1910: Sir Edward Albert Sharpey-Schafer projected that the lack of a specific chemical produced by the pancreas is responsible for the development of diabetes. He then named it 'insulin'.

1921: Frederick Banting and Charles Best extracted the pancreatic islet cells from healthy dogs and presented them to the dogs with diabetes which reversed the diabetic condition. This was a stepping stone towards the management of T1DM by the discovery of the hormone, insulin.

Then with the help of two other scientists, they purified insulin extracted from the cow’s pancreas and marked the first treatment option for diabetes.

Finally, in January 1922, this research was translated to humans when 14-year-old Leonard Thompson received an insulin injection to treat his diabetes. This helped him survive for 13 more years and eventually, he died of pneumonia.

And the journey continues this way…

1930s: Introduction of Insulins with longer duration of action.

1936: Sir Harold Percival Himsworth published his research which helped to understand the difference between type 1 diabetes and type 2 diabetes.

1978: Development of Humulin, the first human-based insulin, identical to human insulin in structure.

1986: Insulin pen (prefilled syringes) delivery system was available. This lead to a safe and convenient way to deliver the required dose of insulin.

1990s: Invention of external insulin pumps, which could provide healthier results, more flexibility, and easier treatment management.

1996: Lispro, the first short-acting insulin (onset of action = 15 minutes and duration of action = 2-4 hours), entered the market.

Where We Are Today

Insulin is still the only therapy used to manage type 1 diabetes. Islet transplant is also considered; however, it has to be accompanied with immunosuppressant drugs and still there is difficulty in maintenance of insulin independence; plus, Cadaveric islet transplantation needs multiple donors and is non-affordable to the common man. Extensive research is going on for immune-related therapies; unfortunately, with nothing in the market yet for the patients.

We are working towards a permanent solution to prevent and reverse type 1 diabetes and looking forward to eradicating this disease.
Type 1 to Type None!
