Diabetes Mellitus: Overview and Type I Subtype

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Background:

Type 1 diabetes (T1D) affects millions globally, with current treatments like tolerogenic vaccines and beta cell replacement requiring systemic immunosuppression.
Systemic immunosuppression carries significant patient risks, highlighting the need for localized and targeted therapeutic strategies.

Purpose of the Study:

To review immunomodulatory biomaterial platforms for developing T1D tolerogenic vaccines and beta cell replacement devices.
To explore how biomaterials can achieve localized immune tolerance and support cell-based therapies for T1D.

Main Methods:

Discussion of nano- and microparticle platforms for delivering tolerogenic agents and autoantigens.
Examination of bulk biomaterials for inducing immune tolerance.
Review of biomaterials for drug delivery and immunoisolation in cell therapy and islet transplantation.

Main Results:

Biomaterials can be engineered to deliver therapeutic agents and modulate immune responses locally.
Nano- and microparticles show potential as artificial antigen-presenting cells and for targeted delivery.
Bulk biomaterials and immunoisolation devices offer strategies for immune tolerance and cell protection.

Conclusions:

Immunomodulatory biomaterials present a versatile toolkit for advancing T1D treatment strategies.
Biomaterial-based approaches can potentially reduce the need for systemic immunosuppression in T1D therapies.
Synergistic development across fields holds promise for novel T1D cures.
