B cell helper T cells and type 1 diabetes

Area of Science:

• Immunology
• Endocrinology
• Autoimmune Diseases

Background:

• Type 1 diabetes (T1D) is an autoimmune disease causing pancreatic beta cell destruction.
• While T cells are primary drivers, B cells and autoantibodies are key indicators before T1D onset.
• Helper T cell subsets, including follicular T helper (Tfh) and peripheral T helper (Tph) cells, are implicated in antibody-associated disorders.

Purpose of the Study:

• To review the role of B cell helper T cell subsets in type 1 diabetes pathogenesis.
• To highlight the involvement of Tfh and Tph cells in the autoimmune process of T1D.

Main Methods:

• Literature review of current research on T helper cell subsets and type 1 diabetes.
• Analysis of the involvement of CXCR5+ Tfh cells and CXCR5- Tph cells in autoimmune diabetes.

Main Results:

• B cells and autoantibodies are present before T1D diagnosis.
• Tfh and Tph cells provide helper functions to B cells, contributing to autoimmunity.
• These T cell subsets are increasingly recognized for their role in T1D development.

Conclusions:

• Follicular T helper (Tfh) and peripheral T helper (Tph) cells are critical players in type 1 diabetes pathogenesis.
• Understanding these B cell helper T cells offers potential therapeutic targets for T1D.
• Further research into Tfh and Tph cell function is essential for managing T1D.
