T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

    Summary

    Coeliac disease involves a specific suppressor T cell dysfunction in responding to gluten, not a general immune defect. This finding helps understand coeliac disease pathogenesis.

    Area of Science:

    • Immunology
    • Gastroenterology

    Background:

    • Coeliac disease is an immune-mediated disorder triggered by gluten.
    • The role of specific T lymphocyte populations in coeliac disease pathogenesis is not fully understood.

    Purpose of the Study:

    • To investigate the function of suppressor T cells in coeliac disease immune responses to gluten.
    • To determine if coeliac disease involves a generalized T lymphocyte defect or a gluten-specific dysfunction.

    Main Methods:

    • Utilized a T lymphocyte direct migration inhibition factor test.
    • Assayed immune responses to gluten and purified protein derivative in coeliac patients and controls.
    • Employed co-culture experiments with T cells from different donor groups.

    Main Results:

    Published on: April 21, 2015

    • Coeliac T cells showed impaired suppression of gluten-induced migration inhibition, which was abrogated by normal T cells.
    • Coeliac T cells retained the ability to suppress responses to purified protein derivative.
    • Normal T cells pretreated with mitomycin C lost their ability to abrogate coeliac T cell-mediated inhibition.

    Conclusions:

    • Coeliac T cells exhibit a specific dysfunction in suppressing immune responses to gluten.
    • The findings support a hypothesis of gluten-specific suppressor T cell dysfunction in coeliac disease pathogenesis.
    • Results suggest coeliac disease is not caused by a generalized T lymphocyte defect.
