Role of IL-10 Receptor Signaling in the Function of CD4+ T-Regulatory Type 1 cells: T-Cell Therapy in Patients with Inflammatory Bowel Disease

Critical Reviews in Immunology
Shiwa SoukouSamuel Huber

Abstract

Inflammatory bowel disease (IBD) is caused by the interplay of various factors. It occurs in genetically susceptible people due to dysregulated immune responses to several unknown antigens, including those derived from the commensal microbiota. Effector T-helper cells, especially TH17 cells, are considered a major driver of disease progression. The endogenous resident counterparts of effector T-helper cells are the regulatory T cells, mainly Foxp3+ Treg cells and type 1 regulatory (TR1) T cells. Both have strong immune regulatory capacity and can terminate immune responses. Interestingly, the expression of IL-10 receptor on regulatory T cells has a high impact on the regulatory capacity of these cells. Inflammatory bowel disease is becoming a global health issue. No curative therapy is currently available. However, initial clinical trials have been conducted successfully, proving the safety of a regulatory T-cell-based therapy. This therapy might lead to long-lasting remission and to a possible cure for IBD. This review provides a summary of the current findings and the outcome of the clinical trials based on T-cell therapy for IBD and for other inflammatory conditions.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
