Ex vivo gene expression and miRNA profiling of Eomes Tr1-like cells suggested that they represent a differentiation stage that is intermediate between Th1-cells and cytotoxic CD4 T-cells. Several microRNAs were downregulated in Eomes Tr1-like cells that might inhibit Tr1-cell differentiation. In particular, miR-92a targeted Eomes, while miR-125a inhibited IFN-g and IL-10R expression.

Unlike conventional CD4+ T cells, which are phenotypically and functionally plastic, invariant NKT (iNKT) cells generally exist in a terminally differentiated state. Naïve CD4+ T cells can acquire alternative epigenetic states in response to different cues, but it remains unclear whether peripheral iNKT cells are epigenetically stable or malleable. Repetitive encounters of liver-resident iNKT cells (LiNKTs) with alpha-galactosylceramide (αGalCer)/CD1d-coated nanoparticles (NPs) can trigger their differentiation into a LiNKT cell subset expressing a T regulatory type 1 (TR1)-like (LiNKTR1) transcriptional signature.

Involvement of aryl hydrocarbon receptor in the aflatoxin B and fumonisin B effects on in vitro differentiation of murine regulatory-T and Th17 cells.

Article Synopsis
  • Aflatoxin B (AFB) and fumonisin B (FB) are harmful mycotoxins found in cereals that can increase the risk of liver cancer, yet their combined effects have not been extensively researched.
  • This study investigated how different concentrations of AFB and FB, as well as their mixtures, impact the differentiation of immune cells in mouse spleen, focusing on regulatory T cells (Treg) and Th17 cells, and the role of the aryl hydrocarbon receptor (Ahr) in this process.
  • The results showed that AFB and AFB-FB mixtures influence immune cell differentiation and immunotoxicity through Ahr signaling, potentially enhancing the risk of immune suppression and contributing to tumor growth evasion when these

Repeated immunization with ATRA-containing liposomal adjuvant transdifferentiates Th17 cells to a Tr1-like phenotype.

In many autoimmune diseases, autoantigen-specific Th17 cells play a pivotal role in disease pathogenesis. Th17 cells can transdifferentiate into other T cell subsets in inflammatory conditions, however, there have been no attempts to target Th17 cell plasticity using vaccines. We investigated if autoantigen-specific Th17 cells could be specifically targeted using a therapeutic vaccine approach, where antigen was formulated in all-trans retinoic acid (ATRA)-containing liposomes, permitting co-delivery of antigen and ATRA to the same target cell.

Treg in inborn errors of immunity: gaps, knowns and future perspectives.

Regulatory T cells (Treg) are essential for immune balance, preventing overreactive responses and autoimmunity. Although traditionally characterized as CD4+CD25+CD127FoxP3, recent research has revealed diverse Treg subsets such as Tr1, Tr1-like, and CD8 Treg. Treg dysfunction leads to severe autoimmune diseases and immune-mediated inflammatory disorders.

Cytotoxic CD4 T cells in the mucosa and in cancer.

Front Immunol

September 2024

Center for Immunology, Masonic Cancer Center, Minneapolis, MN, United States.

CD4 T cells were initially described as helper cells that promote either the cellular immune response (Th1 cells) or the humoral immune response (Th2 cells). Since then, a plethora of functionally distinct helper and regulatory CD4 T cell subsets have been described. CD4 T cells with cytotoxic function were first described in the setting of viral infections and autoimmunity, and more recently in cancer and gut dysbiosis.
