Insights

Immune checkpoint blockade (ICB) therapies can restore T cell function but often fail due to resistance. Targeting transcription factors (TFs) with small molecules offers a promising strategy to enhance anti-cancer immunity.

Area of Science:

  • Immunology
  • Cancer Biology
  • Molecular Biology

Background:

  • Immune checkpoint blockade (ICB) therapies reinvigorate T cell responses but face challenges with non-responders and acquired resistance.
  • Dysfunctional T cells are a major hurdle in achieving durable anti-cancer immunity.
  • Novel strategies are crucial to overcome resistance and broaden the efficacy of immunotherapies.

Purpose of the Study:

  • To review mechanisms underlying T cell dysfunction, with a focus on transcription factor (TF) networks.
  • To explore the dual roles of core TFs in both T cell function and dysfunction.
  • To discuss emerging strategies for targeting TFs to improve anti-cancer immunity.

Main Methods:

  • Literature review of T cell dysfunction mechanisms.
  • Analysis of key transcription factor networks in T cell biology.
  • Review of small molecule modulators targeting TFs for immunotherapy.

Main Results:

  • Identified key transcription factors (TFs) and their complex roles in T cell dysfunction.
  • Highlighted the potential of targeting TF networks to overcome immunotherapy resistance.
  • Emphasized the challenges and promise of small molecule TF modulators.

Conclusions:

  • Transcription factors play critical roles in regulating T cell function and dysfunction.
  • Targeting TFs offers a promising avenue to enhance the efficacy of immune checkpoint blockade therapies.
  • Small molecule modulators represent a challenging but potentially transformative approach to sustained anti-cancer immunity.

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

General Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

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...
