Summary
Regulatory T cells (Tregs) are crucial for immune balance, suppressing autoimmunity and inflammation. Emerging research reveals their non-immune roles in metabolism, tissue repair, and angiogenesis, vital for health and disease.
Area of Science:
- Immunology
- Cell Biology
- Metabolic Research
Background:
- A healthy immune system relies on a balance between immune activation and tolerance.
- Regulatory T cells (Tregs) are key regulators of this balance, preventing autoimmunity.
- Dysfunctional Tregs are linked to autoimmune diseases in mice and humans.
Approach:
- This review synthesizes current literature on Treg functions.
- Focuses on both established immunoregulatory roles and newly identified non-immune functions.
- Highlights Treg involvement in metabolism, stem cell maintenance, tissue repair, and angiogenesis.
Key Points:
- Tregs suppress adaptive and innate immune responses to control autoimmunity and inflammation.
- Tregs exhibit non-canonical functions beyond immune suppression.
- These non-immune functions include modulating metabolism, supporting stem cells, promoting tissue repair, and driving angiogenesis.
Conclusions:
- Tregs play a dual role in health and disease, encompassing both immune suppression and non-immune modulation.
- Understanding the diverse, non-canonical functions of Tregs is critical for developing effective Treg-targeted therapies.
- Treg-directed interventions may benefit from considering their broader roles in tissue homeostasis and repair.

01:24T Cell Types and Functions
1.2K
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.

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

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.

622
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
