Summary
T regulatory (Treg) cells are crucial for healthy immune responses to allergens. These cells inhibit allergic inflammation and are key targets for advancing allergen specific immunotherapy treatments.
Area of Science:
- Immunology
- Allergy Research
- Immunotherapy
Background:
- Allergic disorders involve complex immune responses.
- Allergen specific immunotherapy (AIT) targets these mechanisms.
- T regulatory (Treg) cells play a significant role in immune regulation.
Purpose of the Study:
- To investigate the function of Treg cells in allergic immune responses.
- To understand the role of Treg cells in AIT.
- To review recent advancements in immune regulation related to allergies.
Main Methods:
- Conducted a PubMed search for English-language articles.
- Focused on Treg cells and allergen specific immunotherapy.
- Selected and reviewed relevant scientific literature.
Main Results:
- Treg cells inhibit allergen-specific T(H)2 and T(H)1 cell responses.
- Treg cells suppress IgE production and effector cell activity in allergic inflammation.
- AIT is characterized by diminished allergen-specific T-cell proliferation and cytokine secretion.
Conclusions:
- Treg cells are vital for peripheral tolerance to allergens.
- Further research into Treg cells can lead to safer and more effective AIT.
- Advancements in understanding Treg cells promise improved allergy prevention and treatment.

01:27Tumor Immunotherapy
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.
01:40Cell-mediated Immune Responses
Overview
01:22T 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.

01:24T 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.

01:27Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
