Induction of specific unresponsiveness (tolerance) in peripheral T cells by IL-10 and/or TGF-beta and recovery by cytokines from the tissue microenvironment represent two key steps in specific immunotherapy of allergy and natural exposure to allergens in healthy individuals. IL-10 and TGF-beta elicit tolerance in T cells and thereby control the suppression and development of antigen-specific immunity. Both cytokines also play an important role on the generation of a non-inflammatory IgG4 and IgA type of allergen--specific antibodies during the course of specific immunotherapy. Histamine plays an important role in upper and lower airway inflammation. In addition to its well-characterized effects in the acute inflammatory and allergic responses, histamine regulates several aspects of antigen-specific immune response development. Histamine affects the maturation of dendritic cells and alters their T cell polarizing capacity. Histamine regulates antigen specific Th1 and Th2 cells as well as related antibody isotype responses. Histamine and four different known histamine receptors (HR) display a very complex system and their expression changes according to the stage of cell differentiation as well as microenvironmental influences.

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic 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...
Tumor Immunotherapy01:27

Tumor 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.

Vaccines01:21

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

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 Cell Activation and Clonal Selection01:22

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.
Naive T cells that have not yet encountered an antigen express two primary CD...
