Cytokines such as interferrons and interleukins are secreted by the T cell in response to antigen. These chemicals are also secreted by B cells, dendrictic cells and natural killer cells.
These chemicals are signalling agents that modulate (or properly control) the immune response
No, T cells respond to antigens by directly destroying infected cells or by producing cytokines to help coordinate the immune response. Complements are a group of proteins that are part of the innate immune response and are mainly secreted by macrophages and other immune cells to help enhance the immune response.
Antigens incite the immune response by being processed and presented by antigen-presenting cells, such as dendritic cells, to T cells. Once presented, the antigens can activate specific immune responses, leading to the generation of memory cells and effector cells that target the antigen. Antigens that are not processed, reduced, or combined with other proteins may not effectively stimulate the immune system.
The process of clonal selection in the immune system produces numerous B cells and T cells that are activated in response to specific antigens. This involves the proliferation of cells that have receptors capable of binding to a particular antigen, resulting in an amplified response to combat the invading pathogen.
Antigens determining blood type are carried on the surface of red blood cells. These antigens are proteins or sugars that can trigger an immune response if they are not recognized by the body's immune system.

No, T cells respond to antigens by directly destroying infected cells or by producing cytokines to help coordinate the immune response. Complements are a group of proteins that are part of the innate immune response and are mainly secreted by macrophages and other immune cells to help enhance the immune response.
These chemicals are called CYTOKINES.
Histamine is primarily secreted by basophils and mast cells in response to allergens or injury. It is also produced by enterochromaffin-like cells in the stomach.
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.

Looking for antigens is part of a specific immune response.
Dendritic cells activate T cells in the immune response by presenting antigens to the T cells. This interaction triggers the T cells to become activated and initiate an immune response against the specific antigen.
Helper T cells in the immune response are activated by antigens presented by antigen-presenting cells, such as dendritic cells. This activation process helps coordinate and regulate the immune response against pathogens.
B cells activate T cells in the immune response by presenting antigens to T cells. This interaction triggers the T cells to become activated and multiply, leading to a coordinated immune response against the invading pathogen.
Antigens incite the immune response by being processed and presented by antigen-presenting cells, such as dendritic cells, to T cells. Once presented, the antigens can activate specific immune responses, leading to the generation of memory cells and effector cells that target the antigen. Antigens that are not processed, reduced, or combined with other proteins may not effectively stimulate the immune system.
Those cells are called antigen-presenting cells (APCs). They include dendritic cells, macrophages, and B cells. Their role is to ingest foreign antigens, process them, and present them to T cells to initiate an immune response.
