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

T cells secrete chemicals called cytokines such as interferon-gamma, interleukins, and tumor necrosis factor in response to antigens. These chemicals help regulate immune responses by activating other immune cells, promoting inflammation, and coordinating the immune system's response to pathogens.

Do t cells respond to antigens by secreting complements?
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.
In order for antigens to incite the immune response they must be 1 processed 2 reduced 3 combined with other proteins 4 directed?
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.
What process provides many b cells and t cells that are activated against specific antigens?
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.
What are antigens determining blood type carried on?
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.
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
Do t cells respond to antigens by secreting complements?
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.
Which chemicals are secreted by T-helper cells to stimulate b-plasma cells to divide?
These chemicals are called CYTOKINES.
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them called?
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.
What is histamine secreted by?
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.
Which immune cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
What immune system cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
Which is part of a specific immune response?
Looking for antigens is part of a specific immune response.
In order for antigens to incite the immune response they must be 1 processed 2 reduced 3 combined with other proteins 4 directed?
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.
What are the cells that combine with foreign antigens and present them to t cells called?
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.
What cells engulf antigens and present fragments of them on their own surfaces where they can be recognized by cells that will deal with them?
Antigen-presenting cells, such as dendritic cells, macrophages, and B cells, engulf antigens and present fragments of them on their cell surfaces. These antigens are then recognized by T cells, particularly CD4+ helper T cells or CD8+ cytotoxic T cells, which play a key role in initiating an immune response against the antigen.
Langerhans cells are the mechanism of action of which function of skin?
Langerhans cells are a type of dendritic cell found in the skin. They play a critical role in the immune response by capturing and presenting antigens to T cells, which helps to initiate an immune response against pathogens that have breached the skin barrier.
What are antigens determining blood type carried on?
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.
