Cell-mediated immunity
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.
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
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.
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
White blood cells, specifically lymphocytes, are responsible for helping to fight invading antigens in the blood. These cells produce antibodies that target and neutralize foreign substances, such as bacteria or viruses. Additionally, white blood cells can mount an immune response to destroy these antigens and prevent infection.
Antibodies recognize antigens by binding to specific molecules on their surface. This binding triggers a series of events that activate the immune response, including the production of more antibodies and the recruitment of immune cells to destroy the antigen.
B cells play a role in the immune response against cancer by producing antibodies that can help target cancer cells for destruction by other immune cells. They do not directly destroy cancer cells themselves, but help to coordinate the immune system's response against cancer.
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.
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.
The part of the immune response that is specific to a particular pathogen is the adaptive immune response. This response involves the activation of lymphocytes, particularly T cells and B cells, which recognize specific antigens presented by the pathogen. B cells produce antibodies that target these antigens, while T cells can directly kill infected cells or help orchestrate the immune response. This specificity allows for a tailored and effective defense against distinct pathogens.
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.

CD4 T cells are activated in the immune response when they recognize antigens presented by antigen-presenting cells, such as dendritic cells. This recognition triggers the CD4 T cells to proliferate and differentiate into effector T cells, which help coordinate and regulate the immune response.
Langerhans cells are the specific cells in the skin that are involved in the immune response. They function as antigen-presenting cells and help to initiate immune reactions by presenting antigens to other immune cells.
