How are T helper cells activated in the immune response process?
T helper cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the T helper cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.

This interaction triggers the helper T cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
What activates helper T cells in the immune response?
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.
How are CD4 T cells activated in the immune response?
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.
How are helper T cells activated in the immune response?
Helper T cells are activated in the immune response when they encounter an antigen-presenting cell that displays a specific antigen on its surface. This interaction triggers the helper T cell to become activated and release signaling molecules that help coordinate the immune response.

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.
How are natural killer (NK) cells activated in the immune response?
Natural killer (NK) cells are activated in the immune response through a process called "priming." This involves the recognition of infected or abnormal cells by NK cell receptors, which then trigger the release of cytotoxic molecules to destroy the target cells. Additionally, cytokines released by other immune cells can also stimulate NK cell activity.
How do dendritic cells activate T cells in the 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.
How do B cells activate T cells in the immune response?
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.
How are regulatory T cells activated and what role do they play in the immune response?
Regulatory T cells are activated by recognizing specific antigens presented by other immune cells. Once activated, they suppress excessive immune responses to prevent autoimmunity and maintain immune tolerance. They play a crucial role in controlling inflammation and preventing immune reactions against self-tissues.
Immune response in which b cells transform into plasma cells secret anti bodies?
This process is known as antibody production or humoral immune response. B cells are activated by antigens, differentiate into plasma cells, and secrete antibodies to target and neutralize specific pathogens. This response is important for the body's ability to defend against infections and develop immunity.
What are activated B cells?
Activated B cells are immune cells that have undergone a process of activation in response to an antigen, typically following interaction with helper T cells. Upon activation, these B cells proliferate and differentiate into plasma cells, which produce antibodies specific to the encountered antigen. They also form memory B cells that provide long-lasting immunity by remaining in the body to respond more rapidly upon future encounters with the same antigen. This process is essential for the adaptive immune response and the development of immunological memory.
