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 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.
How are helper T cells activated in the immune response process?
Helper T 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 helper T cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.
How do B cells get activated in the immune response process?
B cells get activated in the immune response process when they encounter a specific antigen that matches their receptors. This triggers the B cell to divide and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.
How does the activation of B cells occur in the immune response?
B cells are activated in the immune response when they encounter a specific antigen that matches their receptors. This triggers the B cells to multiply and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.

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.
When b cells are activated some mass produce antibodies while other become - to protect the body of a later date?
When B cells are activated, some differentiate into plasma cells that produce antibodies to fight off pathogens in the body at that time. Others differentiate into memory B cells, which remain in the body to provide a faster and stronger immune response upon future encounters with the same pathogen.
What happens immediately AFTER a lymphocyte becomes activated?
Immediately after a lymphocyte becomes activated, it undergoes clonal expansion, rapidly proliferating to produce numerous identical daughter cells. These daughter cells differentiate into effector cells, such as cytotoxic T cells or plasma cells, depending on the type of lymphocyte activated. This process enhances the immune response, enabling the body to effectively target and eliminate pathogens or infected cells. Additionally, some of these activated lymphocytes will become memory cells, providing long-term immunity.
What gives a rise to plasma cells during primary immune response?
B-cells differentiate into plasma cells and memory cells in the primary immune response. The memory cells then produce antibodies.In the secondary, memory cells created in the primary differentiate into plasma cells and secrete antibodies immediately. This is a much faster response, explaining why the secondary response causes a person to suffer less or unnoticeably.
Do activated Tc cells only turn in to cytotoxic T-lymphocytes or do Tc differentiate into memory cells as well?
Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.
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.
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.
