When an antigen is bound to a class II MHC protein it can activate what cell?
When an antigen is bound to a class II MHC protein, it can activate helper T cells. Helper T cells play a critical role in initiating and coordinating immune responses by releasing various signaling molecules and activating other immune cells.
How do T-Cells fight infection?
Helper T cells activate killer T cells.
What binds with and releases chemicals that activate B cell and T cell and and macrophages?
Antigen-presenting cells (APCs) such as dendritic cells bind with antigens and present them to B cells, T cells, and macrophages, leading to their activation. This process is crucial for initiating immune responses against pathogens and foreign substances in the body.
B cells interacting with helper T cells are stimulated to differentiate when?
B cells interacting with helper T cells are stimulated to differentiate when the helper T cells provide signals, such as cytokines like IL-4 or IL-21, that activate the B cells. This interaction helps the B cells undergo class switching, somatic hypermutation, and develop into memory B cells or plasma cells, leading to an enhanced immune response.
How do helper t cells get rid of disease?
Helper T cells do not directly eliminate pathogens themselves. Instead, they help activate other immune cells such as B cells and cytotoxic T cells to target and destroy pathogens. Helper T cells release signaling molecules called cytokines that orchestrate the immune response against the disease.
What do the helper t-cells activate?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
What cells do helper T-cells activate?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
Which cell of the immune system is absolutely required for an adaptive immune response in that it helps activate both humoral and cellular immune responses?
Helper T cells

How do the helper T cells first become part of the immune response to invasion by a virus?
T helper cells (CD4 T cells) serve to guide the development of adaptive (acquired) immune responses. Once they are activated and instructed by cells of the innate (natural) immune system, they "help" to activate cytotoxic (CD8) T cells and B cells (antibody producers). In the case of viruses T helper cells, once polarized, will produce signaling molecules (such as IL-2) that alert the CD8 T cells to the infection and will help activate B cells and will instruct them as to which flavor or antibody is best to produce. The CD4 T cells will also release other signaling proteins (such as Interferons) that help get rid of the virus.

What are lymphocytes that coordinate cellular and humoral immune responses?
T helper Cells
What lymphocytes coordinate cellular and humoral immune responses?
t helper cells
What occurs within the t4 cell?
Within a T4 cell, various processes related to the immune response take place. T4 cells are helper T cells that coordinate and regulate the immune system by communicating with other immune cells. They help activate B cells to produce antibodies and activate cytotoxic T cells to destroy infected cells.
Are plasma cells and helper t cells the same thing?
No, plasma cells and helper T cells are different types of immune cells. Plasma cells are a type of B cell that produces antibodies, while helper T cells are a type of T cell that helps activate other immune cells, including B cells.
