Place the following events in order for the activation process of our T cells and B cells

1.T cells secrete cytokines
2.T cells become activated
3.Antibodies get secreted
4.Cell displays antigen on its surface
5.B cells become activated

Answer 1

T and B cell activation involves distinct steps beginning with antigen presentation, followed by activation of B and T cells, cytokine secretion by T cells, and ultimately the secretion of antibodies by B cells.

Step-by-step explanation:

The process of activation of B cells and T cells occurs in a specific sequence, which ensures a precise immune response. Below is the proper order of events for B and T cell activation:

1. Cell displays antigen on its surface.
2. B cells become activated.
3. T cells become activated.
4. T cells secrete cytokines.
5. Antibodies get secreted.

Initially, an antigen-presenting cell, such as a B cell, displays the antigen on its surface. This allows the B cell to become activated when its surface immunoglobulin recognizes the antigen. Following this, a helper T cell then binds to the B cell and becomes activated. Subsequently, the activated T cell secretes cytokines that facilitate the activation and proliferation of the B cell into plasma cells. Eventually, these plasma cells secrete antibodies that will bind to the antigen and aid in its neutralization or destruction.
