Are B cells or T cells more important?

Unlike T-cells and macrophages, B-cells don’t kill viruses themselves. Actually, B-cells are as important as T-cells and are much more than just a final clean-up crew. They make important molecules called antibodies. These molecules trap specific invading viruses and bacteria.

In respect to this, do B cells need T cells?

Memory B cell activation begins with the detection and binding of their target antigen, which is shared by their parent B cell. Some memory B cells can be activated without T cell help, such as certain virus-specific memory B cells, but others need T cell help.

Similarly, how do B cells and T cells work together?

Your body can then produce the most effective weapons against the invaders, which may be bacteria, viruses or parasites. Other types of T-cells recognise and kill virus-infected cells directly. Some help B-cells to make antibodies, which circulate and bind to antigens. A T-cell (orange) killing a cancer cell (mauve).

What are B cells and T cells in the immune system?

T cells and B cells T cells (thymus cells) and B cells (bone marrow- or bursa-derived cells) are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity (relating to antibodies).

Why are there many types of B and T cells?

An important difference between T-cells and B-cells is that B-cells can connect to antigens right on the surface of the invading virus or bacteria. This is different from T-cells, which can only connect to virus antigens on the outside of infected cells. Your body has up to 10 billion different B-cells.
