What do white blood cells use to help identify foreign substances?

B cells bearing antibodies and T cells bearing ab or gd receptors recognize the appearance of an invader in the body in different ways. B cell antibodies bind to the invading particle, such as a bacterium, in the form in which it enters the body.

How do white blood cells recognize pathogens?

If a pathogen enters your body, white blood cells of your immune system quickly recognise its foreign antigens. This stimulates specific lymphocytes to grow, multiply and finally produce antibodies that will stick to the antigens on the invading pathogens and destroy them.

What is used to help identify cells in the body?

Human leukocyte antigens (HLA) are a group of identification molecules located on the surface of all cells in a combination that is almost unique for each person, thereby enabling the body to distinguish self from nonself. This group of identification molecules is also called the major histocompatibility complex.

How do white blood cells make antibodies?

Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.

How can I raise my white blood cells fast?

Foods high in protein, such as lean meats and poultry, are high in zinc — a mineral that increases the production of white blood cells and T-cells, which fight infection. Other great sources of zinc are oysters, nuts, fortified cereal, and beans.
