B cells mark the virus or paracite as unknown the killer t cells attack and destroy the virus.
B cells mark the virus or paracite as unknown the killer t cells attack and destroy the virus.
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
Nude vs. SCIDAll nude mice are T cell deficient. That is the minimum requirement to host a human tumor graft. SCID mice are also T cell deficient, and are B cell deficient too.

B lymphocyte (B Cell)
Individuals with both B-cell and T-cell deficiencies are said to have severe combined immune deficiency (SCID).
Helper T cell
The first contact of a T or B cell with its specific antigen is called priming. It causes differentiation into effector T or B cells.
suppressor T-cells
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens

Thymus Lymphocytes could be roughly divided into two categories. B cell and T cell. Though they both originate from the bone marrow, T cell migrate to the" thymus," where it reach maturity while B cell got mature in the bone. That is, T stands for thymus. However, B doesn't mean "bone" actually, for B cell was first discovered in the "bursa of Fabricius" in a bird.
