pre-B-cell receptor

Biology; Immunology

Expression of the pre-B-cell receptor, or pre-B-cell receptor complex, is a critical event in B-cell development. Expression of this receptor, which is a complex of at least five ...

armed effector T cells

Biology; Immunology

In this book, we have termed primed effector T cells armed effector T cells, because these cells can be triggered to perform their effector functions immediately on contact with ...

C-reactive protein

Biology; Immunology

C-reactive protein is an acute-phase protein that binds to phosphorylcholine, which is a constituent of the C-polysaccharide of the bacterium Streptococcus pneumoniae, hence its ...

blood typing

Biology; Immunology

In transfusion medicine, blood typing is used to determine whether donor and recipient have the same ABO and Rh blood group antigens. A cross-match, in which serum from the donor ...

immunofluorescent microscopy

Biology; Immunology

There are three ways of detecting molecules in tissues: immunofluorescent microscopy that reveals the presence of any molecule against which you have a specific antibody; ...

protein kinases

Biology; Immunology

Protein kinases add phosphate groups to proteins, and protein phosphatases remove these phosphate groups. Enzymes that add phosphate groups to tyrosine residues are called protein ...

helper CD4 T cells

Biology; Immunology

Helper CD4 T cells are CD4 T cells that can help B cells make antibody in response to antigenic challenge. The most efficient helper T cells are also known as TH2 cells, which ...
