Question

B and T lymphocytes may be distinguished from each other by the presence of lineage specific membrane markers termed:

Group of answer choices

CCR5

Complement

CRP

Chemokines

CD

Answer 1

*CCR5-Chemokine receptor 5

This is a seven transmembrane protein similar to G protein coupled receptors.this protein is expressed by T cells but not present in B cells so by this membrane marker we differentiate T cells from B cells.

*Complement-Complement protein are useful in acquired immunity and they produced in liver and their receptors present in white blood cells

C3 complement receptors present on B cells but absent on T cells,So by this C3 complement receptor marker we also differentiate them.

*CD-Cluster of differentiation

This are numerous antigen present on the surface of white blood cells.

Of which CD19 is the cell surface marker of B cells

and CD3 is the cell surface marker of T cells.
