Question

Match the term in column A with its description in column B.

Column A	Column B
___a. CCP modules	1. expressed in centrocytes and prevents apoptosis
___b. ICAM-1	2. associated with the development of swollen lymph nodes
___c. CR2	3. required to induce production of activation-induced cytidine deaminase
___d. BLIMP-1	4. expressed on B cells, follicular dendritic cells, and subcapsular sinus macrophages and binds C3d
___e. CD40 ligand	5. CR2-associated and needed for binding to C3d-tagged antigens
___f. Bcl-xL	6. controls lymphoblast differentiation by acting as a transcription factor
___g. germinal center reaction	7. binds to LFA-1 on T cells and fortifies cognate B–T interactions
___h. CD69	8. early indicator of B-cell activation and repressor of SIP receptor expression

Answer 1

Column A	Column B
CCP Modules	CR2 associated and needed for binding to c3d tagged antigens
ICAM - 1	binds to LFA - 1 on T cells and fortifies cognate B- T interactions
CR 2	Expressed on B cells, follicular Dendritic cells, subcapsular sinus macrophages and binds c3d
BLIMP 1	Controls Lymphoblast differentiation by acting as transcription factors
CD 40 Ligand	required to induce production of activation induced cytidine deaminase
Bcl- xL	expressed in centrocytes and prevent apoptosis
germinal centre reaction	associated with the development of swollen lymph nodes
CD 69	early indicator of B cell activation and repressor of S1P receptor expression
