B lymphocytes are associated with (LQ)
- [A] T-cells: - (Markers) .
a. CD3 →Pan-T-cell marker Q
b. CD2 →Receptor for sheep Erythrocyte (E-rosette) Q
c. CD4 →T-helper-inducer cells → Binds to MHC class IIQ
d. CD8 →T-cytotoxic -suppressor cells → Binds to MHC calls I.Q
e. Surface Antigen receptor (TCR) is attached to CD3. Q
- [B] B-cells →
a. CD19 →Pan B-cell marker. Q
b. CD2o/21/22 →B-cell markers Q
- [C] CD34→ stem cell markers.
- [D] Hairy cells → usually B-lymphocytes → but characteristically express CD25 and FMC7 and Acid phosphatase staining resistant to the action of tartrate,
- [E] NK cells →
a. CD56 and CD16 are NK cell marker Q
b. Large granular Lymphocytes Q
c. Kills the viral infected and tumor cell in the absence of prior sensitization and without MHC. Q
