Two major lineages:

Myeloid precursor and lymphoid precursor

1

Two types of T helper cells:

TH1 cells help the CD8+pre-cytotoxic cells.
TH2 cells help B cells

2

Type of the immune system responsible for the maturation of antigen-reactive cells.

Primary response

3

Type of immune system responsible for antigen contact and response

Secondary response

4

Two main type of tissue that disposes worn-out bloodness

Red pulp

5

Two main type of tissue that contains the lymphoid tissue

White pulp

6

Large white cells that can engulf and digest marauding microorganism and other antigenic particles. Some have the ability to present antigen to lymphocytes

Phagocytes

7

Important phagocytes

Monocyte and macrophage

8

Other antigen-presenting cells;

B cells, macrophage, type 1 & 2 dendritic cells

9

Irregularly shoed wbc. Have long threadlike tentacles that enmesh lymphocytes and antigens. Can be found in spleen.

Dendritic cells

10

These are dendritic cells that travel in the skin, picking up antigen and transporting it to lymph nodes. Found in pancreas

Langerhans cells

11

They play a key role in acute inflammatory response

Neutrophils

12

It is a noncirculating counterpart of the basophil. Located in the lungs, skin, tongue, and linings of the nose and intestinal tract. Responsible for the symptoms of allergy.

Mast cell

13

F: SRBC receptor, t cell adhesion/ activation

CD2

14

Signal transduction

CD3

15

Co-recognition of MHC class 2 with TCR, primary receptor of HIV retrovirus

CD4

16

Involved in signaling through TCR and BCR

CD5

17

Involved in T cell proliferation, cell adhesion

CD6

18

Co-recognition of MHC class 1 with TCR

CD8

19

Regulation of B cell growth and proliferation

CD10

20

Granulocytes neutrophil only

CD16b

21

Receptor for LPS and LBS

CD14

22

Mediates signal transduction on NK cells

CD16a

23

Signals transduction regulating B cell responsiveness

CD19

24

Involved in B cell proliferation/activation, part of the signal transduction complex

CD21

25

Regulates IgE synthesis, mediates cytotoxicity by macrophage and eosinophil

CD23

26

Involved in T cell and C cell activation/proliferation

CD27

27

T cell co-stimulatory signal

CD28

28

Regulatory B cell

CD32

29

Negative regulatory role in myeloid hematopoiesis. Important in distinguishing myeloid from lymphoid leukemia.

CD33
