lymphocytes<br />

- Deals with parasitic infection.<br />

- Modulate allergic inflammatory response<br />

e.g BA, Hay fever<br />

- Release of histamine for inflammatory<br />

response.<br />

- Attacks bacterial & fungal cells<br />

- Most common cell seen in early acute<br />

inflammation<br />

- Life span 4-5 days.<br />

- Pathogen & cellular debris phagocytosis.<br />

- Antigen presenting cells & ++ of T-cells.<br />

Both<br />

- Migrate from blood to tissues where it<br />

differentiates into tissue macrophages<br />

( Kupffer cells in liver) & dendritic cells<br />

Phagocytosis Mobile<br />

1. Release of antibodies<br />

2. Help in ++ of T-cells. Degranulation Mobile<br />

1. CD4 (T-helper cells) ++ B &T cells<br />

2. CD8 (cytotoxic T-cells) : virus-infeted &<br />

tumour cells<br />

3. Suppressor T- cells resume normal<br />

immunity after dealing with infection to<br />

prevent autoimmunity.<br />
