For any one cell the cytokine-secreting activation state is short-lived, lasting between 4 - 40 hours. After this time these cells either die, or mature into the long-lived memory cells. The proliferation of T cells continues until antigen disappears.

*Dendritic cells present antigen to [[Lymphocytes - WikiBlood#T cells|T cells]]
 +
 +
*Circulating monocytes differentiate to form immature dendritic cells called '''Langerhans Cells'''
 +
 +
*Langerhans cells sample the tissue fluid by endocytosis
 +
**Foreign organisms are internalised
 +
 +
*The Langerhans cells leave the epithelium and travel via the afferent lymph. They are now called '''Veiled Cells'''
 +

*Veiled cells enter the paracortical region of the [[Lymph Nodes - Anatomy & Physiology|lymph node]] where they present antigen to [[Lymphocytes - WikiBlood#T cells|T cells]]. They are now called '''Interdigitating Dendritic Cells'''
