Design a role play in which five classes of immunoglobulins show different functions to provide immunity to human body.
(Hint: Give at least one dialogue showing the function for each class of immunoglobulin. In addition to these five members, human body, patho gens, p cells etc. may be involved in the role play).

Explanation

Human body : I am well protected against you Mr. Pathogen.
Pathogen : How will you protect yourself against me?
Human body: I will call my warriors and they will introduce themselves before you. (Then calls the immunoglobulins)
IgG :I help in the stimulation of phagocytes.
IgA : I protect the body from inhaled and ingested pathogens.
IgM: Activation of B cells is my duty.
IgD:I will be seen in lymphocyte surface as receptors.
IgE : Allergic response needs a mediator and I will look after that job.
