(a)
To determine:
The method by which the immune system differentiates foreign cells from cells deemed as self.
Introduction:
The host has developed three lines of defense systems in which some are innate and nonspecific and some are acquired and specific. Non-specific host defense system protects the host from all pathogens whereas specific host defense system protects from specific pathogens. The three lines of defense system are the first line, second line and third line of the defense system.
(b)
To determine:
If viral infection might increase the chances of type I diabetes and explain this situation with a hypothesis and the role of PAMPs in this process.
Introduction:
Insulin is produced by the islets of Langerhans in the pancreas. Insulin regulates the concentration of blood glucose when the concentration is high. It causes the liver to convert excess glucose to glycogen, hence reducing the blood glucose concentration.
