Answer to Question 1

Ans:
A, B, D, E

Feedback:

A butterfly rash, joint pain, pleural effusion, and low levels of blood cellular components are all associated with SLE. Environmental allergies are not noted to be risk factors or associated symptoms of the disease.

Answer to Question 2

Ans:
D

Feedback:

Keratinocytes are now known to be active secretory cells that play an important role in the immunobiology of the skin by communicating and regulating cells of the immune response and secreting cytokines and inflammatory mediators. Gap junctions allow ions and molecules to pass between skin cells, and adherens junctions provide a mechanical connection between cells. Desmosomes are localized patches or plaques that hold two cells tightly together by proteins called cadherins. They are terminal end points on the cell walls of keratinocytes.
