Answer 1

QUESTION 1

NOT true about chemokines?

The correct answer is Are only produced by immune cell. In fact, they can be secreted by epithelial cells

QUESTION 2

Cytokines produced in an inflamed tissue but induce fever by entering the bloodstream and affecting neuronal cells are described to have what type of effect?

In this case, the correct answer is endocrine because the signaling molecule is travelling through the bloodstream in order to reach the target cell. Paracrine is not correct because it is based on a signaling between nearby cells.

QUESTION 3

Complement pathways are activated by recognizing microbial products?

The correct answer is all pathways
