Question 1

Answer 1

non-immune-mediated inflammation

Question 2

Answer 2

chemokines

Question 3

Lymphocytes and macrophages interact in a ___________ and these interactions play an important role in chronic inflammation.

Answer 3

Bidirectional way

Question 4

How macrophage simulate lymphocyte in bidirectional way?

Answer 4

Macrophage display antigen to T cell, express membrane molecule (costimulators) produce cytokines (lL-12) stimulate T cell response

Question 5

How lymphocyte simulate macrophage in bidirectional way?

Answer 5

Activated T lymphocyte produce cytokines (INF) is a powerful activator of macrophage, promoting antigen presentation and cytokine secretion.
