Which pair of cytokines induces alternative macrophage activation?

Which interaction is specifically described as essential to strong chronic inflammatory reactions such as granulomatous inflammation?

Which two processes sustain persistent macrophage accumulation at a site of inflammation?

Which disease exemplifies chronic inflammation of the arterial wall induced partly by excessive production and tissue deposition of endogenous cholesterol and other lipids?

Prolonged production of which acute-phase protein is particularly associated with amyloidosis in chronic inflammation?

Which infectious disease should always be excluded as the cause when granulomas are identified?

Which acute-phase protein promotes rouleaux formation by neutralizing the negative surface charge of red cells?

A synovial biopsy from a patient with longstanding rheumatoid arthritis shows lymphocytes, antigen-presenting cells, and plasma cells clustered into structures resembling lymph-node follicles. What are these structures called?

What term describes scarring caused by chronic inflammation in parenchymal organs such as the liver or kidney?

A healing skin wound contains pink, soft, granular tissue composed of proliferating fibroblasts, extracellular matrix, and new blood vessels. What is this tissue called?

Which group of normally quiescent cells can proliferate in response to growth factors during wound healing?

Why does injury to cardiac muscle usually result in a scar?
