Term
This ___ serves as a receptor for hep C virus and some parasite entry
Definition
Scavenger receptors
Term
An example of a C-type lectin receptor (CLR) is?

Term
These three cytokines are released by macrophages which travel to the brain and cause the pituitary to release ___ which does what?
Definition
IL-1, IL-6, TNF alpha stimulated pituitary to release ACTH. ACTH then stimulates the adrenal cortex to secrete cortisone to damper inflammatory response.
