1. Macrophages express multiple types of receptors on their surface that stimulate phagocytosis of microbes, leading to pathogen internalization and destruction. Many of these receptors, such as Dectin-1, rely on direct recognition of a PAMP on the pathogen surface. However, some receptors that stimulate phagocytosis rely on soluble factors (not associated with the phagocyte membrane) to identify and mark the pathogen for uptake by the phagocyte. One such receptor is:
| a) The class A scavenger receptor | ||
| b) The complement receptor | ||
| c) The mannose receptor | ||
| d) The macrophage C-type lectin receptor | ||
| e) The lipid receptor |
2. Toll-like receptor (TLR) signaling pathways lead to the activation of NFkB and of IRF family transcription factors. Each pathway has multiple steps, beginning with adapter proteins in various combinations. This process will induce inflammatory cytokine gene expression rapidly. The following are such adapter proteins EXCEPT:
| a) MyD88 | |||||||||||||||||
| b) MAL | |||||||||||||||||
