Assess the twelve subsequent statements describing the hypothetical phenotypic characteristics of these unique macrophages as either factually correct (= true) or incorrect (= false):

1. A reduced sensitivity to low levels of LPS, but an ability to respond to high levels of LPS.
2. A reduced sensitivity to unmethylated CpG oligonucleotides.
3. An increased sensitivity to unmethylated CpG oligonucleotides.
4. Heightened responses to viral infection due to increased activation of IRF (interferon regulatory factors) genes.

5. Diminished responses to viral infection due to decreased activation of IRF (interferon regulatory factors) genes.
6. A partial inability to phagocytose opsonized bacteria.
7. A total inability to phagocytose opsonized bacteria.

8. A complete failure to produce cytokines in response to LPS.
9. An increased ability to present antigens in the context of MHC class I molecules. 10. A decreased ability to present antigens in the context of MHC class I molecules. 11. An increased ability to present antigens in the context of MHC class II molecules. 12. A decreased ability to present antigens in the context of MHC class II molecules.
