I think its neutrophils because they mention myelosupression and rapidly dividing cells.
Ya, Neutrophils, basophils, macrophages, eosinophils are considered Myeloid cells. While the rest of the T cells are from the Lymphoid lineage, The Immunoglobulins come from B cells ( lymphoid lineage).
Myelosuppression refers to bone marrow suppression as a whole, including lymphocytes. I got it wrong too and no clue why its neutrophils, but I don't think that's why
Maybe they're looking for us to pick "losing innate immunity" (maybe worse than losing adaptive?), which wouldn't refer to complement here since the problem isn't in the liver
Neutropenia: Absolute neutrophil count < 1500 cells/mm3.
Severe infections typical when < 500 cells/mm3.
Causes: Sepsis/postinfection, drugs (including chemotherapy), aplastic anemia, SLE,
Pretty sure the idea is that it's just the fact that you classical follow neutrophils. All cytotoxic T-cell activity is talking about ACTIVITY not counts. NK cells we just don't really measure those I think haha
