Classical monocytes are characterised as CD14++ CD16-, Intermediate monocytes express CD14++CD16+ and Non-classical monocytes are characterised by CD14+CD16++ expression.
no, thp-1 cells even than you can induce differentiation they do not behave like monocyte (CD14, or CD14CD16). In general differentiation is not similar to macrophages. For example, monocytes are not susceptive to HIV infection, but THP-1 are, Upon differentiation of monocytes they become CD14CD16 positive and are highly susceptible to HIV infection. In contrast, THP-1 differentiation induce resistance to HIV infection. Thus these cells do not behave like monocytes or CD16++. Sorry
