if on the dat we are asked which is first to react to a virus...do i put:

a-if its non specific NK cells or interferon?

b. if its specific i put helper T cells right?

ive seen conflicting answers. thanks.

If it is non-specific, then yes, I would put Natural Killer Cells.

As for specific, I would put macrophages, as they would first ingest the pathogen, then display the antigen on their cell surface for recognition by helper T cells.

This may help.
