Explains about constant contributors to immune response (1-5)
I believe the answer is:
t-cells
'constant contributors to immune response' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'explains about' is the wordplay.
I cannot really see how this works, but
'about' could be 'c' (circa) and 'c' is found in the answer.
The remaining letters 'tells' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
I've seen this clue in The Guardian.
