“One of the most remarkable aspects of T cells and B cells is that once an innate cell presents them with antigen, they can remember it for the rest of your life.”
David R. Montgomery and Anne Biklé, The Hidden Half of Nature, W.W. Norton, 2016.
The authors are telling me that I must regard this fact as remarkable. If the fact is remarkable, they ought to convey it in such a way that I find it remarkable on my own.
Also, the construction “aspect… is that…” is clumsy and serves no purpose. The word “aspect” is less than satisfactory for what is meant. “Aspect” is more appropriate for architecture. “Characteristics” would be better here. But not even that word is needed.
Better: “Innate cells present antigens to T and B cells. Then the T and B cells remember those antigens for the rest of your life.”
Is that remarkable? You tell me.
