I agree with OP, I always got this card wrong because it did not specify T vs B lymphocytes

like this a lot, will move some to extras and add clarifier in text

source from fa 22 pg 101

I don’t think this is correct. Pg 101 of FA '22 says B cell activation and class switching involves CD40/CD40L, not B7/CD28. B7/CD28 is associated with T-cell activation. After looking at AMBOSS, I’m not convinced the original card is particularly high yield, either. The only place I’ve seen CD40/CD40L mentioned in regards to macrophages or T-cell activation is in research papers and Wikipedia articles. It might just be more confusing than helpful at this point.
