A 34-year-old man who is HIV positive is brought to ...
CD4+ T lymphocytes
Yea i get that, but if the patients CD4 was ~35, how in the world did the CD4 count rise enough to stimulate B cell proliferation...? I don't get it
The only thing i can think of is that:
the cd4 count that is given was taken prior to having started the antiretroviral therapy.
Since the question asks about "improved function", maybe its referring to the therapy actually being effective and its managed to increase cd4 count and function so as to be able to contribute to lymph node enlargement due to myco. avium
