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
@hayayah you were being lazy.. smh..
Homie started anti-retroviral therapy. HIV infects CD4 T-Cells through either CCR5 or more commonly CXCR4. Because of anti-retrovirals start working, HIV isnt able to infect anymore CD4 T cells. Thus CD4 t lymphocytes levels start to rise and are able to active B cells.
