Abnormal expression of AgNORs and cyclin B1 in lymphocytes from HIV-infected patients.

DNA content, assessed by PI staining, AgNOR number and area of distribution, and cyclin B1 intracellular concentration, expressed as pixel intensity of protein bands isolated by Western blot, in selected experiments performed on peripheral blood lymphocytes isolated from healthy controls (panel A) and HIV-infected patients (panel B). The numeric results represent the mean of 20 patients and 20 uninfected controls.
