Studies on nucleoli in rosetting T and B lymphocytes of the human peripheral blood.
The incidence of various nucleolar types was studied in human rosetting lymphocytes to provide an information on nucleolar types present in T and B lymphocytes of the peripheral blood. The results clearly demonstrate that both T and B lymphocytes of the peripheral blood mostly contain ring shaped nucleoli ("resting nucleoli") and less frequently other nucleolar types such as nucleoli with nucleolonemata or compact nucleoli ("active nucleoli") and micronucleoli ("inactive nucleoli"). Since all known nucleolar types and particularly micronucleoli may be observed in both T and B lymphocytes, nucleoli in these cells cannot indicate the type or origin of these cells but simply the state of the nucleolar RNA synthesis.
