Chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) is the most common B-cell leukemia/lymphoma, effecting >15,000 patients/year. There has been a proposed limited antigenic etiology, at least in some cases, of CLL/SLL based upon immunoglobulin heavy chain stereotypy found across unrelated cases, suggesting viral source may provide such antigenic stimulation. With an established epidemiological link between CLL/SLL and Merkel cell carcinoma (MCC), there has been some interest in investigating a possible leukemogenic role of Merkelcell polyomavirus (MCPyV), which is found in 80% of MCC cases. Recent studies have shown that MCPyV is present in lymphocytes in a small percentage of CLL/SLL cases, but the specific tropism for lymphocytes has not been well-established. In this study, we used quantitative PCR to investigate the presence of MCPyV in fluorescence activated cell sorted purified B- and T-cells from 23 CLL/SLL cases. Three of 23 cases (13%) had detectable MCPyV in T-cells, and none of the cases had detectable MCPyV in B-cells. These findings suggest that MCPyV may have tropism for T-cells in addition to previously reported neoplastic B-cells.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
