Quantification of the median fluorescence intensity of CD3 and CD4 in mycosis fungoides/Sezary syndrome versus non-neoplastic control cases in peripheral blood.

Peripheral blood involvement by MF/SS has significant implications for prognosis and treatment. Flow cytometry is commonly used to assess MF/SS by analyzing the ratio of CD26- and/or CD7-CD4 + T cells and assessment of immunophenotypic abnormalities. However, distinguishing normal from abnormal cells is not always easy.

HIV-1-Infected CD4+ T Cells Facilitate Latent Infection of Resting CD4+ T Cells through Cell-Cell Contact.

HIV-1 is transmitted between T cells through the release of cell-free particles and through cell-cell contact. Cell-to-cell transmission is more efficient than cell-free virus transmission, mediates resistance to immune responses, and facilitates the spread of virus among T cells. However, whether HIV cell-to-cell transmission influences the establishment of HIV-1 latency has not been carefully explored.
