T lymphocyte subset distribution of sooty mangabey NKT lymphocytes.

<p>A) Representative contour plots showing surface expression of CD4 and CD8 molecules on <i>ex vivo</i> circulating T and Vα24⁺CD1d TM⁺ NKT lymphocytes in two sooty mangabeys (SM #1 and SM #2). B) Contour plots showing surface expression pattern of CD4 and CD8 molecules on representative NKT clones. C) Distribution of CD4⁺ (CD4⁺8⁻), CD8⁺ (CD8⁺4⁻), DN (CD4⁻8⁻) and DP (CD4⁺8⁺) T lymphocyte subsets in <i>ex vivo</i> NKT lymphocytes in 13 SIV-negative sooty mangabeys (left panel) and in 57 NKT clones derived from sorted 6B11⁺ T lymphocytes of one SIV-negative sooty mangabey (right panel).
